This paper provides empirical evidence that distinguishes between alternative conceptualizations of the risky decision making process. Two studies investigate whether cross-situational differences in choice behavior should be interpreted in the expected utility framework as differences in risk...

This paper investigates equilibrium R&D investment strategies of firms endowed with different innovation potentials. To address this issue, this paper permits two stages of innovation and develops a simple stochastic game model involving two firms. It is shown that in equilibrium, a leader in...

In this study, respondents from the P.R.C., U.S.A., Germany, and Poland were found to differ in risk preference, as measured by buying prices for risky financial options. Chinese respondents were significantly less risk-averse in their pricing than Americans when risk preference was assessed in...

We investigate a basic premise of prospect theory: that the valuation of gains and losses is separable. In prospect theory, gain-loss separability implies that a mixed gamble is valued by summing the valuations of the gain and loss portions of that gamble. Two experimental studies demonstrate a...

A number of recent papers have examined the environmental and genetic sources of individual differences in economic and financial decision making. Here we contribute to this burgeoning literature by extending it to a number of key behavioral anomalies that are thought to be of importance for...

The process by which individuals learn from feedback when making recurrent choices among ambiguous alternatives is explored. We describe an experiment in which subjects solve a variant of the classic armed-bandit problem of dynamic decision theory, set in the context of airline choice. Subjects...

One of the fundamental postulates of rational choice is that preferences manifested by an individual towards alternatives should only depend on the merits of these alternatives and not on extraneous, irrelevant factors. Violations of this basic principle, so-called preference reversals, have...

Averaging estimates is an effective way to improve accuracy when combining expert judgments, integrating group members' judgments, or using advice to modify personal judgments. If the estimates of two judges ever fall on different sides of the truth, which we term bracketing, averaging must...

Certainty equivalence (CE) and probability equivalence (PE) methods are the two most frequently used procedures for constructing von Neumann-Morgenstern utility functions. In this paper, we compare these methods experimentally, using a two-stage within-subject design. By asking subjects first...

Discrete choice models of demand have typically been estimated assuming that prices are exogenous. Since unobservable (to the researcher) product attributes, such as coupon availability, may impact consumer utility as well as price setting by firms, we treat prices as endogenous. Specifically,...
