We integrate a case-based model of probability judgment with prospect theory to explore asset pricing under uncertainty. Research within the "heuristics and biases" tradition suggests that probability judgments respond primarily to case-specific evidence and disregard aggregate characteristics...

Previous endowment effect experiments have examined circumstances in which people encounter a single unit of a good (e.g., one chocolate). We contrast single-unit treatments with multiple-unit treatments in which participants encounter several units of a good (e.g., five chocolates). We observe...

We provide large sample evidence that past price extremes influence investors' trading decisions. Volume is strikingly higher, in both economic and statistical terms, when the stock price crosses either the upper or lower limit of its past trading range. This increase in volume is more...

In this paper, we describe three different experiments that explore participants’ risk attitude. When we analyzed the average results, we found that participants behave as the S-shape value function predicts. However, breaking the data down on the individual level reveals that the S-shape is...

Prospect theory (PT), which relies on subjects’ behavior as observed in laboratory experiments, contradicts the behavior predicted by the Expected Utility (EU) paradigm. Having wealth of $100,000 or having wealth of $90,000 and winning $10,000 in a lottery is the same by EU paradigm but not...

This short paper demonstrates that the claim of Cumulative Prospect Theory (CPT) that people are risk seeking for loss prospects, which confirmed a hypothetical assumption of the earlier Prospect Theory (PT), appears to be merely a result of using a specific form of the probability weighting...

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...
