Beginning in the 1980s, 3 basic limitations were indicated: 1 its tendency toward increasing measurement imprecision in parallel with the increase in the number of sectors or branches compared; 2 its methodological weakness when attempting prospective predictions Bartels, William and Duijn, 1982; and 3 its inadequacy in comparing the value of an economic magnitude at 2 time points initial and final without considering any additional information within the period investigated Mayor et al., 2005.
Desde la década de los ochenta del siglo pasado se indicaban tres limitaciones básicas: 1 se advertía que a mayor número de sectores o ramas comparadas mayor imprecisión derivada, 2 se señalaba la debilidad del método al momento de realizar intentos prospectivos Bartels, William y Duijn, 1982 y 3 se consideraba simplista por comparar el valor de una magnitud económica en dos instantes temporales inicial y final sin considerar ninguna información adicional al interior del periodo de tiempo investigado Mayor et al., 2005.
