We consider a basic stochastic evolutionary model with rare mutation and a best-reply (or better-reply) selection mechanism. Following Young's papers, we call a state stochastically stable if its long-term relative frequency of occurrence is bounded away from zero as the mutation rate decreases...

We prove that, in all finite generic extensive-form games of perfect information, a continuous-time best response dynamic always converges to a Nash equilibrium component. We show the robustness of convergence by an approximate best response dynamic: whatever the initial state and an allowed...

We propose a political theory for the slow adoption of technology in sports and other contests. We investigate players’preferences for new technology that improves contest accuracy. Modeling accuracy as the elasticity of "production" in a standard Tullock contest, we show that players may be...

This paper compares cooperation among Columbian and Swedish children aged 9-12. We illustrate the dynamics of the prisoner’s dilemma in a new task that is easily understood by children and performed during a physical education class. We find some evidence that children cooperate more in Sweden...

We look at gender differences among adolescents in Sweden in preferences for altruism, risk and competition. We find that girls are more altruistic and less risk taking than boys. No gender differences are found comparing competitive performance with non-competitive performance in either a...

In this paper I build a simplified model of the remuneration structure of a private equity fund using option theory. This model is then used to analyze the relative importance of the fixed and variable fee parts. The model is complemented with a structural model to evaluate the financial choices...

The folk theorems for infinitely repeated games with discounting presume that the discount rate between two successive periods is constant. Following the literature on quasi-exponential or hyperbolic discounting, I model the repeated interaction between two or more decision makers in a way that...

Social hierarchy is persistent in all almost all societies. Social norms and their enforcement are part of sustaining hierarchical systems. This paper combines social status and norm enforcement, by introducing status in a dictator game with third party punishment. Status is conveyed by surname;...

Personligheten är ett begrepp med rötter långt tillbaka i tiden och anses av många vara av stor betydelse, inte minst i arbetslivet. Personlighetstest har funnits och tillämpats i stor skala i snart 100 år. Den svenska marknaden för personlighetstestning omsätter 100-tals miljoner kronor...
