Livestreaming platforms (LSP) as a shopping medium have grown in recent years. This commercial platform offers an unprecedented opportunity for vendors to deliver their services and create value for consumers. Vendors seeking a competitive advantage are finding that LSP enables them to promote their products and generate digital data rapidly for re...
Security is a fundamental human need, and a nascent industry, which surprisingly, has garnered scant attention hitherto in the marketing and services literature. In contemporary society, advanced technologies, social dynamics, and environmental changes have contributed to a growing preoccupation with private security. Inter alia, the rising frequen...
Marketing and consumer research use a variety of data and electronic measurement devices for research, theory-building, and applied decision-making. Managing data deluge produced by ‘smart devices’ and internet of things (IoT) actuators and sensors is one of the challenges faced by managers when using IoT systems. With the advent of the cloud-based...
The latest effort in delivering computing resources as a service to managers and consumers represents a shift away from computing as a product that is purchased, to computing as a service that is delivered to users over the internet from large-scale data centers. However, with the advent of the cloud-based IoT and artificial intelligence (AI), whic...

A prominent recurring theme in social comparison is the concept that individuals are not indifferent to the results that others achieve, and typically seek pleasure while avoiding pain. However, in some cases they behave atypically–counter to this principle. The purpose of this research is to investigate one atypical response, namely gluckschmerz–a...
This investigation attempts to assess quantitatively past studies on advertising-appeal differences and scale them on a common metric. On the basis of a large and unique dataset using comparative meta-analysis, this study provides measures of the relative impact of seven types of appeals. Meta-regression was used to test whether certain moderators...
Message appeals are a key component of communication campaigns and an important source of campaign influence. However, research on them is heavily fragmented and it is difficult to generalize findings from the many diverse field studies. Based on a large and unique data set using quantitative and qualitative meta-analyses, this research provides me...
A model and generalized least squares (GLS) analysis is presented for paired comparisons replicated within individuals. This analysis is applicable to any pairwise judgement or datum that is interprétable as a preference or perceptual difference, and it permits any (unknown) pattern of correlations among the paired comparisons. Exact individual‐lev...
This research illustrates the power of reputation, such as that embodied in brand names, demonstrating that names can enhance objective product efficacy. Study participants facing a glaring light were asked to read printed words as accurately and as quickly as they could, receiving compensation proportional to their performance. Those wearing sungl...
This paper analyzes the effect of competition on product demonstration decisions. Pre-purchase product demonstration enables marketers to differentiate products that are ex-post differentiated but are judged according to perceived fit, rather than actual fit, due to pre-purchase consumer uncertainty. Imbalanced competition accompanied by fit uncert...
The purpose of this study is to determine whether customers' diurnal preferences, tested at different times of the day, affect their responses and behavior. Three studies explore whether synchrony between the peak circadian arousal period and the time of participant testing influenced participants' temporal perception and behavior. Overall, the res...
The authors propose that participation in market research can determine consumers' experiences with and evaluations of marketing services/products. Building on and extending a prior finding that expectation to evaluate a service (or product) leads to more negative evaluations, this research investigates the robustness, process, and consequences of...
This paper investigates the processes underlying consumers’ memory-based store price judgments. The numerosity heuristic implies that the greater the number of relatively lower priced products at a store that consumers can recall, the lower will be their overall price image of the store. That is, people use the number of recalled low-price products...
Data obtained from the intention-to-buy scale often are used for early product screening. The authors discuss current procedures to evaluate these data and indicate the minor rote that risk assessment has played. Evaluation rules that incorporate the risk factor are presented, and their usefulness for product selection is discussed.
The findings and value of market research depend critically on consumers’ understanding of the research objectives and their roles. The present research presents a three-phase investigation of the impact of research participants’ theories about their roles: (a) identifying the theories, (b) testing the process consequences of participants’ role the...

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...
Behavioral pricing research has shown consumers to have lower and upper price thresholds, represented by an inverted U-shaped price acceptability function. We propose another basic reaction to price, namely, "lower price is better," represented by a decreasing acceptability function without a lower price threshold. A set of variables is hypothesize...
Customers' evaluations of quality and satisfaction are critical inputs in the development of marketing strategies. Given the increasingly common practice of asking for such evaluations, buyers of products (e.g., cars) and services (e.g., hotels, educational programs/courses) often know in advance that they subsequently will be asked to provide thei...

When major reasons of fault are presented in a pruned format, people fail to transfer the proportions of the omitted categories to the “all-other-problems” category. The present research investigated the underlying judgmental processes and the effect of domain knowledge on this phenomenon, known as pruning bias. In Experiment 1, although people wit...
There are conflicting hypotheses regarding the effect of a surprising outcome on hindsight judgment. According to the hypothesis presented in this paper, high levels of surprise will lead to the elimination or reversal of hindsight bias. The feeling of surprise serves as a cue to subjects making them aware of the fact that outcome information is la...
This paper investigates the psychometric properties of three measures of subjective uncertainty---a zero-to-hundred subjective probability scale and two seven point rating scales. Individual level analysis applied to data obtained from two separate studies suggests that the scales produce fairly similar results: The inter-response mode correlations...
Research conducted by Mazursky and Ofir (1990) suggests that the reaction to a surprising event may take the form of ‘I could not have expected it to happen’ rather than ‘I knew it all along,’ as implied by the hindsight bias. Mazursky and Ofir (1990) postulated that people may acknowledge their surprise at highly unexpected outcomes. When asked to...
A model for dimensionalizing and scaling perceived risk is presented. The scaling procedure provides risk values at the brand and category level on each of several risk dimensions. The model is illustrated with business managers' risk assessments of microcomputer profiles. The relative importance of various intrinsic and extrinsic cues in determini...
An item response theory is combined with a main-effect demand function for predicting product sales from perception and price. In the sales function perception is measured on a log interval scale, whereas price is measured on its usual ratio scale. The most important main effect in this function represents a composite of unspecified attributes and...
It has been hypothesized and demonstrated in previous research that individuals′ recall of predictive judgments is typically distorted by knowledge of the outcomes of the events predicted. This is attributed to the tendency to downgrade the surprise element associated with the outcomes and the adoption of an “I knew it all along” attitude. The pres...
In two experiments using "Bayesian" probability judgment tasks, we examined the effects of numerical values of base rates and case cues, the degree of consistency in these values, and the narrowness of the populations to which these cues are pertained. Both experiments showed that the "base-rate fallacy" is observed only when (a) one combines base...

A stochastic postulate is given for the multiple-item, successive-intervals scaling of populations. The logistic equivalent of this postulate provides an aggregate item response model in which a unidimensional submodel may be nested. This reduction provides a subtractive conjoint measurement of several items and stimuli on the same latent scale. Ge...
The study investigates the extent to which the false alarm (i.e., P( D H ̄)) is utilized in judgment under uncertainty. The main findings are (1) this cue is utilized by subjects when provided with a numerically low base-rate (i.e., P(H)) and a high hit-rate (i.e., P( D H)). Under these conditions the false alarm helps resolve the inconsistency bet...
In this paper a data analysis tool for analyzing highly correlated time series data is suggested. The main objective is to unify multiple time series into a single series and then apply a univariate method for the purpose of prediction. This method is essentially efficient for analyzing multiple time series with sparse data. Several time series dat...
Three frequently used response formats -- Likert, semantic-differential and single anchor (Stapel) -- are compared via analysis of covariance structures. The cumulative results based on four data sets provided evidence inconsistent with previous research suggesting that these formats are interchangeable. Consistently across studies, the semantic-di...
The problem of multicollinearity in linear models is reviewed. Diagnostic measures for detection, analysis of the effects, and localization of multicollinearity are presented. It is recommended that OLS estimates should not be used without a proper diagnostic. The traditional remedial measures, i.e., omission of variables from the model and princip...
This research investigated contextual effects on consumer cue-utilization policies in making judgments under uncertainty. Two studies suggested that the utilization of base and case information varied as a function of the numerical values of the cues and covaried with the changes in the perceived relevance of each cue. The second study showed that...
