Query: Industrial Concentration of the Brazilian Automobile Market and
  Positioning in the World Market   This paper surveys the evolution of industrial concentration of the Brazilian
automotive market as well as its positioning in the worldmarket. Data available
by OICA (International Organization of Motor Vehicle Manufacturers) were used
to better understand the characteristics of the Brazilian market on the world
stage. A cluster analysis algorithm (by the k-means technique) ranks Brazil
with a concentration profile in a group of countries like US and South Korea,
in contrast to countries such as Germany, Canada and Japan, or even France and
Italy. It is rather usual to characterize the market structure through
industrial concentration indices: we revisit CR ratios (concentration ratios),
HHI (Herfindahl-Hirschman index), B (Rosenbluth index), and CCI (Horvath
comprehensive concentration index). Data of Anfavea-Brazil (Associacao Nacional
dos Fabricantes de Veiculos Automotores) were used to estimate these indices in
the period 2012-2018 for the national automobile industry. The values obtained
indicate that by 1998 the automotive sector was behaving as an
oligopoly-differentiated. However, the values of more recent periods
(particularly CR4) strongly indicate that the sector is currently moderately
concentrated and is changing for a quasi-devolved market.
