On a heterogeneous experimental oligopoly market, sellers choose a price, specify a set-valued prior-free conjecture about the others' behavior, and form their own profit-aspiration for each element of their conjecture. We formally define the concepts of satisficing and prior-free optimality and...

The satisficing approach is generalized and applied to finite n-person games. Based on direct elicitation of aspirations, we formally define the concept of satisficing, which does not exclude (prior-free) optimality but includes it as a border case. We also review some experiments on strategic...

Almost all international environmental agreements include a minimum participation rule. Under such a rule an agreement becomes legally binding if and only if a certain threshold in terms of membership or contribution is reached. We analyze a cartel game with open membership and heterogeneous...

The environmental discussion is increasingly extended to the question of how to preserve biodiversity. As sensible regulation of biodiversity utilization uses politically set incentive schemes, it is required to discus the monetary value of biodiversity. Consequently, the relation between...
