Evolutionary game theory is often used to analyze the evolution of moral preferences. A few studies also examine the coevolution of preferences and an institutional aspect of the decision environment. Allowing the adaptation of just one institutional aspect such as litigation or legal insurance...

Similar to Levati and Neugebauer (2001), a clock is used by which participants can vary their individual contributions for voluntarily providing a public good. As time goes by, participants either in(de)crease their contribution gradually or keep it constant. Groups of two poorly and two richly...

In this paper we study information revelation on asset markets with endogenous and exogenous information. Our results indicate that superior information can only be exploited in the beginning of trading. Information disseminates on the market and informational advantages are counter-balanced...

This experimental study investigates whether individuals prefer bounded rationality over rational choice theory when facing simple investment tasks. First, participants state some personal parameters that serve as an input to render a theoretical approach, namely satisficing or optimality,...

We study the behavior of football (soccer) referees in the German Bundesliga. Referees are requested to act as impartial agents. However, they may be tempted to allocate benefits and rewards in a biased way. Agency theory has long neglected this form of malfeasance of economic agents, but has...

The indirect evolutionary approach integrates forward-looking evaluation of opportunities and adaptation in the light of the past. Subjective motivation determines behavior, but long-run evolutionary success of motivational types depends on objective factors only, what can justify intrinsic...

Direct democracy with its use of referenda avoids the prototypical principal-agent problems of delegation in indirect democracies, especially since elected representatives are usually not committed by law to keep their promises. Sequential or more complex referenda may, however, result in an...

Hegemony is a central feature of contemporary international politics but it remains seriously under-theorized. We draw on cooperative game theory to represent and analyze different aspects of hegemony. After developing a general conception of hegemony, we analyze the circumstances under which a...

This paper investigates market failures due to strategic delays. We test experimentally a discrete model of dynamic investment, where two privately informed agents have an option to invest at the time of their choice in the presence of waiting costs. The equilibrium outcome of our experimental...

This paper revisits and extends the experiment on the solidarity game by Selten and Ockenfels (1998). We replicate the basic design of the solidarity game and extend it in order to t test the robustness of the ‘fixed total sacrifice’ effect and the applied strategy method. Our results only...
