In this paper, we analyze the extent to which market forces create an incentive for cloning human beings. We show that a market for cloning arises if a large enough fraction of the clone?s income can be appropriated by its model. Only people with the highest ability are cloned, while people at...

Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national...

Thurow?s job-competition model implies that overeducation is contingent upon the differing skill endowments of employees. As yet, only rudimentary evidence has been furnished to confirm this relationship. In the present paper, we test the theory in a more sophisticated manner, by means of a more...

This paper studies how portable skill accumulated in the labor market are. Using rich data on tasks performed in occupations, we propose the concept of task-specific human capital to measure the transferability of skills empirically. Our results on occupational mobility and wages show that labor...

In this paper I discuss a structural problem facing the United States with respect to our policy responses in the context of trade and technological change and their impact on workers. Both trade and technological change have put enormous pressure on the U.S. economy to raise the skill level of...

This paper analyses the economic issues associated with human cloning and new reproductive technologies. We analyze the incentives for human cloning and its implications for the long run distribution of skills and income. We analyse models of human cloning for different motives, focusing on...

I study a model where Information Technology, while typically increasing overall inequality, is likely to harm some people at intermediate and high levels of the distribution of income but to benefit people at the bottom. Within a given occupation it may harm some workers while benefitting...

This paper reviews Jacob Mincer?s contributions to the analyses of earnings and the distribution of earnings through his pioneering focus on labor market experience or on-the-job training. It begins with a brief discussion of the theoretical literature on the distribution of earnings in the...
