We develop a model of endogenous skill-biased technical change in developing countries.  The model reconciles wildly dispersed existing estimates of the elasticity of substitution between more and less educated workers.  It also produces an estimating equation for the elasticity, which allow...

The paper attempts to synthesize the research to date on the contribution of international trade to rising income inequality in the US and to other labour-market developments in other countries. Our basic conclusion is that despite using very different methodologies, on balance most labour and...

This paper surveys the experience of economic growth in the 20th century with a focus on technological change at the frontier together with issues related to success and failure in catch-up growth.  A detailed account of growth performance based on historical national accounts data is given and...

The commercial value of basic knowledge depends on the arrival of follow-up developments mostly from outside the boundaries of the inventing firm. Private returns would depend on the extent the inventing firm internalizes these follow-up developments. Such internalization is less likely to occur...

This paper uses the adoption and invention of the spinning jenny as a test case to understand why the industrial revolution occurred in Britain in the eighteenth century rather than in France or India.  It is shown that wages were much higher relative to capital prices in Britain than in other...

What is the impact of joining the European Union on a small, less developed economy? This is the general question driving this research paper. In particular, the role of factor movements in explaining real wage behavior in Portugal after its entry in the European Union (EU) is evaluated. Based...

It is shown that spillovers can enhance private returns to innovation if they feed back into the dynamic research of the original inventor (Internalized spillovers), but will always reduce private returns, if the original inventor does not benefit from the advancements other inventors build into...

Demand for less skilled workers decreased dramatically in the US and in other developed countries over the past two decades. We argue that pervasive skill biased technological change rather than increased trade with the developing world is the principal culprit. The pervasiveness of this...

Much of the dramatic change in skill and wage structure observed in recent years in the United States is believed to stem from the impact of new technology. This paper compares the changing skill strcuture of wage bills and employment in the United States with six other advanced developed...
