This paper uses micro data from the Demographic National Survey and the Census in Romania (2002-2003) and in Countries that have received large number of Romanian immigrants over the period 1990-2000 (US, Austria and Spain) to identify the wage earning ability (skills) of migrants and returnees...

This paper studies the innovation strategies of multi-product firms in industries with different scope for product differentiation. In a simple model of multi-product firms, we show that returns to product versus process innovation are industry-specific. Demand and cost linkages induce a natural...

In this paper, I investigate welfare gains associated with trade induced intra-firm adjustments of multi-product firms. To disentangle the welfare gains, I split up the R&D portfolio of a multi-product firm into three different channels: i) product innovation, ii) investments in the degree of...

In this paper, we incorporate offshoring of labor-intensive goods in a model with multi-product firms, and explore its implications in partial and general oligopolistic equilibrium. We identify important aspects of this phenomenon and argue that improvements in offshoring opportunities can...

We show that the labor market effects of product line relocations within multi-product firms differ significantly from the relocation of production tasks within single-product firms. By incorporating offshoring of labor-intensive goods in a model with multi-product firms, and exploring its...

We analyze how foreign direct investment (FDI) affects employment security using administrative microdata for German employees. Measuring FDI intensity at the industry level enables us to take into account the sum of direct effects at multinationals as well as indirect effects of FDI throughout...

Using harmonized micro data, this paper investigates the job search behaviour of the unemployed in Europe. The analysis focuses on the importance of individual and household characteristics in this context, as well as on cross-country differences in Europe. Our findings suggest that both...

Magnetic nanoparticles can be employed for a broad range of biomedical applications where the knowledge of the distribution of the magnetic nanoparticles is of importance for efficacy, patient’s safety, etc. The need exists to have an as accurate as possible quantification of the unknown...
