In this paper, we consider a dynamic signaling model of an R&D market in which a researcher can choose either a safe project (exploitation) or a risky project (exploration) at each instance. We argue that there are substantial efficiency gains from rewarding minor innovations above their social...

This paper examines the interplay between career concerns and market structure. Ability and effort are complements: effort increases the probability that a skilled agent achieves a one-time breakthrough. Wages are based on assessed ability and on expected output. Effort levels at different times...

Both psychologists and economists have argued that rewards often have hidden costs. One possible reason is that the principal may have incentives to offer higher rewards when she knows the task to be difficult. Our experiment tests if high rewards embody such bad news and if this is perceived by...

We analyze a dynamic principal-agent problem with moral hazard and private learning. Each period the agent faces a choice between two actions: a safe action with known returns (exploitation) and a costly risky action with unknown returns (experimentation). We explicitly characterize the cheapest...

Employees often learn about their ability while working, and the resulting beliefs interact with pay incentives to shape employment outcomes. This paper investigates this issue within a model that incorporates learning about ability on the job, dynamic selection, effort, and variation in pay...

Principals seek to enter into a productive relationship with agents by posting mechanisms in a market with competitive search. A mechanism includes an incentive contract if the meeting is bilateral, and an ex post bidding process, in which agents make contract offers, if several agents meet the...

Principals seek to trade with agents by posting incentive contracts in a search environment. A contract solves the ex ante search problem, and adverse selection and moral hazard ex post. We fully characterise the equilibrium for quasi linear preferences, and derive some comparative statics. If...

Preregistering study designs is broadly supported as improving scientific credibility but criticized for limiting the scope of what can be learned. The paper investigates this tradeoff in a model where a researcher conducts a study and aims to convince an evaluator that the results are worth...

This paper analyzes the impact of market structure on career concerns. Effort increases the probability that a skilled agent achieves a one-time breakthrough. Wages are based on assessed ability and on expected output. For any wage, the agent works too little, too late. Under short-term...
