Innovative activity is highly concentrated in a handful of advanced countries. These same countries are also the major exporters of capital goods to the rest of the world. We develop a model of trsde in capital goods to assess its role spreading the benefits of technological advances.

We develop a Ricardian model to explore the role of trade in spreading the benefits of innovation.

Countries differ in their absolute and relative productivities in doing research across different technologies. They also differ in their propensity to adopt different technologies from abroad. Moreover, technologies may vary in their international mobility. We make use of new data on...

We develop a framework for estimating the optimal expenditure of agents subject to unobserved liquidity constraints. OUr framework allows us to estimate credit ceilings as well as preference parameters. We apply the framework to data on net resource transfers from private lenders to twenty-nine...

Our recent work examines the links among innovations, technology, trade, and growth. One strand focuses on research activity, technology diffusion, and growth. The other examines technology and trade. In this paper we exploit the common treatment of technology in these two strands to provide a...
