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...

We compare how children aged 9-12 in Colombia and Sweden cooperate in a Prisoner's Dilemma. We introduce a new measurement device for cooperation that can be easily understood by children. There is some evidence of more cooperation in Sweden than in Colombia. Girls in Colombia are less...

We look at gender differences in preferences for altruism, risk and competition in math and word search among adolescents in Sweden. We find that girls are more altruistic and less risk taking than boys. We find no gender gap in performance change when comparing performance under non-competition...

Many previous experiments document that behavior in multi-person settings responds to the name of the game and the labeling of strategies. Usually these studies cannot tell whether frames affect preferences or beliefs. In this Dictator game study, we investigate whether social framing effects...

We rigorously test for ethnic discrimination in high school grading in Sweden. A random sample of the national tests in the Swedish language is graded both non-blind by the student's own teacher and blind without any identifying information. The increase in the test score due to non-blind...

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;...

This paper presents an infinite-horizon version of intergenerational utilitarianism that is both satisfactorily complete and consistent. By studying discounted utilitarianism as the discount factor tends to one, we obtain a welfare criterion - limit-discounted utilitarianism - that combines...

A hierarchically structured rent-seeking contest may be associated with lower equilibrium expenditure than a corresponding flat contest. In this chapter we discuss how this fact may be used to explain the structure of organizations such as firms, including why firms commonly have outside owners.

This paper provides axiomatic descriptions of social welfare relations, defined on infinite streams of utility, that are consistent with the utilitarian criterion on subsets where maximizing aggregate utility has a clear interpretation: the streams, or their differences, are summable. Besides...

This paper presents an infinite-horizon version of intergenerational utilitarianism. By studying discounted utilitarianism as the discount factor tends to one, we obtain a welfare criterion --- limit-discounted utilitarianism (LDU) --- that is analytically tractable, respects the Pareto order,...
