In this paper we study price competition, equilibrium market configurations and entry when firms compete in vertically-di¤erentiated markets producing complementary goods. We consider two complements and start from a configuration where the market for one complement is a duopoly, whereas the...

In this paper, we study a two-stage rent-seeking game. In the first stage, contestants compete a-la-Tullock; in the second stage, the winner can resell the rent a-la-Coase. We consider a complete information Tullock game in which the contestants have different valuations for the rent. The...

The presence of multiple sellers in the provision of (nonsubstitutable) complementary goods leads to outcomes that are worse than those generated by a monopoly (with a vertically integrated production of complements), a problem known in the economic literature as complementary oligopoly and...

In this paper we revisit Tullock's (1980) paradox and consider a rent-seeking game in which parties face increasing returns to effort. We allow parties to randomize their strategies and give them an exit option. Given the mixed participation strategies of the parties, valuable rents may...

The presence of multiple sellers in the provision of (non-substitutable) complementary goods leads to outcomes that are worse than those generated by a monopoly (with a vertically integrated production of complements), a problem known in the economic literature as complementary oligopoly and...

This paper presents a general rent-seeking model in which participants decide on entry before choosing their levels of efforts. The conventional wisdom in the rent-seeking literature suggests that the rent dissipation increases with the number of potential participants and with their...

In the traditional formulation of rent-seeking games, increasing returns to effort are characterized by an exponent r 1. However,when the value of rent is normalized to 1, the players’ effort levels A and B will typically be less than 1. Thus, when A < 1 and r > 1, the value of Ar decreases as r...</1>

In this paper, we study the effects and desirability of legal rules that allow the sharing of an accident loss between a non-negligent injurer and his non-negligent victim. In order to identify the virtues and limits of loss-sharing rules, we begin by considering the effect of a loss-sharing...

In rent-seeking contests, players are seldom identical to one another. In this chapter, we examine the rent-seeking literature that explores the effects of specific forms of asymmetry between contestants. We consider Tullock's rent-seeking contests involving two players who differ in strength...

The analysis of tort law is one of the most well-developed applications of economic methodology in the study of law. In this essay, we provide an overview of the economic approach to tort law, analyzing the effects of liability rules on care incentives. We catalogue a variety of possible tort...
