Estimating Human Capital Externalities:The Case of Spanish Regions

We estimate the strength of schooling externalities for Spanish regions over the 1981-2001 period. Our empirical work employs both main approaches available in the literature. Both methodologies yield significant externalities. Using a growth accounting exercise, we find that human capital externalities account for one half of the increase in real wages for the period between 1981 and 2001.externalities, human capital, constant composition.
