This paper examines the impact of cultural diversity on innovation. Focusing on the United States from 1850 to 1940, we develop a novel surname-based measure of cultural diversity and combine this with patent data. Leveraging quasi-random variation in counties' surname compositions driven by...

Many platforms charge percentage commissions on third-party sales. They may also charge per unit fees on ancillary services (such as FbA for Amazon's shipping and warehousing), and they may authorize (or be obliged) to offer seller opt-out of such services. We analyze the economics of these options...

Female labor force participation remains lower than male participation in many settings. Can this be explained by households’ preference for men’s work, and are these preferences malleable? We address this question with a field experiment in a refugee camp setting in Bangladesh, where we randomly...

How to go beyond the square distance d² in optimization algorithms and flows in metric spaces? Replacing it with a general cost function c(x,y) and using a majorize-minimize framework I will detail a generic class of algorithms encompassing Newton/mirror/natural/Riemannian gradient descent/Sinkhorn...
