    Abstract: This article makes a quick review of the arguments that link the theoretical body of General Theory to the apparatus of imperfect competition - both those that Keynes had a chance to respond to, and some that were recovered many years later. The aim here is to defend a crucial point: Keynes's results did not depend on "microfoundations", understood as the definition of particular market structures. It is intended to show that Keynes, when confronted with the suggestion to use an imperfect competition apparatus to base his results, strongly rejected this possibility, showing that the definition of a specific market structure is not necessary to support his arguments.

    Resumo: Este artigo faz rápida revisão dos argumentos que ligam o corpo teórico da Teoria Geral ao aparato de concorrência imperfeita - tanto os que Keynes teve chance de responder, quanto alguns que foram recuperados muitos anos depois. O que se quer, aqui, é defender um ponto crucial: os resultados de Keynes não dependiam de “fundamentos microeconômicos”, entendidos como a definição de estruturas de mercado particulares. Pretende-se mostrar que Keynes, ao ser confrontado com a sugestão de utilizar um aparato de competição imperfeita para fundamentar seus resultados, rejeitou fortemente esta possibilidade, mostrando não considerar necessária, para a sustentação de seus argumentos, a definição de uma estrutura de mercado específica. Mais tarde, várias críticas feitas à Teoria Geral em seu berço foram retomadas.
