A refinement of Hoeffding's inequality

In this paper, we present a refinement of Hoeffding's inequality which is of closed form and which significantly improves on this inequality in many cases. Some numerical comparisons are also presented.     

Tests for exponentiality against NBUE alternatives: a Monte Carlo comparison

Testing of various classes of life distributions has been addressed in the literature for more than 45 years. In this paper, we consider the problem of testing exponentiality (which essentially implies no ageing) against positive ageing which is captured by the fairly large class of new better than used in expectation (NBUE) distributions. These tests of exponentiality against NBUE alternatives are discussed and compared. The empirical size of the tests is obtained by simulations. Power comparisons for different popular alternatives are done using Monte Carlo simulations. These comparisons are made for both small and large sample sizes. The paper concludes with a discussion in which suggestions are made regarding the choices of the test when a particular alternative is suspected.     

The Relative Deprivation Curve and Its Applications

This article introduces the relative deprivation curve to represent the size distribution of income and wealth. The curve has many useful applications in the measurement of poverty and inequality, which are explored. The methodology developed is then applied to the data obtained from the Australian Household Expenditure Survey, 1975–1976.     

Relative Price Changes and Inequality in the Size Distribution of Various Components of Income

This article uses a comprehensive model of economic inequality to examine the impact of relative price changes on inequality in the marginal distributions of various income components in which the marginal distributions are derived from a multidimensional joint distribution. The multidimensional joint distribution function is assumed to be a member of the Pearson Type VI family; that is, it is assumed to be a beta distribution of the second kind. The multidimensional joint distribution is so called because it is a joint distribution of components of income and expenditures on various commodity groups. Gini measures of inequality are devised from the marginal distributions of the various income components. The inequality measures are shown to depend on the parameters of the multidimensional joint distribution. It is then shown that the parameters of the multidimensional joint distribution depend on the relative prices of various commodity groups and several other specified exogenous variables. Thus, knowledge of how changes in relative prices affect the parameters of the multidimensional joint distribution is deductively equivalent to knowledge of how changes in relative prices affect inequality in the marginal distributions of various components of income. It is found that relative price changes have a statistically significant impact on inequality in various components of income.     

Cognitive and non-cognitive traits and the intergenerational transmission of socioeconomic inequality

This paper studies the roles of cognitive and non-cognitive characteristics in a standard Roemerian Inequality of Opportunity (IOP) model. Using Australian microdata, we model the effects of individuals’ backgrounds and their psychological traits on two adult income variables. We find that measurable psychological traits (intelligence, locus of control, big five personality traits) are slightly more important than background characteristics (such as race, gender, social class at birth) in explaining income disparities. However, the fraction of IOP confounded by psychological factors is small (11%–12%), which suggests that background inequalities do not meaningfully reflect differences in cognitive or non-cognitive ability.     

Black lives matter,capital, and ideology: Spiraling out from India

Piketty's propositions for arresting inequality are discussed through the lens of racism/casteism. We focus on the case of India's George Floyds—the persistence of caste and tribe oppression under economic growth in India—through the insights of our long‐term ethnographic research. We show that inequalities are intimately tied to dynamics of capitalist accumulation in which racial/ethnic/caste/tribe and gender difference is crucial. We argue for an analysis that truly integrates ideology and the dynamics of political economy. The wider implications, we argue are political; they lie in the question of what is to be done. Despite his ambitions to decenter economics, Piketty remains trapped in the logic of economics for what he proposes are essentially economic reforms within capitalism. Moreover, ideological change cannot be a matter of choice only, and cannot be challenged solely at the level of ideas around economic inequality. It will also have to be fought as a direct contest of oppressive ideologies such as racism, casteism, and patriarchy, leading to new counter‐hegemonic positions. We will argue that this takes us from a global history of ideology to a global anthropology of praxis. A first step is to genuinely center conversations with disciplines like anthropology, sociology, and subaltern history studying people and voices from below and from the margins, and the perspectives of scholars and activists from below and from the margins.     

Young people looking forward: Imagined future and normative tensions in urban Norway

We explore the meaning-making practices of ‘little personal stories’ and ‘big societal stories’ in the imagined futures of 12- and 13-year-olds within Norway, known for its egalitarian ideals and welfare society. Using the concept ‘prospective narratives’, we explore these practices through the students' narrative world-making. The narratives connect the imagined future with gender and class variations related to larger social norms in the arenas of work and family. They demonstrate embodied and positioned cultural knowledge of the present, reflecting tensions between dominant social norms—‘big stories’—in terms of child-centred parenting, active work-life and egalitarian ideals across gender and class.     

Is America coming apart? Socioeconomic segregation in neighborhoods,schools, workplaces,and social networks, 1970–2020

As income inequality in the United States has reached an all-time high, commentators from across the political spectrum warn about the social implications of these economic changes. America, they fear, is “coming apart” as the gap between the rich and poor grows into a fault line. This paper provides a comprehensive review of empirical scholarship in sociology, education, demography, and economics in order to address the question: How have five decades of growing economic inequality shaped America's social landscape? We find that growing levels of income inequality have been accompanied by increasing socioeconomic segregation across (1) friendship networks and romantic partners, (2) residential neighborhoods, (3) K-12 and university education, and (4) workplaces and the labor market. The trends documented in this review give substance to commentators' concerns: compared to the 1970s, rich and poor Americans today are less likely to know one another and to share the same social spaces. The United States is a nation divided.     

“重返阶级”:理论与意义

“重返阶级”是作为对“阶级消亡”的回应和反击而出场的。“重返阶级”论主张，社会阶级结构和阶级关系的确在历史中变化，但阶级和阶级关系的本质没有改变，阶级继续存在并持续地影响着社会，阶级分析仍然是分析社会的有效工具。“重返阶级”的努力得益于将工作场所作为权力体系和阶级对抗场所的当代劳工研究，这种从“工场权力”的角度来划分阶级的研究正确地揭示了社会阶级不平等的现象。阶级话语的再出场是社会不平等的理论回声，新时代阶级存在表现出工人阶级“新贫困”、中产阶级“再无产阶级化”和全球工业阶级形成等新特点和新趋势，应当重返阶级，把工人带回分析的中心，以新视角坚持和重塑阶级话语。     

Gender inequality in mobile technology access: the role of economic and social development*

ABSTRACT

Digital inequality is a burgeoning field of study across disciplines, yet few papers address categorical digital inequality in cross-national samples. Using the only available cross-national data on access to Information and Communications Technologies (ICTs) disaggregated by gender from the International Telecommunications Union (ITU), I add to existing literature by examining factors associated with women’s unequal access to mobile phones across 51 countries. The largest of such samples, the ITU data demonstrates that the type and levels of gender inequality in mobile phone use are not consistent throughout countries. In fact, the distribution is quite variable, from incorporating a small-sample of nations where women have marginally higher access, to sub-samples close to parity, to a larger sub-sample where women are at a substantial disadvantage. Using Quantile Regression Methods to assess these variations, I test how major gender and international development theories inform inequality patterns. My findings suggest that women’s wellbeing, as measured by their access to modern contraception (i.e., reproductive autonomy), overwhelmingly promotes women’s relative access to mobile phones, regardless of preexisting levels of access. Other perspectives like the growth imperative and world polity theory show some staggered associations along the distribution that remain substantively inconclusive.
