Does regional variation affect ecological mortality research? An examination of mortality, income inequality and health infrastructure in the Mississippi Delta

Mortality research has often focused on individual-level, socioeconomic, and demographic factors indicating health outcomes. Consistent with a recent trend in the public health field, this research examines mortality at the aggregate, contextual level. Based on Wilkinson’s relative income hypothesis, specifically being manifest through an underinvestment in social goods including health infrastructure, the focus of this study is a regional examination in the effects of income inequality on mortality at the county level. Health infrastructure is included as a mediating variable in the relationship between income inequality and mortality, relating back to Wilkinson’s work. Unlike previous research, regional differences in this relationship are examined to identify variation at the county level in health outcomes. The Mississippi Delta is an adequate test bed to examine the relationship between these variables based on its socioeconomic, demographic, and high inequality characteristics. It is hypothesized that Delta-designated counties within the three-state Delta region distinguish a significant positive relationship between income inequality and mortality, that this relationship is stronger than in non-Delta classified counties, and that health infrastructure significantly mediates the relationship between income inequality and mortality.     

Family and neighborhood sources of socioeconomic inequality in children’s achievement

We examined family and neighborhood sources of socioeconomic inequality in children’s reading and mathematics achievement using data from the 2000–2001 Los Angeles Family and Neighborhood Survey. To describe inequality in achievement scores, we used Gini coefficients and concentration indices and multilevel regression models. We found no inequality in children’s achievement by family income when other variables in the model were held constant. Mother’s reading scores and average neighborhood levels of income accounted for the largest proportion of inequality in children’s achievement. Neighborhood economic status appears to be strongly associated with children’s skills acquisition.     

Relative Standing and Subjective Well-Being in South Africa: The Role of Perceptions,Expectations and Income Mobility

Most studies that explore the impact of relative standing on subjective well-being use objective measures of the individual’s relative position, such as the mean income of the reference group or the individual’s ranking in the relevant income distribution. In this paper, using a new household survey from South Africa, we are able to derive subjective measures of relative standing, as information is collected on individuals’ perceptions of where they rank in the income distribution. We find considerable differences between objective and subjective measures of an individual’s relative ranking. Furthermore, our results suggest that an individual’s perceived relative status has a significantly larger effect on subjective well-being than objective measures of relative status based on reported income. We also examine the effects on subjective well-being of how individuals perceive their relative position in the income distribution to have changed since childhood, and what they expect their relative position to be in the future. We find that future upward mobility has a smaller effect than upward mobility compared to one’s past, suggesting that life satisfaction is influenced more by what has been achieved than by anticipated achievements.     

Education Expansion, Educational Inequality, and Income Inequality: Evidence from Taiwan, 1976–2003

The expansion of higher education in Taiwan starting from the late 1980s has successfully raised the average level of education. Using the concept of the education Gini, we find that the educational inequality declined as average schooling rose during the period of 1976–2003. The impacts of a rising average schooling and a declining educational inequality are also tested empirically in this paper. The evidence supports that a higher level of average schooling will generate a lower income inequality. On the other hand, a lower educational inequality, as measured by education Gini coefficient, will also cause a lower income inequality. Skill-biased technological change that shifts the labor demand from unskilled workers toward skilled workers is the most likely cause for the rising income inequality in Taiwan. However, the trend of rising income inequality could be reversed due to possible future over-education and unemployment in the labor market.     

Deprivation,Social Exclusion and Subjective Well-Being

This paper aims at investigating empirically the relationship between self-declared satisfaction with life and an individual’s well-being as measured by the indices of deprivation and social exclusion proposed in the income distribution literature. Results on European countries show that life satisfaction decreases with an increase in deprivation and exclusion after controlling for individual’s income, relative income and other influential factors in a multivariate setting.     

Income Inequality and its Consequences for Life Satisfaction: What Role do Social Cognitions Play?

While it is generally agreed that income inequality affects an individual’s well-being, researchers disagree on whether people living in areas of high income disparity report more or less happiness than those in more equal environments, thereby indicating the need to study how and why income inequality matters to the individual’s well-being. Findings on group-specific reaction patterns to income inequality further fuel this need. Alesina et al. (2004) argue that a preference for inequality and the perception of the possibility of social mobility account for the indistinct relationship between income inequality and subjective well-being. Combining this hypothesis with previous research on social cognition and drawing on social justice theory, this paper aims to demonstrate the mediating nature of perceptions of income inequality. It argues that the perceived legitimacy of distributive outcomes and procedures contributes to how income inequalities affect individuals and their sense of well-being. The empirical analysis is based on data from the International Social Justice Project, developed from face-to-face interviews with a representative sample of the German population. Using structural equation modeling, the paper finds structural biases in the perception of income inequality. The paper concludes that subjective well-being is a product of the individual’s perception and legitimating processes. The results indicate that social cognition is a useful tool for studies of income inequality and subjective well-being.     

中国农村儿童健康不平等及其影响因素研究——基于CHNS数据的经验研究

本文使用“中国家庭营养与健康调查”（CHNS）数据,测度了中国农村儿童健康不平等程度,重点计算了收入、医疗保险、母亲教育水平等因素对健康不平等的贡献。回归基础上的集中系数及其分解结果显示：我国农村地区存在亲富人的健康不平等,高收入家庭儿童的健康状况更好;健康不平等主要的贡献因素是父母亲收入、母亲教育程度、母亲工作状况、父亲身高等：收入对于儿童健康不平等的贡献最大,但不同的收人类型表现出一定的差异。父母亲的工资收入对于儿童健康不平等的贡献为正,收入不平等会扩大健康不平等;医疗保险的不平等程度不断扩大,进一步强化了健康不平等。     

Income Affluence in Poland

This paper examines the evolution of income affluence (richness) in Poland during 1998–2007. Using household survey data, the paper estimates several statistical indices of income affluence including income share of the top percentiles, population share of individuals receiving incomes higher than the richness line, and measures that take into account both the extent and the intensity of affluence. Results show that over the period under study there was a statistically significant and socio-economically sizable rise in income affluence by between 9 and 50%, depending on the index used. The overall income distribution in the period has shifted in favour of the rich as relative poverty and relative size and income share of the middle class have declined.     

Fringe benefits and income inequality

In this paper, we analyze the distribution of fringe benefits among workers and underline its implications for income inequality. To this end, we develop a positional approach to inequality based on the concept of rent as a potential link between positions and their rewards. We hypothesize that workers extract rent in the form of benefits in industries with worker leverage (in the form of unioniziation, internal labor market, and public employment) or share rent with firms in highly profitable industries that endure for efficiency wage reasons. On the basis of a unique dataset from Israel, we test these hypotheses by estimating the probabilities of obtaining benefits according to industries’ structural features while controlling for cross-industrial differences in workers’ demographic and human capital characteristics. The analyses reveal that benefits are determined by structural factors, representing a separate dimension of the rewards attached to positions, different from earnings. We further stress the importance of incorporating fringe benefits into inequality research, given that benefits together with earnings stratify workers and evidently signify structured positions in the economy.     

Ways by which Comparable Income Affects Life Satisfaction in Hong Kong

Proponents of social equality attribute low life satisfaction to income inequality in society, an inequality which occurs when most people have relatively low income and only a few have high income. In contrast, range-frequency theory and other social comparison theories predict that when most people have low income, they are satisfied because of the absence of relative deprivation among themselves. This prediction essentially suggests that that the size of the group of individuals with comparable income (i.e., income parity) sustains their life satisfaction. This theoretical prediction, however, does not consider their desire to be distinctive. By incorporating the notion of optimal distinctiveness, the size of income parity may have a quadratic effect on the individual’s life satisfaction. This is a hypothesis that receives support from the present study in Hong Kong, China. The study finds a saddle point of income parity size associated with the lowest life satisfaction, other things being equal. Furthermore, middle-income individuals have income parity size equal to or above this saddle point. They would have higher life satisfaction with increased income parity size, which therefore leads to a more enlarged income inequality. Others, however, may have higher life satisfaction with reduced income parity size. Hence, reducing income inequality would have mixed effects on people with different levels of income.

The McMansionization of America? Income stratification and the standard of living in housing, 1960–2000

Consumption patterns and living standards are relatively neglected in stratification research even though they are important indicators of material well-being. Consumption inequality is related to income and wealth disparities through complex processes not yet well understood. This paper addresses this gap by analyzing a striking shift in the standard of living in housing in the US that occurred at the same time as a substantial increase in income inequality. Houses became significantly bigger in the 1980s and 1990s just as inequalities deepened, reversing an earlier trend towards smaller houses. Diverse theoretical traditions in the consumption and housing stratification literatures explain this shift differently, and in particular posit very different effects of rising income inequality. I derive several alternative expectations from these traditions: two predicting that the increasing size of houses was broadly shared across income levels, while another expects it represented increasing divergence in living standards, paralleling the trend in income inequality. I use US Census and American Housing Survey data and several different methods to adjudicate between these theories. The results provide some support for each of the alternative expectations, but the most significant finding is that big house ownership became more concentrated among the affluent. A focus on living standards thus uncovers a key source of rising disparities at the turn of the 21st century with important implications for wealth stratification too since houses are the major debt and asset held by most Americans.     

Knowing One’s Lot in Life Versus Climbing the Social Ladder: The Formation of Redistributive Preferences in Urban China

This paper examines, how individual preferences for redistribution in general and redistribution to improve access to education, improve social protection for the poor, reduce income inequality and reduce unemployment depend on beliefs about what determines one’s lot in life and self-assessed prospects for climbing the social ladder in urban China. We find that beliefs about what determine one’s lot in life and subjective perceptions of future mobility are correlated with preferences for redistribution. We find that those who believe one’s lot in life is outside their control are generally more likely to favour redistribution. We show that this result is consistent with the existence of an altruism effect among the rich and entitlement effect among the poor. These findings are robust to the inclusion of control variables for the respondent’s personal characteristics and the location in which he or she lives.     

Testing the relationship between income inequality and life expectancy: a simple correction for the aggregation effect when using aggregated data

In this paper, we show a simple correction for the aggregation effect when testing the relationship between income inequality and life expectancy using aggregated data. While there is evidence for a negative correlation between income inequality and a population’s average life expectancy, it is not clear whether this is due to an aggregation effect based on a non-linear relationship between income and life expectancy or to income inequality being a health hazard in itself. The proposed correction method is general and independent of measures of income inequality, functional form assumptions of the health production function, and assumptions on the income distribution. We apply it to data from the Human Development Report and find that the relationship between income inequality and life expectancy can be explained entirely by the aggregation effect. Hence, there is no evidence that income inequality itself is a health hazard.     

The Impact of Fathers’ Work and Family Conflicts on Children’s Self-Esteem: The Hong Kong Case

Work and family conflicts are always viewed as issues of human resource management or occupational health. Insufficient attention has been focused on the impact on child development and quality of parenting, especially regarding the impact of a father’s work. To examine the impact of work and family conflicts on the quality of father–child interactions in Hong Kong, a cross-sectional survey was conducted. In total, 556 pairs of working fathers and their school-aged children participated in the survey. The findings of the survey indicated that fathers’ work-to-family conflicts negatively affected the quality of father–child interactions, which in turn caused harm to children’s self-esteem. In addition to work-family conflicts, a low income level of the fathers, a larger number of children in the family, and the presence in the family of children approaching adolescence were significant risk factors to the quality of father–child interactions. The mothers’ active parental involvement and the complexity of the fathers’ occupation were significant protective factors of the quality of father–child interactions. To facilitate strong family bonding and good quality parenting, possible measures to ensure a healthy work-family balance among working fathers are discussed.     

Income inequality and self-rated health status: Evidence from the european community household panel

We examine the effect of income inequality on individualś self-rated health status in a pooled sample of 11 countries, using longitudinal data from the European Community Household Panel survey. Taking advantage of the longitudinal and cross-national nature of our data, and carefully modeling the self-reported health information, we avoid several of the pitfalls suffered by earlier studies on this topic. We calculate income inequality indices measured at two standard levels of geography (NUTS-0 and NUTS-1) and find consistent evidence that income inequality is negatively related to self-rated health status in the European Union for both men and women, particularly when measured at national level. However, despite its statistical significance, the magnitude of the impact of inequality on health is very small.     

Understanding changes in Māori incomes and income inequality 1997–2003

This paper examines recent changes in weekly income levels and dispersion for Māori, New Zealand’s indigenous ethnic group. Changes in the Māori income distribution between 1997 and 2003 reflect rapid increases in economic growth and employment rate. A reduced proportion of people had zero or benefit-level incomes and a higher proportion had high incomes. Income inequality declined for working-aged Māori and was stable for employed Māori. The average income gap between Māori and Europeans declined. The increased Māori employment rate during this period was the single most important driver of changes in the Māori income distribution.

Income and inequality as determinants of mortality: An international cross-section analysis

This paper analyses the effects of income and income distribution on mortality. The likely relation between income and mortality for individuals is discussed, and implications for the determinants of mortality at the community level inferred. Measures of income inequality are likely to be related to mortality on aggregate data because of the non-linearity of income effects. An international cross-section analysis is then undertaken in which different measures of income and income distribution are investigated as determinants of mortality, with life expectancy at birth and age five, and infant mortality taken as measures of the dependent variable. It is found that income distribution is consistently and strongly related to mortality; in a relatively inegalitarian country life expectancy may be between five and ten years lower than in a more egalitarian country.

Relative Income and Happiness in Asia: Evidence from Nationwide Surveys in China, Japan, and Korea

This study attempts to examine relative income effects on perceived happiness in three major Asian countries—China, Japan, and Korea—in comparison with the United Sates, on the basis of largely comparable nationwide surveys in these countries. Consistent with the results from previous studies in Western countries, comparisons with an individual’s own income and average income of the reference group are significantly associated with the individual’s perceived happiness in Asia. The associations between relative income and happiness are stronger for individual income than family income in China, while the opposite is true in Japan and Korea. Even after controlling for the subjective assessment of family income or personal class identification within the society as a whole, income comparisons within the reference group matter for assessing happiness, especially when using family income for comparisons. Moreover, relative deprivation within the reference group, which is measured by the Yitzhaki index, is negatively related to happiness, providing more evidence for the validity of the relative income hypothesis.
