We study gender differences in altruism by examining a modified dictator game with varying incomes and prices. Our results indicate that the question "which is the fair sex?" has a complicated answer - when altruism is expensive, women are kinder, but when it is cheap, men are more altruistic....

The most distinctive prediction of prospect theory is the fourfold pattern (FFP) of risk attitudes. People are said to be (1) risk-seeking over low-probability gains, (2) risk-averse over low-probability losses, (3) risk-averse over high-probability gains, and (4) risk-seeking over...

We find that large increases in age do not reduce the endowment effect, supporting the hypothesis that people have reference-dependent preferences which are not changed by repeated experience getting and giving up goods.

In this paper we examine how risk attitudes change with age. We present participants from age 5 to 65 with choices between simple gambles and the expected value of the gambles. The gambles are over both gains and losses, and vary in the probability of the non-zero payoff. Surprisingly, we find...

We present an experiment investigating why contributions decline in repeated public goods games. To distinguish between alternative explanations for this decrease we use a strategy method to elicit strategies in a simple two-stage public goods game. By repeating the game with new opponents...
