Privatization of local government services is assumed to deliver cost savings but empirical evidence for this from around the world is mixed. We conduct a meta-regression analysis of all econometric studies examining privatization for water distribution and solid waste collection services and find no systematic support for lower costs with private production. Differences in study results are explained by differences in timeperiod of the analyses, service characteristics, and policy environment. We do not find a genuine empirical effect of cost savings resulting from private production. The results suggest that to ensure cost savings, more attention be given to the cost characteristics of the service, the transaction costs involved, and the policy environment stimulating competition, rather than to the debate over public versus private delivery of these services.
