Competition policy evaluation through damage estimation in fuel retail cartel
Conteúdo do artigo principal
Resumo
Este trabalho estima os danos causados pelo cartel nos postos de gasolina na regiao sul do Brasil usando tanto uma equacao reduzida quanto um modelo estrutural de demanda e oferta. Documentos do Conselho Administrativo de Defesa Economica (CADE) ajudam a caracterizar os postos envolvidos na colusao nos mercados de etanol e gasolina. O objetivo é avaliar os efeitos da politica de concorrencia comparando o montante do dano estimado com as multas aplicadas.Em adicional, esse trabalho tambem
contribui para a literatura sobre substituicao de gasolina, uma vez que os dados apontam que o etanol é percebido como substituto perfeito e é preco inelastico. Os resultados mostram que houve um sobrecusto causado pelo cartel de ordem de 4.6% a 6.6% no mercado de gasolina e de ate 12% no mercado de etanol. As multas aplicadas, contudo, devem considerar a probabilidade de o cartel ser descoberto e, dada sua baixa probabilidade, as multas aplicadas no presente caso parecem estar alinhadas com esse objetivo.
