We analyse a simple model of dynamic moral hazard in which there is a clear and tractable trade-off between static and dynamic incentives. In our model, a principal wants an agent to complete a project. The agent undertakes unobservable effort, which affects in each period the probability that...

We analyse a simple model of dynamic moral hazard in which there is a clear and tractable trade-off; between static and dynamic incentives. In our model, a principal wants an agent to complete a project. The agent undertakes unobservable effort, which affects in each period the probability that...

I construct an equilibrium model of the labor market where workers and firms enter into dyamic contracts that can potentially last forever, but are subject to optimal terminations.  Upon a termination, the firm hires a new worker, and the worker who is terminated receives a termination...

We study the agency problem between a firm and its research employees. In a multi-agent contracting setting, we show explicitly the way in which the optimal incentive regime is a function of how agents' efforts interact with one another: relative-performance evaluation is used when their efforts...

This paper investigates how a buyer and a seller exchanging two goods should write the contract, where the seller makes sequences of unobservable relation-specific investments and the buyer privately learns valuations for goods which are stochastically influenced by the investments and these two...

This paper studies repeated moral hazard in teams. Agents' actions are observable to each other but not to the principal. For any given dynamic contract, agents always select their favorite subgame perfect equilibrium in the corresponding dynamic game. The optimal dynamic contract must take that...

An advocate for a special interest provides information to an uninformed planner for her to consider in making a sequence of important decisions. Although the advocate may have valuable information for the planner, it is is also known that the advocate is biased and will distort her advice if...

A generalization of the continuous time mutual fund theorem is given, with no assumptions made on the investors utility functions for consumption and final wealth, except that they are time-additive and non-decreasing. The extension is due to a new mathematical approach, using no more than...

Few textbooks in mathematical economics cover optimal timing problems. Those which cover them do it scantly or in a rather clumsy way, making it hard for students to understand and apply the concept of optimal time in new contexts. Discussing the plentiful illustrations of optimal timing...
