Título: Productivity Measurement in Radial DEA Models with Multiple Constant Inputs

Ponentes: C. A. KNOX LOVELL (University of Queensland)

Lugar: Sala de Seminarios del Instituto Universitario de Investigación CIO, Edificio Torretamarit

Resumen:

We consider productivity measurement based on radial DEA models with multiple constant inputs. We show that in this case the Malmquist and the Hicks-Moorsteen productivity indices coincide and are multiplicatively complete, the choice of orientation for the measurement of productivity change does not matter, and there is a unique decomposition of productivity change containing two independent sources, namely technical efficiency change and technical change. Technical change decomposes in an infinite number of ways into a radial magnitude effect and an output bias effect. We also show that the aggregate Malmquist productivity index is given by the geometric mean between any two periods of the simple arithmetic averages of the individual contemporaneous and mixed period distance functions.
