Kooperativní chování je nezbytnou podmínkou pro existenci moderních komplexních společenství a ekonomik, jak je známe dnes. Z pohledu společenských věd je proto zajímavé porozumnět, jak takové chování může převažovat i v situacích, kdy jednoduchá úvaha vede k opačnému...

One of the key assumptions of neoclassical economics is the existence of the rational individual, who always tries to maximize his or her utility. The paper shows possibilities of experimental evaluation of this hypothesis with respect to the various groups of people who undertake the...

We present a model of learning in which agents learn from errors. If an action turns out to be an error, the agent rejects not only that action but also neighboring actions. We find that, keepng memory of his errors, under mild assumptions an acceptable solution is asymptotically reached....
