Paying more than one could have paid to obtain the same outcome is wasteful. In four experiments, we show that waste aversion can lead people to prefer a more wasteful outcome over a more frugal outcome, as long as it eliminates the feeling of wastefulness. In Study 1, we measured participants' satisfaction with lottery outcomes to find that they a...
Working for a firm engaged in Corporate Social Responsibility (CSR) appeals to potential workers by boosting their self-image and sense of purpose. We propose an additional mechanism: CSR signals a firm's future treatment of workers. Our model links CSR engagement with a firm's propensity to support workers during unforeseen times of need. Under th...
How critical are individual members perceived to be for their group's performance? In this paper, we show that judgments of criticality are intimately linked to considering responsibility. Prospective responsibility attributions in groups are relevant across many domains and situations, and have the potential to influence motivation, performance, a...
What someone knew matters for how we hold them responsible. In three studies, we explore people’s responsibility judgments for negative outcomes to knowledgeable versus ignorant agents. We manipulate whether agents arrived at their knowledge state unintentionally or willfully. In Experiment 1, agents who knew about the harmful consequences of their...

Bermúdez argues for rational framing effects based on normatively appropriate quasi-cyclical preferences. We suggest that this argument conflates preferences over specific outcomes with preferences over outcome aspects. Instead of implying quasi-cyclical preferences, framing affects decisions through standard economic trade-offs. Nonetheless, we de...
Markets are increasingly used as information aggregation mechanisms to predict future events. If policymakers and managers use markets to guide policy and managerial decisions, interested parties may attempt to manipulate the market in order to influence decisions. We study experimentally the willingness of managers to base decisions on market info...
This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching...
Experimental team games provide valuable data to help understand behavior in intergroup conflict. Past research employing team games suggests that individual participation in conflict is driven mostly by parochial cooperation, rather than outgroup spite. We argue that motives in conflict depend on whether conflict is framed and perceived at the gro...
The moral comparison of the three venues of deception—lying, falsely implicating, and nonverbal deception—is a central, ongoing debate in the ethics of deception. To date there has been no attempt to advance in the debate through experimental philosophy. Using methods of experimental economics, we devised a strategic game to test positions in the d...
Significant advancements towards a future of big data genomic medicine, associated with large-scale public dataset repositories, intensify dilemmas of genomic privacy. To resolve dilemmas adequately, we need to understand the relative force of the competing considerations that make them up. Attitudes towards genomic privacy are complex and not well...
How can we maximize what is learned from a replication study? In the creative destruction approach to replication, the original hypothesis is compared not only to the null hypothesis, but also to predictions derived from multiple alternative theoretical accounts of the phenomenon. To this end, new populations and measures are included in the design...

High-power incentives increase productivity through two distinct channels: attracting high-skilled workers and incentivizing high effort. We study experimentally how work mission interacts with these two channels. We construct “private sector firms” offering low base and high piece rate wages and “public sector firms” offering high base and low pie...
In sequential first‐ and second‐price private value auctions, second movers are informed about the first movers' bid with commonly known probability. Equilibrium bidding in first‐price auctions is mostly unaffected, but there are multiple equilibria in second‐price auctions affecting comparative statics across price rules. We show experimentally th...
Wage subsidies can be provided directly to the worker, or indirectly by subsidizing the employer; with reduced cost of labor, employers offer higher wages. The standard literature stipulates that this statutory incidence bears no implications for the economic incidence. We propose and test a mechanism by which indirect subsidies lead to higher soci...
Expectant parents experience a variety of emotions, including joy, anticipation as well as anxiety and fear related to the health of the fetus, the delivery and the newborn. These sources of uncertainty and stress render expectant mothers suspectible to the influence of popular beliefs. We design an experiment to evaluate the widespread Israeli bel...
People lie more when they work as a group rather than alone. However, do people suspect and morally evaluate groups and individuals differently when they are suspiciously successful? In four experiments, we examine whether (a) suspiciously successful individuals and groups are judged and punished differently and (b) individual group members are jud...
Motivated by cycles of intergroup revenge in real-world conflicts, we experimentally test the hypothesis that humans practice group-based reciprocity: if someone harms or helps them, they harm or help other members of that person's group. Subjects played a trust game, then allocated money between other people. Senders whose partners returned more i...
Cognitive impairment has a detrimental influence on the decision-making capabilities of older people. This study investigates the ways in which the time preferences of older adults with mild cognitive impairment (MCI) are influenced by their executive cognitive abilities. Within the framework of this study, older adults underwent a cognitive evalua...
Studies of experimental and betting markets have shown that markets are able to efficiently aggregate information dispersed over many traders. We study information aggregation in Arrow–Debreu markets using a novel information structure. Compared to previous studies, the information structure is more complex, allows for heterogeneity in information...
People are rather dishonest when working on collaborative tasks. We experimentally study whether this is driven by the collaborative situation or by mere exposure to dishonest norms. In the collaborative treatment, two participants in a pair receive a payoff (equal to the reported outcome) only if both report the same die-roll outcome. In the norm...
Economic growth improves the material well-being of all workers. However, when remuneration in the public sector is less sensitive to economic cycles than in the private sector, as is typically the case, economic growth will worsen the position of workers in the public sector relative to workers in the private sector, even though their income impro...
The theoretical literature on collusion in auctions suggests that the first-price mechanism can deter the formation of bidding rings. However, such analyses neglect to consider the effects of failed collusion attempts, wherein information revealed in the negotiation process may affect bidding behavior. We experimentally test a setup in which theory...
We experimentally test the social motives behind individual participation in intergroup conflict by manipulating the perceived target of threat—groups or individuals—and the symmetry of conflict. We find that behavior in conflict depends on whether one is harmed by actions perpetrated by the out-group, but not on one's own influence on the outcome...
Absentmindedness is a special case of imperfect recall which according to Piccione and Rubinstein (1997a) leads to time inconsistencies. Aumann, Hart and Perry (1997a) question their argument and show how dynamic inconsistencies can be resolved. The present paper explores this issue from a descriptive point of view by examining the behavior of abse...
We study first- and second-price private value auctions with sequential bidding where second movers may discover the first movers’ bid. There is a unique equilibrium in the first-price auction and multiple equilibria in the second-price auction. Consequently, comparative statics across price rules are equivocal. We experimentally find that in the first-...
How do people attribute responsibility in situations where the contributions of multiple agents combine to produce a joint outcome? The prevalence of over-determination in such cases makes this a difficult problem for counterfactual theories of causal responsibility. In this article, we explore a general framework for assigning responsibility in mu...
The Aumann (1990) conjecture states that cheap-talk messages do not necessarily help to coordinate on efficient Nash equilibria. In an experimental test of Aumann’s conjecture, Charness (2000) found that cheap-talk messages facilitate coordination when they precede the action, but not when they follow the action. Standard game-theoretical modeling...
Attributions of responsibility play a critical role in many group interactions. This paper explores the role of causal and counterfactual reasoning in blame attributions in groups. We develop a general framework that builds on the notion of pivotality: an agent is pivotal if she could have changed the group outcome by acting differently. In three e...
Pre-play face-to-face communication is known to facilitate cooperation. Various explanations exist for this effect, varying in their dependence on the strategic content of the communication. Previous studies have found similar communication effects regardless of whether strategic communication is available. These results were so far taken to suppor...
Surprisingly high levels of within-group cooperation are observed in conflict situations. Experiments confirm that external threats lead to higher cooperation. The psychological literature suggests proximate explanations in the form of group processes, but does not explain how these processes can evolve and persist. The authors provide an ultimate...
The Aumann (1990) conjecture states that cheap-talk messages do not necessarily help to coordinate on efficient Nash equilibria. I use the example provided by Aumann to study the sequential equilibria of the signaling game in which the sender is modeled as comprising two selves: an acting self and a signaling self. I formalize Aumann’s argument in...
This paper provides a new way to identify conditional cooperation in a real-time version of the standard voluntary contribution mechanism. We define contribution cycles as the number of contributors a player waits for before committing to a further contribution, and use a permutation test on contribution cycles to assign a measure of conditional co...
Conventional wisdom suggests that an increase in monetary incentives should induce agents to exert higher effort. In this paper, however, we demonstrate that this may not hold in team settings. In the context of sequential team production with positive externalities between agents, incentive reversal might occur: an increase in monetary incentives...
Gambling frequencies on single numbers in real casino roulette were displayed in a contour map. This resulted not only in a confirmation that gamblers are subject to middle bias, but also to accessibility effects. The figure allowed us to infer the location of the roulette wheel and croupier from the gambling data, as well as infer bounds on the di...

``Waste not want not'' expresses our culture's aversion to waste. ``I could have gotten the same thing for less'' is a sentiment that can diminish pleasure in a transaction. We study people's willingness to ``pay'' to avoid this spoiler. In one scenario, participants imagined they were looking for a rental apartment, and had bought a subscription t...
In experiments, people behave more cooperatively when they are aware of an external threat, while in the field, we observe surprisingly high levels of within - group cooperation in conflict situations such as civil wars. We provide an explanation for these phenomena. We introduce a model in which different groups vary in their willingness to help e...

We report on an experiment using video technology to manipulate pre-play communication protocols in the lab and to study purely social effects of communication on donations and discrimination between potential receivers. The experimental design eliminates strategic factors by allowing two receivers to unilaterally communicate with an anonymous dict...
The high cost of searching for employers borne by prospective employees increases friction in the labor market and inhibits formation of efficient employer-employee relationships. It is conventionally agreed that mechanisms that reduce the search costs (e.g., internet portals for job search) lower unemployment and improve overall welfare. We demons...
We consider a multitype population model with unobservable types, in which players are engaged in the `mutual help' game: each player can increase her partner's fitness at a cost to oneself. All individuals prefer free riding to cooperation, but some of them, helpers, can establish reciprocal cooperation in a long-term relationship. Such heterogene...

Corruption in the public sector erodes tax compliance and leads to higher tax evasion. Moreover, corrupt public officials abuse their public power to extort bribes from the private agents. In both types of interaction with the public sector, the private agents are bound to face uncertainty with respect to their disposable incomes. To analyse effect...
The experiment disentangles communication and social effect in face-to-face communication. The results question the previous interpretation of communication effects in ultimatum bargaining, and suggest that separate processes, both of a strategic and of an affective-social nature induce cooperative outcomes.
Experimental evidence on gender differences demonstrates that women are generally less trusting and more reciprocating than men in Investment Games. However, existing studies typically use a narrow population consisting of college students. To test the robustness of these findings, we report on an experiment using 18-84-year old participants recrui...
It is commonly accepted that face-to-face communication induces cooperation. The experiment disentangles communication and social effect (replication of Roth, 1995) and examines the components of the social effect with the help of unilateral communication. Results suggest that separate processes, both of a strategic and of an affective-social natur...
