Broken Windows: the metaphor has changed New York and Los Angeles. Yet it is far from un-disputed whether the broken windows policy was causal for reducing crime. In a series of lab experiments we put two components of the theory to the test. We show that first impressions and early punishment...

We experimentally study the effect of asymmetry on cooperation in a 40 period prisoner's dilemma game in fixed partner design. We distinguish between a high and low payoff symmetric prisoner's dilemma and an asymmetric game combined out of both symmetric ones. Asymmetry significantly decreases...

We experimentally investigate purchase decisions with linear and nonlinear pricing under risk. The experiment is based on a single period stochastic inventory problem with endogenous cost. It extends classic binary lottery experiments to test standard decision theoretic predictions concerning...

We conduct an experiment to test standard theoretical predictions concerning switching behavior in a rebate and a discount scheme. Beyond theoretical expectations we find that rebate and discount schemes exert a significant attraction that enhances the potentially exclusionary effect of the...
