Evolución de precios y de volumen de la industria manufacturera. Período 1982-2008.Documento metodológico.

Despite the Instituto Nacional de Estadística (INE) in Uruguay has calculated and published disaggregated data on real manufacturing production index since 1982 –the Volume Index–, the methodological changes that took place in 1988, 2002 and 2006 determined that the resulting subsets of data are not fully comparable, thus preventing the use of complete time series. These differing criteria in building the volume and price index relate to using diverse definitions of the relevant value of production (including or not taxes, eg) and production units (establishments versus firms), as well as to the use of distinct classifications of manufacturing industries (Revisions 2 and 3). Here we propose a methodology for constructing 1982-2009 compatible constant-prices disaggregated production index as well as price index, using both Paasche and Laspeyres formula.
