This paper investigates two channels through which research and development (R&D) and human capital may affect regional total factor productivity growth in the manufacturing sector, using panel data on 159 EU-15 regions from 1992 to 2005.  Based on the endogenous growth model of Griffith,...

The labour productivity differentials between manufacturing firms in Ghana and South Korea exceed those implied by macro analysis.  Median value-added per employee is nearly 40 times higher in South Korea than Ghana.  The most important single factor in explaining this difference is the...

A large majority of the labour force were manual workers in 1960.  As voters, they had electoral power to pursue collective goods.  As producers they were able to disrupt production.  The majority left school with no qualifications.  Their human capital consisted of skills specific to...

Important gaps remain in the understanding of the economic consequences of civil war.  Focusing on the conflict in Rwanda in the early 90s, and using micro data to carry out econometric analysis, this paper finds that households and localities that experience more intense conflict are lagging...

The article aims to present and discuss estimates of levels of human and social capital in Italy's regions over the long term, i.e. roughly from the second half of the nineteenth century up to the present day.  The results are linked to newly available evidence for regional value added in order...

Vocational training systems differ markedly between countries. A model of firm-based human capital investment predicts equilibria characterised by particular patterns of training and job-to-job mobility, consistent with observed cross-country differences. Incentives to invest in human capital...

The growth process for a technological leader is different from that of a follower. While followers can grow through imitation and capital deepening, a leader must undertake original research. This suggests that as the gap between the leader and the follower narrows, the follower must undertake...

A positive correlation between relative position and the neurotransmitter serotonin exists in non-human primates, within an optimal range. This paper explores the reasons of this correlation. The main function of serotonin appears cognitive: it determines how optimally agents perceive and behave...

Why might there be a long-run trade-off between growth and unemployment? In general equilibrium, the returns on the factors of production are interdependent. This paper develops a model where the determination of the wage is central to the evolution of these incentives. The incentive to hire...
