We enrich the choice task of responders in ultimatum games by allow- ing them to independently decide whether to collect what is offered to them and whether to destroy what the proposer demanded. Such a multidimensional response format intends to cast further light on the motives guiding...

We investigate experimentally whether collective choice matters for individual attitudes to ambiguity. We consider a two-urn Ellsberg experiment: one urn offers a 45% chance of winning a fixed monetary prize, the other an ambiguous chance. Participants choose either individually or in groups of...

We report the results of an original experiment that was designed to test the strength and robustness of the attraction effect. Rather than the usual simple tests for this effect, we consider a conceptually simple consumer purchasing task where alternatives are however difficult to evaluate. For...

In the hybrid game, one proposer confronts two responders with veto power: one responder can condition his decisions on his own offer but the other cannot. We vary what the informed responder knows about the offers as well as the uninformed responder's conflict payoff. Neither variation affects...

Being a "jack-of-all-trades" increases the probability of running an entrepreneurial venture successfully; but what happens to "jack-of-few-trades" who lack sufficient skills? This paper investigates a possible compensation mechanism between balanced skills and cities, and how this compensatory...

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...

We investigate the role of industry and region-specific conditions for the survival of new businesses in innovative and in other manufacturing industries. The data comprises all German manufacturing start-ups of the 1992 to 2005 period. In contrast to studies for some other countries, we find...

We suggest that procedures of monetarized bidding can facilitate co-operation in Elinor Ostrom type common(s) projects without crowding out communitarian faculties of "self-governance". Axioms securing procedurally egalitarian bidding on the basis of declared monetary evaluations are introduced....

Previous research on market economies characterized by stable framework conditions shows that several regional factors determine start-up activity. Not much is known about what drives entrepreneurship in unstable environments characterized by significant institutional changes that affect the...

Bounded rationality questions backward induction, which however, does not exclude such reasoning when anticipation is easy. In our stochastic (alternating offer) bargaining experiment, there is a certain first-period pie and a known finite deadline. What is uncertain (except for the final...
