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...

A sequentially rationalizable choice function is a choice function which can be obtained by applying sequentially a fixed set of asymmetric binary relations (rationales). A Rational ShortlistMethod (RSM) is a choice function which is sequentially rationalizable by two rationales. These concepts...

Consider any situation involving uncertainty, where the random variable of interest (e.g., payoff) is X. Let there exist a random variable, say Y, which represents the uncertainty intrinsic to the situation, and let there exist a function g such that X=g(Y). Our contention is that, once the...

In this paper we experimentally test a theory of boundedly rational behavior in a "lemons market." We analyzed two different market designs, for which perfect rationality implies complete and partial market collapse, respectively. Our empirical observations deviate substantially from these...

We introduce the notion of strategic awareness in experimental games which captures the idea that subjects realize they are playing a game and thus have to form beliefs about others' actions in order to play well. The concept differs from both, rule understanding and rationality. We then turn to...
