We demonstrate that a multi-period model, and the valuations it implies, is essential for understanding inefficiency in cooperative organizational forms. Investment is efficient given the supply of input, but economic inefficiency arises because of over-supply of input induced by suppliers...

We develop a two-period model where a risk-averse entrepreneur decides on the size of an investment project and how to finance it. He can use debt and/or equity finance; an incentive compatibility constraint limits the extent to which the project can be financed with equity. With debt, he may, in...

The paper develops a theory of ownership structure based on the notion that corporate control and secondary market liquidity are not perfectly compatible with eath other. We analyze the tradeoff between these two objectives for two different ownership structures: the privately held firm, which...

We analyze the incentives for a controlling shareholder to acquire silent or controlling shares in a competitor. When it occurs, the acquisition is detrimental to minority shareholders of his firm, or to the target, or even to both. The ownership structure of firms turns out to be a key...

This paper presents a two-period model of talent investments in which two clubs compete for a contest prize. We show that multiple equilibria are possible, using a closed-loop approach with strictly convex costs: The large-market club invests in both periods more than the small-market club or...

Based on a Hotelling-type model, this paper analyzes a differential game where two firms engage in quality-enhancing research and development (R&D). The analysis is formulated in terms of open-loop and feedback solutions. We find that the open-loop stationary levels of R&D and quality are...

This paper analyzes a dynamic moral hazard problem in which the agent's unobservable effort in each period affects both current and future cash flows. For incentive contracting purposes, the principal can rely on realized and projected future cash flows. We find that a properly structured...

In the context of public-good provision, despite noncontractibility of investments, it is possible to specify who is in charge of tasks such as construction and maintenance. We show that complementarity between the investments of the two tasks favors unbundling of tasks through different...

The paper uses the findings of psychology, behavioral economics, and behavioral ethics to revisit three main related assumptions of the rational-choice approach to equity, by developing three main points: first, not only bad people try to circumvent the law; second, behavior depends on the...

We consider the transitions among intragenerational and alternative intergenerational financing and liquidity risk sharing mechanisms, in an overlapping generations model with endogenous levels of long-lived investments. The existence and characterization of a self-sustaining mechanism, stable...
