We consider a principal-agent model in which the agent needs to raise capital from the principal to finance a project. Our model is based on DeMarzo and Fishman (2003), except that the agent's cash flows are given by a Brownian motion with drift in continuous time. The difficulty in writing an...

We study investment options in a dynamic agency model. Moral hazard creates an option to wait and agency conflicts affect the timing of investment. The model sheds light, theoretically and quantitatively, on the evolution of firms' dynamics, in particular the decline of the failure rate and the...

We study optimal compensation in a fully dynamic framework where the CEO consumes in multiple periods, can undo the contract by privately saving, and can temporarily inflate earnings. We obtain a simple closed-form contract that yields clear predictions for how the level and...

We show that it is impossible to achieve collusion in a duopoly when (1) the prices depend only on the sum of the firms' supplies (2) firms are able to respond to new information quickly and (3) the likelihood ratio for detection of each deviation is a continuous process (so that new information...

We study a continuous-time reputation game between a large player and a population of small players in which the actions of the large player are imperfectly observable. We explore two versions of the game. In the complete information game, in which it is common knowledge that the large player is...

This paper develops a dynamic two-country neoclassical stochastic growth model with incomplete markets. Short-term credit flows can be excessive and reverse suddenly. The equilibrium outcome is constrained inefficient due to pecuniary externalities. First, an undercapitalized country borrows too...

This paper studies the full equilibrium dynamics of an economy with financial frictions. Due to highly non-linear amplication effects, the economy is prone to instability and occasionally enters volatile episodes. Risk is endogenous and asset price correlations are high in downturns. In an...

This paper provides a theory of money, whose value depends on the functioning of the intermediary sector, and a unified framework for analyzing the interaction between price and financial stability. Households that happen to be productive in this period finance their capital purchases with...
