BROWN, Flor  and  DOMINGUEZ, Lilia. Industrial Perfomance Measuremement in Mexico: a methodological perspective. Inv. Econ [online]. 2002, vol.62, n.239, pp.37-73. ISSN 0185-1667.

This paper aims to shed light on the different theoretical interpretations of the profit rate and profit margin used in modern economics and to examine the degree to which disparities in the estimations are due to differences in the method selected for Mexican manufacture in the period between 1993 and 1997 for 185 industrial classes. We estimated four measures of industrial performance. These estimates were tested with paired sample T Test and Kendall Concordance test. Our results revealed that there are important differences between methods of estimation of profit rate in levels, growth rates and orderings. Therefore it is not valid to compare results of different studies when they use different methods of estimation of profit rates.
