For such purpose, it was made an compulsory literature review of each studied "school", dealing with the main concepts and discussing their interpretation about the crises of capitalism. Finally, on the last chapter, it were discussed the impressions of each "school" on perceptions of capitalist mode of production, the institutions which will form socioeconomic structures and policies, besides the discussion on technical progress. These considerations bring the thoughts of the schools on the study of the crises of capitalism as well as the role of institutions in observed changes in recent economic history to resume profit rates. Therefore, it was realized that the arguments used to understand the crisis of the 1970s and its implications for the world economy from the perspective of Regulation Theory and Social Structure of Accumulation Theory, they had already been indicated by Ignacio Rangel since the early 1940s, from his considerations about Brazil. / Esta disserta??o tem por objetivo investigar as aproxima??es conceituais e as diverg?ncias existentes entre tr?s escolas do pensamento econ?mico contempor?neo, a saber: a Escola da Regula??o, a escola da Estrutura Social de Acumula??o e Ign?cio Rangel. Para tanto, foi feito uma revis?o da literatura basilar de cada escola estudada, abordando os principais conceitos e discutindo sua interpreta??o sobre as crises do capitalismo. Por fim, no ?ltimo cap?tulo, foram abordadas as impress?es de cada escola sobre as percep??es do modo de produ??o capitalista, quais as institui??es que ir?o compor as estruturas socioecon?micas e pol?ticas, al?m, da discuss?o sobre progresso t?cnico. Estas considera??es trazem as reflex?es das escolas no estudo das crises do capitalismo, bem como o papel das institui??es nas mudan?as observadas na hist?ria econ?mica recente para retomar as taxas de lucro. Percebeu-se, portanto, que os argumentos utilizados para compreender a crise da d?cada de 1970 e seus desdobramentos na economia mundial, a partir da ?tica da Escola da Regula??o e da Estrutura Social de Acumula??o j? haviam sido apontados por Ign?cio Rangel desde o in?cio da d?cada 1940, a partir de suas considera??es sobre o Brasil.
