Welcome to ResearchDMR,
the Academic website for David M. Rothschild

On this site, I provide information about my background, research, and a few random thoughts. I am a Senior Principal Research Manager—and an economist—at Microsoft Research in New York City. I earned my Ph.D. in applied economics from the Wharton School of the University of Pennsylvania, where my advisor was Justin Wolfers. I have written extensively in both the academic and popular press. My work pushes the boundaries of diverse data and methods, including large language models, polling, prediction markets, social media and online data, and large-scale behavioral and administrative data. It focuses on practical and compelling questions, including the impact of AI on people, organizations, the economy, and society; the measurement and evolution of public opinion; the market for news; the effects of advertising; finance; and an economist’s perspective on public policy.

I am also a Co-PI for PennMap at University of Pennsylvania. Check out the The Media Bias Decector to learn about what the media chooses to cover on any given day.
