We analyze the allocation of talent across teams in large matching markets with competition for rank. We show that under general conditions globalization in the form of a convex transformation of payoffs promotes the concentration of talent, i.e. it makes positive assortative matching more...

For a period starting in 2015, Apple, Google, and Microsoft became the most valuable companies in the world. Each was marked by an external developer ecosystem.

We study the effects of an intervention aimed at identifying and containing outbreaks in a network model of contagion where social distance is endogenous. The intervention induces a fall in the risk of infection, to which agents optimally respond by reducing social distance. If the intervention...
