This paper analyse the role played by fiscal equalisation schemes in determining sub-national borrowing. They test econometrically the link between the regional government primary fiscal balances and the GDP per capita in Canada, Germany and Spain. The authors find that either poor or rich regions can display higher regional public borrowing on average and explain how these results can be linked to the institutional design of regional equalisation systems in place in these countries. Particularly, elements such as tax effort and fiscal capacities play a relevant role in this regard. Reforms of these schemes can therefore prove instrumental in reducing regional heterogeneity in public borrowing.
