Is Bigger More Efficient? An Empirical Analysis of Scale Economies in Administration in South Australian Local Government*

Abstract

A vast empirical literature has investigated economies of scale in municipal operations, especially in water and wastewater provision as well as domestic waste management. By contrast, comparatively few studies have been conducted on the extent of scale economies in local government administration. Given the stress placed on scale economies in Australian state and territory government policies aimed at the structural reform of local government through municipal mergers, including in South Australian (SA) local government, the absence of empirical research into administrative scale economies is unfortunate. To address this gap in the empirical literature, in this paper, we consider administrative scale economies in the SA local government system using four‐year panel data from 2015–2016 to 2018–2019. We find limited evidence for a relationship between administrative intensity and municipal by population size and for a difference between the administrative intensity of urban and rural councils.
