We analyze a competitive labor market in which workers signal their productivities through education à la Spence (1973), and firms have the option of auditing to learn workers' productivities. Audits are costly and non–contractible. We characterize the trade–offs between signaling by...

Guaranteed renewability is a prominent feature in many health and life insurance markets. It is well established in the literature that, when there is (only) risk type uncertainty, the optimal GR contract with renewal price set at the actuarially fair price for low risk types provides full...

We analyze a repeated game in which countries are polluting as well as investing in technologies. While folk theorems point out that the first best can be sustained as a subgame-perfect equilibrium when the players are sufficiently patient, we derive the second best equilibrium when they are...

We analyze the optimal contract in static moral hazard situations, where the agent's effort is not verifiable. We first present the main trade-offs of the principal-agent model. We cover the trade-off of incentives (motivation) vs. risk-sharing (efficiency), incentives vs. rents (when the agent...

Several frictions restrict the government's ability to tax assets. First, it is very costly to monitor trades on international asset markets. Second, agents can resort to nonobservable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too high. This...

We explore how inherent preferences for reciprocity and repeated interaction interact in an optimal incentive system. Developing a theoretical model of a long-term employment relationship, we first show that reciprocal preferences are more important when an employee is close to retirement. At...

The assumption that payoff-relevant information is observable but not verifiable is important for many core results in contract, organizational and institutional economics. However, subgame-perfect implementation (SPI) mechanisms -- which are based on off-equilibrium arbitration clauses that...

Existing theories of a firm's optimal capital structure seem to fail in explaining why many healthy and profitable firms rely heavily on equity financing, even though benefits associated with debt (like tax shields) appear to be high and the bankruptcy risk low. This holds in particular for...

We analyze a relational contracting problem, in which the principal has private information about the future value of the relationship. In order to reduce bonus payments, the principal is tempted to claim that the value of the future relationship is lower than it actually is. To induce...

This paper reviews the theoretical and empirical literature on executive compensation. We start by presenting data on the level of CEO and other top executive pay over time and across firms, the changing composition of pay; and the strength of executive incentives. We compare pay in U.S. public...
