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.

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...

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...

The relative distribution of the populations of the top 40 urban areas of France and Japan remained very constant during these countries' periods of industrialization and uranization. Moreover, projection of their future distriubtions based on past growth indicates that their size-distributions...

We develop a simple model of the choice between exploiting a technology in another country via export and via direct foreign investment. The model points to the destination country's size, level of technological sophistication, and distance from the source as factors in the decision. Moreover,...

We develop and estimate a model of technological innovation and its contribution to growth at home and abroad. International patents indicate where innovations come from and where they are used. Countries grow at a common steady-state rate A country's relative productivity depends upon its...

The troublesome debts of a number of developing Countries have spawned a large literature on why countries borrow, on what debt contributes to growth, on why countries repay, and on how existing debt should be dealt with. This paper provides a basic introduction to some issues in sovereign debt....

We model the invention of new technologies and their diffusion across countries. Our model predicts that, eventually, all countries will grow at the same rate, with each country's productivity ranking determined by how rapidly it adopts inventions. The common growth rate depends on research...
