Take-it or leave-it offers are probably as old as mankind. Our objective here is, first, to provide a, probably subjectively-colored, recollection of the initial ultimatum game experiment, its motivation and the immediate responses. Second, we discuss important extensions of the standard...

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...

By vetoing one questions mutually efficient agreements. On the other hand the threat of vetoing may prevent exploitation. Based on a generalization of ultimatum bargaining (Suleiman, 1996) we first elicit the responders; certainty equivalents for three different degrees of veto power. Afterwards...

Endogenous timing can help to derive the time structure of decision making instead of assuming it as exogenously given. In our study we consider a homogeneous market where, like in the model of Kreps and Scheinkman (1983), sellers determine sales capacities before prices. Sellers must serve...

A general framework is described specifying how boundedly rational decision makers generate their choices. Starting from a "Master Module"; which keeps an inventory of previously successful and unsuccessful routines several submodules can be called forth which either allow one to adjust behavior...

Applying an indirect evolutionary approach with endogenous preference formation, we show that a legal system can induce players to reward trust even if material incentives dictate to exploit trust. By analyzing the crowding out or crowding in of trustworthiness implied by various verdict rules,...

Ad-hoc contracting allows to quickly react to changes which could be neglected or noticed too late in case of constant contracting. But always deciding anew, e.g., how much and what to order in commercial and what to buy in private life, is too cumbersome. To capture the cognitive burden of...

In an ultimatum bargaining, we investigate lying as falsely stating what one privately knows without, however, excluding that others find out the truth. Specifically, we modify the Acquiring-a-Company game. Privately informed sellers send messages about the alleged value of their company to...
