The marginal cost of effort often increases as effort is exerted. In a dynamic moral hazard setting, dynamically increasing costs create information asymmetry. This paper characterizes the optimal contract and helps explain the popular yet thus far puzzling use of non-linear incentives, for...

We consider a double-sided moral hazard problem where each party can renege on the signed contract since there does not exist any verifiable performance signal. It is shown that ex-post litigation can restore incentives of the agent. Moreover, when the litigation can be settled by the parties...

We examine optimal managerial compensation and turnover policy in a principal-agent model in which the firm output is serially correlated over time. The model captures a learning-by-doing feature: higher effort by the manager increases the quality of the match between the firm and the manager in...

We study a setting in which one or two agents conduct research on behalf of a principal. The agents' success depends on effort and the choice of a research technology that is uncertain with respect to its quality. A single agent has no incentive to deviate from the principal's preferred...

Deadlines and penalties are widely used to incentivize effort. We model how these incentive contracts affect the work rate and time taken in a procurement setting, characterizing the efficient contract design. Using new micro-level data on Minnesota highway construction contracts that includes...

This paper studies the optimal contract for a risk-neutral agency with limited liability. We introduce a novel formulation of the model, in which the contract design problem reduces to a problem of constructing the distribution function of a random variable. This formulation directly balances...

This study investigates the optimal incentive structure for a government procurement contract in the field of defense. Optimality implies that the government achieves efficient and cost-effective procurement through incentives that encourage the contracting firm to reduce costs in the presence...

In this paper, we show that whenever the agent's outside option is nonzero, the optimal contract in the continuous-time principal-agent model of Sannikov (2008) is reflective at the lower bound. This means the agent is never terminated or retired after poor performance. Instead, the agent is...

We show that contracting in agency with voluntary participation may involve incentives for the agent's abstention. Their provision alters the optimality criteria in the principal's decision-making, further distorts the mechanism, and may lead to breakdown of contracting in circumstances where...

This paper analyzes relational contracts under moral hazard. We first show that if the available information (signal) about effort satisfies a generalized monotone likelihood ratio property, then irrespective of whether the first-order approach (FOA) is valid or not, the optimal bonus scheme...
