The 2007-08 financial crisis exposed poignant examples of ill-judged risk accretion in both tails of the Lorenz curve: concentrations of inappropriate mortgages within low-income neighborhoods, and concentrations of Bernard Madoff’s victims within wealthy, predominantly Jewish...

A probability weighting function w(p) for an objective probability p in decision under risk plays a pivotal role in Kahneman–Tversky prospect theory. Although recent studies in econophysics and neuroeconomics widely utilized probability weighting functions, psychophysical foundations of the...

We provide a preference foundation for decision under risk resulting in a model where probability weighting is linear as long as the corresponding probabilities are not extreme (i.e., 0 or 1). This way, most of the elegance and mathematical tractability of expected utility is maintained and also...

We demonstrate that in simple 2×2 games (cumulative) prospect theory preferences can be (semi-)evolutionarily stable, in particular, a population of players with prospect theory preferences is stable against more rational players, i.e. players with a smaller degree of probability weighting. We...

The slow diffusion of new technology in the agricultural sector of developing countries has long puzzled development economists. While most of the current empirical research on technology adoption focuses on credit constraints and learning spillovers, this paper examines the role of individual...

After the introduction of the euro notes and coins in January 2002, throughout the Economic and Monetary Union member countries there was a widespread feeling that the euro had brought about a significant hike in consumer prices. A substantial discrepancy was evident between inflation as...

When the performance of a risky asset is frequently assessed, the probability of detecting a loss is high, which averts the loss averse investors. This effect is known as myopic loss aversion (MLA). This paper reexamines several recent experimental studies documenting the existence of MLA. A...

The disposition eect is the observation that investors hold winning stocks too long and sell losing stocks too early. A standard explanation of the disposition effect refers to prospect theory and in particular to the asymmetric risk aversion according to which investors are risk averse when...

We study how the framework of classical game theory changes when the preferences of the players are described by Prospect Theory instead of Expected Utility Theory. Specifically, we study the influence of framing effect and probability weighting on the existence and specific structure of Nash...

People care a great deal about their relative economic position and not solely about their absolute economic position. However, behavioral evidence is rare. This paper provides evidence on how the relative income position affects professional sports performances. Our analysis suggests that if a...
