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...

Our results paint a complex picture of academic and industrial science. While we find significant industry-academia differences with respect to all four dimensions, we also observe remarkable similarities. For example, both academic institutions and private firms appear to allow their scientists...

For decades, the US public and private sectors have committed substantial resources towards cancer research, but the societal payoff has not been well-understood. We quantify the value of recent gains in cancer survival, and analyze the distribution of value among various stakeholders. Between...
