Abstract

Purpose The purpose of this paper is to examine the effect of external factors on police efficiency in a sample of Peru's municipalities. Drawing on the postulates of the contingency theory of organizations, this study argues that because of the public nature of police organizations' activities, they are heavily influenced by the environment in which they operate, which invariably affects their efficiency. Design/methodology/approach The study examines police efficiency using a four-stage Data Envelopment Analysis model in a sample of 619 Peruvian municipalities ("distritos"). After adjusting the inputs to the external environment, the remaining inefficiencies are presumed to result from managerial issues and other internal organizational factors. Findings The results indicate that police efficiency improves after adjusting police inputs to the effect of external factors. The mean efficiency scores improved by 39 percent from 0.57 to 0.79. Because the effects of the external environment can be stronger in larger municipalities, these experience larger improvements in efficiency than smaller municipalities. Originality/value This study introduces a new and innovative methodological approach to measure police performance. This multi-stage approach has not been used in the context of democratic policing in Latin America and the Caribbean. The current research fills an important gap on how to measure police performance in developing countries.
