Urban concentration in Latin America. relationships between microcephaly and fiscal decentralization

The document presents an account of the main theoretical models of fiscal decentralization and its impact on the demographic composition of the regions in each country, contrasting it with urban primacy and macrocephaly theories, with a special emphasis on their incidence in Latin America.Through data analysis and literature review, it was found that the incidence of public spending and subnational taxation on the reduction of urban primacy was only statistically significant in countries outside the Latin American context, which reinforces the call to deepen the understanding of this phenomenon and the construction of theoretical and analytical models that lead to a more efficient decentralized public expenditure that contributes to the reduction of urban primacy in Latin America.
