Productivity Growth in the Lisbon Police Force

Abstract

This paper estimates total productivity change with regard to the Lisbon Police Force and decomposes it into technically efficient change and technological change with data envelopment analysis (DEA). The benchmarking procedure implemented is an internal benchmarking, in which police precincts are compared against each other. The aim of this procedure is to seek out those best practices that will lead to improved performance throughout the whole force. We rank the precincts according to their total productivity change for the period 2000–2001, concluding that some precincts experienced productivity growth while a small number experienced productivity decrease. Economic implications arising from the study are considered.
