Why do local governments privatise public services? A survey of empirical studies

Many empirical works have been devoted to analysing the factors explaining local privatisation. Overall, most of the empirical analyses have low explanatory power due to the methodological difficulties in capturing the dynamic nature of the privatisation decision. The variables most often considered are those related to fiscal stress and cost reduction and political processes and ideological attitudes. Our review indicates that fiscal stress and pressure from interest group are explanatory factors of local privatisation in those early studies devoted to the US that consider a broad range of services. Furthermore, cost considerations seem to be taken into account by local governments, particularly when scale economies and transaction costs are taken together. Finally, ideological attitudes of policy makers do not seem to influence local service delivery choices in any systematic way.
