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 studies the pro-social preferences of criminals by comparing the behavior of a group of prisoners in a lab experiment with the behavior of a benchmark group recruited from the general population. We find a striking similarity in the importance the two groups attach to pro-social...

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...

Standard ways of measuring real income are known to be inconsistent with consumer preferences. We provide preference-consistent estimates of real income, based on the income-specific price indices that are consistent with nonhomothetic preferences. We find that existing measures, such as Geary,...

It has been shown that participants in the dictator game are less willing to give money to the other participant when their choice set also includes the option to take money. We examine whether this effect is due to the choice set providing a signal about entitlements in a setting where...

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...

We study the relative importance of intrinsic moral motivation and extrinsic social motivation in explaining behavior in the dictator game. We introduce a novel design that manipulates these two dimensions. The paper offers four main findings. First, intrinsic moral motivation is of fundamental...

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...

The pari passu principle is the most prominent principle in the law of insolvency. We report from a lab experiment designed to study whether People find this principle a fair solution to the bankruptcy problem. The experimental design generates situations where participants work and accumulate...
