In this paper, we show that behavioral features can be obtained at a group level when the individuals of the group are heterogeneous enough. Starting from a standard model of Pareto optimal allocations, with expected utility maximizers and exponential discounting, but allowing for heterogeneity...

In this paper, we show that behavioral features can be obtained at a group level when the individuals of the group are heterogeneous enough. More precisely, starting from a standard model of Pareto optimal allocations, with expected utility maximizers and exponential discounting, but allowing...

We propose nonparametric definitions of absolute and comparative naiveté. These definitions leverage ex-ante choice of menu to identify predictions of future behavior and ex-post (random) choices from menus to identify actual behavior. The main advantage of our definitions is their independence...

This paper discusses a recently published handbook on neuroeconomics (Glimcher et al., 2009H) and extends the discussion to reasons why this newly emerging discipline should be of interest to behavioral accounting researchers. We evaluate the achieved and potential contribution of neuroeconomics...

Cumulative Prospect Theory (Kahneman, Tversky, 1979, 1992) holds that the value function is described using a power function, and is concave for gains and convex for losses. These postulates are questioned on the basis of recently reported experiments, paradoxes (gain-loss separability...

We investigate the relationship between subjective probabilities of future stock market returns and decisions about stockholding. Specifically, we examine whether acting upon subjective probabilities is confined to individuals with high cognitive skills. We explore this question using data from...

An experiment tested whether and in what circumstances people are more likely to believe an event simply because it makes them better off. Subjects observed a financial asset's historical price chart, and received both an accuracy bonus for predicting the price at some future point, and an...

Several authors have reported an unconditional size effect in returns around earnings announcements. In this study we show how this finding can be understood as resulting from ambiguity aversion. We hypothesize that analyst forecasts for smaller companies are relatively more ambiguous; hence...
