Persistence in inequalities across the Spanish regions

In this paper we investigate several issues concerning persistence in inequalities of relative income per capita among the Spanish regions over 1980-2002. For that purpose we take a Bayesian approach which extends the work by Canova and Marcet (1995). Firstly, we study to what extent there exists a fixed effect bias in the standard cross-section estimates, and we find that the speed of convergence is indeed underestimated. Secondly, we provide a battery of results in which steady states and convergence rates have been obtained for a continuum of prior distributions. Finally, we also deal with persistence in inequalites by determining whether initial conditions matter in the distribution of regional steady states, and our conclusion is that regional disparities tend to persist over time in Spain.
