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...

In two-person generosity games the proposer's agreement payoffis exogenously given whereas that of the responder is endogenouslydetermined by the proposer's choice of the pie size. Earlier resultsfor two-person generosity games show that participants seem to caremore for eciency than for equity....

A firm with stochastic demand can rely on hired hands when demand is low and rent additionallabour when demand is higher. For high demand this implies the co-employmentof hired hands, paid directly by the firm, and of rented hands who are paid by a rentalagency. This may cause severe problems if...

In generosity games, one agreement payoff is exogenously given, whereas the other is endogenously determined by the proposer's choice of the "pie" size. This has been shown to induce pie choices which are either efficiency or equality seeking. In our experiment, before playing the generosity...

Bidding challenges learning theories since experiences with the same bid vary stochastically:the same choice can result in either a gain or a loss. In such an environment thequestion arises how the nearly universally documented phenomenon of loss aversion affectsthe adaptive dynamics. We analyze...

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 modify the Acquiring-a-Company game to study lying in ultimatum bargaining. Privately informed sellers send messages about the alleged value of their company to potential buyers. Via random information leaks, buyers can learn the true value before proposing a price which the seller finally...

Game and decision theory start from rather strong premises. Preferences, represented by utilities, beliefs represented by probabilities, common knowledge and symmetric rationality as background assumptions are treated as “given.” A richer language enabling us to capture the process leading...
