Abstract

Este artigo considera o conjunto dos mercados portugueses e calcula uma nova medida de concorrência sugerida por Boone (2008), a qual se baseia no conceito de elasticidade do lucro face aos custos marginais num dado mercado. O artigo conclui que a maioria dos mercados apresentou uma redução da concorrência no período 2000-2009, apesar de existir uma grande heterogeneidade. Além disso, os mercados que apresentaram reduções da concorrência representam a grande maioria das vendas, do valor acrescentado bruto e do emprego na economia portuguesa. O setor não-transacionável apresenta níveis de concorrência mais baixos do que o setor transacionável. Adicionalmente, as reduções da concorrência são relativamente generalizadas nos mercados de ambos os setores, mas em termos de vendas, valor acrescentado bruto e emprego são mais substanciais no setor não-transacionável.
