Discriminação salarial por cor e gênero revisitada: uma abordagem de decomposição contrafactual utilizando regressões quantílicas

A desigualdade salarial, especialmente a resultante da discriminação contra negros e mulheres no mercado de trabalho, é um componente importante da elevada concentração de renda da economia brasileira. Ao contrário da grande maioria dos trabalhos já desenvolvidos nesta área, este trabalho não adota a hipótese de que os efeitos de atributos determinantes do salário são constantes e idênticos para os indivíduos ao longo da distribuição de renda. São estimadas as estruturas salariais para cada percentil da distribuição salarial para homens brancos, homens negros, mulheres brancas e mulheres negras utilizando a técnica de decomposição contrafactual por regressões quantílicas, proposta por Koenker e Bassett (1978) e desenvolvida por Machado e Mata (2004). Isto proporciona uma compreensão mais detalhada e abrangente dos fatores que determinam a remuneração do trabalho para diferentes níveis de renda e fornece uma medida mais completa do grau de discriminação contra os negros e mulheres no mercado de trabalho ao longo da distribuição salarial. Para os três grupos, a discriminação é crescente em relação à posição na distribuição salarial, indicando a dificuldade de se atingir posições melhor remuneradas no mercado de trabalho por parte de mulheres e negros. A discriminação afeta principalmente as mulheres negras, seguidas das mulheres brancas e dos homens negros. Para os homens negros, a discriminação é baixa entre os mais pobres e cresce nos níveis mais altos da distribuição. As mulheres brancas sofrem ao longo de toda a distribuição com maior efeito entre os 15% mais ricos. As mulheres negras sofrem com a discriminação por cor e gênero, estando assim na pior situação entre os grupos. A remuneração da educação estimada para os quatro grupos indica ganhos crescentes conforme a posição na distribuição salarial ampliando a desigualdade salarial intra-grupo, adicionalmente, observa-se uma desvalorização da educação dos negros de ambos os sexos na determinação salarial e que as mulheres sofrem algum tipo de discriminação no que diz respeito à educação apenas nos níveis salariais mais elevados. Os ganhos salariais obtidos com a equalização da escolaridade e formalização entre os grupos discriminados e os homens brancos indicam que, no caso da educação, homens e mulheres negros teriam ganhos ao longo de toda a distribuição, com ênfase entre os mais ricos. Para a formalização, a população nos decis inferiores da distribuição salarial seria a principal beneficiada.

Racial discrimination in Brazil: interviews with leaders of the black movement

Racism in Brazil has some specificities when compared to other countries, for, differently from, for instance, South Africa and the United States, Brazilian Constitutions, ever since the Independence (1822), have never distinguished the citizens according to race or color. Furthermore, since the mid-1900s, Afro-Brazilian cultural manifestations, such as, for example, samba and capoeira, started to be valued as a part of our “national identity”. These specificities make race relations in Brazilian society a much more complex issue. This paper is focused on selected parts of interviews that deal with the nature of racial discrimination in Brazil, extracted from interviews with leaders of the black movement produced within the scope of the project “The History of Black Movement in Brazil: organization of a collection of Oral History Interviews”, developed by CPDOC, Getulio Vargas Foundation (Rio de Janeiro). These “histories within history”, as told by our interviewees, may be transformed into images that will be able to condense a given reality, thus allowing us to evaluate the gains obtained by oral history methodology.

Occupational tasks and changes in the wage structure

This paper argues that changes in the returns to occupational tasks have contributed to changes in the wage distribution over the last three decades. Using Current Population Survey (CPS) data, we first show that the 1990s polarization of wages is explained by changes in wage setting between and within occupations, which are well captured by tasks measures linked to technological change and offshorability. Using a decomposition based on Firpo, Fortin, and Lemieux (2009), we find that technological change and deunionization played a central role in the 1980s and 1990s, while offshorability became an important factor from the 1990s onwards.

Trade Liberalization and Regional Impacts on Residual Wage Inequality: Evidence from Brazil

O objetivo deste trabalho é entender mais sobre o papel da liberalização sobre a desigualdade salarial, mais precisamente, sobre a desigualdade residual dos salários. Usando a abertura comercial brasileira, a extensa redução tarifária que ocorreu entre 1987 e 1995, é investigado empiricamente se os diferentes níveis de exposição ao comércio entre os estados contribuíram para os diferentes movimentos da desigualdade. Os resultados indicam que estados mais expostos à liberalização comercial experimentaram um aumento relativo da desigualdade residual dos salários ou, de forma equivalente, uma menor redução. Estes resultados enriquecem a discussão dos efeitos da abertura comercial sobre a desigualdade.

The role of profits in wage determination: evidence from US manufacturing

We estimate the effect of firms' profitability on wage determination for the American economy. Two standard bargaining models are used to illustrate the problems caused by the endogeneity of profits-per-worker in a real wage equation. The profit-sharing parameter can be identified with instruments which shift demando Using information from the input-output table, we create demand-shift variables for 63 4-digit sectors of the US manufacturing sector. The LV. estimates show that profit-sharing is a relevant and widespread phenomenon. The elasticity of wages with respect to profits-per-worker is seven times as large as OLS estimates here and in previous papers. Sensitivity analysis of the profit-sharing parameter controlling for the extent of unionization and product market concentration reinforces our results.

The effects of the minimum wage on earnings and employment in Brazil

This paper analyzes the effects of the mlmmum wage on both, eammgs and employment, using a Brazilian rotating panel data (Pesquisa Mensal do Emprego - PME) which has a similar design to the US Current Population Survey (CPS). First an intuitive description of the data is done by graphical analysis. In particular, Kemel densities are used to show that an increase in the minimum wage compresses the eamings distribution. This graphical analysis is then forrnalized by descriptive models. This is followed by a discussion on identification and endogeneity that leads to the respecification of the model. Second, models for employment are estimated, using an interesting decomposition that makes it possible to separate out the effects of an increase in the minimum wage on number of hours and on posts of jobs. The main result is that an increase in the minimum wage was found to compress the eamings distribution, with a moderately small effect on the leveI of employment, contributing to alleviate inequality.

The firm size wage premium : a quantile analysis

Empirical evidence shows that larger firms pay higher wages than smaller ones. This wage premium is called the firm size wage effect. The firm size effect on wages may be attributed to many factors, as differentials on productivity, efficiency wage, to prevent union formation, or rent sharing. The present study uses quantile regression to investigate the finn size wage effect. By offering insight into who benefits from the wage premi um, quantile regression helps eliminate and refine possible explanations. Estimated results are consistent with the hypothesis that the higher wages paid by large firms can be explained by the difference in monitoring costs that large firms face. Results also suggest that more highly skilled workers are more often found at larger firms .

Regulation and wage adjustment patterns : non parametric evidence from longitudinal data

This paper gives a first step toward a methodology to quantify the influences of regulation on short-run earnings dynamics. It also provides evidence on the patterns of wage adjustment adopted during the recent high inflationary experience in Brazil.The large variety of official wage indexation rules adopted in Brazil during the recent years combined with the availability of monthly surveys on labor markets makes the Brazilian case a good laboratory to test how regulation affects earnings dynamics. In particular, the combination of large sample sizes with the possibility of following the same worker through short periods of time allows to estimate the cross-sectional distribution of longitudinal statistics based on observed earnings (e.g., monthly and annual rates of change).The empirical strategy adopted here is to compare the distributions of longitudinal statistics extracted from actual earnings data with simulations generated from minimum adjustment requirements imposed by the Brazilian Wage Law. The analysis provides statistics on how binding were wage regulation schemes. The visual analysis of the distribution of wage adjustments proves useful to highlight stylized facts that may guide future empirical work.

Wage inequality and trade liberalization : evidence from Argentina

Wage inequality has increased substantially in Argentina during the nineties. At the same time during this decade Argentina has gone through a rapid and deep process of trade liberalization. In this paper we try to associate both phenomena. In particular, we attempt to answer the following question: Did trade liberalization play any role in shaping the argentine wage structure during the period studied? Specifically, we test whether those sectors where import penetration deepened are also the sectors where, ceteris paribus, a higher increase in wage inequality has taken place. We fmd evidence that supports this hypothesis.
