Como se mede uma onda?: mensurando a renovação na Câmara dos Deputados brasileira

Abstract

This study aims to contribute methodologically to the Brazilian literature on parliamentary renewal by investigating whether the measures used to assess renewal point to the same phenomenon or not. Using data available from the Brazilian Electoral Court (TSE) for the Federal Deputy elections in Brazil from 2014 to 2022, we conducted an exploratory data analysis and exploratory factor analysis to measure the variance among the variables that compose the phenomenon of parliamentary renewal and to determine if these measures can be summarized into a single factor. It is important to emphasize that the hypothesis of this study posits that the variables cannot be reduced to just one factor. As a main result, we found that the measures can be reduced to a single factor, with the construction of this factor being more closely related to the Gross Renewal Rate than the other measures. Therefore, as these measures can be summarized into one factor, they indicate to mesuare the same phenomenon, contradicting our hypothesis. Thus, it is expected that this research can provide a theoretical and methodological contribution to the study of parliamentary renewal in Brazil.
