We study the international transmission of the monetary policy of the two world’s giants: China and the US. From East to West, the channels of global transmission differ markedly. US monetary policy shocks affect the global economy primarily through their effects on integrated financial markets,...

We study the quantitative stability of the mapping that to a measure associates its pushforward measure by a fixed (non-smooth) optimal transport map. We exhibit a tight Hölder-behavior for this operation under minimal assumptions. Our proof essentially relies on a new bound that quantifies the...

Empirical research typically involves a robustness-efficiency tradeoff. A researcher seeking to estimate a scalar parameter can invoke strong assumptions to motivate a restricted estimator that is precise but may be heavily biased, or they can relax some of these assumptions to motivate a more...

Do search engines produce better results because their algorithm is better, or because they can access more data from past searches? We document that the algorithm of a small search engine can produce non-personalized results that are of similar quality to the dominant firm’s (Google) if it has...

How has mobile internet affected political polarization in the United States? Using Gallup Daily Poll data covering 1,765,114 individuals in 31,499 ZIP codes between 2008 and 2017, I perform a difference-in-differences analysis and an instrumental-variable design to show that, after gaining access...

In this paper we analyze a continuous-time Coase setting with finite horizon, interdependent values, and different discount rates for the buyer and seller. We fully characterize the equilibrium behavior, which permits us to study how the agents’ discount rates (i.e., patience levels) shape the...

Across species and cultures, individuals partition themselves by forming non-overlapping groups. Animals divide into herds, children separate into groups during playtime, politicians create competing political parties, and countries join multilateral defensive treaties. Social network analysis...
