| Popis: | This study aimed to analyze the dynamics of concentration and inequality of Brazilian exports of chemical cellulose. Secondary data of value and quantity of Brazilian exports were used, comprising the period between 1990 and 2010. Using this data, the following indexes have been calculated: concentration ratio (CR4 and CR8), Herfindahl-Hirschman Index (HHI) and Gini. For the Gini index of inequality and the concentration ratios CR4 and CR8, the years 2001, 2002 and 2003, respectively, marked the end of the downfall levels of inequality and concentration. The HHI had a similar behavior, but in 2006 presented the lowest value. Thereafter, the rates tended to increase but did not reach the levels of the beginning of the period. Overall, the results showed a decrease in the export concentration as well as an increase in the number of trading partners. There was also an increase in the amount exported, as well as in the volume and unit price, during the period. The calculated indexes are variables associated with the ability of industry competition and based on the results they indicate that the national pulp became more competitive over time. |
