We study how people's predisposition towards altruism affects their behavior in a voluntary contributions public good experiment. We investigate whether a high level of contributions can be sustained in groups of subjects who have been pre-selected on the basis of their altruistic inclinations....

We extend the finite automata approach to evaluate complexity of strategies in iterative adjustment processes such as auctions. Intuitively, a strategy's complexity is equal to the number of different contingencies in which qualitatively different behaviors are prescribed. Complexity may explain...
