Central no debate sobre o aumento da concentração de renda entre os anos 60 e 70 no Brasil, o papel da estrutura produtiva na determinação da distribuição de salários ficou relegado a segundo plano na literatura econômica das últimas décadas. Ao resgatar tais elementos para a análise da relação entre a redução da desigualdade salarial e as alterações na composição do emprego no Brasil no período recente, contribuímos para a literatura teórica e empírica sobre a relação entre distribuição de renda e demanda agregada. Baseando essa análise no arcabouço neo-kaleckiano, contribuímos para a literatura teórica através da construção de um modelo de economia aberta de dois setores que incorpora o efeito da desigualdade salarial sobre o padrão de consumo das famílias. Os resultados revelam as condições para a emergência de um processo circular de causação cumulativa entre a queda da desigualdade salarial e a transferência de empregos para o setor não comercializável, intensivo em mão-de-obra menos qualificada. O capítulo empírico dessa dissertação testa econometricamente a existência desse mecanismo cumulativo no Brasil, separando-o em dois exercícios: um Vetor de Correção de Erros (VEC) para a relação de longo prazo entre composição do produto e índice de Gini entre 1980 a 2014 e um Vetor Autorregressivo (VAR) para a relação de curto prazo entre as variações na desigualdade salarial e na composição do emprego no período entre 2004 e 2019. Os resultados parecem confirmar a hipótese de que as alterações na estrutura produtiva e na distribuição de renda reforçaram-se mutuamente ao longo do tempo / Central to the debate regarding increase in the income concentration between the 1960s and 1970s in Brazil, the role of the productive structure in the determination of wage distribution has been relegated to second place in the economic literature of the last decades. By rescuing these elements to analyze the relationship between the reduction of wage inequality and changes in the composition of employment in Brazil in the recent period, we contribute to the theoretical and empirical literature on the relationship between income distribution and aggregate demand. Basing this analysis on the neo-Kaleckian framework, we contribute to the theoretical literature by constructing an open economy model of two sectors that incorporates the effect of wage inequality on the household consumption pattern. The results reveal the conditions for the emergence of a circular process of cumulative causation between the fall of the wage inequality and the transfer of jobs to the non-tradable sector, intensive in less qualified labor. The empirical chapter of this dissertation econometrically tests the existence of this cumulative mechanism in Brazil, separating it into two exercises: an Error Correction Vector (VEC) for the long-term relationship between product composition and Gini index between 1980 and 2014 and an Autoregressive Vector (VAR) for the short-run relationship between changes in wage inequality and employment composition in the period between 2004 and 2019. The results seem to confirm the hypothesis that changes in the productive structure and income distribution were reinforced over time

En France, en 2010, un dixième de la population active était immigrée. Quel impact cet apport d’actifs a-t-il eu sur les salaires et l’emploi des natifs ? Une analyse centrée sur la substitution entre natifs et immigrés montre d’abord que l’immigration n’a eu qu’un faible impact sur le salaire des natifs de même niveau d’éducation et d’expérience. Une hausse de 10% de la part d’immigrés réduit le salaire mensuel des natifs de même qualification d’environ 0,6%. Ce résultat n’est pas surprenant compte tenu de la forte rigidité salariale qui caractérise le marché du travail français : l’existence d’un salaire minimum national et d’indemnités chômage élevées peut expliquer l’absence d’ajustement des salaires suite à une augmentation de l’offre de travail. Dans ce contexte de fortes rigidités salariales, l’ajustement porte sur le taux d’emploi. Nos résultats indiquent qu’une hausse de 10 % de la part des immigrés dégrade d’environ 3 % le taux d’emploi des natifs ayant des caractéristiques individuelles similaires : âge, formation, expérience professionnelle. L’emploi des natifs diminue au profit de celui des immigrés puisque ces derniers sont relativement plus attractifs pour les entreprises. Les immigrants sont notamment plus enclins à accepter des salaires plus faibles et des conditions de travail plus difficiles que des natifs de même qualification. Cette première analyse de court terme n’est que partielle puisqu’elle omet les effets de complémentarité que l’immigration devrait induire sur les travailleurs dont les qualifications différent de celles des immigrants. En tenant compte de ces effets de complémentarité, une seconde analyse montre que si l’immigration n’a aucune incidence sur le salaire moyen des natifs à long terme, l’immigration a produit en France des gagnants et des perdants depuis les années 1990. Dans la mesure où la population immigrée est de plus en plus qualifiée, l’immigration a réduit le salaire des natifs très qualifiés et augmenté celui des natifs faiblement qualifiés. L’immigration a donc contribué à la réduction des inégalités salariales entre les travailleurs qualifiés et non qualifiés constatée en France durant cette période. De même, nous montrons que la forte féminisation de la population immigrée a eu un impact différencié sur les salaires des natifs selon leur genre. Depuis 1990, nos estimations indiquent que l’immigration a diminué le salaire des femmes et augmenté celui des hommes. Cet effet asymétrique s’explique par le fait que les hommes et les femmes tendent à être imparfaitement substituables dans le processus productif. / In the past two decades, the fraction of the population in developed countries that is foreign-born increased from 7% in 1990 to 10% in 2010. The rise in the demographic importance of international migration led to a parallel increase in the amount of time and effort that economists devote to studying the consequences of immigration. One of the main questions raised by economists is related to the labor impact of migration in receiving economies. What is the impact of immigration on the employment and earnings of native workers ? This dissertation contributes to the immigration literature through a deep empirical investigation on the effects of immigrants on native wages and employment in France over the 1990-2010 period. This dissertation is composed of two main parts. The first part investigates the short-run effects of immigration on the outcomes of competing native workers (who have skills similar to those of the migrants). I find that immigration has a very small negative impact on the wages of competing natives. This result is consistent with the prevalence of downward wage rigidities in France. However, I show that immigration decreases the employment rate of natives with similar education and experience : a 10% increase in the immigrant share due to an influx of immigrants is associated with a 3% fall in the employment rate of competing natives. Since immigrants are relatively more attractive for firms (while they are identical to natives in all other respects), a substitution mechanism operates between natives and immigrants. The second part extends the analysis by providing a full picture of the wage impact of immigration in France. In this part, I allow the labor market to adjust to immigration in the long-run. In addition, I account for the complementarity effects induced by immigration on the wages of natives with different skills. The estimates indicate no detrimental impact of immigration on the average wage of natives. This part also provides the distributional effects of immigration by education and gender. In as much immigrants to France has been disproportionately high educated in the past two decades, I find that immigration has reduced the wage of highly educated native workers and has contributed to raise the wage of low educated. Thus, immigration-induced shocks to French labor supply have served to reduce wage inequality between low educated and high educated workers. Moreover, I find that immigration has lowered the relative wage of female natives and increased the wage of male natives. This asymmetric effect is due to the facts that immigration has disproportionately increased the number of female workers since 1990, and also that men and women of similar education are imperfect substitutes in the production process.

Among better-educated employed workers, the fraction of full-time full-year (FTFY) workers is quite high and stable over time in the U.S. Among those with low education levels, however, this fraction is much lower and considerably more volatile. These observations suggest that the composition of unobserved skills is subject to sharp movements within low-educated employed workers, while the scale of these movements is potentially much smaller within high-educated ones. The standard college premium framework accounts for the observed shifts between education categories, but it cannot account for unobserved compositional changes within education categories. This thesis uses Heckman&#039 / s two-step estimator on repeated Current Population Survey cross sections to calculate a relative supply series that corrects for unobserved compositional shifts due to selection in and out of the FTFY status. We find that the well-documented deceleration in the growth rate of relative supply of college-equivalent workers after mid-1980s becomes even more pronounced once we correct for selectivity. This casts further doubt on the relevance of the plain skill-biased technical change hypothesis. We conclude that what happens to the within-group skill composition for low-educated groups is critical for fully understanding the trends in the relative supply of college workers in the United States.

Nesse contexto, muito se tem discutido sobre a educação técnica e profissional, seus modelos de implantação e quais impactos esperar de políticas de fomento a essa qualificação. Esse trabalho representa um esforço para sistematizar os efeitos de políticas para o Ensino profissional e tecnológico(EPT). Assim, o presente trabalho tem como objetivo construir um modelo de sinalização no mercado de trabalho para verificar os efeitos de políticas públicas que afetem o acesso a cursos de EPT. Mais especificamente, o modelo aqui desenvolvido parte da análise de parâmetros normalmente utilizados por políticas públicas, como concessão de bolsas de estudo, ampliação da oferta de vagas na rede pública e diminuição do custo de obtenção de crédito estudantil, busca-se como essas ações impactam nos ganhos salariais advindos da conclusão do EPT em comparação com quem cursou ensino superior e ensino médio. O principal resultado do modelo teórico diz respeito ao fato de que algumas políticas públicas que buscam ampliar o acesso ao ensino profissional, podem ter efeito reverso, aumentando a desigualdade salarial de quem cursa ensino técnico em relação a quem cursa ensino superior. Isso pode ser explicado devido ao enfraquecimento do ensino profissional como sinal do produtividade do trabalhador. Com o objetivo de verificar se isso ocorre empiricamente foi realizada uma estimação de uma equação de salários utilizando a metodologia de diferenças-em-diferenças com pareamento, a partir de dados da Pesquisa Mensal do Emprego (PME/IBGE). Encontram-se indícios que os resultados do modelo teóricos ocorrem no Brasil, principalmente no setor de serviços. / Concern about the qualifications of labor and training of specific skills has been routinely debated, especially by developing countries. In this context, much has been discussed about the technical and vocational education, their deployment models and which impacts expected policies and support to this skillset. This work represents an effort to systematize the effects of policies for professional and technological education (EPT). Thus, this work aims to build a signaling model in the labor market to check the effects of public policies that affect access to EPT courses.More specifically, the model here developed begin from the analysis of parameters typically used by public policies, such as the granting of scholarships, extending the offer of vacancies in the public network and lowering the cost of obtaining student loans,to seek as these actions have an impact on wage gains arising from the conclusion of the EPT in comparison with those who attended higher education and secondary education. The main result of the theoretical model is the fact that some public policies that seek to expand access to vocational education, can have the reverse effect, increasing wage inequality between vocational and college education. This is due to the weakening of vocational education as worker productivity signal. With the objective to verify if this occurs empirically was performed a pet of an equation of salary using the methodology of differences in differences with matching from data from the Monthly Employment Survey (PME / IBGE). It is evidence that the results of the theoretical model occur in Brazil, mainly in the service sector.

We used four observable characteristics: edcuation, experience, the economic activity that the individual works and the region where he lives. The e ects of these characteristics are estimated by RIF regressions. The advantage of this method is that we can divide distributional changes into a wage structure e ect and a composition e ect and further divide the two components into contribution of each explanatory variable. We nd that the wage inequality in Brazil declines signi cantly from the late 1990 and this is explained mainly by a change in the returns of education. / Esse trabalho analisa o que aconteceu com a desigualdade salarial no Brasil nos anos de 1981 a 2009. Procuramos descobrir o papel que as características observáveis e os retornos a essas desempenha nas alterações da distribuição salarial. Usamos quatro variáveis explicativas: educação, experiência, atividade econômica do trabalho e região geográ ca em que mora. A partir de RIF - regressions descobrimos o papel de cada uma dessas covariadas individualmente. Nossos resultados mostram que houve uma signi cativa queda da desigualdade salarial no Brasil a partir do nal da década de 1990, explicada principalmente por mudanças nos retornos das características.

Les inégalités de revenus et la polarisation de l'emploi ont augmenté dans plusieurs pays au cours des dernières décennies, suscitant des préoccupations d'équité ainsi que des interrogations concernant les politiques de redistribution. Cette thèse répond à deux questions primordiales. La première concerne le rôle des heures travaillées et de leur dispersion pour expliquer les inégalités de revenu; la seconde porte sur le rôle de l'offre de travail des femmes dans l'explication de la polarisation de l'emploi. Le premier chapitre utilise des données pour les États-Unis, le Royaume-Uni, l'Allemagne et la France et examine comment les inégalités de revenu sont affectées par la dispersion des heures de travail. Le principal enseignement de cette approche est que la dispersion des heures de travail peut expliquer plus d'un tiers des inégalités de revenu dans certains pays et que la corrélation entre le salaire horaire et les heures travaillées s'est accrue au fil du temps. Le second chapitre s'appuie sur les résultats du précédent et explore les mécanismes qui expliquent la tendance à la hausse de la corrélation entre salaires et heures travaillées. Nous constatons qu'une plus grande volatilité de la production agrégée et une réglementation plus stricte du marché du travail ont tendance à réduire l'élasticité, alors qu'une augmentation du commerce dans un secteur les augmente. Enfin, le troisième chapitre met l'accent sur le rôle des femmes hautement qualifiées dans l'évolution du marché des substituts de la production domestique et montre que, lorsque les femmes hautement qualifiées travaillent plus d'heures, les femmes moins qualifiées sont plus susceptibles d'être employées. / Earnings inequality and job polarization have increased in a number of countries during the last decades, raising concerns of fairness and fostering debates on the implications for redistributive policies. This thesis asks two main questions. The first concerns the relevance of hours worked and their dispersion for earnings inequality, while the second question investigates the role of female labour supply in explaining the increase in job polarization. The first chapter uses data for the USA, the UK, Germany, and France and examines how earnings inequality is affected by the dispersion of working hours. The main result of this exercise is that hours dispersion can account for over a third of earnings inequality in some countries and that the relevance of the correlation between wages and working hours has been growing over time. The second chapter builds on the results of the previous one and explores the forces behind the upward trend of the correlation between wages and working hours. We find that greater aggregate output volatility and stricter labour market regulation tend to reduce the elasticity, while a greater trade share in an industry raises it. Finally, the third chapter investigates the relevance of female employment for job polarization in Germany. The analysis focuses on the role of high-skilled females in the evolution of a market for home production substitutes and finds that when top-employed females work more hours, low-skilled women are more likely to be employed.

Wage inequality is a well-established phenomenon of contemporary labour markets both in the United States and Europe, frequently discussed in the contemporary labour economics literature. In the following paper, based on harmonised data of the EU-SILC database, a semi parametric technique of quantile regression has been applied together with the traditional OLS method in order to estimate the impact of returns to education on wages in the Visegrad Group countries, namely the Czech Republic, Poland, Hungary and Slovakia. The main aim of the analysis is to examine the returns to education in these countries in order to observe differences appearing across them as well as within selected groups formed according to both the highest level of education attained and a number of years spent in a paid work (experience).

First chapter aims to quantify the role of trade in capital goods in cross country income differences. I construct a multi-country general equilibrium model of trade along the line of Eaton and Kortum (2002) and Alvarez and Lucas (2007) and introduce trade in capital goods and capital accumulation. In this framework, comparative advantage and the costs of international trade determine the pattern of production, specialization, and trade. I calibrate the model for 53 countries by estimating trade barriers and calibrating productivity parameters to match the bilateral trade data in 1996. The model is used to analyze full trade liberalizations. I find that removing barriers on investment goods accounts a large portion of reducing cross-country income differences and welfare gain. Counterfactual exercises suggest that developing countries gain relatively more than developed countries. In the second chapter, I focus on the impact of free trade on exportimport ratios in two different sectors. I employ a multi-country general equilibrium model of bilateral trade patterns along the line of Eaton and Kortum (2002) and Alvarez and Lucas (2007). I calibrate the model for 20 countries by estimating trade barriers and calibrating productivity parameters to match the bilateral trade data in 1996. The model is used to analyze full trade liberalizations. The impacts of free trade are predicted to be an increase in the export-import ratios in the comparative advantage sector and a decline in the comparative disadvantage sector, on average. In developing countries the average percentage change in export-import ratios exceeds the average percentage change in export-import ratios in developed countries. Finally, in the third chapter, I focus on the intergenerational human capital transmission. I develop and calibrate a theoretical model that considers three mechanisms of intergenerational transmission of human capital: (i) persistence in learning ability; (ii) parental investment in child’s human capital; (iii) higher teaching productivity of parents with more human capital. Within this framework, I find that (i) and (ii) plays important roles while (iii) does not. In addition the model generates the documented fact that higherwage parents spending more time teaching their children in spite of the higher opportunity cost. I asses the role of nature and nurture effects in intergenerational persistence of earnings and I find that nature accounts a large portion of the intergenerational persistence in earnings. I also quantify the relative importance of these mechanisms on wage inequality. / text
