We study the influence of risk and time preferences on trust and trustworthiness by conducting a field experiment in Vietnamese villages and by estimating the parameters of the Cumulative Prospect Theory and of quasi-hyperbolic time preferences. We find that while probability sensitivity or risk...

Andreoni and Sprenger (in press) report evidence that distinct utility functions govern choices under certainty and risk. I investigate the robustness of their result to the experimental design. I find that the effect disappears completely when a multiple price list is used instead of a convex...

This article analyzes the impact of risk on decisions made by the poor within the context of the Individual Development Account (IDA) program. IDA is a matched savings program designed to help low-income households invest in appreciating assets. For these households, the risk involved with...

We investigate intertemporal dominance conditions for comparisons of finite unidimensional streams of outcomes in discrete time. We follow Ekern's [1981, Time dominance efficiency analysis. Journal of Finance, 36, pp.1023-1034] approach based on unanimous net present value comparisons for...

When the discount rate is uncertain, individuals whose preferences are consistent with discounted expected utility, exhibit diminishing impatience. This paper introduces and characterizes a variation of discounted expected utility in which the discount rate depends on the state of the nature...

Numerous experiments have demonstrated the possibility of attitude polarization. For instance, Lord, Ross & Lepper (1979) partitioned subjects into two groups, according to whether or not they believed the death penalty had a deterrent effect, and presented them with a set of studies on the...

Uncertainty has an almost negligible impact on project value in the economic standard model. I show that a comprehensive evaluation of uncertainty and uncertainty attitude changes this picture fundamentally. The analysis relies on the discount rate, which is the crucial determinant in balancing...

The paper analyzes the discount rate under uncertainty. The analysis complements the probabilistic characterization of uncertainty by a measure of confidence. Special cases of the model comprise discounting under smooth ambiguity aversion as well as discounting under a disentanglement of risk...

The paper critically discusses the issue of rationality and choices in economics in both the behavioural and evolutionary approaches. Our study aims, on the one hand, to highlight the scientific contributions of psychology in economics, since psychology, and with it the theoretical approach of...

We study risk attitudes, ambiguity attitudes, and time preferences of 661 children and adolescents, aged ten to eighteen years, in an incentivized experiment. We relate experimental choices to field behavior. Experimental measures of impatience are found to be significant redictors of health...
