Whether incentive contracts perform better than trust in terms of productive efficiency is usually explored by principal-agent experiments (most involving only one agent). We investigate this issue in the context of a three-person ultimatum experiment, which is simpler and more neutrally framed...

In the experiment two bureaucrats independently can grant a permit with the profit of the private party depending on when the permit is given. Whereas one bureaucrat can only veto the project, the second one has additional discretion in granting the permit earlier or later. We speak of greasing...

A procurement contract is granted by a bureaucrat (the auctioneer) who is interested in a low price and a bribe from the provider. The optimal bids and bribes are derived based on an iid private cost assumption. In the experiment, bribes are negatively framed (betweensubjects treatment) to...

We study a market in which both buyers and sellers can decide to preempt and set their quantities before market clearing. Will this lead to preemption on both sides of the market, only one side of the market, or to no preemption at all? We find that preemption tends to be asymmetric in the sense...

Conventions can be narrowly interpreted as coordinated ways of equilibrium play, i.e., a specific convention tells all players in a game with multiple strict equilibria which equilibrium to play. In our view, coordination often takes place before learning about the games. Thus, one has to...

This paper considers a procedurally fair provision mechanism that allows members of a small group to determine, through their bids, which project to implement. Previous experiments with (only) costly projects have demonstrated that the mechanism is efficiency enhancing. Our experiment tests...

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...
