We develop an evolutionary approach to explain altruistic preferences. Given their preferences, individuals interact rationally with each other. By comparing the success of players with different preferences, we investigate whether evolution favors altruistic or selfish attitudes. The outcome...

Suppose two parties have to share a surplus of random size.Each of the two can either commit to a demand prior to the realization of the surplus - as in the Nash demand game with noise - or remain silent and wait until the surplus was publicly observed.Adding the strategy to wait to the noisy...

In a three player dynamic public goods experiment, social output today determines production possibilities tomorrow.In each period, players choose to sabotage, to co-operate, or to play best response.Sabotage harms social output and growth.Mutual co-operation maximises both.The property rights...

In an experimental study we examine a variant of the 'minimum effort game', a coordination game with Pareto ranked equilibria, and risk considerations pointing to the least efficient equilibrium.We focus on the question whether simple cues such as smiles, winks and handshakes could be recognized...

Abstract: Lindelauf et al. (2009a) introduced a quantitative approach to investigate optimal structures of covert networks. This approach used an objective function which is based on the secrecy versus information trade-off these organizations face. Sageman (2008) hypothesized that covert...
