Dinâmica da concentração de mercado na indústria Brasileira, 1996-2003

Abstract

ResumoO objetivo desse trabalho é estudar a mudança na concentração dos mercados da indústria brasileira de mineração e transformação entre 1996 e 2003, realizando uma decomposição do índice de Herfindahl-Hirschman em variação da distribuição do tamanho e do número de empresas. Os resultados obtidos sugerem que, na média, a indústria sofreu reduzida mudança no período; contudo, apontam que, em um grupo de indústrias, as mudanças no nível de concentração foram substanciais. Indicam também que a maior responsabilidade por essas mudanças está associada a alterações na desigualdade do tamanho, apesar de o período ter presenciado um forte movimento de entrada de novas empresas em diversos segmentos industriais.Palavras-chave: Concentração de mercado; Indústria brasileira; Índice de Herfindahl-Hirschman; Brasil; Decomposição.

The paper decomposes the Herfindahl-Hirschman index into variations in the size distribution and the number of firms. The results show that the average concentration did not change greatly in the period analyzed; however, a small group of industries showed significant differences in concentration. In these cases, changes in size distribution appear to have more importance than changes in the number of firms.

Industrial determinants of anti-dumping in Brazil – Protection, competition and performance: An analysis with binary dependent variable and panel data

“…Amann and Baer (2008) realized that the economic reforms (liberalization/privatization) of the 1990s, under the aegis of neoliberal policies, allowed the exposure of the Brazilian economy to domestic and international market forces, but paradoxically increased the concentration of the ownership of the firms. Using a database and a similar period to that of this work, Rocha (2010) studied the concentration of Brazilian industrial markets between 1996 and 2003, using the decomposition of the Herfindahl-Hirschman Index (HHI), concerning size and the number of companies. On the average, the industries suffered little variation.…”

“…Concentration measures are used to analyze the market structure and highlight the dimension of competitiveness. These indicators summarize in a concept of multiple dimensions, such as supply and demand, technological capacity, cost structure, and others (COELHO JUNIOR et al, 2013;POSSAS, 1999;ROCHA, 2010).…”
