We study the impact of university-industry research collaborations on academic output, in terms of productivity and direction of research. We report findings from a longitudinal dataset on all the researchers from the engineering departments in the UK in the last 20 years. We control for the...

In recent years, Spain has received unprecedented immigration flows. Between 2001 and 2006 the fraction of the population born abroad more than doubled, increasing from 4.8% to 10.8%. For Spanish provinces with above-median inflows (relative to population), immigration increased by 24% the...

We estimate the aggregate long-run elasticity of substitution between more and less educated workers (the slope of the demand curve for more relative to less educated workers) at the US state level. Our data come from the (five)1950-1990 decennial censuses. Our empirical approach allows for...

This paper evaluates the empirical and theoretical contributions of the Economic Growth Literature since the publication of Paul Romer’s seminal paper in 1986.

A prolonged confrontation between Yahoo! Inc. and French anti-racism activists who ask for the removal of Nazi items from auction sites as well as restricted access to neo-Nazis sites is analyzed. We present the case and its development up to the decision of Yahoo! Inc. to remove the items from...

Regulations that constrain firms' externalities in one dimension can distort incentives and worsen externalities in other dimensions. In Peru's industrial fishing sector, the world's largest, fishing boats catch anchovy that plants along the coast convert into fishmeal. Matching administrative,...

Some natural resources—oil and minerals in particular—exert a negative and nonlinear impact on growth via their deleterious impact on institutional quality. We show this result to be very robust. The Nigerian experience provides telling confirmation of this aspect of natural resources. Waste...

Applying the competing--risks model to multi--cause mortality, this paper provides a theoretical and empirical investigation of the positive complementarities that occur between disease--specific policy interventions. We argue that since an individual cannot die twice, competing risks imply that...

In this paper we compare several historical scenarios very different one to each other both in institutional and geographical terms. What they have in common is the situation of relative poverty of most of the population. On the one part we are dealing with historical industrializing Catalonia...

The dismal growth performance of Africa is the worst economic tragedy of the XXth century. We document the evolution of per capita GDP for the continent as a whole and for subset of countries south of the Sahara desert. We document the worsening of various income inequality indexes and we...
