This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

I consider a model in which an asset owner must decide how much to invest in his asset mindful of the fact that an encroacher's valuation of the asset is increasing in the asset owner's investment. Due to incomplete property rights, the encroacher and asset owner engage in a contest over the...

The present paper analyzes situations in which groups compete for rents. A major result in the literature has been that there are both cases where larger groups have advantages and cases where they have disadvantages. The paper provides two intuitive criteria which for groups with homogenous...

We analyse how state university competition to collect resources may affect both research and the quality of teaching. By considering a set-up where two state universities behave strategically, we model their interaction with potential students as a sequential noncooperative game. We show that...

This paper investigates optimal contest design when the designer s payoff is increasing in competitive balance between contestants. A two-player contest with asymmetric effort costs (asymmetric abilities) is considered. Competitive balance is measured by the difference in winning probabilities...

Altruists and envious people who meet in contests are symbionts. They do better than a population of narrowly rational individuals. If there are only altruists and envious individuals, a particular mixture of altruists and envious individuals is evolutionarily stable.

Economic policy is modeled as the outcome of a (political) game between two inte rest groups. The possible ex-post (realized) outcomes in the game correspond to the proposed policies. In the literature the policies fought for are exogenous. We extend such games by allowing the endogenous...
