The paper presents a framework for determining the optimal size of local jurisdictions and whether it varies depending on the geographical heterogeneity of the territory. To that aim, it first develops a theoretical model of cost efficiency that takes into account spatial interactions and spillover effects among neighbouring jurisdictions. The model solution leads to a spatial Durbin panel data specification of local spending as a non-linear function of population size. The model is tested using a large local data set over the period 2003-11 for an aggregate measure of public spending. The empirical findings suggest a 'U'-shaped relationship between population size and the costs of providing public services. A second step investigates the role of geographical characteristics such as elevation and terrain ruggedness in the determination of the optimal jurisdiction size. The results reveal that optimal city size decreases with elevation and increases with ruggedness.

Abstract

The paper presents a framework for determining the optimal size of local jurisdictions and whether it varies depending on the geographical heterogeneity of the territory. To that aim, it first develops a theoretical model of cost efficiency that takes into account spatial interactions and spillover effects among neighbouring jurisdictions. The model solution leads to a spatial Durbin panel data specification of local spending as a non-linear function of population size. The model is tested using a large local data set over the period 2003-11 for an aggregate measure of public spending. The empirical findings suggest a 'U'-shaped relationship between population size and the costs of providing public services. A second step investigates the role of geographical characteristics such as elevation and terrain ruggedness in the determination of the optimal jurisdiction size. The results reveal that optimal city size decreases with elevation and increases with ruggedness.
