This paper studies a general equilibrium model with two groups of agents, investors (shareholders) and managers of firms, in which managerial effort is not observable and influences the probabilities of firms’ outcomes. Shareholders of each firm offer the manager an incentive contract which...

This paper studies the equilibria of a stochastic OLG exchange economies consisting of identical agents living for two periods, and having the opportunity to trade a single infinitely-lived asset in constant supply. The agents have uncertain endowments and the stochastic process determining the...

Economists have long argued that loan contracts should be indexed to remove the risks arising from fluctuations in the purchasing power of money: indexation however while eliminating one risk, substitutes another, arising from fluctuations in relative prices of goods. We present a theoretical...

This paper derives the equilibrium of an infinite-horizon discrete-time CAPM economy in which agents have discounted expected quadratic utility functions. We show that there is an income stream obtainable by trading on the financial markets which best approximates perfect consumption smoothing...

Economists hold two opposing views of the stock market: one focuses on the negative effect on incentives of separating ownership and control, the other emphasizes its beneficial role for risk sharing. Using a generalization of Diamond's model which incorporates the effect of entrepreneurial...

A stock market is a mechanism by which the ownership and control of firms is determined through the trading of securities. It is on this market that many of the major risks faced by society are shared through the exchange of securities and the production decisions that influence the present and...

This paper studies a simple OLG model with production under the assumption that capital investment is completely irreversible: installed capital cannot be transformed back into consumption good nor transferred from one firm to another. Since firms cannot be dismantled at each generational change...

Economists have long argued that loan contracts should be indexed to remove the risks arising from fluctuations in the purchasing power of money: indexation however while eliminating one risk, sustitutes another, arising from fluctuations in relative prices of goods. We present a theoretical...

In a general equilibrium model with money we show that anticipated changes in monetary policy have real effects if markets are incomplete and have no real effects if markets are complete. Unanticipated changes in monetary policy always have real effects.
