Die Verhaltensökonomie und ihre praktischen Implikationen geraten immer stärker in den Fokus auch der deutschen Politik. Individuelle Entscheidungen sollen im Sinne eines "libertären Paternalismus" sanft beeinflusst werden. Die „Nudges“ bestehen in Standardvorgaben, Selbstbindungen und...

In impunity games proposers, like allocators in dictator games, can take what they want; however, responders can refuse offers deemed unsatisfactory at own cost. We modify the impunity game via allowing offers to condition of another participant’s counterfactual generosity intention. For a...

During the last three decades the ascent of behavioral economics clearly helped to bring down artificial disciplinary boundaries between psychology and economics. Noting that behavioral economics seems still under the spell of the rational choice tradition and, indirectly, of behaviorism we...

In standard rational choice modelling decisions are made according to given information and preferences. In the model presented here the 'information technology' of individual decision makers as well as their preferences evolve in a dynamic process. In this process decisions are made rationally...

We experimentally manipulate the efficiency of trust and reciprocity in a modified Investment Game. The aim of our manipulation is to test whether reciprocity is mainly affected by payoff consequences of trust or by intentions underlying it. We find that intentions matter and that consequences...

Experimental studies have shown that trust and reciprocity are effective in increasing efficiency when complete contracting is infeasible. One example is the study by Berg et al. (1995) of the investment game. In this game the person who receives the investment is the one who may reward the...
