Previous issue date: 2011-07-26 / Esta tese tem como objetivo principal aproximar a evidencia empirica existente sobre os agregados macroeconomicos com as novas evidencias empiricas baseadas nos micro dados de precos ao consumidor, tendo como base os modelos padroes de rigidez de preco utilizados na literatura de politica monetaria. Para isso, esta tese utiliza a base de dados individuais de precos ao consumidor no Brasil fornecida pela Fundacao Getulio Vargas. Especificamente, esta tese foca em tres temas principais: a existencia de variac˜oes temporararias de precos, a heterogeneidade na rigidez de precos entre firmas de um mesmo setor e o formato das func˜oes hazard. Os resultados mostram que: existe de fato uma correlac˜ao entre as variaveis referentes as mudancas temporararias de precos e os agregados macroeconomicos; a heterogeneidade na rigidez de precos entre firmas de um mesmo setor apresenta efeitos significativos sobre a dinamica dos agregados macroeconomicos; e por fim, o formato mais geral da func˜ao hazard proposta nesta tese possibilita novas dinamicas dos agregados macroeconomicos. / This thesis has as its main goal to approximate the existing empirical evidence on macroeconomic aggregates with the new empirical evidences based on micro data on consumer prices, having as a baseline the standard sticky-price models used in the literature on monetary policy. In order to do that, this thesis makes use of a micro data on individual consumer prices in Brazil published by Getulio Vargas Foundation. Specifically, this thesis focus on three main issues: the existence of temporary price changes, the within-sector heterogeneity in price stickiness and the shape of hazard functions. The results show that: there exist a correlation between variables on temporary price changes and macroeconomic aggregates; the within-sector heterogeneity in price stickiness has significant effects on macroeconomic dynamics; and the more general specification of the shape of the hazard function that is proposed in this thesis leads to new dynamics for the macroeconomic aggregates.
