In this paper, I consider the problem of designing an optimal screening contract for a principal facing an agent whose type comes as a sequence that unfolds through time. Formally, the agent has a private ex ante type that stands for the expected value of his private ex post type. Under full...

I study a problem of repeated moral hazard in which the effect of effort is persistent over time: each period's outcome distribution is a function of a geometrically distributed lag of past efforts. I show that when the utility of the agent is linear in effort, a simple rearrangement of terms in...

We study a multiperiod principal-agent problem with moral hazard in which effort is persistent: the agent is required to exert effort only in the initial period of the contract, and this effort determines the conditional distribution of output in the following periods. We provide a...

We study optimal incentives in a principal-agent problem in which the agent's outside option is determined endogenously in a competitive labor market. In equilibrium, strong performance increases the agent's market value. When this value becomes sufficiently high, the threat of the agent's...

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...

I study firm characteristics that justify the use of options or refresher grants in the optimal compensation packages for CEOs in the presence of moral hazard. I model explicitly the determination of stock prices as a function of the output realizations of the firm: Symmetric learning by all...

Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. An efficient risk classification system generates premiums that fully reflect the...

This paper presents a static model of a market for a quality-differentiated good. In one version quality is observable, in the other it is not. It is shown that some agents who are uninformed when quality is unobservable may have higher utility than they do when it is observable. This is more...

Official development assistance (grants and subsidized loans from foreign aid agencies) is the main source of external finance in developing countries. These financial aid flows are positively correlated with the recipients' business cycles, which is puzzling because it reinforces already strong...

Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. With perfect risk classification, premiums fully reflect the expected cost associated...
