We analyze the design of legal principles and procedures for court decision-making in civil litigation. The objective is the provision of appropriate incentives for potential tort-feasors to exert care, when evidence about care is imperfect and may be distorted by the parties. Efficiency is...

This paper investigates how different damage rules in patent infringement cases shape competition when intellectual property rights are probabilistic. I develop a simple model of oligopolistic competition to compare two main liability doctrines that have been used in the US to assess...

We study the problem of multiple principals who want to obtain income from a privately informed agent and design their contracts non-cooperatively. Our analysis reveals that the degree of coordination between principals has strong implications for the shapes of contracts and the amount of...

The social and the private returns to education differ when education can increase productivity, and also be used to signal productivity. We show how instrumental variables can be used to separately identify and estimate the social and private returns to education within the employer learning...

What happens when employers would like to screen their employees but only observe a subset of output? We specify a model in which heterogeneous employees respond by producing more of the observed output at the expense of the unobserved output. Though this substitution distorts output in the...

A pre-condition for employer learning is that signals at labor market entry do not fully reveal graduates’ productivity. I model various distinct sources of signal imperfection—such as noise and multi-dimensional types—and characterize their implications for the private return to skill...

We study whether tweets about racial justice predict the offline behaviors of nearly 20,000 US academics. In an audit study, academics that tweet about racial justice discriminate more in favor of minority students than academics that do not tweet about racial justice. Racial justice tweets are...

Economists and management scholars have argued that the scope of incentives to increase cooperation in organizations is limited as their use signals the prevalence of free-riding among employees. This paper tests this hypothesis experimentally, using a sample of managers and employees from a...

In this paper, citizens vote in order to influence the election outcome and in order to signal their unobserved characteristics to others. The model is one of rational voting and generates the following predictions: (i) The paradox of not voting does not arise, because the benefit of voting does...
