This paper presents a comparative analysis of productivity growth in the U.S. and Japanese electrical machinery industries in the postwar period. This industry has experienced rapid growth in output and productivity and high rates of capital formation in both countries. A substantial amount of...

We collect time-use data for entrepreneurs and their workers in over 1,000 manufacturing firms in urban Uganda. We document limited labor specialization within the firm for establishments of all sizes and argue that this is likely due to the prevalence of product customization. We then develop a...

We develop a tractable framework for the analysis of the relationship between contractual incompleteness, technological complementarities, and technology adoption. In our model a firm chooses its technology and investment levels in contractible activities by suppliers of intermediate inputs....

What is the role of firms and markets in mediating the division of labor? This paper uses confidential microdata from the Census of Services to examine law firms' boundaries. We find that firms' field scope narrows as market size increases and individuals specialize, indicating that firms'...

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...

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...

We develop an empirical approach for identifying specialization in bank lending using granular data on borrower activities. We illustrate the approach by characterizing bank specialization by export market, combining bank, loan, and export data for all firms in Peru. We find that all banks...

A widely held view is that openness to international trade leads to higher GDP volatility, as trade increases specialization and hence exposure to sector-specific shocks. We revisit the common wisdom and argue that when country-wide shocks are important, openness to international trade can lower...

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?...

We conduct the first empirical test of the knowledge burden hypothesis, one of several theories advanced to explain increasing team sizes in science. For identification, we exploit the collapse of the USSR as an exogenous shock to the knowledge frontier causing a sudden release of previously...
