Many verifiable contracts are impossible or difficult to enforce. This applies to contracts among family and friends, contracts regulating market transactions, and sovereign debt contracts. Do such non-enforceable contracts matter? We use a version of the trust game with participants from Norway...

The paper reports from an experiment studying how the aversion to lying is affected by non-economic dimensions of the choice situation. Specifically, we study whether people are more or less likely to lie when the content of the lie is personal, when they base decisions on intuition, and when...

We report an experimental test of the four touchstones of rationality in choice under risk – utility maximization, stochastic dominance, expected-utility maximization and small-stakes risk neutrality – with students from one of the best universities in the United States and one of the best...

Can lab experiments on student populations serve to identify the motivational forces present in society at large? We address this question by conducting, to our knowledge, the first study of social preferences that brings a nationally representative population into the lab, and we compare their...

Choices involving risk significantly aect the distribution of income and wealth in society, but there is probably no more contentious question of justice than how to allocate the gains and losses that inevitably result from risky choices. This paper reports the results from the first experiment,...

The debate between Engelmann and Strobel (2004, 2006) and Fehr, Naef, and Schmidt (2006) highlights the important question of the extent to which lab experiments on student populations can serve to identify the motivational forces present in society at large. We address this question by...

This paper shows one way of generalizing the standard framework of inequality measurement to allow for a distinction between fair and unfair inequalities. We introduce the unfairness Lorenz curve and the unfairness Gini, which are generalizations of the standard versions of the Lorenz curve and...
