This paper studies the design of optimal contracts in dynamic environments where agents learn by doing. We derive a condition under which contracts are fully incentive compatible. A closed-form solution is obtained when agents have CARA utility. It shows that human capital accumulation...

The existing delegation literature has focused on different preferences of principal and agent concerning project selection, which makes delegating authority costly for the principal. This paper shows that delegation has a cost even when the preferences of principal and agent are exogenously...

We develop a new approach to quantify how patients respond to dynamic incentives in health insurance contracts with a deductible. Our approach exploits two sources of variation in a differences-in-regression-discontinuities design: deductible contracts reset at the beginning of the year, and...

Consider a principal-agent relationship in which more effort by the agent raises the likelihood of success. Does rewarding success, i.e., paying a bonus, increase effort in this case? I find that bonuses have not only an incentive but also an income effect. Overall, bonuses paid for success may...

We consider an economy where individuals privately choose effort and trade competitively priced securities that pay off with effort-determined probability. We show that if insurance against a negative shock is sufficiently incomplete, then standard functional form restrictions ensure that...

We develop a model of strategic contractual incompleteness that identifies conditions under which principals might omit even costlessly verifiable terms. We then use experiments to test comparative statics predictions of the model. While it is well known that verifiability imperfections can...

We investigate how payoff-irrelevant terms can negatively impact relational contracts. In a lab experiment we compare two economically equivalent contracts - a fixed-term renewable and an open-ended at-will contract. Each contract provides partners with full flexibility regarding the length and...

This paper offers a rationale for limiting the delegation of (real) authority, which neither relies on insurance arguments nor depends on ownership structure. We analyse a repeated hidden action model in which the actions of a risk neutral agent determine his future outside option. Consequently,...

Severance pay, a fixed-sum payment to workers at job separation, has been the focus of intense policy concern for the last several decades, but much of this concern is unearned. The design of the ideal separation package is outlined and severance pay emerges as a natural component of job...

We develop a stylized principal-agent model with moral hazard and adverse selection to provide a unified framework for understanding some of the most salient features of the recent physician payment reform in Ontario and its impact on physician behavior. These features include: (1) physicians...
