The rapid spread of the COVID-19 pandemic and subsequent countermeasures, such as school closures, the shift to working from home, and social distancing are disrupting economic activity around the world. As with other major economic shocks, there are winners and losers, leading to increased...

The recruitment of foreign scientists enhances US science through an expanded workforce but could also cause harm by displacing better connected domestic scientists, thereby reducing localized knowledge spillovers. We develop a model in which a sufficient condition for the absence of overall...

Crowdfunding may provide much-needed financial resources, yet there is little systematic evidence on the potential of crowdfunding for scientific research. We first briefly review prior research on crowdfunding and give an overview of dedicated platforms for crowdfunding research. We then...

We study a dynamic model of the decision to continue or abandon a research project. Researchers improve their ideas over time and also learn whether those ideas will be adopted by the scientific community. Projects are abandoned as researchers grow more pessimistic about their chance of success....

We summarize existing empirical findings regarding the adoption of robotics and AI and its effects on aggregated labor and productivity, and argue for more systematic collection of the use of these technologies at the firm level. Existing empirical work primarily uses statistics aggregated by...

Police use of force - particularly lethal force - is one of the most divisive issues of the twenty-first century. To understand the nexus of race, criminal justice, and police brutality, academics and journalists have begun to amass impressive datasets on Officer-Involved-Shootings (OIS). I...

Precision medicines - therapies that rely on the use of genetic, epigenetic, and protein biomarkers - create a better match between patients with specific disease subtypes and medications that are more effective for those patients. This heterogeneity in response has implications for the decision...

In many growth models, economic growth arises from people creating ideas, and the long-run growth rate is the product of two terms: the effective number of researchers and their research productivity. We present a wide range of evidence from various industries, products, and firms showing that...

Alfred Marshall and Mary Paley Marshall are often described as the first academic economist couple. Both studied at Cambridge University, where Paley became one of the first women to take the Tripos exam and the first female lecturer in economics, with Marshall's encouragement. But in later...

We develop a model of large multinational enterprises, each one producing a continuum of products. These outsized firms compete as oligopolists in a domestic and foreign market, facing competitive pressure from single-product firms that engage in monopolistic competition. The multinational...
