This paper studies the ability of an agent and a principal to achieve the first-best outcome when the agent invests in an asset that has greater value if owned by the principal than by the agent. When contracts can be renegotiated, a well-known danger is that the principal can holdup the agent,...

In games with strict strategic complementarities, properly mixed Nash equilibria--equilibria that are not in pure strategies--are unstable for a broad class of learning dynamics.

Predation occurs when a firm offers consumers favorable deals, usually in the short run, that get rid of competition and thereby harm consumers in the long run. Modern economic theory has shown how commitment or collective-action problems among consumers can lead to such paradoxical effects. But...

We estimate auto accident externalities (more specifically insurance externalities) using panel data on state-average insurance premiums and loss costs. Externalities appear to be substantial in traffic dense states: in California, for example, we find that a typical additional driver increases...

Americans drive 2,360,000,000,000 miles each year, far outstripping other nations. Every time a driver takes to the road, and with each mile she drives, she exposes herself and others to the risk of accident. Insurance premiums are only weakly linked to mileage, however and have largely lump-sum...

Several recent papers argue that price matching policies raise equilibrium prices. We add to this literature by considering potential welfare losses, which have two sources: Harberger triangles from high prices and Posner rectangles from over-entry. We compare markets with price matching and...

Contract law's liquidated damage rules prevent enforcement of contractual damage measures that require the promisor, if it breaches, to transfer to the promisee a sum that exceeds the net gain the promisee expected to make from performance; but these rules permit the promisor to transfer less than...

Most insurance premiums are only weakly linked to mileage, and have largely lump-sum characteristics. The probable result is too many accidents and too much driving from the standpoint of economic efficiency. This paper develops a model of the relationship between driving and accidents that...

This paper shows how fixed costs can play an important role in determining the structure of organizations. Applications considered include layoffs, downsizing, heterogeneity among firms, and the structure of hierarchies. Agency problems as a source of fixed costs are also considered.

Previous empirical analyses of the relationship between executive compensation and firm performance are often interpreted as suggesting that this relationship is weak. Although an absolute term like "weak" is ambiguous in this context, relative terms, such as "stronger," are meaningful. We argue...
