Concentração de mercado: uma análise do setor de tratores agrícolas no Brasil

Abstract

The purpose of this paper is to analyze the concentration in the domestic market of wheel tractors from 1999 to 2010. For this, bibliographical research in secondary sources, the information obtained was substantial for defining the relevant market, database and analysis of barriers to entry in the industry. After this we calculated the rates of concentration ratio and and Herfindahl-Hirschman (HH) using data from the national domestic sales of wheeled tractors targeted power, provided by the National Association of Automotive Vehicle Manufacturers (ANFAVEA). The results showed that even before the mergers during the period, few companies were included in the market and there are major barriers to entry for the industry, but it continues to compete on price. As the index of concentration ratio does not take into account the relative share of each firm, so the movement of the market did not significantly affect the . Similar to previous studies, it was demonstrated that the tractor industry can be characterized as an oligopolistic production structure.
