In the current multifaceted context, there are actors who benefit from global structural design while others are being imposed barriers to access wealth - which, it is argued, if there was a global distributional architecture focused on fairness, could be better allocated so as to benefit a larger number of individuals. In this matter, mainly using bibliographical research, the paper has the objective to demonstrate that the Rawlsian view, although applicable to hermetic societies, is inadequate for a world submerged in economic inequalities highly tainted by the form of historical, predatory and usurpatory accumulation imposed by the more economically developed countries in relation to the global poor. Therefore, this paper seeks to demonstrate, by an overall analysis and with the scope of the global justice theory as explained by Thomas Pogge, the way in which the global structuring selectively harms, still today, – namely, specially through international resources and loans privileges –, countries, keeping them – or, more often, their populations – in poverty [ABSTRACT FROM AUTHOR]

Abstract The paper’s primary goal is to analyze the effects of politics and administrative capacity on countries’ innovative performance. The inquiry comparatively examines possible correlations between democracy, political competition, income inequality, bureaucratic capacity, and corruption/transparency with countries’ innovation results. The dependent variables are three performance indicators of the Global Innovation Indexes (GII). After presenting the theory and the descriptive data analysis on the research variables, the paper runs multivariate regression models to test the hypotheses. The empirical analysis reinforced that political and administrative dimensions are relevant to understanding the national innovation systems’ achievements. However, democracy, bureaucracy quality and corruption/transparency are not influential factors in countries’ innovative results as the normative assumptions would suppose. On the contrary, political competition and inequality considerably impact how economies innovate. In conclusion, the paper brought original and intriguing findings that put in perspective the claim that there is a unique path or rule of thumb for innovation growth. Consequently, the inferences provide insights to scholars and stakeholders, public and private, to improve the debates and decisions regarding the priorities for government actions in times of evidence-based policymaking.

This paper analyses the project of the private insurance sector to assume the role of protagonist in guaranteeing social protection and investigates its consequences for the management of inequalities. In Brazil, as in other countries, austerity policies have been implemented causing significant impacts on social insurance and benefits reduction. Based on multisite ethnographic research (2017-2019), developed with insurance market agents, this article analyses the processes of financialisation of social protection and popularisation of private insurance in contemporary Brazil.

COVID-19 has exposed, reproduced, and created new inequalities in Latin America and the world. In this introductory paper, we discuss the impact of extant inequities on vulnerability to COVID-19 but we also identify new, and some unexpected, vulnerabilities. We emphasize vulnerabilities to the disease as well as vulnerabilities to policies and other responses in the fight against COVID-19. Building on insights from Peter Hall and Michele Lamont’s work on social resilience, we draw on the papers of this special issue to identify the important role of the state in addressing vulnerabilities and discuss the types of social resilience that vulnerable groups have turned to in their response to COVID-19.

This paper used the Mankiw, Romer and Weil (1992) model, with crosssection and panel data and spatial controls, to analyze the influence of spatial phenomena on inequality and economic growth in Brazilian municipalities between 1980-2010. The results indicated that reducing spatial heterogeneity (e.g.: differences in culture, preferences and natural resources) helps to combat inequalities, while the absence of spatial spillovers (from trade, technological diffusion and migration, for instance) tends to worsen it. Ignoring these spatial effects would result in underestimations of the rate of income convergence and overestimates about the returns on physical capital and human capital. Finally, being close to a "central place", as in the case of state capitals, seems to facilitate the economic growth. [ABSTRACT FROM AUTHOR]

Purpose – The paper aims at assessing the evolution of the digital divide in Brazil in the last decade from a multidimensional perspective, going beyond the issue of access. How have the inequalities in the use of Internet in Brazil varied through time? Methodology – The paper investigates the relationship between individual socioeconomic characteristics and household characteristics, and the pattern of Internet access and use in Brazil using multivariate analysis, drawing on data from national ICT surveys between the years 2000 and 2019. Findings – The results show that increasing access do not necessarily result in a more equitable adoption and use of available online resources. They highlight a persistent “digital elite” capable of a more sophisticated use of the Internet. The maintenance — and even the increase — of differences in the use of Internet is in line with part of the literature on digital inclusion. Practical Implications – The study underscores the importance of developing methodological frameworks to better measure the digital divide, allowing it to be used as the independent variable in broader analyses of income inequality and access to public services, for instance. Additionally, the persistence of a "second level digital divide" in Brazil points to the need for policies that address the "digital skills gap" enabling the realization of the Internet's potential to ease social disparities. Originality – Despite the existing literature on the relationship between online inequalities and other kinds of inequalities, there are still few empirical studies, especially with a multidimensional perspective.

This paper analyzes the relationship between full-time journeys and schooling inequality in Pernambuco, Brazil. Using standardized test scores on the school level, we tested the inverted u-curve hypothesis proposed initially by Simon Kuznets in 1955 and adapted with a focus on schooling expansion and inequality by Rati Ram in 1990. We build a panel data analysis to perform the test, with data aggregated by region and scores on standardized tests as the output variable. Initially, the hypotheses described an inverted U-curve correlating schooling effectiveness and inequality. However, we have found that the relationship follows a regular U shape. It is also inferable that the equity of the result is more connected to the effects of the diversity of school typology, the location of schools, and the way the region is developed.

This paper examines the theoretical approaches to the persistence of class inequalities in educational attainment and social mobility. After examining them, the paper stresses their insufficiencies to explain the reproduction of class inequalities in education and social mobility, and also the possibility of social change.

This paper presents the results of a study on how students build memories in School's Physical Education classes. To this end, we seek to discuss how youth and gender inequalities in high school can affect teenage girls and influence them into excluding these classes. The investigation was carried out through semi-structured interviews with sixty 3rd year high school students, in six public schools and six private schools in Pernambuco. The study reveals that the students' experiences are marked by a process of gender inequality, which is strenghted by the absence of teacher's intervention. [ABSTRACT FROM AUTHOR]

This paper intends to understand how the mandatory wearing of white uniforms by babysitters in the south side of the city of Rio de Janeiro, Rio de Janeiro State, Brazil, is characterized by social segregation. The uniform as a social symbol "defines and determines" the position of invisibility and subordination occupied by these workers. Women who work as babysitters at Leblon, on the south side of the city of Rio de Janeiro, were interviewed for this study. Wearing the uniform is about the identification and safety of the worker. In the specific case of the babysitter, however, the uniform has a significant symbolism, which refers to submission, exclusion, and segregation. [ABSTRACT FROM AUTHOR]

Often, all too often, global working-class solidarity remains fragile, conditional or fails to be realized in practice, whatever the lofty rhetoric may be. The present paper explores one possible explanation: workers in the North profit from the exploitation of workers in the South through cheap commodities and services, and additional job opportunities. For example, wage-earners in the North can buy T-shirts so advantageously because their real wages are much higher than the real wages of labourers in the Global South. This is what I would like to call a relational inequality within the world working class: some workers are better off because other workers are worse off. The paper presents a very tentative historical outline of global relational inequality since the 1830s.

This paper aims to calculate and to analyze a rural development index for the municipalities of Pará state, Brazil. The index was calculated by the factor analysis method. The variables used in the model were retrieved from the 2000 and 2010 population census; Human Development Atlas - UNDP (2013), and census of agriculture (2006). The results unveiled that most of the municipalities of Para presented low rural development index values. The greater is the isolation and the difficulty to access the areas, the worse it is the infrastructure found in those rural areas. Colonization of new areas was not followed by the implementation of services and the required infrastructure to provide life quality for both native and the migratory population that installed in the rural areas of Para state, Brazil.

In a recent paper published in Novos Estudos Cebrap, Arminio Fraga maintains that the Brazilian State, in addition to being costly and inefficient, acts to deepen inequality. The economist proposes a set of reforms seeking its drastic reduction. Our article aims to refute this assessment, based on theoretical and empirical arguments and extensive literature, and to point out the risks to economic and social policies brought about by the suggested reform agenda.

Abstract What are the effects of extractive informal institutions on the horizontal accountability process in a developing democracy? This paper presents evidence about the harmful effects of extractive informal institutions on horizontal accountability within subnational governments in Brazil. After three decades of free and competitive elections, the institutional design of oversight institutions for state governments has hardly changed. We explore the hypothesis that more extractive informal institutions, measured by the level of income inequality, is associated with decreasing transparency levels. Given its extensive social, political, and economic diversity embedded in an overall centralized formal institutional framework, Brazil provides an appropriate setting to test the hypothesis that extractive informal institutions responsible for increased income inequality can undermine horizontal accountability in new democracies.

ABSTRACT This paper shows that income distribution can change dramatically during the business cycle. This finding contrasts with the widespread belief that income distribution changes slowly in the absence of wars and revolutions. Macroeconomics explains in good measure short-run variations in income distribution: inequality varies cyclically, and it increases with inflation and unemployment. Furthermore, at least in Brazil, the minimum wage legislation does not contribute to a better income distribution. There is also evidence that populist policies which lead to real appreciation cannot be justified as supporting the poor. Thus, the best way to help the poor is demonstrably not through the manipulation of prices and wages, but probably through macro stability and a transparent tax-transfer system.

Our paper draws on our ethnographic work regarding transnational adoption, unauthorized immigration, and deportation in order to examine the grids of intelligibility that produce adoptability and deportability. Adoptable babies, unauthorized migrants, and deportable aliens are, in some sense “off the grid” in that aspects of their pasts took place elsewhere, or are unknown or sealed, thus enabling them to be excluded or removed from particular polities. Such individuals appear to move – between statuses, territories, and states of being. At the same time, the very possibility of such movements, indeed, of alienability, unsettles the very grids of kinship, property, nationality, and belonging on which exclusions and removals are based. Adoption, migration, and deportation are therefore processes that disturb and fascinate, as evidenced by the numerous news articles about adoptees who return to discover their “roots,” or the hardships and successes of migrants. These stories are not only about the individuals involved but also the nations and assumptions about national “essences” that make it possible to “locate” persons. Our analysis seeks to interrogate these assumptions, while providing alternatives to the grids of deservingness and ideas about a child’s “best interest” that underpin immigration policy and adoption law. Este artículo muestra el trabajo etnográfico realizado sobre la adopción transnacional, la inmigración no autorizada, y la deportación, para examinar las redes de inteligibilidad que fomentan la adopción y deportación. Bebés adoptables, inmigrantes no autorizados, y extranjeros deportables están, en cierto sentido "fuera de juego", ya que su pasado se desarrolló en otros lugares, es desconocido o inaccesible, lo que favorece que sean excluidos o eliminados de políticas particulares. Parece que estas personas se mueven entre status, territorios y estados del ser. Al mismo tiempo, la posibilidad de tales movimientos, esto es, de extranjería, perturba las redes de parentesco, propiedad, nacionalidad y pertenencia en que se basan las exclusiones. Adopción, inmigración y deportación son por lo tanto, procesos que perturban y a la vez fascinan, como lo demuestran los numerosos artículos de prensa acerca de adoptados que vuelven a descubrir sus "raíces", o las dificultades y los éxitos de los inmigrantes. Estas historias no están relacionadas únicamente con las personas involucradas, sino también con las naciones y las asunciones sobre las "esencias" nacionales que permiten "localizar" personas. Este análisis busca cuestionar estos supuestos, al tiempo que proporciona alternativas a las redes de merecimiento e ideas sobre el "interés superior" del niño en que se basa la política de inmigración y la ley de adopción.

Land concentration, historically based on the Gini index, has always been a central element in the theoretical debate on the Brazilian agrarian question. This paper try to point out a series of imprecisions in the use of the Gini index to analyze the land concentration. From the reading of the bibliographic material selected and the calculation of the Gini index simulating several hypothetical situations for a municipality in the state of Minas Gerais, it was verified that the analysis of the land concentration made only from the calculation of this index can lead to mistakes in the considerations on the Brazilian land structure. Some complementary factors that should be considered in the analysis of land concentration are also presented. [ABSTRACT FROM AUTHOR]
