Empirical growth regressions typically include mean years of schooling as a proxy for human capital. However, empirical research often finds that the sign and significance of schooling depends on the sample of observations or the specification of the model. We use a nonparametric local-linear...

This study compares the determinants of productivity and wages at both firm and worker level. In the firm-level analysis, we follow Hellerstein, Neumark and Troske (1999) and provide improved estimates based on an extended set of covariates including the intensity of firm-provided training. In...

We evaluate the effect of technology, demographics and policy on the differential evolution of the skill premium and on the rise in education investment in France and the USA. We use a computable general equilibrium model with overlapping generations of individuals, and endogenous education...

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...

This paper examines the welfare implications associated with different degrees of diversity or similarity between migrants and natives under both migration and trade. We use a general equilibrium model of migration, human capital and social capital and find that there are three equilibrium...

This paper explores the theoretical issues and the empirical literature regarding the selectivity of migrants. Although the primary focus is on international migration, reference is made to internal migration and return migration. The theoretical analysis indicates a tendency toward the...

We develop a rationale for the payment by firms of a wage premium on marginal, or overtime, weekly hours. We examine wage-hours contracts within the framework of a two-period specific human capital model with asymmetric information. The wage premium serves to achieve contract efficiency. For...

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...

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...
