We develop a tractable growth model to study the dynamic macroeconomic effects of multinational production (MP) across countries. In this model, MP is the vehicle of international idea diffusion: when firms produce in a foreign country, they contribute to the local stock of knowledge. We...

Cross-country data reveal that the per capita incomes of the richest countries exceed those of the poorest countries by a factor of thirty-five. We formalize a model with embodied technical change in which newer, more productive vintages of capital coexist with older, less productive vintages. A...

Because the returns to successful industrial research generally enjoy a larger scale economy than that to successful scientific research, this paper shows that while economic integration increases R&D employment, it may not raise the rate of long-run economic growth due to the shift of resources...

This paper integrates in a unified and tractable framework some of the key insights of the field of international trade and economic growth. It examines a sequence of theoretical models that share a common description of technology and preferences but differ on their assumptions about trade...

I develop a model for a small, open, technology-lagging economy that imports leading-edge knowledge from the technology leader by paying high-skilled researchers from the leading country their opportunity cost to train the lagging country's future high-skilled workers while adding to a local...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...

We add to recent evidence on deindustrialization and document a new pattern: increasing industry polarization over time. We assess whether these new features of structural change can be explained by a dynamic open economy model with two primary driving forces, sector-biased productivity growth...
