How does a firm’s market power in existing products affect its incentives to innovate? We explore this fundamental question using granular project-level and firm-level data from the pharmaceutical industry, focusing on a particular mechanism through which incumbent firms maintain their market...

How do innovative firms react when existing products experience negative shocks? We explore this question with detailed project-level data from drug development firms. Using FDA Public Health Advisories as idiosyncratic negative shocks to approved drugs, we first examine how drug makers react...

This study examines the link between credit supply and hospital health outcomes. Using detailed data on hospitals and the banks that they borrow from, we use bank stress tests as exogenous shocks to credit access for hospitals that have lending relationships with tested banks. We find that...

We study dynamic Bayesian persuasion in an entry game. A sender publicly reveals information to an adopter and a competitor. When the sender's loss from competition is small, the optimal policy features hype cycles: the sender first exaggerates the value of a technology to attract the adopter,...

We study the environmental impact of green innovations by combining detailed firm-level toxic release data with patent-level measures of environmental technologies. To address the endogeneity concerns and measurement problems, we obtain patent-level exposures to the Green Technology Pilot...

We study venture capital finance with experimentation. An entrepreneur contracts with an investor and has private information about a project, which requires costly experimentation by both parties to succeed. In equilibrium, investors learn about the project from the arrival of exogenous...
