Significant progress reconciling economic activities with a stable climate requires radical and rapid technological change in multiple sectors. Here, we study the case of the automotive industry's transition to electric vehicles, which involved choosing between two different technologies: Fuel Cell...

It was established in the 90's by Pemantle, Brandière and Duflo that stochastic gradient descent (SGD) escapes saddle points of smooth function. Knowing that critical points of a typical/generic smooth function are either local minima or saddle points, we can interpret this result as a generic...

In response to women’s changing roles in labor markets, couples have adopted varied strategies to reconcile career and family needs. Yet, most studies on the gendered division of labor focus almost exclusively on changes either in work or family domain. Doing so neglects the process through which...

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...

Zackary Dunivin is a candidate in Complex Systems and Sociology at Indiana University. His work draws on various computational tools to study culture and cultural change from the perspectives of dyadic interactions, group dynamics, social movements and formal organizations. This talk presents...

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...
