Investment Behavior and the Negative Side of Emotion
Abstract
Can dysfunction in neural systems subserving emotion lead, under certain circumstances, to more advantageous decisions? To answer this question, we investigated how normal participants, patients with stable focal lesions in brain regions related to emotion (target patients), and patients with stable focal lesions in brain regions unrelated to emotion (control patients) made 20 rounds of investment decisions. Target patients made more advantageous decisions and ultimately earned more money from their investments than the normal participants and control patients. When normal participants and control patients either won or lost money on an investment round, they adopted a conservative strategy and became more reluctant to invest on the subsequent round; these results suggest that they were more affected than target patients by the outcomes of decisions made in the previous rounds.
... Experimental results also confirmed a positive relationship between trait anxiety and gambler performance and even showed that high emotional control would reduce gambler's outcomes (Werner et al. 2009). Extensive experiments in patients with a lesion in the region of the brain that controls emotions produced more favorable results than healthy patients (Shiv et al. 2005a(Shiv et al. , 2005b. Affect also created the illusion of control (Alloy et al. 1981;Alloy and Abramson 1982;Mesken et al. 2005). ...
... Other emotions, such as anger, also encourage a sense of being able to govern outcomes (Lerner et al. 2015;Lerner and Keltner 2001). People with emotional problems also make bolder decisions and obtain more significant potential gains or losses than ordinary people (Shiv et al. 2005b). ...
... Other studies also discovered that past failure might reduce painful emotions involved in investing (Shiv et al. 2005b). This finding could explain this study's lack of emotional connection and investment decision making. ...
Early investors possess unique sets of decision-making characteristics. They are more open to experience and eager to face risks. However, to the best of the authors’ knowledge, the discussions of nascent investors upon making the investment decision and its eroding biases were still elusive. The vital role of emotion as a bias in decision making was also inadequately addressed. This study enhanced behavioral finance knowledge by examining emotion’s role in regulating the illusion of control, overconfidence, and investors’ decision making. In total, 456 initial investors in Indonesia participated in online questionnaires, forming the data for covariance-based structural model analysis. This study found that emotion significantly increased the illusion of control, but not overconfidence or decision making, contrary to the bulk of previous studies. The illusion of control exhibited a substantial significant effect of as much as 86.4% toward overconfidence, followed by a considerable increase in decision making. The results of our study also pointed to the unique chain effects of biases affecting the decision-making process of nascent investors in the emerging market. This finding implied they possessed a unique bias mechanism in constructing their decision.
... The key to being a successful trader is a huge business. While many academics argue that emotions degrade trading performance (Gray, 1999;Lerner and Keltner, 2001;Lo et al., 2005;Lucey and Dowling, 2005;Shiv, et al., 2005;Schunk and Betsch, 2006), there are those who contest that emotions have, instead, a positive impact (Ackert et al., 2003;Ackert and Deaves, 2010). ...
... Whatever the stance on anticipatory emotions, there is agreement that they are important signals integrated into current decision strategies. It is important to note that there appears to be a "dark side" of anticipatory emotion, where high levels of unconscious emotion can degrade choice behaviour (Shiv et al., 2005). Given the case that anticipatory emotions are not comprehensively "good" nor "bad" for investment decisions, what can we learn about the relationship between anticipatory emotion and risk-aversion/−seeking in a range of trading environments? ...
... Our findings that the association between anticipatory emotion and trading performance in context-dependent is supported by Shiv et al. (2005). In this study, patients with damage to the ventromedial frontal cortex, who exhibit blunted anticipatory SCRs, and healthy participants were gifted $20 and given 20 opportunities to invest subsequent $1 portions of that money into a 50/50 gamble between losing $1 or winning $2.50. ...
Increasing financial trading performance is big business. A lingering question within academia and industry concerns whether emotions improve or degrade trading performance. In this study, 30 participants distributed hypothetical wealth between a share (a risk) and the bank (paying a small, sure, gain) within four trading games. Skin Conductance Response was measured while playing the games to measure anticipatory emotion, a covert emotion signal that impacts decision-making. Anticipatory emotion was significantly associated with trading performance but the direction of the correlation was dependent upon the share’s movement. Thus, anticipatory emotion is neither wholly “good” nor “bad” for trading; instead, the relationship is context-dependent. This is one of the first studies exploring the association between anticipatory emotion and trading behaviour using trading games within an experimentally rigorous environment. Our findings elucidate the relationship between anticipatory emotion and financial decision-making and have applications for improving trading performance in novice and expert traders.
... Building upon the model by Barberis, Huang, and Santos (2001), Merkle, Müller-Dethard, and Weber (2020) predict that prior paper gains increase risktaking because potential subsequent losses up to the level of prior gains are not subject to loss aversion. This prediction is consistent with the realization effect (see e.g., Ackert et al., 2006;Cárdenas et al., 2014;Langer & Weber, 2008;Shiv et al., 2005), this evidence is not causal because several other differences may have led to the contrasting results (Imas, 2016). However, direct empirical evidence of the realization effect is scarce (see e.g., Imas, 2016;Merkle et al., 2020;Meyer & Pagel, 2019), and field validation of the theoretical predictions for both gains and losses in a setting with positively skewed lotteries is missing. ...
... Reanalyzing existing empirical evidence, Imas (2016) demonstrates that distinguishing between realized and paper losses reconciles the contradictory findings in the literature. For example, Langer and Weber (2008) and Shiv et al. (2005) both employ the experimental investment game used by Gneezy and Potters (1997). 1 While the participants in Langer and Weber (2008) experienced paper losses and took more risk after a loss, the participants in Shiv et al. (2005) experienced realized losses after each round and took less risk after a loss. Furthermore, the field studies of Coval and Shumway (2005) and Liu et al. (2010) analyze the risk-taking behavior of professional traders after morning losses. ...

We test the realization effect, i.e., that risk-taking is greater after paper outcomes than after realized outcomes, using gambling data from a real casino. During a particular casino visit, customers likely perceive that gains and losses are paper outcomes, whereas leaving the casino realizes the final account balance. Using individual-level slot machine gambling records, we find that risk-taking after both paper losses and paper gains increases within a visit and that this effect is more pronounced for larger outcomes. Conversely, realized losses from earlier visits significantly decrease risk-taking if losses are comparatively large, whereas comparatively small realized losses and realized gains do not alter risk-taking. These results provide important field validation of the realization effect in an environment with positively skewed lotteries.
... With respect to the neural activation, we predicted coordination or competition varying across languages and cognitive load conditions between the dorsal striatum, which is associated with decision making (Korucuoglu et al., 2020;Sharpe et al., 2019;Wimmer et al., 2014), and insula and amygdala (Gorka et al., 2019;Korgaonkar et al., 2019;Shiv et al., 2005), two areas associated with emotion processing. If the automaticity of L1 processing enables more emotional access whereas the increased cognitive demands or task difficulty in L2 leave little room for emotionality, we should find that cognitive load boosts access to emotion in L1 but hinders access to emotion in L2. ...
... Both left amygdala and right insula modulate emotional processing (Gorka et al., 2019;Hassel et al., 2020;Korgaonkar et al., 2019;Shiv et al., 2005;Xue et al., 2011): the former is known to be involved in sympathetic emotional activation (Eimontaite et al., 2019;Korn & Bach, 2019;Orem et al., 2019;Williams et al. 2005), and the latter is associated with negative affect and avoidance behavior (Saga et al., 2019;Turel et al., 2020). Here these regions were found to interact differently with cognitive load depending on the language context. ...
... Thus, we chose left amygdala and right insula as Regions of Interest (ROIs). These areas are known to be associated with emotion processing(Gorka et al., 2019; Korgaonkar et al., 2019;Shiv et al., 2005; Xue et al., 2011;Zhang et al., 2019). Moreover, the ROI followup analyses were corrected for multiple comparisons because we divided both insula and amygdala into left and right hemispheres (all the p values are multiplied by 2, Bonferroni correction). ...
Prior work has reported that foreign language influences decision making by either reducing access to emotion or imposing additional cognitive demands. In this fMRI study, we employed a cross-task design to assess at the neural level whether and how the interaction between cognitive load and emotional involvement is affected by language (native L1 vs. foreign L2). Participants completed a Lexico-semantic task where in each trial they were presented with a neutrally or a negatively valenced word either in L1 or L2, either under cognitive load or not. We manipulated cognitive load by varying the difficulty of the task: to increase cognitive demands, we used traditional characters instead of simplified ones in L1 (Chinese), and words with capital letters instead of lowercase letters in L2 (English). After each trial, participants decided whether to take a risky decision in a gambling game. During the Gamling task, left amygdala and right insula were more activated after having processed a negative word under cognitive load in the Lexico-semantic task. However, this was true for L1 but not for L2. In particular, in L1, cognitive load facilitated rather than hindered access to emotion. Further suggesting that cognitive load can enhance emotional sensitivity in L1 but not in L2, we found that functional connectivity between reward-related striatum and right insula increased under cognitive load only in L1. Overall, results suggest that cognitive load in L1 can favor access to emotion and lead to impulsive decision making, whereas cognitive load in L2 can attenuate access to emotion and lead to more rational decisions.
... Despite these neuroimaging data, we have relatively little causal information regarding the brain regions involved during risky decision-making. Yet, lesions of the medial prefrontal cortex consistently resulted in increased risk-taking and disadvantageous behaviors (Bechara et al., 1994;Bechara et al., 1999;Clark et al., 2008;Sanfey et al., 2003;Shiv et al., 2005;Weller et al., 2007) or no difference from the control group (Leland & Grafman, 2005;Sanfey et al., 2003), whereas lesions of the insula led to both decreased risky choices or increased betting behaviors compared to healthy subjects (Clark et al., 2008;Shiv et al., 2005). These discrepancies between studies and with the fMRI literature may be explained by the scope of the brain lesions, which in some cases extend well beyond the targeted regions, thus reaching adjacent areas that may also contribute to the observed deficits. ...

Full text available at : http://www.theses.fr/2021GRALS043 // Identifying factors whose fluctuations are associated with choice inconsistency is a major issue for rational decision theory. In this thesis, we investigated how brain activity partly explain choice variability during a multi-attribute choice task by taking advantage of the rare opportunity to either directly record intracortical activity in the human brain or to perform intracortical stimulation to probe the causal involvement of key cortical regions. In the first study, we investigated the neuro-computational mechanisms through which mood fluctuations may bias human choice behavior. Intracerebral EEG data were collected in a large group of participants (n = 30), as they performed interleaved quiz and choice tasks. Baseline neural activity preceding choice onset was confronted first to mood level, estimated by a computational model integrating the feedback received in the quiz task, and then with the weighting of option attributes, in a computational model predicting risk attitude in the choice task. Results showed that 1) elevated broadband gamma activity (BGA) in the ventromedial prefrontal cortex (vmPFC) and dorsal anterior insula (daIns) respectively signaled periods of high and low mood, and 2) increased BGA in vmPFC and daIns respectively promoted and tempered risk-taking by overweighting gain versus loss prospects. Thus, incidental feedback induces brain states that correspond to different moods and biases the comparison of safe and risky options. More generally, this first study might explain why people experiencing positive (or negative) outcomes in some part of their lives tend to expect success (or failure) in any other. In the second study, we focused on the neuro-anatomical correlates underlying the effects of visual fixations on multi-attribute choices. Intracerebral EEG data were collected simultaneously with gaze data in a large group of participants (n = 38), as they performed a multi-attribute accept/reject choice task. Results from study 2 showed that 1) gaze-dependent neural activity (BGA) correlated positively with the value of a given attribute when fixated and negatively with the attribute’s value when not fixated in a large brain network, 2) gaze-dependent neural activity in the vmPFC positively predicted subjects’ choices when looking at gains and 3) gaze-dependent neural activity in the aINS negatively predicted subjects’ choices when looking at losses. Thus, our findings specify key neuro-anatomical insights into how gaze pattern interferes with neural activity to bias multi-attribute choices. Lastly, in the third empirical study of this thesis, we investigated the effect of targeted disruption of anterior insular cortex and ventromedial prefrontal cortex on risky choices. The effect of intracranial electrical stimulation (iES) delivered directly to the human cortex at 50 Hz in a group of epileptic patients (n = 13) were examined while the subjects performed a choice task similar to that used in the previous two studies. Results showed a functional dissociation within the anterior insula: iES on the dorsal anterior insula (daIns) increased risky choices whereas iES on the ventral anterior insula (vaIns) promoted safer choices. Conversely, intracranial electrical stimulation on the vmPFC tended to promote risk-taking (as in daIns). These rare cases highlight the potential causal importance of these brain areas during multi-attribute choices involving uncertainty and provide clues for future mechanistic studies of the anatomy and physiology of choices under uncertainty. Overall, this PhD has expanded knowledge of the neurocomputational mechanisms underlying multi-attribute choice by suggesting that dissociable brain systems may be involved in representing the value of appetitive vs. aversive attributes both prior to and during the choice process.
... On the other side, in complex contexts with a higher degree of uncertainty (known as ambiguous tasks), as occurs in industrial contexts, it could not be feasible to follow reasonable procedures, and many decisions must be made relying on our intuition or our experiences (Shiv et al. 2005;Raab and Gigerenzer 2015). Here, cognitive processes, such as working memory, reinforcement learning, and reversal learning (Bechara and Damasio 2005a, b;Dougherty et al. 2005a, b;Starcke and Brand 2012). ...
... In these contexts, given that there would not necessarily be a "best" decision or, if it exists, it can be complicated to find, alternative criteria to rationality are raised. For example, it can be assessed the adaptivity of decisions, the risk taken, or impulsivity (Haselton et al. 2009;Santos and Rosati 2015); but also other aspects focused on the decisional process rather than on the outcome, such as the ability of participants to learn which alternatives are favorable based on the feedback obtained from successive choices (Shiv et al. 2005;Fridberg et al. 2010;Starcke and Brand 2012). New trends in the decision-making field suggest the need to assess the results and the decisional processes to adequately address the complexity of this cognitive ability (Keys and Schwartz 2007;Brugnach et al. 2011). ...
Decision-making involves numerous associated cognitive processes
(memory, attention, learning, motor system) and is responsible for the final behavior of employees. Decision-making can be effective or lead to errors with significant consequences for organizations (economic or human). For this reason, decision-making is currently being studied extensively from different fields and with different approaches. From Psychology, human decision-making has classically been subject to manual or computerized methods from which general conclusions were drawn. However, decision-making is a highly complex process involving numerous subprocesses that increase the mental workload. In this regard, in recent years, numerous algorithms have been developed from computational models that allow different parameters of decision-making to be extracted and that are making it possible to scrutinize the processes underlying decision-making. Thus, based on Bayesian statistics, computational decision-making models can provide more specificity in studying human decision-making through complex and more robust algorithms to explain and predict this process. Therefore, this chapter aims to review the paradigms of
human decision-making assessment (from a classical to a computational perspective) that allow the reader to have a clear and updated view of evaluating human decision-making. Considering that the tasks shown come from laboratory contexts or basic science, practical implications, and guidelines for their use by ergonomists
and mental workload experts in industrial settings will be shown.

This research focuses on inventory management in Peru's container glass products manufacturer. Glass is a packaging option aligned to human safety and planet sustainability. We analyzed its strategic situation aligned to its operational plan. Then, the supply chain strategy develops an inbound raw material and outbound products balance, with the interactions between purchasing, production and sales. The proposed solution optimized the paint flow, reduced its inventory and its related material obsolescence. The stored data existed in the SAP S/4 Hana cloud system, simplifying the project execution from the bottom line to the up line and relating with the company's green line vision. Due to the increasing influence of the information systems and their implementation for specific problems, we presented an MRP, S&OP or IBP dilemma.KeywordsSupply chain managementGlass producerInventory management
... This tacit emotionally laden somatic knowledge mediates the decision-making process covertly "by enhancing attention and working memory related to options for action and future consequences of choices, as well as to bias the process overtly, by qualifying options for actions or outcomes of actions in emotional terms" (Anderson et al. : 1035.

... By contrast, proselfs, due to some deficiencies or inconsistencies in their education, heavily rely on rational effortful reasoning (Emonds et al. 2011) and are only sensitive to external material rewards (Boone et al. 2010). Since Damasio's originating 1994 book, many empirical and/or experimental research studies have been published, some of which are: Bechara et al. 2000;Finucane et al. 2000;Stuss and Alexander 2000;Carter and Smith Pasqualini 2004;Shiv et al. 2005;Ylisaker et al. 2005;Koenigs et al. 2007;Raine 2008;Critchley 2009;Reimann and Bechara 2010;andDamasio et al. 2012.

... Therefore, emotions gain insights into neuroeconomics [44]. However, emotions can also debase decision-making [46,47]. Decisions are influenced by emotions and partially based on the assumption that the decider can predict others' behaviors; empathy plays a role in decisions as well. ...
The coronavirus disease 2019 (COVID-19) pandemic reveals the decision-making challenges faced by communities, governments, and international organizations, globally. Policymakers are much concerned about protecting the population from the deadly virus while lacking reliable information on the virus and its spread mechanisms and the effectiveness of possible measures and their (direct and indirect) health and socioeconomic costs. This review aims to highlight the various balanced policy decision that would combine the best obtainable scientific evidence characteristically provided by expert opinions and modeling studies. This article's main goal is to summarize the main significant progress in the understanding of neuroeconomics of decision-making and discuss the anatomy of decision making in the light of COVID-19 pandemic.
... Study 1A, which used an environment unfavorable to exploration, contributes to an expanding literature documenting situations in which biases help people make better decisions. Kahneman and Lovallo (1993), for example, showed that loss aversion and risk aversion can be beneficial to managers who are overconfident, whereas Shiv et al. (2005) showed that people with damage to emotion-related brain areas made better decisions in an environment in which risk-taking was beneficial. In contrast, as a result of its different payoff structure, Study 1B yields the more conventional result that loss aversion leads to lower payoffs. ...
Many situations involving exploration, such as businesses expanding into new products or locations, expose the explorer to the potential for subjective losses. How does the potential to experience losses during the course of a search affect individuals' appetite for exploration? In three incentivized studies, we manipulate search outcomes by presenting participants either with a gain‐only environment or a gain‐loss environment. The two environments offer objectively identical incentives for exploration: Using a framing manipulation, we decrease gain‐loss payoffs and provide participants an initial endowment to offset the difference. Participants decide how to explore a one‐dimensional space, receiving payoffs based on their location each period. We predict and find that participants are motivated to avoid losses, which increases exploration when they are incurring losses but decreases exploration when they face the potential for losses. We conclude that exploration is driven by hope of potential gains, constrained by fear of potential losses, and motivated by avoidance of experienced losses.
... This shows that psychological factors contribute to the choice of investment type. This statement strengthens the flawed assumption that economists-psychologists put forward in refuting the traditional financial theory (Shiv et al., 2005;Poterba & Samwick, 1997 Their research explains that preference for risk has a relationship with a person's tendency to choose investments. One factor determining the level of courage to invest is determined by how much someone is interested in investing . ...
Investment interest is the desire to invest, which is followed by a lot of information seeking. Everyone, including a lecturer, may be interested in investing in any form, either real assets or financial assets. Investments are made to obtain a benefit in the future. This research aims to determine how a lecturer's behavior in fostering interest in investing in financial assets, especially stocks, considers the factors that influence it. Participants in this study were lecturers in Surabaya who were certified lecturers and were permanent lecturers at public and private universities. This study uses three exogenous latent variables consisting of financial literacy, attitude, and motivation. One endogenous latent variable, namely investment interest and one moderating variable, namely family. Of the five variables used measured by a total of 21 indicators. The participants in this study were 103 participants. The participants in this study were 103 participants. This study indicates that the variables of financial literacy and motivation have a significant influence on the interest in investing in financial assets. This study suggests that financial literacy and inspiration variables have a considerable impact on the interest in investing in financial assets.
... In addition, ACC, one of the neural bases of risk aversion [17], has been highlighted as an important region in emotional processing [78,79], which can modulate amygdala activity [80] and serve as a connection between the limbic system and the prefrontal cortex [81]. Finally, Shiv et al. [82] showed that patients with lesions in regions such as the amygdala or insula, which are closely related to emotions, showed less risk aversion than other patients with injuries in other regions not related to emotions or healthy controls. All this leads us to think that, if certain genes influence the availability of serotonin in the brain and this, in turn, can influence the brain's own activity (in this case, conditioning the capacity for emotional processing and regulation), behaviors such as risk aversion, which depend, at least partially, on this activity, would ultimately be affected. ...
Risk and loss aversion are phenomena with an important influence on decision-making, especially in economic contexts. At present, it remains unclear whether both are related, as well as whether they could have an emotional origin. The objective of this review, following the PRISMA statements, is to find consistencies in the genetic bases of risk and loss aversion with the aim of understanding their nature and shedding light on the above issues. A total of 23 empirical research met the inclusion criteria and were included from PubMed and ScienceDirect. All of them reported genetic measures from human samples and studied risk and loss aversion within an economic framework. The results for risk aversion, although with many limitations, attributed mainly to their heterogeneity and the lack of control in the studies, point to the implication of multiple polymorphisms related to the regulation of the serotonergic and dopaminergic pathways. In general, studies found the highest levels of risk aversion were associated with alleles that are linked to lower (higher) sensitivity or levels of dopamine (serotonin). For loss aversion, the scarcity of results prevents us from drawing clear conclusions, although the limited evidence seems to point in the same direction as for risk aversion. Therefore, it seems that risk aversion could have a stable genetical base which, in turn, is closely linked to emotions, but more research is needed to answer whether this phenomenon is related to loss aversion, as well as if the latter could also have an emotional origin. We also provide recommendations for future studies on genetics and economic behavior.
... Research suggests that business failure can be associated with futureoriented behaviors and learning [69]. At the same time, grief and dysfunction may hinder such processes [64,70] because disengaged business owners are unlikely to invest in the future [71]. As such, business owners considering terminating their ventures may be unwilling to acquire new skills right before the closure, even though the process of owning and terminating a business may have been a learning experience. ...
We theoretically and empirically examine how acquiring new skills and increased financial worries influenced entrepreneurship entry and exit intentions during the pandemic. To that end, we analyze primary individual-level survey data we collected in the aftermath of the COVID-19's first wave in Russia, which has had one of the highest COVID-19 infection rates globally. Our results show that acquiring new skills during the pandemic helped owners keep their existing businesses and encouraged start-ups in sectors other than information technology (IT). For IT start-ups, having previous experience matters more than new skills. While the pandemic-driven financial worries are associated with business closure intentions, they inspire new business start-ups, highlighting the pandemic's creative destruction power. Furthermore, preferences for formal employment and remote work also matter for entrepreneurial intentions. Our findings enhance the understanding of entrepreneurship formation and closure in a time of adversity and suggest that implementing entrepreneurship training and upskilling policies during recurring waves of the COVID-19 pandemic can be an important policy tool for innovative small business development.
... Over time, the myopic investor is expected to gravitate to a lower level of risk". There are also a few studies supporting this conjecture (see, e.g., Shiv et al., 2005 ). The reason we designed the Red uced _ Bet scenario dynamically in terms of risk reduction after negative feedback, i.e., after losses, is to capture this channel as a second potential mechanism. ...
We introduce a training intervention based on a novel tool to mitigate behavior consistent with myopic loss aversion (MLA). We present the results of a large-scale online experiment with 894 student participants. The study featured a two-step debiasing training intervention based on experience sampling and a subsequent elicitation of MLA. We found that participants in the baseline treatment exhibit behavior consistent with MLA, which was not the case for decision makers who underwent the debiasing training intervention. Nonetheless, we found no statistically significant difference-indifference effect of the training intervention on the magnitude of MLA. However, when we focused on the more attentive participants, the magnitude of the difference-indifference effect of the training intervention increased strongly and became statistically significant when controlling for age, gender, education, field of study, investment experience, and risk preferences.
... Translational practices (of behavioral economics frameworks) have been mentioned to be useful to evaluate the dysregulation of reward-oriented behavior . For example, patients with orbitofrontal cortex (OFC) damage have been reported to make poor decisions about day-to-day activities and engage in risk-taking behaviors (Bechara et al., 1994;Shiv et al., 2005;Floden et al., 2008), which may have negative consequences for their wellbeing and overall mental health (Rahman et al., 2001). Therefore, carrying out decision-making paradigms may help licensed therapists to validate the therapy directed toward patients with impulsive-compulsive disorders, such as for example pathological gamblers (frequently reported among individuals with Parkinson's disease, frontotemporal dementia, and Huntington's disease) and compulsive buyers (characterized with impulse control disorder, which co-occurs with depression) (De Marchi et al., 1998;Javor et al., 2013;Kalkhoven et al., 2014). ...

... Emotion also plays a role in the effects of prior outcomes on risk decisions. One study comparing investment decisions of patients with stable focal lesions in brain regions related to emotion, patients with lesions that were unrelated to emotions, and participants without lesions demonstrated that the first group was less affected by the outcome of their decisions (both gains and losses) and consequently earned more money from their investment than participants from the other groups [13]. ...
We present a study (N = 645) investigating how power alters people’s propensity to take investment risks in a changing decision context of gains and losses and the intensity of their reactions to this experience. The results indicate that people in a state of power made more risky investment decisions than the control group regardless of prior gain or loss outcome, whereas people lacking power took less investment risk than the control group, regardless of previous outcomes. Moreover, people with power and those lacking power differed in their reactions to gains and losses, with the former reacting more to gains and the latter to losses.
... Kenny (2010) studied the contribution of negative emotions in investment performance. Prior to this, Shiv et al. (2005)pioneered a study in defining theoretical linkage of negative emotions with investment behaviour and performance. There are literary verifications that investment performance is a theoretical and empirical function of negative emotions of a person (Pham, 2007). ...
The study documented the way forwards to sustain investment performance, and answered that why emotional beasts (e.g. small investors) are irrational in managing their investment performance, in Pakistan stock exchange (PSX). For this, reasons and challenges are identified to give solutions by testing the intervening link of non-cognitive individual differences (NCIDs) of small investors between investor’s personality traits and investment performance. Using multi-stage cluster sampling, the responses of small investors (n = 248) were taken and structural equation modelling (SEM) was used to draw an inference between constructs. Our result traced mediating role of NCIDs between investor’s personality traits and investment performance. The findings extended the notion that small investors are the emotional investors and emotional disparities in the behavior of small investors are making PSX market conditions as slippery. In return to these inconsistencies, PSX is generating lower rate of return and a weak form of investment efficiency, on regular basis. Therefore, this is important to review and revise PSX’ investment mechanism and offer a sustainable and viable business plan for effective PROI acquisition, enhancing investor base by listing the maximum number of new companies, rigorously teaching and training small investors and updating databases accordingly. Our recommendations would be helpful to uplift the confidence in small investors’, depth in PSX asset base, market efficiency and rational trading. By achieving these proponents in PSX highly guarantees a strong investment performance and to turn the horde of such emotional beasts into a team of rational investors.
... Although much of the research on investment decisions has focused on company-level investments (Graham & Kristina, 2008;Srinivasan et al., 2005), there is also limited research in the marketing field on consumers' investment decisions (e.g., Lim et al., 2020;Mrkva et al., 2021). Research in this area suggests that risk aversion is an important factor that influences financial and investment decisions (Lim et al., 2020;Shiv et al., 2005;Zhou & Pham, 2004). Risk aversion is a function of reference points (Kwon & Lee, 2009) and the extent of sunk costs (Zeelenberg & Van Dijk, 1997). ...
Past research indicates that individuals with scarce resources focus on urgent needs. We hypothesize and find that individuals with scarce financial resources have greater discretionary expenditures such that they engage in more discretionary spending, borrowing, and investing. We demonstrate that one possible explanation for why those with scarce financial resources have greater discretionary expenditures is because they have more optimistic future perceptions. We support our predictions using a sample of over 60,000 observations from a survey in rural India, two archival datasets from surveys in Italy and Germany, and two preregistered online experiments. We control, test, and rule out different alternative explanations. The results of this research extend the findings in the financial scarcity and discretionary consumption literature. Additionally, we provide actionable guidelines for managers and public policy makers on how to nudge individuals with financial scarcity.
... On laboratory tasks of decision-making under risk, insensitivity to differences in expected value between choice options (Weller et al., 2009) and impaired adjustment of betting choices to the odds of winning (Clark et al., 2008) were observed. Another study (Shiv et al., 2005) found reduced loss aversion on an investment task in patients with insula damage. Finally, Clark et al. (2014) showed that insula lesion patients are less susceptible to cognitive distortions during gambling. ...
Humans resist unequal distributions of goods in their social interactions, even if it requires foregoing personal gains. Functional neuroimaging studies implicate the insula in this aversion to social inequity and in fairness-related decisions, but a causal contribution has not yet been established. We compared the responses of 30 patients with lesions to the insula on a multiple-trial version of the one-shot Ultimatum Game, a neuroeconomic social exchange paradigm where a sum of money is split between two players, to those of 30 matched patients with brain injuries sparing the insula. Insula lesion patients accepted offers of an unequal disadvantageous split significantly more often than comparison lesion patients. Computational modeling confirmed that this difference in choice behavior was due to decreased aversion to disadvantageous inequity following insula damage, rather than due to increased decision noise or non-consideration of inequity. Our results provide novel evidence that the insula is causally involved in aversion to inequity and in value-based choices in the context of social interactions.
... Iowa gambling task (IGT) is most frequently employed to assess PD patients' decision-making abilities [81]. In addition to IGT, other tasks that are used are, game of dice task [82], investment task [83], two-choice gambling task [84]. These tasks can be categorized into two paradigms of decision-making under uncertainty and decision-making under risk. ...
Neurodegenerative diseases such as Parkinson’s Disease (PD) and Alzheimer’s Disease severely impact patients and make their day-to-day life activities difficult. We still lack accurate diagnostic measures that can correctly assess the disease condition and its severity. Our study aims to bridge the gap between the predominantly subjective evaluation criterion towards a more enhanced technology-driven evaluation system that gives an accurate indication of the disease progression and helps decide on the optimized therapeutic intervention. In the subsequent sections, we briefly highlight the current evaluation criteria such as MDS-UPDRS and discuss how a quantitatively driven assessment approach would be useful. This study also touches upon assessing different symptoms, different stages of the disease, and classifying the patients. This study tries to cover assessment techniques for the early stage non-motor and motor symptoms, the cardinal symptoms of PD, and also explores the impact of PD on cognitive abilities. We have also briefly touched upon various therapeutic strategies and tried to review a few of the modeling approaches that we believe would go a long way in fine-tuning the disease management of PD itself. PD has a wide range of symptoms, and due to overlapping similarities with other diseases, it becomes incredibly challenging to classify the patients and design therapeutic regimes. We are optimistic that with a combination of experimental and modeling studies, we would be able to bridge this gap.
... Translational practices (of behavioral economics frameworks) have been mentioned to be useful to evaluate the dysregulation of reward-oriented behavior . For example, patients with orbitofrontal cortex (OFC) damage have been reported to make poor decisions about day-to-day activities and engage in risk-taking behaviors (Bechara et al., 1994;Shiv et al., 2005;Floden et al., 2008), which may have negative consequences for their wellbeing and overall mental health (Rahman et al., 2001). Therefore, carrying out decision-making paradigms may help licensed therapists to validate the therapy directed toward patients with impulsive-compulsive disorders, such as for example pathological gamblers (frequently reported among individuals with Parkinson's disease, frontotemporal dementia, and Huntington's disease) and compulsive buyers (characterized with impulse control disorder, which co-occurs with depression) (De Marchi et al., 1998;Javor et al., 2013;Kalkhoven et al., 2014). ...
In the field of psychology, the merge of decision-theory and neuroscientific methods produces an array of scientifically recognized paradigms. For example, by exploring consumer’s eye-movement behavior, researchers aim to deepen the understanding of how patterns of retinal activation are being meaningfully transformed into visual experiences and connected with specific reactions (e.g., purchase). Notably, eye-movements provide knowledge of one’s homeostatic balance and gatekeep information that shape decisions. Hence, vision science investigates the quality of observed environments determined under various experimental conditions. Moreover, it answers questions on how human process visual stimuli and use gained information for a successful strategy to achieve certain goals. While capturing cognitive states with the support of the eye-trackers progresses at a relatively fast pace in decision-making research, measuring the visual performance of real-life tasks, which require complex cognitive skills, is tentatively translated into clinical experiments. Nevertheless, the potential of the human eye as a highly valuable source of biomarkers has been underlined. In this article, we aim to draw readers attention to decision-making experimental paradigms supported with eye-tracking technology among clinical populations. Such interdisciplinary approach may become an important component that will (i) help in objectively illustrating patient’s models of beliefs and values, (ii) support clinical interventions, and (iii) contribute to health services. It is possible that shortly, eye-movement data from decision-making experiments will grant the scientific community a greater understanding of mechanisms underlining mental states and consumption practices that medical professionals consider as obsessions, disorders or addiction.
... Argyris (1991) earlier argued that this approach allows stakeholders to 'learn how to learn' for deeper problem-solving and continuous improvement. The descriptive used by Gregory et al. (2012), 'how people actually take decisions', is largely based on a priori ideas and perceptions, existing narratives, mental models, openness to change, estimations in time and space, as well as an individual's values, motivations and passions, comfort with types of risk, level of self-awareness and self-confidence, and emotional and physical well-being (Shiv et al. 2005;Slovic 2004;Malakooti 2012;Danzigera et al. 2011). Baratan (2007) promotes a cognitive perspective on decision-making in which constructive discourse can serve to modify individual perspective and influence collective perspectives. ...
Successfully achieving the sustainable development goals requires addressing complex, interrelated, wicked problems across multiple scales and contexts and decision-making that tackles nested layers of goals and targets across the interrelated social, economic and environmental dimensions of sustainability. The Stakeholder Approach to Risk-informed and Evidence-based Decision-making (SHARED) bridges processes, tools and accessible evidence to support inter-sectoral and multi-stakeholder decision-making and implementation aimed at achieving resilience aspirations and associated investments. Adaptive collaborative management and multiple-loop learning serve as a basis for the systematic approach to institutional learning that supports shifts in underlying institutional understanding and values leading to actionable organisational change. This paper describes a contextual application of tailored technical assistance and institutional support to the Turkana County Government in Kenya, a newly devolved governance structure, under conditions of complexity. The SHARED Turkana County decision case demonstrates how the approach responded to a policy aspiration, resulting in greater and more intentional use of evidence in planning and budget allocations, cross-sectoral and multi-stakeholder partnerships, inclusive and transformative projects and a consultative and evidence-based five-year County Integrated Development Plan.
... The zones that were found to be related to moral decisions were those that connected the limbic brain, which is associated with emotional processing, and the Pre-Frontal Cortex (PFC), which is associated with rational decision-making. Recent investigations that correlate decision-making in moral dilemmas with neural images show that when these zones or circuits connected with them are damaged, people have difficulty making moral decisions (Cuñat-Agut, Martí-Vilar, & Suay, 2016;Shiv, Loewenstein, Bechara, Damasio, & Damasio, 2005). These findings show that emotions are closely involved in moral decision making. ...
Moral reasoning is a field of investigation that has been raising more and more interest. It is necessary to have valid tools for evaluating moral reasoning. To this end, this article provides an update review about existing tools that evaluate moral reasoning, focusing on the description of their characteristics as well as their psychometric properties. In a literature review using the Web of Science, the scientific literature was reviewed between 1900 and 2017, focusing on the last 30 years. Three search processes were performed: an initial one to observe the current situation, a system applying inclusion-exclusion criteria, and a manual search to evaluate the obtained results. A total of 21 instruments were found that evaluate moral reasoning. Possible aspects of improvement in lines of future research are discussed.
... Gefühlskälte oder Angstfreiheit unter gewissen Umständen produktiv für Unternehmen sein. Wenngleich Emotionen im Alltag eine überaus wichtige Rolle beim Verständnis von sozialen Interaktionen einnehmen, sind diese im ökonomischen Kontext nicht immer funktional und zielführend: So konnte beispielsweise in einer Studie von Shiv et al. (2005) gezeigt werden, dass sich spezifische Emotionen bei gesunden Versuchspersonen negativ auf ihre Investitionsentscheidungen auswirken können. Demgegenüber trafen in der Studie Versuchspersonen mit Hirnläsionen, die Emotionszentren betrafen, die rationalsten und die in diesem Versuchsparadigma somit auch rentabelsten Entscheidungen. ...
... The dysfunctional version of this behavior could be constituted by autistic behaviors, predominantly driven by rationality with an insensitivity towards emotions (Camerer et al., 2004;Riccardi et al., 2015). This suggests that different situations and frames may influence decision-making so that in certain domains of life, like the financial markets, where individuals mainly opt for being risk-averse, people with psychopathic traits and with a lack of emotion could be more suitable in situations where risk-taking is the rational thing to do and a deficiency in somatic markers can be helpful (Shiv et al., 2005;Sobhani et al., 2011). ...
Within the neuroeconomics field, there are two evident situations in which decisionmaking process do not respect the rule of expected utility: gambling and moral behaviors. In the case of gambling behavior, a tendency to engage in risky decision-making could lead to choose disadvantageous options (loss vs gain) and long-term negative economic consequences. Regarding moral behavior, subjects prefer options not always related to their expected utility, but more to their social and ethical significance (fair vs unfair). This commentary discusses both the theoretical and empirical basis of these behaviors, focusing on neurophysiological methods adopted to investigate commonalities and differences in physiological and behavioral subjects’ responses. The dichotomy between emotions and rationality will be explored considering two popular economics games, Iowa Gambling Task and Ultimatum Game, and will be discussed in the light of somatic marker hypothesis frame. We propose a multidimensional approach to describe more in-depth real-world decision-making situations in neuroeconomics.
... Experiments show that patients with lesions in "emotional regions" of the brain (e.g. amygdala) tend to be substantially less loss averse than control groups (Shiv et al., 2005;De Martino et al., 2010). Neural imaging studies provide further evidence that asymmetric reaction to gains and losses indeed has a neural basis (Tom et al., 2007). ...
Background: Tendency to addiction as a social problem has various causes, which personality traits (psychological factor) and resilience (protective factor) are among the individual factors that play a role in the tendency to addiction. But research examining the propensity for addiction, horned personality traits, and resilience in a structural model has not yet been conducted.
Aims: The aim of this study was to investigate the structural relationships between Horney's personality dimensions and resilience with addiction tendencies.
Methods: The present study was a descriptive correlation and structural equation. The statistical population of the students of Tehran Azad University in the academic year 1399-1400, 387 people were selected by convenience sampling method and three-dimensional questionnaires of Horney-Kolich (2012), Connor-Davidson (2003) and Iranian Drug Addiction Readiness Scale (Zargar et al., 2008) responded. The obtained data were analyzed by Pearson correlation coefficient and path analysis.
Results: The results showed that the dimensions of obedient, aggressive, and distant personality and resilience with standard coefficients of 0.284, 0.324, 0.320, and -0.611, respectively, had a significant positive and negative effect on the tendency to consume substances. Also, resilience does not play a mediating role in the relationship between Horney's personality dimensions and addiction tendencies. Therefore, the hypothetical model was modified and the final model of the research was approved using fitness indicators.
Conclusion: Therefore, it can be said that personality traits play a role in addiction tendency and may be effective in developing preventive interventions for addiction tendency.
Traditional Word-of-Mouth (WOM) literature shows that emotions embedded in advertising appeals or referrals/reviews influence consumer buying journey. However, there is a paucity of research exploring the distribution and impact of emotional content in “online” consumer reviews (OCRs). Hence, in this study, an attempt is made to examine the emotional content in OCRs and to study the influence of discrete positive and negative emotions on the perceived OCR helpfulness, by classifying them based on their valence and arousal. Further, the impact of the inconsistency between the star rating of a review and the qualitative review-related factors (i.e. emotions and valence) is analyzed. This study uses Natural Language Processing (NLP) and text-mining techniques to retrieve valence and emotions from 100,000 reviews from Yelp.com and employs model testing methods to verify the hypotheses. The results reveal that: (1) both qualitative/latent (emotions and valence) and quantitative/manifest review message factors (star ratings, word count) are important in determining the OCR helpfulness; (2) the difference in arousal (high/low) and valence (positive/negative) has a differential impact on OCR helpfulness; (3) within high-arousal emotions, negative-valence emotions influence OCR helpfulness more than positive-valence emotions; and (4) consumers’ perceptions of OCR helpfulness depends on the consistency between the qualitative and quantitative content factors.
Richard H. Thaler is considered by many as responsible for the genesis of modern behavioural economics. His work highlighted violations of standard assumptions of economic theory and ultimately led to a monumental shift in economic analysis. Thaler showed that systematic deviations from the predictions of normative theory are not only prevalent but also have a significant impact on behaviour in a variety of market settings. His work has spawned multiple literatures in economics, marketing, and public policy, and launched the subfield of behavioural finance. This chapter attempts to capture his legacy by delineating his journey from graduate school to being awarded the 2017 Nobel Memorial Prize in Economic Science.KeywordsRichard ThalerBehavioural economicsMental accountingBehavioural finance

Introduction
This paper reports a time series analysis of day-to-day emotional text related to fund investments on Weibo (Sina Corporation, Beijing, China).
Methods
The present study employed web-crawler and text mining techniques through Python to obtain data from January 1, 2021 to December 31, 2021.
Results
Using an auto-regressive integrated moving average model and vector auto-regressive model, the results indicated that fund performance was a significant predictor of fear, anger, and surprise expressions on Weibo. A relationship among emotions within a certain single fund was not found, but textual emotions could be predicted by ARIMA models within emotions.
Discussion
The findings provide insight for media emotion analysis combining linguistic and temporal dimensions in both the communication and psychology disciplines.
Emotional facial expressions are ubiquitous and potent social stimuli that can signal favorable and unfavorable conditions. Previous research demonstrates that emotional expressions influence preference judgments, basic approach-avoidance behaviors, and reward learning. We examined whether emotional expressions can influence decisions such as choices between gambles. Based on theories of affective cue processing, we predicted greater risk taking after positive than negative expressions. This hypothesis was tested in four experiments across tasks that varied in implementation of risks, payoffs, probabilities, and temporal decision requirements. Facial expressions were presented unobtrusively and were uninformative about the choice. In all experiments, the likelihood of a risky choice was greater after exposure to positive versus neutral or negative expressions. Similar effects on risky choice occurred after presentation of different negative expressions (e.g., anger, fear, sadness, and disgust), suggesting involvement of general positive and negative affect systems. These results suggest that incidental emotional cues exert a valence-specific influence of on decisions, which could shape risk-taking behavior in social situations.
This chapter discusses the rational investor, behavioral finance, neurofinance, consensus opinions, and their impacts on stock and other markets. The chapter begins with a discussion of rational investor paradigms, describing the St. Petersburg Paradox and von Neuman-Morgenstern axioms of choice. Essential findings of Prospect Theory are described, including the framing and anchoring problems, myopia, overreaction, overconfidence, and other fundamental problems in pursuing sound rational solutions to investing, and trading problems. Connections between all of these barriers to rational decision-making to finance are explored. Psychological and physiological underpinnings to such problems are offered. Relationships between irrational investors and markets, either efficient or inefficient are discussed. In this discussion, game shows, betting markets, analyst estimates, and consensus forecasts are offered as evidence that cognitively impaired investors can comprise rational markets, while information cascades and herding can lead to irrational markets.
Procrastination refers to an irrationally delay for intended courses of action despite of anticipating a negative consequence due to this delay. Previous studies tried to reveal the neural substrates of procrastination in terms of connectome-based biomarkers. Based on this, we proposed a unified triple brain network model for procrastination and pinpointed out what challenges we are facing in understanding neural mechanism of procrastination. Specifically, based on neuroanatomical features, the unified triple brain network model proposed that connectome-based underpinning of procrastination could be ascribed to the abnormalities of self-control network (i.e., dorsolateral prefrontal cortex, DLPFC), emotion-regulation network (i.e., orbital frontal cortex, OFC), and episodic prospection network (i.e., para-hippocampus cortex, PHC). Moreover, based on the brain functional features, procrastination had been attributed to disruptive neural circuits on FPN (frontoparietal network)-SCN (subcortical network) and FPN-SAN (salience network), which led us to hypothesize the crucial roles of interplay between these networks on procrastination in unified triple brain network model. Despite of these findings, poor interpretability and computational model limited further understanding for procrastination from theoretical and neural perspectives. On balance, the current study provided an overview to show current progress on the connectome-based biomarkers for procrastination, and proposed the integrative neurocognitive model of procrastination.
Özet: Nöroekonomi, ekonomik kararların sinirsel temellerini belirlemek amacıyla nörobilimsel ölçü araçlarını kullanan disiplinler arası bir alan olarak kabul edilmektedir. Bu çalışmada ekonomik karar verme mekanizması nörobilim açısından incelenmektedir. Rasyonel kararların beynin mantık kısmında alınıp alınmadığı, risk ve belirsizlik ortamında verilen kararların beynin hangi kısımlarını harekete geçirdiği yapılan deneyler çerçevesinde analiz edilmektedir. İlk olarak beynin işlevleri ve iktisadi karar verme süreci üzerindeki etkisi ele alınmaktadır. İkinci olarak, ekonomi teorisinde risk ve belirsizlik altında karar verme sürecini inceleyen "beklenen fayda teorisi"nin anomalileri ve bu anomalileri ortaya çıkaran deneylerin sonuçlarına yer verilmektedir. Son olarak, risk ve belirsizlik altında karar verme süreci nöroekonomi çerçevesinde deneysel örneklerle incelenmektedir. Çalışmanın amacı, karar verme sürecinde duyguların güçlü bir etkiye sahip olup olmadığını ortaya koymaktır. Tüm yapılan deneylerde insanların kararlarında sistematik hatalar yaptığı, risk ve belirsizlik altında beynin evrimsel olarak daha yaşlı kısmının harekete geçtiği bulgularına ulaşılmıştır. Sonuçlar belirsizlikten kaçınma için herhangi bir özel açıklamayı açıkça desteklemese de, açık olan şu ki; insanlar belirsizliğe karşı anında olumsuz bir duygusal tepki vermektedirler.
Abstract: Neuroeconomics is an interdisciplinary field that uses neuroscientific measurement tools to determine the neural basis of economic decisions. In this study, economic decision making mechanism is examined in terms of neuroscience. Many experiments have been conducted on whether rational decisions are made in the logic part of the brain, and which parts of the brain are activated by decisions made in an environment of risk and uncertainty. In this study, analysis is made within the framework of these experiments. First, the functions of the brain and its effect on the economic decision-making process are discussed. Secondly, the anomalies of the "expected utility theory" that examines the decision-making process under risk and uncertainty in economic theory and the results of the experiments that reveal these anomalies are included. Finally, the decision-making process under risk and uncertainty is examined with empirical examples within the framework of neuroeconomics. The aim of the study is to reveal whether emotions have a strong influence in the decision-making process. In all experiments, it has been found that humans make systematic mistakes in their decisions, and that the evolutionarily older part of the brain is activated under risk and uncertainty. While the results do not explicitly support any specific explanation for uncertainty avoidance, what is clear is that people have an immediate negative emotional response to uncertainty.
We analyze how individuals reinvest realized capital gains and losses exploiting plausibly exogenous sales due to mutual fund liquidations. Individuals reinvest 83% if a forced sale results in a gain relative to the initial investment; but reinvest only 40% in the event of a loss. This difference is statistically significant for more than six months and arises because many individuals forced to realize a loss choose not to reinvest anything and some even exit the stock market altogether. Individuals treat realized losses differently from paper losses and are discouraged from investing more and participating in the stock market. This article is protected by copyright.

La principal aportación de esta investigación se encuentra en la preferencia por productos ecológicos versus los contaminantes después de presentar su precio para tomar una decisión al momento de comprar, que es el punto central de este estudio. La evidencia encontrada demuestra que, ante una elección que incluye beneficios al medio ambiente, las personas en su primera elección durante sus compras (que podrían ser las que efectúan cotidianamente cada que compran), no necesariamente se deciden por los beneficios ambientales; al contrario, optan por productos que tienen consecuencias al medio ambiente. Sin embargo, la sensibilidad al precio y el umbral de comparación de precios bajos frente a precios altos, incide directamente en el cambio en su preferencia por productos ecológicos, con un menor precio y por consiguiente un bajo costo en sus finanzas personales.
This paper puts forth the foundation for a different type of negotiation that reflects in a more realistic way the behavior of human beings when making complex decisions, aligned with the cognitive process involved. The positive and the negative aspects of decisions reflect two components in the human brain: the nucleus accumbens and the amygdala. The first component deals with behavior related to rewards or potential gains, and the other with behavior related to risk aversion or potential losses. Negotiations require communication, learning, accommodation of positions, and development of alternatives and modification of constraints. Negotiation support systems help and advice negotiators; structure and analyze the problem; elicit preferences to construct a preference function; visualize different aspects of the problem and the process; and facilitate communication and learning. The methodology used is based on the Analytic Hierarchy Process previously employed in a retributive conflict in which each party calculates the incremental benefits it gets and the costs to its opponent. The Israeli–Palestinian conflict is used to show the viability of the approach and the type of inputs we need to study conflicts with this approach. The negotiation platform that we describe here help the actors to start and engage a negotiation from noncooperative parties. It can also be used in human– negotiations to expedite reaching an agreement if one exists. However, we are not seeking automated negotiations. Advantages and risks of Artificial Intelligence contribution in negotiation support systems for cognitive and retributive conflict resolution based on AHP (CRCR‐AHP) are also discussed.

Given the emergence of sustainability as the defining issue of our time, it is essential for university graduates, and especially business and economics students, to have a fundamental grasp of the key issues in this emerging multidisciplinary field of study. Nemetz provides a comprehensive, detailed overview of the interlinked economic and ecological concepts central to this new discipline. Accompanying the introduction of the underlying theory is a broad array of real-world supporting data from Asia, Europe and North America. This volume also features a chapter on the threat of emerging pandemics and their significance for the achievement of a truly sustainable world. This book accentuates the value and importance of a strong sustainability approach in an age of climate change emergency. It is an ideal companion for instructors and students of sustainability in business, economics and related disciplines such as geography and political science.
Research demonstrates that people utilize both reasoning and feeling in decision making and that both strategies can be advantageous. However, little is known about how people perceive their decision making relative to others. Despite research findings and popular appeals supporting the use of affective decision processes, across a series of studies, we find that individuals believe they rely more on reasoning, and less on feelings, than others. These effects are driven by the motivation to self‐enhance where, in most contexts, individuals believe the use of reasoning is superior, and self‐enhancing, compared to the use of feelings. Consistent with this mechanism, beliefs that one’s decisions are more rational than others’ are: (a) stronger for those who exhibit greater beliefs in the superiority of reasoning (vs. feeling), (b) attenuated when the decision context precludes motivational thinking about the self or the self is affirmed, and (c) reversed when the use of feelings is perceived as more self‐enhancing. We demonstrate downstream consequences (e.g., decision delegation), rule out alternative explanations, and discuss practical implications of these lay beliefs.
This experimental study addresses the question of whether positive and negative emotions have an influence on diversification behaviour, and it reveals that only a small part of subjects take rational decisions and always choose the optimal portfolio. In addition, the study shows that the mood of subjects has an influence on their portfolio decisions and thus also on their exposure to risk. The average risk of the portfolio - measured against the standard deviation of the returns - is lower in the treatment entitled ‘neutral’ than in the treatments entitled ‘positive’ and ‘negative’.
Human decisions are susceptible to biases, but establishing causal roles of brain areas has proved to be difficult. Here we studied decision biases in 17 people with unilateral medial prefrontal cortex damage and a rare patient with bilateral ventromedial prefrontal cortex (vmPFC) lesions. Participants learned to choose which of two options was most likely to win, and then bet money on the outcome. Thus, good performance required not only selecting the best option, but also the amount to bet. Healthy people were biased by their previous bet, as well as by the unchosen option’s value. Unilateral medial prefrontal lesions reduced these biases, leading to more rational decisions. Bilateral vmPFC lesions resulted in more strategic betting, again with less bias from the previous trial, paradoxically improving performance overall. Together, the results suggest that vmPFC normally imposes contextual biases, which in healthy people may actually be suboptimal in some situations.
In the conditions of increasing demand barrier, the enterprise's basic capital is customers. From an enterprise point of view, this means the need to create a dual perceived and defined customer value which remains related to market value (income and development potential) and customer resource value (reference, information and cooperative potential). The progressing digitisation process transfers business processes, and thus relationships, into virtual space. We identify customers consumers’ behaviour in virtual space and the goals they connect with participation in relational networks.
We believe that the use of the potential of the virtual space in which the customer moves is determined by the awareness of the potential of the web, which is related to its readiness and ability to use it. This factor determining customer value (customer equity) exerts and will exert a significant impact on the process of creating value for the customer in the future, strengthening its position as a partner in the process of creating value.
• Women are increasingly seen as active agents of change, the dynamic promoters of social transformations that can alter lives of both women and men. – Amarty Sen (Renowned Economist from India). The origin of the Indian idea of appropriate female Behaviour is described by Manu in 200 BC: as “by a young girl, by a young woman, or even by an aged one, nothing must be done independent, even in her own house”. Their role typically restricted only for cooking, childcare, laundry, cleaning and the collection of water, fuel and wood. Women are continued to be excluded in social, economic and political domains. In settings where socio cultural norms restrict women’s mobility, their interactions with members of the opposite sex and their ability to attend trainings or receive formal education, women’s access to information, institutions and markets is compromised. Despite this, major changes have occurred in the status of women in India. Today’s women are outpacing men in several areas and have high offices including that of the president, Prime Minister, Chief Ministers and Governors of the states. Surprisingly investing is one such area which still proves gender gap between men and women. However, few studies have been carried out on gender differences in investment behaviour and women investment behaviour, it was evidenced from those studies that women are more risk averse than men. This study is an attempt to understand the psychology of Indian women towards Risk –Return characteristics of various investment avenues. For the purpose of study 480 Women investors have been surveyed and comprehensive view on their perspectives towards risk – return characteristics have been presented in this paper.
Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at a decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfields of psychology, they show that emotional reactions to risky situations often diverge from cognitive assessments of those risks. When such divergence occurs, emotional reactions often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive-consequentialist terms.
In this article the authors develop a descriptive theory of choice using anticipated emotions. People are assumed to anticipate how they will feel about the outcomes of decisions and use their predictions to guide choice. The authors measure the pleasure associated with monetary outcomes of gambles and offer an account of judged pleasure called decision affect theory. Then they propose a theory of choices between gambles based on anticipated pleasure. People are assumed to choose the option with greater subjective expected pleasure. Similarities and differences between subjective expected pleasure theory and subjective expected utility theory are discussed.
The equity premium puzzle refers to the empirical fact that stocks have outperformed bonds over the last century by a surprisingly
large margin. We offer a new explanation based on two behavioral concepts. First, investors are assumed to be “loss averse,”
meaning that they are distinctly more sensitive to losses than to gains. Second, even long-term investors are assumed to evaluate
their portfolios frequently. We dub this combination “myopic loss aversion.” Using simulations, we find that the size of the
equity premium is consistent with the previously estimated parameters of prospect theory if investors evaluate their portfolios
annually.
We used a novel computerized decision-making task to compare the decision-making behavior of chronic amphetamine abusers, chronic opiate abusers, and patients with focal lesions of orbital prefrontal cortex (PFC) or dorsolateral/medial PFC. We also assessed the effects of reducing central 5-hydroxytryptamine (5-HT) activity using a tryptophan-depleting amino acid drink in normal volunteers. Chronic amphetamine abusers showed suboptimal decisions (correlated with years of abuse), and deliberated for significantly longer before making their choices. The opiate abusers exhibited only the second of these behavioral changes. Importantly, both sub-optimal choices and increased deliberation times were evident in the patients with damage to orbitofrontal PFC but not other sectors of PFC. Qualitatively, the performance of the subjects with lowered plasma tryptophan was similar to that associated with amphetamine abuse, consistent with recent reports of depleted 5-HT in the orbital regions of PFC of methamphetamine abusers. Overall, these data suggest that chronic amphetamine abusers show similar decision-making deficits to those seen after focal damage to orbitofrontal PFC. These deficits may reflect altered neuromodulation of the orbitofrontal PFC and interconnected limbic-striatal systems by both the ascending 5-HT and mesocortical dopamine (DA) projections.
The authors present an overview of the neural bases of emotion. They underscore the role of the prefrontal cortex (PFC) and amygdala in 2 broad approach- and withdrawal-related emotion systems. Components and measures of affective style are identified. Emphasis is given to affective chronometry and a role for the PFC in this process is proposed. Plasticity in the central circuitry of emotion is considered, and implications of data showing experience-induced changes in the hippocampus for understanding psychopathology and stress-related symptoms are discussed. Two key forms of affective plasticity are described--context and regulation. A role for the hippocampus in context-dependent normal and dysfunctional emotional responding is proposed. Finally, implications of these data for understanding the impact on neural circuitry of interventions to promote positive affect and on mechanisms that govern health and disease are considered.
Emotion is central to the quality and range of everyday human experience. The neurobiological substrates of human emotion
are now attracting increasing interest within the neurosciences motivated, to a considerable extent, by advances in functional
neuroimaging techniques. An emerging theme is the question of how emotion interacts with and influences other domains of cognition,
in particular attention, memory, and reasoning. The psychological consequences and mechanisms underlying the emotional modulation
of cognition provide the focus of this article.
Economics can be distinguished from other social sciences by the belief that most (all?) behavior can be explained by assuming that rational agents with stable, well-defined preferences interact in markets that (eventually) clear. An empirical result qualifies as an anomaly if it is difficult to "rationalize" or if implausible assumptions are necessary to explain it within the paradigm.

Given the environmental concerns of our planet, it is imperative to consider issues of environmental sustainability. Researchers argue that the most serious environmental problems are not merely issues of science, but that of individual behavior. Solutions, therefore, must consider the role of the individual—how one can change his/her behaviors to be more environmentally conscious. The experience of negative or positive emotions, may impact not only people’s experiences with the environment, but also their tendency to engage in pro-environmental behavior. The present study sought to experimentally investigate the role of emotion and information on pro-environmental behavior change. Results indicate that neither emotion nor information was found to influence pro-environmental behavior change. The study confirms, however, the importance of pro-environmental attitudes on predicting behavioral intentions, and current pro-environmental behaviors as a necessary predictor of pro-environmental behavior change. Just as old behavior patterns are identified as barriers to pro-environmental behaviors, the opposite is also true: individuals who already engage in a number of pro-environmental behaviors are most likely to adopt new behaviors to reduce their ecological footprint and increase their sustainability efforts.

Affective processes were predicted to play a critical role in choices among complex stimuli. As hypothesized, self-report measures of individual differences in affective information processing were associated with choices in a task designed by Bechara, Damasio, Damasio, and Anderson (1994) to mimic the gains, losses, and uncertainties of real life decisions. The results were stronger when the processing of losses was considered separately from the processing of gains. Greater negative affectivity was associated with more avoidance of high-loss options; greater positive affectivity was associated with more choices from high-gain options. Both measures of affectivity added unique explanatory power to the prediction of choices among the decks over and above conscious knowledge about the decks. Affect appears to play an important role in guiding decisions and judgments.
Abnormal decision making is a central feature of neuropsychiatric disorders. Recent investigations of the neural substrates underlying decision making have involved qualitative assessment of the cognition of decision making in clinical lesion studies (in patients with frontal lobe dementia) and neuropsychiatric disorders such as mania, substance abuse and personality disorders. A neural network involving the orbitofrontal cortex, ventral striatum and modulatory ascending neurotransmitter systems has been identified as having a fundamental role in decision making and in the neural basis of neuropsychiatric diseases. This network accounts for the dissociations among decision-making deficits in different clinical populations. Ultimately, a more refined and sophisticated characterization of such deficits might guide the early diagnosis and cognitive and therapeutic rehabilitation of these patients.
Cognitive deficits associated with the chronic abuse of drugs have important theoretical and clinical significance: such deficits reflect changes to the underlying cortical, sub-cortical and neuromodulatory mechanisms that underpin cognition, and also interfere directly with rehabilitative programs. Recent investigations have been made into the neuropsychology of chronic abuse of cannabis, stimulants and opiates. It is suggested that future progress in this area, involving developing advances in brain-imaging and neuropharmacology, will capitalize on experimental demonstrations of specific patterns of impairments in decision-making, attention and memory function.
Initial explorations in the burgeoning field of neuroeconomics have highlighted evidence supporting a potential dissociation between a fast automatic system and a slow deliberative controlled system. Growing research in the role of emotion in decision-making has attempted to draw parallels to the automatic system. This chapter will discuss a theoretical framework for understanding the role of emotion in decision-making and evidence supporting the underlying neural substrates.
This chapter applies a conceptual framework to understanding the role of emotion in decision-making, and emphasizes a distinction between expected and immediate emotions. Expected emotions refer to anticipated emotional states associated with a given decision that are never actually experienced. Immediate emotions, however, are experienced at the time of decision, and either can occur in response to a particular decision or merely as a result of a transitory fluctuation. This chapter will review research from the neuroeconomics literature that supports a neural dissociation between these two classes of emotion and also discuss a few interpretive caveats.
Several lines of research including regret, uncertainty, social decision-making, and moral decision-making have yielded evidence consistent with our formulization--expected and immediate emotions may invoke dissociable neural systems.
This chapter provides a more specific conceptualization of the mediating role of emotions in the decision-making process, which has important implications for understanding the interacting neural systems underlying the interface between emotion and cognition--a topic of immediate value to anyone investigating topics within the context of social-cognitive-affective-neuroscience.
Does the period over which individuals evaluate outcomes influence their investment in risky assets? Results from this study
show that the more frequently returns are evaluated, the more risk averse investors will be. The results are in line with
the behavioral hypothesis of “myopic loss aversion,” which assumes that people are myopic in evaluating outcomes over time,
and are more sensitive to losses than to gains. The results have relevance for the equity premium puzzle, and also for the
marketing strategies of fund managers.
Deciding advantageously in a complex situation is thought to require overt reasoning on declarative knowledge, namely, on facts pertaining to premises, options for action, and outcomes of actions that embody the pertinent previous experience. An alternative possibility was investigated: that overt reasoning is preceded by a nonconscious biasing step that uses neural systems other than those that support declarative knowledge. Normal participants and patients with prefrontal damage and decision-making defects performed a gambling task in which behavioral, psychophysiological, and self-account measures were obtained in parallel. Normals began to choose advantageously before they realized which strategy worked best, whereas prefrontal patients continued to choose disadvantageously even after they knew the correct strategy. Moreover, normals began to generate anticipatory skin conductance responses (SCRs) whenever they pondered a choice that turned out to be risky, before they knew explicitly that it was a risky choice, whereas patients never developed anticipatory SCRs, although some eventually realized which choices were risky. The results suggest that, in normal individuals, nonconscious biases guide behavior before conscious knowledge does. Without the help of such biases, overt knowledge may be insufficient to ensure advantageous behavior.
The somatic marker hypothesis proposes that both the amygdala and the orbitofrontal cortex are parts of a neural circuit critical for judgment and decision-making. Although both structures couple exteroceptive sensory information with interoceptive information concerning somatic/emotional states, they do so at different levels, thus making different contributions to the process. We define "primary inducers" as stimuli that unconditionally, or through learning (e.g., conditioning and semantic knowledge), can (perceptually or subliminally) produce states that are pleasurable or aversive. Encountering a fear object (e.g., a snake), a stimulus predictive of a snake, or semantic information such as winning or losing a large sum of money are all examples of primary inducers. "Secondary inducers" are entities generated by the recall of a personal or hypothetical emotional event or perceiving a primary inducer that generates "thoughts" and "memories" about the inducer, all of which, when they are brought to memory, elicit a somatic state. The episodic memory of encountering a snake, losing a large sum of money, imagining the gain of a large sum of money, or hearing or looking at primary inducers that bring to memory "thoughts" pertaining to an emotional event are all examples of secondary inducers. We present evidence in support of the hypothesis that the amygdala is a critical substrate in the neural system necessary for triggering somatic states from primary inducers. The ventromedial cortex is a critical substrate in the neural system necessary for the triggering of somatic states from secondary inducers. The amygdala system is a priori a necessary step for the normal development of the orbitofrontal system for triggering somatic states from secondary inducers. However, once this orbitofrontal system is developed, the induction of somatic states by secondary inducers via the orbitofrontal system is less dependent on the amygdala system. Perhaps the amygdala is equivalent to the hippocampus with regard to emotions, that is, necessary for acquiring new emotional attributes (anterograde emotions), but not for retrieving old emotional attributes (retrograde emotions). Given the numerous lesion and functional neuroimaging studies illustrating the involvement of the amygdala in complex cognitive and behavioral functions, including "social cognition," we suggest that this involvement is a manifestation of a more fundamental function mediated by the amygdala, which is to couple stimuli/entities with their emotional attributes, that is, the processing of somatic states from primary inducers.
Poor social judgment and decision-making abilities have often been attributed to people who have suffered injury to the ventromedial prefrontal cortex (VMPFC). However, few laboratory tests of decision-making have been conducted on these patients. The exception to this is the Iowa Gambling Task which has often, but not always, demonstrated differential performance between patients and controls. Results from patients with prefrontal cortex lesions on a novel test of decision-making are presented. Participants explored and chose from pairs of gambles that differed in their underlying distributions, primarily in the variance of their respective outcomes. In accordance with many findings from the behavioral decision-making literature, both young normal participants and older patient controls demonstrated a marked avoidance of risk and selected largely from secure, low variance gambles. In contrast, patients with ventromedial lesions were divided into two clear sub-groups. One group behaved similarly to normals, showing a risk-averse strategy. The other group displayed a distinctive risk-seeking behavior pattern, choosing predominantly from the high-variance, high-risk decks. This research demonstrates some of the advantages of using methods and theories from traditional decision-making research to study the behavior of patients, as well as the benefits of examining individual participants, and provides new insights into the nature of the decision-making deficit in patients with ventromedial prefrontal cortex lesions.
The somatic marker hypothesis posits that deficits in emotional signalling (somatic states) lead to poor judgment in decision-making, especially in the personal and social realms. Similar to this hypothesis is the concept of emotional intelligence, which has been defined as an array of emotional and social abilities, competencies and skills that enable individuals to cope with daily demands and be more effective in their personal and social life. Patients with lesions to the ventromedial (VM) prefrontal cortex have defective somatic markers and tend to exercise poor judgment in decision-making, which is especially manifested in the disadvantageous choices they typically make in their personal lives and in the ways in which they relate with others. Furthermore, lesions to the amygdala or insular cortices, especially on the right side, also compromise somatic state activation and decision-making. This suggests that the VM, amygdala and insular regions are part of a neural system involved in somatic state activation and decision-making. We hypothesized that the severe impairment of these patients in real-life decision-making and an inability to cope effectively with environmental and social demands would be reflected in an abnormal level of emotional and social intelligence. Twelve patients with focal, stable bilateral lesions of the VM cortex or with right unilateral lesions of the amygdala or the right insular cortices, were tested on the Emotional Quotient Inventory (EQ-i), a standardized psychometric measure of various aspects of emotional and social intelligence. We also examined these patients with various other procedures designed to measure decision-making (the Gambling Task), social functioning, as well as personality changes and psychopathology; standardized neuropsychological tests were applied to assess their cognitive intelligence, executive functioning, perception and memory as well. Their results were compared with those of 11 patients with focal, stable lesions in structures outside the neural circuitry thought to mediate somatic state activation and decision-making. Only patients with lesions in the somatic marker circuitry revealed significantly low emotional intelligence and poor judgment in decision-making as well as disturbances in social functioning, in spite of normal levels of cognitive intelligence (IQ) and the absence of psychopathology based on DSM-IV criteria. The findings provide preliminary evidence suggesting that emotional and social intelligence is different from cognitive intelligence. We suggest, moreover, that the neural systems supporting somatic state activation and personal judgment in decision-making may overlap with critical components of a neural circuitry subserving emotional and social intelligence, independent of the neural system supporting cognitive intelligence.
The paper examines the literature that attempts to resolve the equity premium and risk free rate puzzles. It demonstrates that the puzzles will confront any model of asset prices that relies on three crucial assumptions: preferences have a particular parametric form, asset markets are complete, and asset trade is frictionless. A survey of the literature that relaxes these assumptions reveals that there are now several plausible explanations of the seemingly low risk free rate, but the large size of the equity premium remains a puzzle.
This paper explores the consequences of cognitive dissonance, coupled with time-inconsistent preferences, in an intertemporal decision problem with two distinct goals: acting decisively on early information (vision) and adjusting flexibly to late information (flexibility). The decision maker considered here is capable of manipulating information to serve her self-interests, but a tradeoff between distorted beliefs and distorted actions constrains the extent of information manipulation. Building on this tradeoff, the present model provides a unified framework to account for the conformity bias (excessive reliance on precedents) and the confirmatory bias (excessive attachment to initial perceptions).
