- Measuring the Technical Efficiency of Airports in Latin America and the Caribbean
Sergio Perelman (Université de Liège) Co-authors: Tomas Serebrisky Abstract: This paper studies the technical efficiency and its determinants of airports in Latin America (LAC). The evolution of productive efficiency in the LAC Region has seldom been studied, mainly due to lack of publicly available data. Relying on a unique dataset that was obtained through questionnaires distributed to airport operators, we use Data Envelopment Analysis (DEA) methods to compute an efficient production frontier and compare the technical efficiency of LAC airports relative to airports around the world. In a second stage we estimate a truncated regression to study the drivers of observed differences in airport efficiency. According to our results, institutional variables (private/public operation), the socioeconomic environment (GDP level) and airport characteristics (Hub, share of commercial revenues) matter to explain airport productive efficiency. Finally, we also estimate total factor productivity changes for LAC airports for the period 1995-2007. LAC is a region that has implemented a wide variety of private sector participation schemes for the operation of airports since the mid 90s. Our results show that private operators have not had higher rates of total factor productivity change.
