We study the impact of firm level choices of ICT, R&D, exporting and importing on the evolution of productivity and its bias towards skilled occupations. We use a novel measure of the propensity of a firm to engage in technology investment and adoption: its employment of workers with STEM...

Income disparity across countries has been large and widening over time. We develop a tractable model where factor requirements in production technology do not necessarily match a country's factor input profile. Appropriate assimilation of frontier technologies balances such multi-dimensional...

After more than three decades of high growth that was based on an exploration of its low-wage advantage and a relatively favorable demographic pattern in combination with market-oriented reforms and openness to the world economy, China is at a crossroad with a much higher wage and a shrinking...

We estimate direct and indirect effects of total factor productivity growth in manufacturing on US workers' earnings, housing costs, and purchasing power. Drawing on four alternative instrumental variables, we consistently find that when a city experiences productivity gains in manufacturing,...

This paper examines trends in the aggregate productivity of the pharmaceutical sector over the past three decades. We incorporate Ricardo's insight about demand-driven productivity in settings of variable scarce resources, and estimate the industry's responsiveness to changes in demand over this...

We construct an endogenous growth model with random interactions where firms are subject to distortions. The TFP distribution evolves endogenously as firms seek to upgrade their technology over time either by innovating or by imitating other firms. We use the model to quantify the effects of...

We estimate the trend in the transitory variance of male earnings in the U.S. using the Michigan Panel Study of Income Dynamics from 1970 to 2004. Using both an error components model as well as simpler but only approximate methods, we find that the transitory variance started to increase in the...
