We study experimentally how taxpayers choose between two tax regimes to fund a public good. The first-best tax regime imposes a general, distortion-free income tax. However, this tax cannot be enforced. The second-best alternative supplements the income tax by a specific commodity tax. This tax...

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 der...

A rigorous reconstruction of scenario-based real choice making reveals the incompleteness of decision-modeling and the practical prevalence of uncertainty. Theoretically complete models conceal it. As a remedy a scenario-based procedure of coping with uncertainty can prescribe how the boundedly...

We confront allocator participants with different sharing games in a within subjects design: the Nash demand game, the ultimatum game, the yes-no-game and the impunity game. We allow participants to opt out rather than play the game under consideration. Beside choice data we also collect belief...

We experimentally investigate competition in innovation in a patent race scenario. Pairs of subjects compete as seller firms on a duopoly market, engaging in risky search investments. Successful innovation is rewarded through temporary monopoly rents. Throughout the interaction, subjects receive...

Does geographic distance or the perceived social distance between subjects significantly affect proposer and responder behavior in ultimatum bargaining? To answer this question, subjects play a one-shot ultimatum game with three players (proposer, responder, and a passive dummy player) and...

Can one define and test the hypothesis of (un)bounded rationality in stochastic choice tasks without endorsing Bayesianism? Similar to the state specificity of assets, we rely on state-specific goal formation. In a given choice task, the list of state-specific goal levels is optimal if one...

Facing a stochastic market wage, which is independent of their own hiring policy, employers offer contracts specifying fixed wage, revenue share and employment duration. In ongoing employment relations it depends on the treatment whether fixed wages can be only increased or also decreased. Will...

When two or more agents compete for a bonus and the agents' productivity in each of several possible occurrences depends stochastically on (constant) effort, the number of times that are checked to assign the bonus affects the level of un-certainty in the selection process. Uncertainty, in turn,...
