Judgment of distributional inequality in networks

Why is income inequality perceived and judged differently across a society? Following the social comparison theory, one reasonable explanation suggests that individuals are exposed to different local reference groups in social networks. We design a vignette experiment to study how income distributions are judged by individuals structured in networks. The experiment shows that perceptions of distributional inequality are high when network ties are unequally distributed across individuals, suggesting that network inequality contributes to distributional inequality. Beyond the network effect, inequality judgment is found to be driven by a mix of self-interest and other-regarding preference: people are in favor of group-beneficial income distributions wherein they rank high, but not extremely high, in the group. It shows that people care about not only their relative affluence, but also where others stand in the distribution.     

Distributive effects of benefits and taxes

In light of the growing federal deficit, pressure is mounting to cut federal spending. If the budget for social security programs is cut, who will suffer? This article presents the results of a study that investigated the degree to which taxes and public income transfers change the level of income, the degree of inequality in income distribution, and the poverty rates of various demographic groups. Major findings are that public income transfers are more powerful than taxes in equalizing the income distribution and that poverty reduction through non-means-tested transfer programs is more effective among elderly people, white people, and people in married-couple families, whereas poverty reduction through means-tested transfer programs is more effective among nonelderly people, black people, and people in female-headed families. Implications for social work practice are discussed.     

Income Inequality and Chronic Health Conditions: A Multilevel Analysis of the U.S. States

Recently, scholarly work has examined the effect of rising income inequality on health outcomes. However, this work is somewhat inconclusive. The mechanisms that could produce such an association are still being sorted out. Much of this work focuses on mortality outcomes with little attention to how this process operates for actual health conditions, including chronic health problems—arguably the main public health concerns of the developed world. In a series of multilevel binary logistic regression models using data from the 2005 and 2007 Behavioral Risk Factor Surveillance System, we examine the association between state-level income inequality, poverty, and social welfare measures on spending and policy to examine the association between these factors for three chronic health outcomes: diabetes, hypertension, and coronary heart disease. We find that income inequality is conditionally positively related only to the diagnosis of diabetes and hypertension, and only in 2007. However, absolute poverty is related to the outcome across all three dependent variables. Certain social welfare measures attenuate the effects of both income inequality and absolute poverty, suggesting that some policies reduce this association.     

Does income inequality harm health? New cross-national evidence

The provocative hypothesis that income inequality harms population health has sparked a large body of research, some of which has reported strong associations between income inequality and population health. Cross-national evidence is frequently cited in support of this important hypothesis, but the hypothesis remains controversial, and the cross-national work has been criticized for several methodological shortcomings. This study replicates previous work using a larger sample (692 observations from 115 countries over the 1947-1996 period), a wider range of statistical controls, and fixed-effects models that address heterogeneity bias. The relationship between health and inequality shrinks when controls are included. In fixed-effects models that capture unmeasured heterogeneity, the association between income inequality and health disappears. The null findings hold for two measures of income inequality: the Gini coefficient and the share of income received by the poorest quintile of the population. Analysis of a sample of wealthy countries also fails to support the hypothesis.     

Does income inequality contribute to credit cycles?

Recent literature presented arguments linking income inequality to the financial crash of 2007–2008. One proposed channel is expected to work through bank credit. I analyze the relationship between income inequality and bank credit in a panel cointegration framework and find that they have a long-run dependency relationship. Results show that income inequality contributed to the increase of bank credit in developed economies after the Second World War.     

Inequality decomposition values: the trade-off between marginality and efficiency

This paper presents a general procedure for decomposing income inequality measures by income sources. The methods of decomposition proposed are based on the Shapley value and extensions of the Shapley value of transferable utility cooperative games. In particular, we find that Owen’s value can find an interesting application in this context.We show that the axiomatization by the potential of Hart and Mas-Colell remains valid in the presence of the domain restriction of inequality indices. We also examine the properties of these decomposition rules and perform a comparison with Shorrocks’ decomposition rule properties.     

Trend Analysis of Anticipated Lifetime Income Inequality among Post‐war Japanese Youth

This study aims to measure the inequality of anticipated lifetime income and the inequality of annual income among the younger generation (24–29‐year‐old men), and to examine any trends that can be found in terms of inequality between 1955 and 2005 in Japan. Anticipated lifetime income is defined in this study as the present value of the total anticipated annual income that one is likely to earn each year between the ages of 24 and 59 years, assuming that there is no intragenerational class mobility. The anticipated lifetime income for each young male is estimated using the Social Stratification and Social Mobility Survey dataset, which is a Japanese national cross‐sectional survey of social stratification and social mobility. An inequality in the anticipated lifetime income can be regarded as an “inequality of outlook” among the younger generation. As a result of this analysis, it was found that the Gini coefficient, the most general measurement of income inequality, had significantly increased for anticipated lifetime income between 1995 and 2005. At the same time, the gap between the Gini coefficient of anticipated lifetime income and that of annual income had narrowed. It is suggested that “inequality of outlook,” which cannot be easily identified using a superficial index, has increased significantly.     

An Ex-Post View of Inequality of Opportunity in France and its Regions

This paper proposes an ex-post measure of inequality of opportunity in France and its regions by assessing the inequality between individuals exerting the same effort. To this end, we define a fair income that fulfils ex-post equality of opportunity requirements. Unfairness is measured by an unfair Gini based on the distance between the actual income and the fair income. Our findings reveal that the measures of ex-post inequality of opportunity largely vary across regions, and that this is due to differences in reward schemes and in the impact of the non responsibility factors of income. We find that most regions have actual incomes closer to fair incomes than to average income, excepted Ile de France where the actual income looks poorly related to effort variables. Finally, we find that income inequality and inequality of opportunity are positively correlated among regions.     

"A 20% income increase for everyone?": The effect of relative increases in income on perceived income inequality

Most research on income inequality implicitly assumes that a fixed percentage increase in income across all income levels does not alter income inequality. In contrast with this assumption, we show that relative increases in income lead to increased perceptions of inequality, even when buying power is held constant. In a second experiment, we extended these findings using a fictitious currency, thereby eliminating effects of using a familiar currency. In study 3, we demonstrate that feelings of envy and fairness are affected by a fixed percentage income increase.     

Difficulties in Shifting from Individualistic to Socio-political Policy Regarding Disability in Canada

An individualistic conception of disability has been replaced by a socio-political definition. The socio-political model implies that disability stems from the failure of the social environment to adjust to the needs of people with disabilities rather than from the inability of disabled individuals to adapt to societal demands. This paper will examine the extent to which Canadian policies have changed to embrace this new definition. There has been some progress in policies related to shelter, transportation and recreation. However, policies related to income and employment are still individualistic in nature because policy change in these areas requires a major shift in governmental approach to unemployment and fundamental reform of the Social Assistance system. In a period of high unemployment, people with disabilities are viewed as surplus labour, and the Canadian government has found that high unemployment is politically tolerable. Obstacles to an increase in income support include a strong work ethic, the philosophy that social assistance benefits should be less than could be earned in the work-force, and the private insurance and litigation industries which benefit from the current income system. Other barriers to change are the lack of power of disabled groups and the dominance of professionals.     

Common and Specific Learnings for a Graduate of a School of Social Work

Abstract

Developing new scholarship on women is a recognized need in social work education. It can be furthered by applying a “gender lens” to the knowledge of the relationship between women and the welfare state. Reflecting historical concerns about providing public aid to the able-bodied male pauper and the impact of relief on the work ethic, social welfare literature has focused on male recipients while generalizing its findings to women. As a result, the story of the female pauper remains largely untold. This paper suggests that the relationship between women and the welfare state is shaped by a “family ethic” that in many ways parallels the work ethic known to shape the relationship between the welfare state and men. The family ethic is defined and applied to major income maintenance programs: public aid and social security. This article suggests foci for change.     

Young people's views of children's rights and advocacy services: a case for ‘caring’ advocacy?

This paper looks at some preliminary findings from research with young people in foster and residential care in the UK who have received advocacy services from a range of local authority and voluntary agencies. The study also includes the views of professionals, from both children's rights and social services. The initial findings highlight the importance to young people of their relationship with rights professionals. They speak about the value to them of care and respect, aspects not always seen as fundamental to rights work. Caring, in its various guises is seen by young people as a vital component of their relationship with children's rights workers. They also see this as important within advocacy work itself since caring about the outcome is often key. A pure individual rights focus with an emphasis on challenge and ‘being heard’ may not take account of the complexity of their situation and may pose difficult dilemmas for young people, especially in dealings with their carers. This ‘caring’ advocacy is not the paternalistic approach of a professional who ‘knows what's best for you’ but is a model based on a strong awareness of ways that young people are excluded and oppressed. It is also about placing a positive value on their contribution as citizens and links to a view of society that gives importance to an ethic of inter‐relationship and care as well as an ethic of individual rights.

A general class of inequality elasticities of poverty

Many authors have recently emphasized the crucial role of income inequalities in the design of efficient policies aimed at reducing poverty. However, the link between variations in the degree of inequality and variations in poverty is not well documented. The literature, for instance, does not provide any satisfying tool for predicting how a small relative variation in the Gini index may be associated with a variation in the headcount index. In the present paper, we define a family of Lorenz curve transformations that can directly be interpreted in terms of relative variations of known inequality measures. Then, we extend Kakwani’s (Rev Income Wealth 39(2):121–139, 1993) methodology for the calculation of inequality elasticities of poverty. Improvements are threefold with respect to Kakwani’s work. First, our formulas are not confined to the sole Gini index. Secondly, they embrace the uncertainty and the complexity of the mechanical link between inequality and poverty. Third, using some flexible functional form, one can easily perform an accurate estimation of the point inequality elasticities of poverty corresponding to observed variations of a given income distribution. We also propose a simple measure that may be helpful to assess how “pro-poor” are inequality variations by comparing the observed elasticities with the set of theoretical elasticities that could be obtained from the initial income distribution.     

Work hours and wage inequality: Evidence from the 2004 WERS

This paper uses the 2004 wave of the Workplace Employment Relations Survey to test whether work hours and wage inequality are positively correlated because of financial incentives associated with inequality. Workers may work longer hours in order to increase their expected income through performance pay or promotion, resulting in a positive correlation between inequality and work hours. Contrary to other work, it is found that the relationship between wage inequality and the occupation and firm level and work hours cannot be attributed to the effect of financial incentives. Demand constraints faced by workers explains the positive correlation between occupation inequality and work hours attributed to financial incentives by others.     

Inequality and education decisions in developing countries

In this paper we analyze the effect of inequality on school enrollment, preferred tax rate and expenditure per student in developing countries; when parents can choose between child labor, public schooling or private schooling. We present a model in which parents make schooling decisions for their children, weighing the utility benefit of having a child with formal public or private education versus the forgone income from child labor or household work. Parents vote over the preferred tax rate to finance freely provided public education. The utility benefit of an educated child is proportional to expenditure per student, so that there is congestion in public school. We find that when parents can send their children to work or to private school, high inequality leads to exit from public education at both ends of the income distribution. Thus high inequality reduces the support for public education, leading to a low tax rate and expenditure per student. Exit from public education results in both high child labor and a large fraction of students attending private school. In fact there is a threshold level of inequality above which there is no longer support for public education. In addition we explore the implications for the design of foreign aid. The results suggest that foreign aid policies should focus on promoting school attendance rather than increasing school resources, as the later policy might be offset by a reduction in the recipient country’s fiscal effort, with little impact on outcomes.      

Income inequality,poverty and crime across nations

We examine the relationship between income inequality, poverty, and different types of crime. Our results are consistent with recent research in showing that inequality is unrelated to homicide rates when poverty is controlled. In our multi‐level analyses of the International Crime Victimization Survey we find that inequality is unrelated to assault, robbery, burglary, and theft when poverty is controlled. We argue that there are also theoretical reasons to doubt that the level of income inequality of a country affects the likelihood of criminal behaviour.     

Growth with equity: income inequality in Vietnam, 2002–14

We use the 2002 through 2014 Vietnam Household Living Standards Surveys to construct comparable measures of household income and estimates of income inequality over this high-growth period. We focus on two questions: How have benefits from growth been distributed; and do changes in the structure of the economy map into changes in inequality? We explore dimensions in which inequality may vary, notably urban versus rural, and by ethnic status. We also decompose inequality by income source to highlight key factors underlying the relatively low levels of inequality during this period. We find that agricultural opportunities played an important role in dampening inequality, but more important has been the steady development of wage-labor markets in both urban and rural areas. An important caveat to the generally rosy picture we paint is the deteriorating position of ethnic minorities. Finally, we draw comparisons with China and document key differences in their growth-inequality experiences.     

FDI AND INCOME INEQUALITY: EVIDENCE FROM A PANEL OF U.S. STATES

This study employs state‐level panel data to explore the relationship between inward foreign direct investment (FDI) and income inequality in the United States. Using panel cointegration techniques that allow for cross‐sectional heterogeneity and cross‐sectional dependence, we find that, in the long run, FDI exerts a significant and robust negative effect on income inequality in the United States. This result for the United States as a whole does not imply that FDI narrows income gaps in each individual state. There is considerable heterogeneity in the long‐run effects of FDI on income inequality across states, with some states (21 out of 48 cases) exhibiting a positive relationship between FDI in income inequality.(JEL F21, D31, C23)     

Middle Class Identity in the Modern World: How Politics and Economics Matter

It is widely accepted that people tend to identify with the middle classes regardless of their social class position. Nevertheless, this “middle class identity bias” is not equally prominent in all western democracies. The goal of this article is to assess the role of political and economic conditions in shaping this phenomenon. By exploring the relationship between class identity and national context in 15 modern societies, I address two main questions: (1) how individual‐level income affects where people place themselves in the class system, and (2) how national political and economic context affects this relationship. In doing so, I offer several important findings. First, although there is a positive relationship between income and class identification in all 15 societies, middle class identification is weakest when income inequality is high. Consistent with previous findings, the results suggest that economic development has a positive impact on class identity. The results also uncover a role for political ideology by suggesting a lingering affect of Communist rule. Even after controlling for economic development and income inequality, respondents in former Communist countries are more likely than others to identify as belonging to a low social class.     

The globalization of production,national labour regulations and income inequality in the global North and South, 1980–2013

A central concern over global value chains (GVCs) is whether the integration of national firms into GVCs exacerbates income inequality within countries. However, despite decades of research, the distributional consequences of GVCs remain unclear in the empirical literature. Drawing on panel data from 96 countries between 1980 and 2013, we examine the effects of GVC integration on market income inequality and whether national labour regulations moderate these effects. We find integration increases inequality in the global North and South. More importantly, we find labour regulations amplify the inequality effects of integration in Southern countries by expanding the size of the informal sector while suppressing these effects in Northern countries by promoting unionization. This suggests institutional power from national labour regulations may enhance the bargaining power of labour in the North through increasing collective resources while disempowering labour in the South through reinforcing labour market segmentation between formal and informal sectors.
