In this paper I consider the desirability of drugs that enhance cognitive abilities in the context of tournaments that are used as optimal labor contracts as in Lazear and Rosen (1981). Such drugs reduce the number of voluntary participants in a tournament, but increase individual and total...

We study equilibrium in a multistage race in which players compete in a sequence of simultaneous move component contests. Players may win a prize for winning each component contest, as well as a prize for winning the overall race. Each component contest is an all-pay auction with complete...

We characterize the unique Markov perfect equilibrium of a tug-of-war without exogenous noise, in which players have the opportunity to engage in a sequence of battles in an attempt to win the war. Each battle is an all-pay auction in which the player expending the greater resources wins. In...

In general equilibrium, with complete conventional securities markets and endogenous asset supply, taxes on risk remuneration are ineffective but harmless. They do not alter the real allocation of goods or the distribution of wealth, they impose no excess burden, and, in particular, have no...

This paper studies the comparative statics of self-insurance and self-protection for individuals with rank-dependent expected utility preferences. In particular, proportional wealth risks, background risk, and limited liability are considered. Limited liability has a major impact on...

A firm which lobbies government for a change in policy, say an import tariff, can increase its profits in two ways. First, the policy can increase the profits of all firms in the industry. This effect therefore involves a free-rider problem. Second, a firm's lobbying expenditures may signal...

Countries compete for new FDI investment, whereas stocks of FDI generate agglomeration benefits and are potentially subject to extortionary taxation. We study the interaction between these aspects in a simple vintage capital framework with discrete time and an infinite horizon, focussing on...

Income disparities and the intra-family redistribution implied by a marriage may induce a high-income earner to abstain from marrying a low-income earner even though they would be a perfect match emotionally. Redistributive income taxation eases this problem, and the design of marriage matching...

If firms compete in all-pay auctions with complete information, silent shareholdings introduce asymmetric externalities into the allpay auction framework. If the strongest firm owns a large share in the second strongest firm, this may make the strongest firm abstain from bidding. As a...

Incomplete information is a commitment device for time consistency problems. In the contextof time consistent labor income taxation privacy can lead to a Pareto superior outcome and increases the effectiveness of public education as a second best policy.
