There is diverging empirical evidence on the competitive effects of horizontal mergers: consumer prices (and thus presumably competitors' profits) often rise while competitors' share prices fall. Our model of endogenous mergers provides a possible reconciliation. It is demonstrated that...

We provide a theoretical framework for understanding when an official angles for a bribe, when a client pays, and the payoffs to the client's decision. We test this framework using a new data set on bribery of Peruvian public officials by households. The theory predicts that bribery is more...

We use a sample of 133 countries to investigate the link between the abundance of natural resources and micro-economic reforms. Previous studies suggest that natural resource abundance gives rise to governments that are less accountable to the public, states that are oligarchic, and that it...

In this paper we study the adjustment of a N-country world economy to an unfavourable common supply shock. We show that world-wide monetary policy coordination is essential to achieve an optimal adjustment to the common shock, but that its actual implementation requires careful design to ensure...

This paper presents a rational expectations model of optimal executive compensation in a setting where managers are in a position to manipulate short-term stock prices, and managers' propensity to manipulate is uncertain. Stock-based incentives elicit not only productive effort, but also costly...

This Paper develops an argument explaining why retail prices may rise in response to the deregulation of opening hours. We make this point in a model of imperfect duopolistic competition. In a deregulated market retailers view the choice of opening hours as a means to increase the degree of...

We study how career concerns affect the dynamics of incentives in a multi-period contract, when the agent’s productivity is a stochastic function of his past productivity and investment. We show that incentives are stronger and performance is higher when the contract approaches its expiry...

The purpose of this Paper is to study the determinants of the concentration of ownership in a privatized, regulated firm. The discussion illustrates some aspects of the costs and benefits of different corporate systems. Privatized utilities are large firms with professional management: there is...

We examine whether stock market-listed firms in the U.S. invest suboptimally due to agency costs resulting from separation of ownership and control. We derive testable predictions to distinguish between underinvestment due to rational “short-termism” and overinvestment due to “empire...
