Technology spillover effects within Spanish communities

The article uses panel data for the period 1990–2010 to estimate technology spillover effects on 17 Spanish communities. Accounting for nonstationarity and cointegration, we use the dynamic OLS estimator to estimate the impact of domestic and non-domestic R&D capital stock on labour productivity of Spanish communities, taking into account trade-, migration- and foreign direct investment (FDI)-related technology diffusion channels. We find significant trade-related spillover effects within Spanish communities and from EU countries. On average, an increase in the non-domestic R&D stock of 1% increases their labour productivity between 0.02% and 0.12% if related to bilateral trade pattern. Moreover, migration within Spanish communities has a negative impact ranging between −0.07% and −0.16% on labour productivity as the impact of inward migration is dominated by outward migration. There is no robust impact from FDI inflows of OECD countries in general or EU countries in particular. Finally, the domestic R&D stock, physical capital and human capital are shown to be significant drivers for labour productivity in Spain no matter if non-domestic (local or foreign) spillover effects are trade-, migration- or FDI-related.
