We propose a mechanism for labor-market polarization based on the nonhomotheticity of demand that we call the income-driven channel. Our mechanism builds on a novel empirical fact: expenditure elasticities and production intensities in low- and high-skill occupations are positively correlated...

Did trade integration suppress inflation in the United States? We say no, in contradiction to the conventional wisdom. Our answer leverages two basic facts about the rise of trade: offshoring accounts for a large share of it, and it was a long-lasting, phased-in shock. Incorporating these...

Standard methods for estimating total factor productivity (TFP) growth assume that economic profits are zero and adjustment costs are negligible. Moreover, following the seminal contribution of Basu, Fernald and Kimball (2006), they use changes in hours per worker as a proxy for unobserved...

We collected data on the sophistication of technologies used at the business function level for a representative sample of firms in Vietnam, Senegal, and the Brazilian state of Ceará. Our analysis finds a large variance in technology sophistication across the business functions of a firm....

We document the structural transformation of innovation using historical patent data since the 1850s, along with R&D expenditure and TFP growth for the post-war period. Over time, innovation has shifted from agricultural sectors to manufacturing, and, more recently, to services. We develop and...

Variation in technology adoption is a key driver of differences in productivity. Previous studies sought to explain variations in technology adoption by heterogeneity in profitability, costs of adoption, or other factors. Less is known about how adoption is affected by bias in the perceived...

This paper estimates the impact of technology sophistication pre-COVID-19 on the performance of firms during the early stages of the pandemic. We exploit a unique data covering firms from Brazil, Senegal, and Vietnam using a treatment effect mediation framework to decompose the results into a...

We compute new estimates for Total Factor Productivity (TFP) growth in five European countries and in the United States. Departing from standard methods, we account for positive profits and use firm surveys to proxy for unobserved changes in factor utilization. These novelties have a major...

We estimate the causal effect of the diffusion of solar photovoltaic (PV) systems on the fraction of Green Party votes in federal and state elections in Baden-Württemberg, Germany. Our estimates are based on instruments that induce exogenous variation in roof appropriateness to PV installation....

During the recovery from the COVID-19 pandemic, international shipping and logistics capacity was strained, limiting the quantity of imports. We investigate the impact of an import constraint on inflation, following an increase in domestic demand. Whether the binding import constraint raises...
