We interpret the psychology literature on social identity and examine its implications in a population partially composed of such agents. We model a population of agents from two exogenous and well defined social groups. Agents are randomly matched to play a reduced form bargaining game. We show...

In this paper we consider the interaction between local workers and migrants in the production process of a firm. Both local workers and migrants can invest effort in assimilation activities in order to increase the assimilation of the migrants into the firm and so by increase their interaction...

Ethnic networks are a way of overcoming informal barriers to trade such as information costs, risk, and uncertainty by building trust and by substituting for the difficulty of enforcing contracts internationally. We study networks which emerge from the interaction (i) between migrants and...

In the literature on optimal indemnity schedules, indemnities are usually restricted to be non-negative. Gollier (1987) shows that this constraint might well bind: insured could get higher expected utility if insurance contracts would allow payments from the insured to the insurer at some...

This paper studies a model of how political parties use resources for campaigning to inform voters. We show existence of equilibrium under mild assumptions for an arbitrary number of parties. The main result is that if the parties are more extreme, then they spend less resources on campaigning...

We study decentralized trade processes in general exchange economies and house allocation problems with and without money. Such processes are subject to persistent random shocks stemming from agents’ maximization of random utility. By imposing structure on the utility noise term —logit...

Several countries practice a system where laymen, who lack legal education, participate in the judicial decision making. Yet, little is known about their potential influence on the court rulings. In Sweden lay judges (namndeman) are affiliated with the political parties and appointed in...

Earlier studies on income inequality and crime have typically used total income or total earnings. However, it is quite likely that it is changes in permanent rather than in transitory income that affects crime rates. The purpose of this paper is therefore to disentangle the two effects by,...

We model the settlement of a legal dispute where the trial outcome depends on the behavior of a strategically motivated judge. We consider a standard asymmetric information model where the uninformed defendant makes a take it or leave it offer. If the case goes to trial, the judge decides how...
