Economists have been theorizing that other-regarding preferences influence decision making. Yet, what are the corresponding psychological mechanisms that inform these preferences in laboratory games? Empathy and Theory of Mind (ToM) are dispositions considered to be essential in social...

Abundant evidence suggests that high levels of contributions to public goods can be sustained through self-governed monitoring and sanctions. This experimental study investigates the effectiveness of decentralized sanctioning institutions where punishment opportunities are restricted to agents...

We test the implications of ambiguity aversion in a principal-agent problem with multiple agents. When output distributions are uncertain, models of ambiguity aversion suggest that tournaments may become more attractive than independent wage contracts, in contrast to the case where output...

Using a laboratory experiment, we examine whether informal monetary sanctions can lead to better coordination in a repeated minimum effort coordination game. While most groups first experience inefficient coordination, the efficiency increases substantially after introducing an ex post...

Often, a person will become an entrepreneur only after a period of dependent employment, suggesting that occupational choices precede entrepreneurial choices. We investigate the relationship between occupational choice and self-employment. The findings suggest that the occupational choice of...

The notion of choice inconsistency is widely spread in the literature on behavioral economics. Several approaches were used to account for the observation that people reverse their choices over time. This paper aims to explain the formation of resolutions regarded as internal self-binding...

The satisficing approach is generalized and applied to finite n-person games. Based on direct elicitation of aspirations, we formally define the concept of satisficing, which does not exclude (prior-free) optimality but includes it as a border case. We also review some experiments on strategic...

In-group favoritism in social dilemma situations is one of the main findings of studies in Social Identity Theory. We investigate what causes the in-group bias: is it due to mere group affiliation or, alternatively, is guilt-aversion a possible explanation? We induce group membership in a...

Theoretically and experimentally, we generalize the analysis of acquiring a company (Samuelson and Bazerman 1985) by allowing for competition of both, buyers and sellers. Naivety of both is related to the idea that higher prices exclude worse qualities. While competition of naive buyers...

In economic theory, utility depends on past, present and future outcomes. The experiment described in this paper suggests that utility also depends on people's attitudes, and that it can easily be manipulated through these attitudes. The results imply, ?rst, that purely outcome-based models of...
