Local territorial reform and regional spending efficiency

Abstract

We study the effect of a Portuguese structural reform, which reduced the number of parishes, on municipality spending efficiency between 2011 and 2016. We build a composite output indicator and use Data Envelopment Analysis (DEA) to compute efficiency scores. Then, we use a second-stage regression to evaluate the effect of the reform on municipal efficiency after controlling for socio-demographic, political and economic factors. Overall, we find efficiency gains in approximately 10% of municipalities. In some regions (e.g., Alentejo and Centro), more than 50% of the municipalities improved efficiency. The second-stage results show that the structural reform did not improve local spending efficiency in Mainland Portugal, particularly in the Centro, Lisbon and Vale do Tejo regions.
