Behavioral researchers use analysis of variance (ANOVA) tests of differences between treatment means or chi-square tests of differences between proportions to provide support for empirical hypotheses about consumer behavior. These tests are typically conducted on data from “between-subjects” experiments in which participants were randomly assigned to conditions. We show that, despite using internally valid experimental designs such as this, aggregation biases can arise in which the… Expand
BANOVA: Bayesian Analysis of Experiments in Consumer Psychology
This article introduces Bayesian extension of ANOVA for the analysis of experimental data in consumer psychology. The approach, called BANOVA, addresses some common challenges that consumerExpand
What If Consumer Experiments Impact Variances as Well as Means? Response Variability as a Behavioral Phenomenon
This essay discusses the fact that in many cases means and variances of probability distributions are confounded and cannot be separated, which poses particular problems for analysis andExpand
Environments, unobserved heterogeneity, and the effect of market orientation on outcomes for high-tech firms
The interaction between market orientation and facets of the environment is theoretically compelling and is hence the primary interaction studied in market orientation literature. Yet empiricalExpand
A meta-analysis of extremeness aversion
Abstract Using a meta-analysis of 142 experimental observations, this work examines the influence of different research design and outcome measures on extremeness aversion (i.e., the propensity toExpand
The compromise effect denotes the finding that brands gain share when they become the intermediate rather than an extreme option in a choice set (Simonson 1989). Despite the robustness and importanceExpand
Editorial: Errors in the Variables, Unobserved Heterogeneity, and Other Ways of Hiding Statistical Error
One research function is proposing new scientific theories; another is testing the falsifiable predictions of those theories. Eventually, sufficient observations reveal valid predictions. For theExpand
Computing the average 'effect', the difference in means of the dependent variable between conditions, is by far the most common way of analyzing experimental data. In many settings, however, theExpand
Heterogeneity in the Consistency of Best–Worst Scale Responses
Best–worst Scaling is one of the dominant measurement approaches in choice experimentation. When employed it provides substantial information on peoples’ preferences without making choice tasksExpand
Theory and external validity
Winer (1999 [this issue]) proposes that external validity concerns require more attention in theoretical research. The author argues that one cannot “enhance” external validity by choosing one methodExpand
Cognition and Individual Differences in the Newsvendor Problem : Behavior Under Dual Process Theory
Previous research has shown that individuals systematically and persistently deviate from the profit maximizing quantity when solving a newsvendor problem. This research posits that Dual ProcessExpand


Within-subjects designs: To use or not to use?
This article considers the several factors pertinent to deciding whether a withinor between-subjects design should be employed for a research application. A general principle favoring within-subjectsExpand
Heterogeneity and purchase event feedback in choice models: An empirical analysis with implications for model building
Abstract This paper evaluates empirically the most commonly used methods of incorporating heterogeneity and purchase event feedback in choice models. We evaluate each method with respect to modelExpand
Hypothesized and Confounded Explanations in Theory Tests: A Bayesian Analysis
Traditional views of research methodology hold that little, if any, useful information can be obtained from one or more confounded studies, unless the results from one study rule out or falsify anExpand
Uniqueness Issues in the Decompositional Modeling of Multiattribute Overall Evaluations: An Information Integration Perspective
The author reviews how methods developed within the information integration paradigm can be used to study consumers’ overall evaluations of choice alternatives. Methods are presented for determiningExpand
The Choice Theory Approach to Market Research
This paper surveys economic choice theory, stressing developments that permit use of data from psychometric and conjoint experiments to produce market demand forecasts. Alternatives to the widelyExpand
The Role of External Validity in Theoretical Research
Calder, Phillips, and Tybout (1982) have criticized my analysis of the role of external validity in theoretical consumer research (Lynch 1982). In particular, they disputed my argument thatExpand
A Rational Reconstruction of the Compromise Effect: Using Market Data to Infer Utilities
This article explores the possibility that consumers use market data to make inferences about product utilities. The argument is made by means of an example based on the "compromise effect" found inExpand
Investigating Heterogeneity in Brand Preferences in Logit Models for Panel Data
In analyzing panel data, the issue of heterogeneity across households is an important consideration. If heterogeneity is present but is ignored in the analysis, it will result in biased andExpand
Self-generated validity and other effects of measurement on belief, attitude, intention, and behavior.
Drawing from recent developments in social cognition, cognitive psychology, and behavioral decision theory, we analyzed when and how the act of measuring beliefs, attitudes, intentions, and behaviorsExpand
Asymmetric Decoy Effects on Lower-Quality versus Higher-Quality Brands: Meta-analytic and Experimental Evidence
Prior research demonstrates that adding decoys to choice sets can increase choice shares of brands similar to decoys while reducing shares of brands dissimilar to decoys. Such effects have beenExpand
