This paper analyzes the relationship between human capital and convergence with a model that takes into account the different effects of human capital accumulation on regional convergence. As an input, human capital produces convergence due to both decreasing returns and public intervention on...

This paper analyses the regional wages in Spain and tests their relationship with the different regional human capital endowments, using an approach that takes into account the possible measurement error in human capital indicators. The results indicate that, when allowing for the possibility of...

In this paper we analyze firms' ability to tacitly collude on pricesin an infinitely repeated duopoly game of vertical productdifferentiation. We show that firms collude if and only if their discountfactor is high enough, i.e. if they value future profits sufficiently. We alsoshow that a lower...

Competition has long been regarded as productivity enhancing. Understanding the mechanism by which competition affects innovation and productivity is therefore an important topic for economic policy. The main contribution of this paper is to disentangle the relationship between competition and...

This paper analyzes the Spanish case, in which a significant degree of regional inequality exists along with scarce net migratory flows. Therefore, we consider spatial differences on human capital returns as a determinant of migration instead of per capita income or wage per worker, as empirical...

In this paper, we show that downstream mergers increase the incentives of an up-stream firm to invest in cost-reducing R&D. The upstream firm revenues increase with industry profits, which in turn increase with concentration downstream and this explains the positive link between concentration...

In the context of the recent electricity market reforms in Europe and the US, we evaluate the performance of the Spanish pool. Our method is not based on price-cost estimates but rather on the different behavior of operators with higher market power as compared to the behavior of more...

The microeconomic model we consider includes the most important aspects of educational choices. The results show how social background, family earnings and...
