Immigration has recently been at the centre of the political and economic agenda. Economists have studied extensively the impact of immigration on several economic and social indicators of host countries. The effect of immigration on innovation and technical change is, however, not much studied....

We use small Italian regions (i.e. provinces) to investigate the causal effect of foreign immigration on innovation during 2003-2008. Using instrumental variables estimation (based on immigrants' enclaves), we find that the overall stock of immigrants did not have any effect on innovation....

This paper focusseses on the strategic use of firms' R&D agreements to overcome R&D inefficiencies in presence of asymmetric information and research spillovers. We introduce a duopoly game where initially one firm is not fully informed on its rival's R&D productivity. We show that, without R&D...

This paper investigates the fragmentation of the EU innovation system in the field of renewable energy sources (RES) by estimating the intensity and direction of knowledge spillovers over the years 1985-2010. We modify the original double exponential knowledge diffusion model proposed by...
