基尼系数的局限性及其补充:中国经验

使用国际上通用的基尼系数分析收入差距,是有一定的适用范围和条件的,而且基尼系数自身也存在一定的局限性。目前在全国范围内计算的基尼系数,忽略了中国作为一个发展中大国存在空间、地域等异质性因素,如果直接套用“0．4的国际警戒线”,会在政策的制订上带有一定的盲目性。基尼系数在中国的适用过程中,必须充分考虑到大规模人口流动因素对城乡收入差距、地区收入差距扩大的抑制效应甚至缓解作用。只有将经济增长标准、收入流动性标准、社会承受力标准以及收入差距预警系统建设等这些指标和工具作为对基尼系数分析的有效补充,才能够确保对中国收入差距的判断和度量更加科学、有效。     

Childhood poverty dynamics and adulthood overweight/obesity: Unpacking the black box of childhood

Integrating several life course models, this study examines how childhood poverty dynamics shape the risk of adulthood overweight/obesity. Growth mixture models of yearly poverty data from age 0–16 from the U.S. Panel Study of Income Dynamics identify four childhood poverty trajectories: chronic poverty, early childhood poverty, downward mobility, and poverty-free. Chronic poverty and early childhood poverty groups have higher risk of adulthood overweight/obesity than the poverty-free group. Overweight/obesity risk is not significantly different between the chronic poverty group and the early childhood poverty group, suggesting that the effects of early childhood exposure persist despite subsequent upward mobility. Downward mobility in the absence of early childhood poverty does not significantly increase adulthood obesity risk, providing further evidence that early childhood is a critical period for developing risk of overweight and obesity. These findings shed new light on the timing model, social mobility model, cumulative model, and cumulative inequality theory.

Diverging fortunes? Economic well-being of Latinos and African Americans in new rural destinations

The geographic diffusion of Latinos from immigrant gateways to newly-emerging rural destinations is one of the most significant recent trends in U.S. population redistribution. Yet, few studies have explored how Latinos have fared in new destinations, and even fewer have examined economic implications for other minority workers and their families. We use county-level data from the 1990 and 2000 U.S. Census and the 2006–2010 American Community Survey to compare the changing economic circumstances (e.g., employment and unemployment, poverty, income, and homeownership) of Latinos and African Americans in new Latino boomtowns. We also evaluate the comparative economic trajectories of Latinos in new destinations and established gateways. During the 1990s, new rural destinations provided clear economic benefits to Latinos, even surpassing African Americans on some economic indicators. The 2000s, however, ushered in higher rates of Latino poverty; the economic circumstances of Latinos also deteriorated more rapidly in new vis-à-vis traditional destinations. By 2010, individual and family poverty rates in new destinations were significantly higher among Latinos than African Americans, despite higher labor force participation and lower levels of unemployment. Difference-in-difference models demonstrate that in both the 1990s and 2000s, economic trajectories of African Americans in new Latino destinations largely mirrored those observed in places without large Latino influxes. Any economic benefits for Latinos in new rural destinations thus have not come at the expense of African Americans.     

Is happiness inequality immune to income inequality? New evidence through instrument-effect-corrected standard deviations

Previous research has found that a nation’s income inequality does not affect its happiness inequality. This article questions the appropriateness of the standard deviation as measure of happiness inequality used in these studies. Our main criticism concerns structural dependency, i.e. the technical dependency of the standard deviation on a nation’s mean happiness which is induced by measuring happiness with limited rating scales. To overcome this drawback, two new measures are proposed which adjust for the effects of limited instruments. Applying these new measures to the most recent World Values Survey data demonstrates that some countries change their ranking in the league table of happiness inequality considerably. Moreover, income inequality does affect corrected happiness inequality, a finding which has significant public policy implications.

Educational differences in mortality associated with central obesity: Decomposing the contribution of risk and prevalence

Thousands of preventable deaths are attributed to obesity in the United States. However, the harmfulness of obesity varies across the population; individuals’ education determines access to healthful resources and exposure to competing risks, dampening/amplifying obesity-associated mortality risk. Using restricted U.S. National Health and Nutrition Examination Survey data (N = 40,058; 1988–2015), this study estimates educational differences in mortality attributable to central obesity (waist-to-height ratio ≥0.5) – a dangerous form of abdominal adiposity. Over 30% of excess deaths are attributable to central obesity among college-educated adults, compared to 1–10% among their less-educated counterparts. This difference is larger for cardiometabolic-related mortality, as central obesity may explain 60–70% of excess deaths among college-educated adults. Decomposition analyses show differences are driven by greater obesity-associated risk among college-educated adults, rather than prevalence. Policies targeting health disparities should recognize central obesity as a key risk among highly-educated adults, but only one of many encountered by those with less education.     

Inequality and inequity

Kelley and Evans (2017) found that income inequality (measured at the societal level) did not affect individual well-being in advanced societies but increased individual well-being in developing societies. This paper discusses how this empirical patterning of the inequality-well-being relationship may arise from mechanisms related to the relationship of inequality with economic development (at the macro-sociological level) and to the evolution of emotional reactions to inequality (at the individual-psychological level).     

中国三大区域间收入不平等影响因素的实证研究:1952-2008

区域收入不平等的持续增大,对个人与群体的尊严、国家经济的可持续性发展形成严峻挑战。以往研究局限于经济学视角,只关心某一或某几种因素对收入不平等影响,过于碎片化。本文利用1952-2008年国家统计数据,基于结构主义视角,通过随机效应模型考察了区域间收入不平等背后的因果机制。研究发现:经济增长与区域间收入不平等存在微弱倒"U"关系;结构因素是构筑区域收入不平等的主要力量,解释比例达到69.7%。本文认为,"非均衡发展"是中国经济转型与发展过程中必然的路径选择,区域收入不平等不可避免,并将长期存在。     

Is immigrant neighborhood inequality less pronounced in suburban areas?

We investigate suburbanization and neighborhood inequality among 14 immigrant groups using census tract data from the 2008–2012 American Community Survey. Immigrant neighborhood inequality is defined here as the degree to which immigrants reside in neighborhoods that are poorer than the neighborhoods in which native whites reside. Using city and suburb Gini coefficients which reflect the distributions of groups across neighborhoods with varying poverty rates, we find that the immigrant-white gap is attenuated in the suburbs. This finding applies to most of the nativity groups and remains after accounting for metropolitan context, the segregation of poverty, and group-specific segregation levels, poverty rates, and acculturation characteristics. Despite reduced neighborhood inequality in the suburbs, large group differences persist. A few immigrant groups achieve residential parity or better vis-à-vis suburban whites while others experience high levels of neighborhood inequality and receive marginal residential returns on suburban location.     

Unequal on top: Gender profiling and the income gap among high earner male and female professionals

We develop a comprehensive, multi-level model of income inequality between high earner men and women during the early career stages. We argue that young women are routinely subjected to “gender profiling” by employers—women’s potential contribution to the organization is interpreted through the lens of social stereotypes and cultural norms that attribute to them weaker labor market commitment than men. We investigate two specific mechanisms that arise from this profiling and lead to income inequality: First, women have diminished access to resources and advancement opportunities within the firm which results in lower returns to tenure for women than for men. Second, external mobility is greatly beneficial for men but much less so for women because it reinforces the image of weak commitment. Salary regressions of early career history data of young MBA alumni of a prestigious U.S. business school accord with our conjectures.     

Race,deprivation, and immigrant isolation: The spatial demography of air-toxic clusters in the continental United States

This article contributes to environmental inequality outcomes research on the spatial and demographic factors associated with cumulative air-toxic health risks at multiple geographic scales across the United States. It employs a rigorous spatial cluster analysis of census tract-level 2005 estimated lifetime cancer risk (LCR) of ambient air-toxic emissions from stationary (e.g., facility) and mobile (e.g., vehicular) sources to locate spatial clusters of air-toxic LCR risk in the continental United States. It then tests intersectional environmental inequality hypotheses on the predictors of tract presence in air-toxic LCR clusters with tract-level principal component factor measures of economic deprivation by race and immigrant status. Logistic regression analyses show that net of controls, isolated Latino immigrant-economic deprivation is the strongest positive demographic predictor of tract presence in air-toxic LCR clusters, followed by black-economic deprivation and isolated Asian/Pacific Islander immigrant-economic deprivation. Findings suggest scholarly and practical implications for future research, advocacy, and policy.     

Income inequality and participation: A comparison of 24 European countries

Previous research suggests that when there is a high level of inequality, there is a low rate of participation. Two arguments are generally offered: First, inequality depresses participation because people from different status groups have fewer opportunities to share common goals. Second, people may participate more in civic and social life when they have more resources. However, until now, these explanations have not been separated empirically. Using EU-SILC data for 24 European countries, we analyze how income inequality is related to civic and social participation. Our results indicate that the main effects of inequality manifest via resources at the individual and societal level. However, independent of these resources, higher inequality is associated with lower civic participation. Furthermore, inequality magnifies the relationship between income and participation. This finding is in line with the view that inter-individual processes explain why inequality diminishes participation.     

Economic performance and public concerns about social class in twentieth-century books

What is the association between macroeconomic conditions and public perceptions of social class? Applying a novel approach based on the Google Books N-gram corpus, this study addresses the relationship between public concerns about social class and economic conditions throughout the twentieth century. The usage of class-related words/phrases, or “literary references to class,” in American English-language books is related to US economic performance and income inequality. The findings of this study demonstrate that economic conditions play a significant role in literary references to class throughout the century, whereas income inequality does not. Similar results are obtained from further analyses using alternative measures of class concerns as well as different corpora of English Fiction and the New York Times. We add to the social class literature by showing that the long-term temporal dynamics of an economy can be exhibited by aggregate class concerns. The application of massive culture-wide content analysis using data of unprecedented size also represents a contribution to the literature.

Income inequality,distributive fairness and political trust in Latin America

In the wake of rising levels of income inequality during the past two decades, widespread concerns emerged about the social and political consequences of the widening gap between the poor and the rich that can be observed in many established democracies. Several empirical studies substantiate the link between macro-level income inequality and political attitudes and behavior, pointing at its broad and negative implications for political equality. Accordingly, these implications are expected to be accentuated in contexts of high inequality, as is the case in Latin America. Despite these general concerns about the consequences of income inequality, few studies have accounted for the importance of individual perceptions of distributive fairness in regard to trust in political institutions. Even less is known about the extent to which distributive fairness perceptions co-vary with objective indicators of inequality. Moreover, the research in this area has traditionally focused on OECD countries, which have lower indexes of inequality than the rest of the world. This study aims at filling this gap by focusing on the relevance of distributive fairness perceptions and macro-level inequality for political trust and on how these two levels interact in Latin American countries. The analyses are based on the Latinobarometer survey 2011, which consists of 18 countries. Multilevel estimations suggest that both dimensions of inequality are negatively associated with political trust but that higher levels of macro-level inequality attenuate rather than increase the strength of the negative association between distributive fairness perceptions and political trust.     

Inequality of educational opportunity in France and the United States

Unequality of educational opportunity is related to school structure. Comparison of the attainment process in France and the United States reveals the consequences of structure for individuals' attainments. Turner's (1960) typology of educational systems is applied. The French educational system is shown to be closer to Turner's “sponsorship system,” and that of the U. S. closer to the “contest” type. Inequality of educational opportunity, as indicated by the effect of father's occupational status on years of schooling completed, is greater in France than in the U. S. The difference is accounted for by school structural variables, indicating the importance of structure for inequality of opportunity. Other differences concerning the causes of educational attainment in France and the U. S. are also discussed.     

Revisiting convergence: A research note

A number of recent studies show that income inequality is declining between countries. In this research note, I question the significance of this trend by examining the role of initial conditions in producing convergence. An important (but neglected) property of inequality dynamics is the tendency for extreme distributions to become more moderate. When income disparities are large, the subsequent trend is biased toward convergence. Conversely, when initial conditions approach parity, divergence becomes the more likely long-term outcome. I apply this principle to trends in GDP PC across 127 countries during the 1980–2010 period. Using counterfactual analysis, I manipulate the initial level of inequality in GDP PC while holding constant each country’s observed growth rate during the sample period. I find that the growth dynamics of GDP PC produce either convergence or divergence based simply on the initial distribution of income. The point of transition occurs at a moderate level of inequality, whether using population weights (Gini = .365) or not (Gini = .377). I conclude that the recent convergence observed in GDP PC is primarily a function of large income gaps between countries and would not have materialized at more moderate levels of initial inequality. By contrast, an examination of the pre-1950 period reveals divergent growth patterns that are not sensitive to initial conditions.     

Societal Inequality and individual subjective well-being: Results from 68 societies and over 200,000 individuals, 1981–2008

Income inequality has been contentious for millennia, a source of political conflict for centuries, and is now widely feared as a pernicious “side effect” of economic progress. But equality is only a means to an end and so must be evaluated by its consequences. The fundamental question is: What effect does a country's level of income inequality have on its citizens' quality of life, their subjective well-being? We show that in developing nations inequality is certainly not harmful but probably beneficial, increasing well-being by about 8 points out of 100. This may well be Kuznets's inverted “U”: In the earliest stages of development some are able to move out of the (poorly paying) subsistence economy into the (better paying) modern economy; their higher pay increases their well-being while simultaneously increasing inequality. In advanced nations, income inequality on average neither helps nor harms. Estimates are from random-intercept fixed-effects multi-level models, confirmed by over four dozen sensitivity tests. Data are from the pooled World Values/European Values Surveys, Waves 1 to 5 with 169 representative national samples in 68 nations, 1981 to 2009, and over 200,000 respondents, replicated and extended in the European Quality of Life Surveys.     

对中国制造业区域集聚水平的判断——兼论地区间产业是否存在同构化倾向

从集聚的不同内涵出发,选择制造业二位数行业与四位数行业在县级层面的空间分布为研究对象,以行业基尼系数与地区Hoover系数为指标,详细分析目前中国制造业的空间分布状况,对长期以来学界关于区域集聚水平较低、地区间产业存在同构化倾向的论争做出明确回应,具有重要的理论意义和现实意义。研究结果显示,制造业各行业在县级经济体的分布是不平衡的,县级经济体的专业化倾向明显,其行业基尼系数与地区Hoover系数均处于较高水平。因此,在继续保持县级经济体的专业化水平的基础上,大力发展大中型城市是解决制造业产能过剩等问题的着眼点。
