Il contenuto di capitale umano dei flussi migratori interregionali:1980-2002
No full textIn this paper we analyse the human capital endowment of migration flows across Italian regions during the period from 1980 to 2002. Our aim it to quantify the human capital embodied into migrants in order to assess how much of it has been moving from one region to another. Among the main results we have found that interregional mobility slowed down up to 1995 but has been increasing from then onwards, in addition we have also discovered that during the whole time period emigration rates are higher for graduate students, followed by higher secondary school and lower secondary school students. The main finding, however, is that we have detected evidence of human capital losses for almost all southern regions. Putting it differently these regions have suffered from a brain drain that, presumably, has reduced their growth potentials
Growth, Congestion of Public Goods, and Second-Best Optimal Policy: a Dynamic Analysis
No full textThis paper presents a general equilibrium endogenous growth model in which public spending is divided between public productive services and public consumption. A distinguishing feature of the model is the assumption that both components of public spending can be overused and, thus, congested by the private agents. We study the second-best dynamics of the model and prove that it is determinate. In addition, we show that, although there could be different outcomes for the second-best problem, the optimal second-best policy is unique. Finally, the relationship between congestion and the optimal second-best policy, on the one hand, and congestion and the equilibrium growth rate, on the other, is established
Rendimento del capitale umano, qualità dell’istruzione e fuga dei cervelli dal Mezzogiorno
No full textIn this paper we analyse the so-called “new migrations” across Italian regions, taking explicitly into account both graduates and the whole population. As regards graduates, we emphasize that net migration in southern regions has always been negative and that it has gone further deteriorating in recent years. As far as population is concerned, we estimate the human capital endowment that considers both region-specific rates of returns and a region-specific index of educational quality. Following such an approach, once more, we are able to highlight that southern regions have suffered from a net loss of human capital of which central-northern regions have taken advantage. Finally, we estimate the influence of interregional migration flows on regional added value in order to quantify their impact in terms of output losses
From Solow’s growth theory to endogenous growth theories: convergence and divergence in economic growth
No full textCan the augmented Solow model with migration explain the Italian internal brain drain?
No full textWe extend the Dolado et Al. (1994) model to both inflows and outflows of migrants and assume that they have a human capital endowment that contributes to increase/decrease the stock of human capital in the receiving/sending economy. We derive the conditional convergence equation in which the impact of migration flows on the growth rate is disentangled in a pure quantity effect and in a quality or composition effect of immigration and emigration rates that accounts for the relative human capital endowment of migrants with respect to resident population. Next, we test the model with Italian regional data for the 1970-2005 time period. We find that the model provides a good explanation of the Italian experience. The quantity effect is negative for the immigration rate and positive for the emigration rate, while the composition effect is positive for immigration and negative for emigration. Finally, we separate the centre-north from the south and find that the composition effect of emigration is stronger for the latter. We interpret these results as a clear evidence of a brain drain from the Mezzogiorno to the centre-northern regions
