Even if contract enforcers are as opportunistic as ordinary traders, a system of adjudication can increase the degree to which contractual obligations on large anonymous markets are fulfilled. Only if arbitrators receive a fixed income, occasional mistakes will not favour the untrustworthy. It...

Human decision making is a process guided by different and partly competing motivations that can each dominate behavior and lead to different effects depending on strength and circumstances. "Over-stylizing" neglects such competing concerns and context-dependence, although it facilitates the...

When commenting on Vernon Smith's inspiring paper, we first argue that game theory in its "reasoning about knowledge" tradition is not truly behavioral and try to categorize different approaches. We then go on by considering specific topics, discussed by Vernon Smith, before concluding with some...

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...

Standard economic explanations of good conduct in trade rely almost exclusively on future-directed extrinsic motivations induced by material incentives. But intrinsic motives to behave trustworthily and to punish untrustworthiness do support trade. In our model, intrinsically motivated players...

This paper brings together views on choice making as have been developed in philosophy, psychology, and economics. Starting from specific examples the relative merits of different approaches are discussed. The conclusion that models of boundedly rational behavior are the future of social science...

Economists usually treat human behavior as being determined by the shadow of the future, while most other social scientists point to the shadow of the past. This paper considers experimental evidence relevant to the controversy and tries to reconcile both explanations of human behavior with each...

Taking seriously the philosophical foundations of classical strategic theories of choice-making we scrutinize to what extent planning on equilibrium strategies can be justified "eductively" among rational players and how this can be utilizes to analyze games by their "game-like" sub-structures,...
