The financial crisis of 2007-08 has underscored the importance of adverse selection in financial markets. This friction has been mostly neglected by macroeconomic models of financial frictions, however, which have focused almost exclusively on the effects of limited pledgeability. In this paper,...

A seller dynamically sells a divisible good to a buyer. It is common knowledge that there are gains from trade and that the gains per unit are decreasing. Payoffs are interdependent as in Akerlof's market for lemons. The seller is informed about the good's quality. The buyer makes an offer in...

We study dynamic contracting with adverse selection and limited commitment. A firm (the principal) and a worker (the agent) interact for potentially infinitely many periods. The worker is privately informed about his productivity and the firm can only commit to short-term contracts. The ratchet...

We study the relative performance of disclosure and auditing in organizations. We consider the information transmission problem between two decision makers who take actions at dates 1 and 2 respectively. The first decision maker has private information about a state of nature that is relevant...

We examine the buyer-seller problem under different levels of commitment. The seller is informed of the quality of the good, which affects both his cost and the buyer's valuation, but the buyer is not. We characterize the allocations that can be achieved through mechanisms in which, unlike with...

This paper analyzes the optimal provision of incentives in a sequential testing context. In every period the agent can acquire costly information that is relevant to the principal's decision. Neither the agent's effort nor the realizations of his signals are observable. First, we assume that the...

Institutions designed to increase turnout appeal to democratic sentiments but are highly debated as they entail two potentially countervailing effects. While generating more pieces of information, they may decrease the average voter's information quality. We examine two commonly discussed...

This paper shows that private information may be crucial in explaining the relationship between liquidity, investment and economic fluctuations. First, it defines liquidity in a way that is clearly connected to investment and output. Second, it models economies where privately informed...

The existence of collateral requirements to guarantee repayment on issued securities reduces in general the efficiency of competitive equilibria. The general equilibrium analysis is presented in a world where reputation plays no role, and the lender always expects a future payment equal to the...

A small number of countries have issued real indexed sovereign debt in recent year. This type of contracts could improve risk sharing between debtor countries and international creditors and diminish the probability of occurrence of debt crises. However, it is not clear the magnitude of these...
