Centralidade em redes de trabalho e diferenciais salariais entre ocupações no Brasil

Abstract

Social networks of individuals enable them to perform various interactions with their peers. Such networks, as well as the position that an individual occupies on it, are of great importance to their professional success and the impact that networks have on the behavior of firms and workers motivates researches on this field. This study seeks to identify the connections between individuals from the Brazilian labor market, as well as the identification of the measure of centrality of some workers in their respective networks. Thus, it is possible to identify the relative importance that an agent has compared to their peers in his network through a new measure of centrality that takes into account the individual's working time and their peers linked to the same network. Through this identification, you can then relate this fact to other individual characteristics, focusing mainly on the analysis of the how the degree centrality of an agent can influence the income earned by individuals. From the Annual Social Information Report data (RAIS) for the years 2008 to 2013 arising from the Ministry of Labor and Employment of the Brazilian government, the main results indicates that the relevance of a worker in his network, measured by the centrality index proposed in this study, is important to explain the wage gap in the labor market.
