Abstract
As a contribution to the academic debate on the use of outsourcing as a formula for the provision of local public services, the article proposes to focus attention on political-institutional factors. The paper departs from the review of the main arguments highlighted by the literature and it contrasts their expected results in cross-sectional study based on data from all the municipalities with over 5,000 inhabitants in Catalonia, a Spanish Autonomous Community. A typology of municipalities is constructed through principal component analysis and a cluster analysis and the existence of differences in the percentage of outsourcing among types of municipalities is tested. The results show the relevance of political-institutional factors in the selection of the service provision formula and allow us to identify three strategies that propose outsourcing as a mechanism of flexibility of public management.
