The main porpose of this study was to identify the contribution of the worker, firm and region's effects, focusing on the density of employment as a measure of agglomeration, on the wage differential in the Brazilian regions in the period from 2010 to 2014. The analysis was made in panel , from RAIS data, which allows the monitoring of the individual over time. Initially, mincerian equations applied to OLS models were estimated, with analysis focused on fixed effects results. Afterwards, the analysis was extended to a model involving variables interaction, to verify the explanatory potential of agglomerations. Finally, the regression method was applied by instrumental variables in order to eliminate the possible endogeneity of the employment density. The results indicated that there is a wage differential, although small attributed to the density of employment, according to the literature. It has been found that education, the sector which the worker is inserted, and the size of the firm have a strong influence on wage differentials, especially higher level individuals, those working in industry and those working in larger firms. In addition, the interactions showed strong effects on wages. Finally, it is concluded that the density of employment, characteristics of individuals, firms and region, separately and through interactions, contribute to the existence of wage differentials.
Diferenciais salariais: uma análise do setor industrial do Nordeste brasileiro para o período de 2010 a 2014

The theme of wage differentiation is often addressed in studies in economics and can be analyzed from spatial characteristics, individuals and firms. In analyzing the impact of firm characteristics on workers 'wage returns, a number of characteristics relating to the institutions' physical and financial structures should be related, as shown in the literature that characteristics of the different industries to which workers are inserted constitute an important factor of wage determination. Thus, this paper aims to analyze the wage differentiation existing in the industrial sector of the Northeast of Brazil, seeking to verify the characteristics of the industries that pay the highest and the lowest wage premiums; as well as to analyze if the unobservable characteristics of individuals influence the existing wage dispersion. Using the RAIS database, a model is estimated from mincerian income equations. The analysis is done comparing the wage premiums obtained in the regressions of the ordinary least squares (OLS) model and the fixed effects of individuals. The results show that the individual fixed effects are important components to explain the real wage variations of the formal worker of the Northeastern industry, between 2010 and 2014.
Prêmio salarial urbano x prêmio de migração: uma análise para os trabalhadores brasileiros

The Brazil, being a country with a large territorial dimension and strong socio-cultural and economic characteristics, has in migration a current and significant fact. Faced with this, many researchers have been motivated to analyze the nature of migration and its impact on the regional economic sphere as well as on the national economic sphere. Santos and Ferreira (2007) verified that interstate migrants are positively selected, that is, they have better unobservable characteristics than non-migrants. In addition, in recent years, several studies are being designed to locate a wage premium in large urban centers in order to verify the existence of an additional gain in the productivity of individuals due to the phenomenon of migration to these locations. In this sense, this paper proposes to investigate the relationship between migration and the wage premium of Brazilian workers and its impacts on the structure of wage differentials, as well as to analyze the effect of size of urban centers in determining the wage premium of these workers. To do this, RAIS-MTE data will be used between 2010 and 2014, where the main advantage is the longitudinal monitoring of individuals, besides allowing the control of the selection problem, when including the fixed effect. Thus, by including the fixed effects in our analysis, it is possible to capture the effect of selection and the process of adjustment among migrants. The results point to wage gains in favor of the migrant individual, although these are reduced when controlled by observable and unobservable characteristics of workers, which would be associated with the influence of urban centers on worker productivity.
