This paper presents a theory where increases in female labor force participation and reductions in the gender wage-gap are generated as part of a single process of demographic transition, characterized by reductions in mortality and fertility. The paper suggests a link between changes in...

Growth of technological variety offers more scope for the division of labor. And when a division of labor requires some specific training, the technological specificity of human capital grows and, with it, probably the firm specificity of that capital. We build a simple model that captures this...

We study how the inventive capability of a firm conditions its participation in a division of innovative labor. Capable firms are, by definition, able to invent; for them, external inventions substitute for their own R&D. However, external knowledge is an input into internal invention, and thus,...

We investigate the role of industry specialization in horizontal cross-border mergers and acquisitions. We find that acquirers from more specialized industries in a country are more likely to buy foreign targets in countries that are less specialized in these same industries. The role of...

A growing literature suggests that high-income countries export high-quality goods. Two hypotheses may explain such specialization, with different implications for welfare, inequality, and trade policy. Fajgelbaum, Grossman, and Helpman (2011) formalize the Linder hypothesis that home demand...

Policies aiming to improve healthcare productivity often focus on reducing care fragmentation. Care fragmentation occurs when services are spread across many providers, potentially making coordination difficult. Using Medicare claims data, we analyze the effect of moving to a region with more...

In the Wealth of Nations, Adam Smith argues that a country's national income depends on its labor productivity, which in turn hinges on the division of labor. But why are some countries able to take advantage of the division of labor and become rich, while others fail to do so and remain poor?...

Even though teams have become the dominant mode of knowledge production, little is known regarding how they divide work among their members. Conceptualizing knowledge production as a process involving a number of functional activities, we first develop a conceptual framework to study the...

Industrial revolution in the United States first took hold in rural New England as factories arose and grew in a handful of industries such as textiles and shoes. However, as factory scale economies rose and factory production techniques were adopted by an ever growing number of industries,...

Theory indicates that internally-differentiated professional partnerships can promote matching between heterogeneous consumers and professionals, particularly when consumers have imperfect information or markets have barriers to referrals between firms. We test this in obstetrics markets,...
