Economists typically predict that people are inherently selfish; however, experimental evidence suggests that this is often not the case. In particular, delegating a choice (such as a wage) to the performing party may imbue this party with a sense of responsibility, leading to improved outcomes...

In a real effort experiment with repeated competition we find striking differences in how the work effort of men and women responds to previous wins and losses. For women, losing per se is detrimental to productivity, but for men, a loss impacts negatively on productivity only when the prize at...

The desire to avoid the shame of being dependent on government aid is often cited as a cause of low welfare take-up rates. In contrast to other obstacles, such as transaction costs or a lack of information, little empirical research has been conducted on how stigma affects social benefits...

Accounting for sample selection is a challenge not only for empirical researchers, but also for the agents populating our models. Yet most models abstract from these issues and assume that agents successfully tackle selection problems. We design an experiment where a person who understands...

We propose two novel axioms for qualitative probability spaces (Bernstein, 1917; de Finetti, 1937; Koopman, 1940; Savage, 1954): (i) unlikely atoms, which requires that there is an event containing no atoms that is at least as likely as its complement; and (ii) third-order atom-swarming, which requires that...
