Abstract

The main objective of this dissertation is to analyze the impact of trade liberalization wich has seen in Brazil in the early 1990's between 1990 to 1996 in the markup of processing industries through three different monetary standards. The specification and methodology adopted in the work are those from Goldar and Aggarwal (2004), which make an analysis of panel data for fixed and random effects for the indian processing industries as a whole and then applying the same tests separating the twenty eight sectors of brazilian manufacturing firms in sectors of capital goods and intermediates in the first group and capital goods in the second. This work also includes applying this methodology, besides the two already mentioned, the test of ordinary leasts square (OLS) to allow better analysis with three different tests before and after separating the sectors through explanatory variables such as import barriers, industry concentration, participation wage, labor productivity, sectoral representation and variation in the rate of production growth in the sector between the years. We conclude that the observed increase in profit margin was impacted significantly by the variables set forth above and these results are important so we can earn that way impacted positively or negatively contributed the profit margin earned by the brazilian manufacturing firms between 1990 and 1996.
