Una aproximación al sesgo de medición del precio de las computadoras en México

Changes in quality in information technology products provoke that compilation of their price indexes represent a major challenge. In this respect, the aims of this study are three. First, to build price indexes for personal computers during 1990-2004. Second, to compare our price indexes with those compiled by the Mexican Central Bank, the Spanish National Institute of Statistics, and the Bureau of Labor Statistics. And finally, to explore the viability of transfer hedonic functions between countries. Our results show a 21% average decline of the PC price index during the analyzed period. In consequence, official price index related to computers has a measurement bias. The adjusted CPI implies that the inflation rate was 4.425%, and not 4.463% as was established by the Central Bank between July 2003 and December 2004.
