Brazilian Journal of Political Economy, 1995, vol. 15, issue 4, 536-546

Abstract: This article resumes the author’s Ph.D. thesis main aspects and results. It presentsan algorithm which enables one to measure sectorial mark-ups variations not usingaccounting data from firms. That instrument has the capability of discounting the impact ofvariations in relative prices and in productivity for inputs, from the variation of final pricesof sector. The testing of the algorithm revealed a clear positive correlation between mark-upvariations and degree of industrial concentration, higher and more significant in the recessionperiod (1980-1983) than in the growth one (1977-1980). JEL Classification: E31; C67.
