We study the relationship between patents and actual product innovation in the market, and how this relationship varies with firms' market share. We use textual analysis to create a new data set that links patents to products of firms in the consumer goods sector. We find that patent filings are...

The last decades have seen large improvements in digital advertising technology that allowed firms to better target specific consumer tastes. This research studies the relationship among digital advertising, the rise of varieties, and economic welfare. We develop a model of advertising and...

We use the Mexican labor market structure to price the set of fringe benefits that household heads receive when formally employed. We exploit longitudinal, nationally-representative information on household heads who are formal, informal, or switch status at least once in our data. Using monthly...

Our paper addresses the heterogeneous effects of monetary policy on households of different races. The cyclical volatility of real income differs significantly for households of different races and income levels, reflecting differential exposure to fluctuations in employment and consumer prices....

Structural transformation and regional convergence in U.S. income have been long-standing trends. Caselli and Coleman (2001) discovered that 60% of regional convergence between the U.S. South and North from 1940 to 1990 is due to structural transformation. Our replication confirms these robust...

The disparities in cross-country labor productivity are greater in agriculture than in other industries. I propose that the misallocation of female talent across sectors distorts productivity. I formalize the theory by using a general equilibrium Roy model with gender-specific frictions. If...

We design, pilot, and field a new survey of occupational skills in Peru, to investigate human capital differences between poor and rich countries. Though the average skill level is comparable, Peruvian jobs have markedly more uniform skill profiles than jobs in the US. However, matching...

We analyze the evolution of the plant size distribution, static allocative efficiency, and business dynamism of the Korean manufacturing sector during its growth miracle (1967–2000) and the subsequent slowdown since 2000. The average plant size has an inverse-U pattern over time, uncorrelated...

We design, pilot, and field a new survey of occupational skills in Peru, to investigate human capital differences between poor and rich countries. Though the average skill level is comparable, Peruvian jobs have markedly more uniform skill profiles than jobs in the US. However, matching...

Some economies are "black holes" where reliable data is scarce due to government control, low capacity, or conflict. Despite these challenges, researchers have found ways to gather useful information. This paper draws on the literature on North Korea to review six key methods: satellite imagery,...
