A spatial model based on the endogenous growth theory for Portugal. Another approach

We built a model analyzing, through cross-section estimation methods, the influence of spatial effects in the conditional product convergence in the parishes’ economies of mainland Portugal between 1991 and 2001 (the last year with data available for this spatial disaggregation level). Taking into account the estimation results, it is stated that there are not indications of convergence (the population is in the littoral of Portugal) and it can be seen that spatial spillover effects, spatial lag (capturing spatial autocorrelation through a spatially lagged dependent variable) and spatial error (capturing spatial autocorrelation through a spatially lagged error term) condition the convergence of product of Portuguese parishes in the period under consideration.
