Disaggregation of sectors in social accounting matrices using a customized Wolsky method

Abstract

The aim of this work is to enable the implementation of disaggregation processes for specific and homogeneous sectors in Social Accounting Matrices (SAMs), while taking into account the difficulties in data collection from these types of sectors. The method proposed is based on the Wolsky technique, customized for the disaggregation of SAMs, within the current-facilities framework. The Spanish SAM for 2008 is used as a benchmark for the analysis, and the specific sector chosen for disaggregation is that of the Spanish Optical Sector.

Notes

¹ The increasing importance of quantifying medical-manufacturing sectors in order to better develop policy measures and the high specialization of these types of sectors, classified as high-technology sectors, makes ophthalmic-optics highly suitable for this analysis.
