Service provision by local governments can be delivered using in-house bureaucracies, private firms, and partnerships with other governments or the not-forprofit sector. This production decision has been a major focus of discussion among scholars, practitioners and political agents for the last quarter of a century. The transaction costs framework is an important tool to analyse decisions regarding the production of local services. In this paper, the authors employ this framework to analyse service delivery in Portugal and find that service characteristics and the local political environment play a key role in local officials' choice among the three governance mechanisms to deliver public services.
KEY WORDS: Service delivery, transaction costs, governance mechanismsDue to their level of proximity and periodic transfers of competences from the national government, local governments in Portugal gained importance over the past two decades as service providers. Their functional responsibilities have been extended significantly over several areas including water supply, promotion of regional development, solid waste collection, emergency management, health care, education, and land use management, among many others. To cope with all these challenges, local governments changed from a general, multi-purpose organisation to a complex network of relationships with other public bodies, private agents, and not-for-profit organisations.
