A model is developed in which two complementary forms of investment contribute to growth--technology and skill acquisition, and growth takes two forms--TFP and variety growth. The rate of TFP growth depends more heavily on the parameters governing skill accumulation, while variety growth...

Census data from international sources covering 77% of the world's migrant population indicate that the skill composition of migrants in major destination countries, including the US, has been rising over the last 4 decades. Moreover, the population share of skilled migrants has been approaching...

This essay discusses the effect of technical change on wage inequality. I argue that the behavior of wages and returns to schooling indicates that technical change has been skill-biased during the past sixty years. Furthermore, the recent increase in inequality is most likely due to an...

This paper develops a model of skill formation that explains a variety of findings established in the child development and child intervention literatures. At its core is a technology that is stage-specific and that features self productivity, dynamic complementarity and skill multipliers....

Although many developing countries have experienced growing income inequality and an increase in the relative demand for skilled workers during the 1980s, the sources of this trend remain a puzzle. This paper examines whether investment and adoption of skill-biased technology have contributed to...

Adapting our earlier model of multinationals, we address policy issues involving wages and labor skills. Multinational firms may arise endogenously, exporting their firm-specific knowledge capital to foreign production facilities, and geographically fragmenting production into skilled and...

We develop a new estimator for the process of children's skill formation in which children's skills endogenously develop according to a dynamic latent factor structure. Rather than assuming skills are measured perfectly by a particular measure, we accommodate the variety of skills measures used...
