This paper develops a production function which two separate elasticities of substitution between two input factors. One of these elasticities is obtained if the factor intensity equals a particular baseline value. The second part of the paper gives an economic application and shows the...

In skill-biased (deskilling) technological revolutions, learning investments required by new machines are greater (smaller) than those required by preexisting machines. Skill-biased (deskilling) revolutions trigger reallocations of capital from slow- (fast-) to fast- (slow-) learning workers,...

Although microeconomic studies find a positive relationship between R&D and skill premia, much of the recent rise in U.S. wage inequality was accompanied by slowing labor-productivity growth and relatively slow introduction of new technologies. These conflicting observations are consistent with...

In this paper we investigate how telecommunications infrastructure affects economic growth. We use evidence from 21 OECD countries over a 20-year period to examine the impacts that telecommunications developments may have had. We jointly estimate a micromodel for telecommunication investment...

We explore how participation in social networking sites (SNS) such as Facebook and Twitter affects the most economically relevant aspect of social capital, trust. We use measures of trust in strangers (or social trust), trust in neighbours and trust in the police. We address endogeneity in the...

During the last decades, wage inequality in Germany has considerably increased both within and across regions. Building on concepts of the task-based approach, this paper studies whether and to what extent these developments are driven by technological change. We present novel evidence that...

This paper analyzes the polarization of employment and wages in Germany between 1979 and 2006, focusing on the role of technological progress. We exploit spatial variation in the exposure to technological progress which arises due to initial regional specialization in routine task-intensive...

During the last years the worldwide legal framework has stimulated the biofuel development, causing their production and use to be exhaustively studied. Biodiesel has been mostly produced in European countries, but the agronomic potential of the Latin-American countries has led the effort toward...
