We present a mechanism based on managerial incentives through which common ownership affects product market outcomes. Firm-level variation in common ownership causes variation in managerial incentives and productivity across firms, which leads to intra-industry and intra-firm cross-market...

Team incentives are important in many compensation systems that pay workers according to the output of their team as well as to their own output, with team bonuses often depending on whether the team meets or exceeds specified thresholds. Yet little is known about how team members with different...

We develop a model of human interaction to analyze the relationship between globalization and pandemics. Our framework provides joint microfoundations for the gravity equation for international trade and the Susceptible-Infected-Recovered (SIR) model of disease dynamics. We show that there are...

We develop an ECON-EPI network model to evaluate policies designed to improve health and economic outcomes during a pandemic. Relative to the standard epidemiological SIR set-up, we explicitly model social contacts among individuals and allow for heterogeneity in their number and stability. In...

In response to the Covid-19 pandemic, many localities instituted non-essential business closure orders, keeping individuals categorized as essential workers at the frontlines while sending their non-essential counterparts home. We examine the extent to which being designated as an essential or...

We study learning via shared news. Each period agents receive the same quantity and quality of first-hand information and can share it with friends. Some friends (possibly few) share selectively, generating heterogeneous news diets across agents akin to echo chambers. Agents are aware of...

The college experience involves much more than credit hours and degrees. Students likely derive utility from in-person instruction and on-campus social activities. Quantitative measures of the value of these individual components have been hard to come by. Leveraging the COVID-19 shock, we...

Racial social isolation within and across workplaces may reduce firm productivity. We provide descriptive evidence that African-Americans feel socially isolated from Whites. To test whether isolation affects productivity, we estimate models of Total Factor Productivity for manufacturing firms...

Using friendship data from Facebook, we study the effects of three aspects of social capital on household financial behavior. We find that the most important measure of social capital in explaining stock market and saving participation is Economic Connectedness, defined as the fraction of one's...

We examine the combined effects of popularity and feelings of being important to reaching a goal by testing how people react to situations in which their own behavior is pivotal or not, as well as the popularity of the action. We conduct a laboratory experiment to cleanly fix beliefs about the...
