LOS PRECIOS SOMBRA EN ESPAÑA A PARTIR DEL ANÁLISIS INPUT-OUTPUT

Abstract

This paper presents the description of a methodology based on input-output analysis which permits the estimation of the shadow prices for goods and resources in an economy. Application for Spain is presented as well. The results show that in general shadow prices are different from market prices, and this implies the direct use of the later in social analysis is not valid. Finally, a theoretical proposal to include external effects of production in the initial model is presented.
