Total factor productivity and its components for sheep and goat farms in 37 Southern European regions (2004-2012)

Abstract

[EN] The decline of Southern Europe’s traditional sheep- and goat-farming systems creates a need for studies on the economic determinants that underlie their production processes. Using data from the FADN, we built a panel of 37 regions from 5 countries over an 8-year period (2004–2012). A Cobb-Douglas was specified and a stochastic frontier production was estimated. Total Factor Productivity (TFP) and its components were calculated. The farms have had sustained, positive development of TFP since 2008, with a significant correlation with the labour factor of production. We detected moderate technical progress change, which was accompanied by decreasing efficiency.

[ES] El declive del ovino y caprino del sur de Europa determina la necesidad de estudios sobre su proceso productivo. Con los datos de la FADN se ha elaborado un panel de 37 regiones de 5 países para 2004-2012. A partir de una función Cobb-Douglas, se ha estimado una frontera de producción estocástica; calculando la evolución de la Productividad Total de los Factores (TFP) y sus componentes. Las explotaciones analizadas presentan una evolución sostenida y positiva de la TFP desde 2008 y una correlación con el factor trabajo. Existe un mínimo y creciente progreso técnico y una eficiencia decreciente.
