This paper investigates earnings differentials between immigrants and natives. We focus on returns and on the (imperfect) international transferability of human capital. Data are drawn from the 2009 Italian Labour Force Survey (LFS). We show that returns to human capital are considerably lower...

We evaluate the effects of employer-provided formal training on employee suggestions for productivity improvements and on promotions among male blue-collar workers. More than twenty years of personnel data of four entry cohorts in a German company allow us to address issues such as unobserved...

I ask generally whether a country can benefit from the temporary importation of human capital, and specifically whether a program that attracts large groups of academic visitors to a distant country benefits it by generating additional scholarly research on local issues. Using the list of...

In this paper we investigate how fertility decisions respond to unexpected career interruptions which occur as a consequence of job displacement. Using an event study approach we compare the birth rates of displaced women with those of women unaffected by job loss after establishing 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...

An individual?s human capital has a strong influence on earnings. Yet individual, worker-level estimations of earnings rarely include the characteristics of co-workers or detailed firm-level controls. In this paper, we use a unique matched worker?workplace dataset to estimate the effect on own...
