We present a model where each of two players chooses between remuneration based on either private or team effort. Although at least one of the players has the equilibrium strategy to choose private remuneration, we frequently observe both players to choose team remuneration in a series of...

Für die einen gilt: "Nur Warnhinweise auf Lebensmitteln können vor der Volksseuche Übergewicht noch retten." Für die anderen hingegen ist klar: "Eine rote Ampel auf kalorienreichen Lebensmitteln bedeutet eine unerträgliche Entmündigung der Bürger." Die aktuelle Kontroverse um die von der...

In a series of experimental games, each of two players may choose between remuneration based on either private or team effort. Although at least one of the players has the subgame perfect equilibrium strategy to choose remuneration based on private effort, we frequently observe team remuneration...

Since Mancur Olson’s “Logic of collective action” it is common conviction in social sciences that in large groups the prospects of a successful organization of collective actions are rather bad. Following Olson’s logic, the impact of an individual’s costly contribution becomes smaller...

We introduce a simple game-theoretical model that captures the main aspects of the repeated interaction between an issuer and a credit rating agency. The scenario is characterized by up-front payments of issuer-fees and regulatory sanctions for false rating. We chose parameters such that in the...

In an experimental 2x2 coordination game with two strict equilibria we observe that, in contrast to equilibrium selection theory (Harsanyi and Selten 1988), only half of the subjects choose the strategy that relates to the payoff- and risk-dominant equilibrium. We propose modified risk dominance...
