In models in which convergence in income levels across closed countries is driven by faster accumulation of a productive factor in the poorer countries, opening these countries to trade can stop convergence and even cause divergence. We make this point using a dynamic Heckscher-Ohlin model - a...

This paper analyses the e¤ect of a resource discovery on an open economy with endogenous directed technical change. Technical progress depends on entrepreneurs who produce (or adopt) technology, and endogenously choose which sector to operate in. The static e¤ect of a resource discovery is de-...

This paper demonstrates, in the context of a two-sector OLG neoclassicalgrowth model, conditions under which international trade in consumptiongoods alone may be sufficient for the equalization of real returns to physicalcapital across countries; that is, under which commodity arbitrage is...

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...

The closed economy neoclassical model predicts lung-run convergence in per-capita income. We show, within a neoclassical framework, that international trade among two countries differing only in their initial capital endowment generates long-run income differences. Our results suggests that...

This paper studies the origins and consequences of international technology gaps. I develop an endogenous growth model where R&D efficiency varies across countries and productivity differences emerge from firm-level technology investments. The theory characterizes how innovation and learning...

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...

Over the last decades, large labor intensive countries, like China, have played a growing role in world trade. Using the factor proportions theory, this paper investigates the dynamic effects of economic growth consequent to international trade between countries with different factor...
