This paper is concerned with the estimation of productivity and technical progress based on DEA applied to complete panel data (intertemporal-DEA). Instead of assuming unchanged technology, this paper presents a formulation of technical change that allows the decomposition of productivity scores...

A new procedure for the measurement of efficiency and technical change is presented, using DEA with three-dimension data (box data), pooling over sectors, regions and time. Until now, when pooling the data in panel applications it has been assumed that technology remained unchanged, so...

Productivity growth for the agricultural sectors of the 17 Spanish regions over the period 1977-88 is studied using non-parametric programming techniques. Productivity changes based on conventional inputs are linked to other economic, geographic and institutional issues. Average technical change...

En este trabajo se realiza un análisis comparado de dos métodos no paramétricos de medida de productividad total de los factores con datos de panel basados en programación: índices de Malmquist y un modelo DEA intertemporal que permite acotar las medidas de eficiencia y progreso técnico,...

This study analyses seafood consumption at home in Spain using three different cross-sectional survey data-sets for 1980, 1990 and 1998. Households are analysed in eleven different types, according to size and composition. Price indices for seafood and meats are calculated for each household...
