Dynastic Inequality Compared: Multigenerational Mobility in the United States,the United Kingdom,and Germany

Using harmonized household survey data, we analyze long‐run social mobility in the United States, the United Kingdom, and Germany, and test recent theories of multigenerational persistence of socioeconomic status. In this country comparison setting, we find evidence against a universal law of social mobility. Our results show that the long‐run persistence of socioeconomic status and the validity of a first‐order Markov chain in the intergenerational transmission of human capital is country‐specific. Furthermore, we find that the direct and independent effect of grandparents' social status on grandchildren's status tends to vary by gender and institutional context.     

Income Mobility and Income Inequality in Rural China

The economic literature has argued for a long time that income mobility could attenuate the degree of cross-sectional inequality by offering people opportunities to improve their socio-economic position. Using the longitudinal data from the China Health and Nutrition Survey (CHNS) from 1989 to 2011, we measure income mobility as the degree to which longer-term incomes are distributed more or less equally than yearly income. Five main results are emphasized. First, there is strong income mobility in rural China that partly offsets yearly income inequality. Second, income mobility has decreased since the 2000s, indicating that income distribution is becoming more rigid. Third, mobility is mainly associated with transitory income fluctuations, particularly in the two tails of the distribution. Fourth, income mobility has an equalizing effect on income distribution. Fifth, we show that non-agricultural income mobility has substantially increased over the period and that its equalizing nature has also recently increased. While the development of the non-agriculture sector in rural China was a crucial factor in explaining the increase in rural inequality until the mid-2000s, we suggest that the large-scale generalisation of such non-agricultural opportunities partly accounts for the decline in rural inequality observed since the mid-2000s.     

Income Mobility, Inequality and Social Welfare

It is often argued that an observation of rising annual income inequality need not have negative normative implications. The argument is that if there has been a sufficiently large simultaneous increase in mobility, the inequality of income measured over a longer time period can be lower despite the rise in annual inequality. In this paper, it is shown by example that if normative implications are drawn from a standard social welfare function, the set of circumstances put forward in the above argument are not sufficient to guarantee that social welfare will improve. The reason is that even though rising mobility does reduce longer term inequality, it also increases the variability of income profiles over time and the latter has a detrimental social welfare effect. Hence, there are two types of mobility: one which reduces inequality (regression to the mean), but another that increases inequality (relative movements uncorrelated with incomes). Further, if individuals' aversion to income variabiltiy is sufficiently larger than the social welfare judge's aversion to inequality, then an increase in mobility, no matter how large, cannot offset the negative normative effect of rising annual inequality.     

Income Inequality in OECD Countries: Data and Explanations

There is much disagreement about both the facts and the explanationsof income inequality. Even if we confine attention to OECD countries,we find people arguing that there has been a great U-turn, withinequality rising sharply after its post war fall, and otherswho believe that the speed of change is glacial. In order toevaluate the historical record, we need data for a long runof years. The present paper reviews evidence about coveringthe period 1945–2001 for nine OECD countries. It is widelybelieved that rising inequality is attributable to technologicalchange and to globalisation. The second part of the paper arguesthat these are only part of a complex story. Household incomesdepend on public policy and on sources of income apart fromwork. What is happening at the top of the distribution may needto be explained quite differently. (JEL H0, E6)     

Household Income Inequality and Income Mobility: Implications Towards Equalizing Longer-Term Incomes in India

This paper addresses three important questions. First, what are the trends, levels and sources of income inequality in India? Second, how have been the patterns of income mobility? And finally, exploring the relationship between income mobility and income inequality in the context of India. Results, based on recent India Human Development Survey (IHDS) longitudinal data, advocate that not only is income inequality very high, nonetheless, it has increased – mainly attributable to different income sources – in India. The paper also focused on whether or not this income mobility equalizes longer-term incomes. Results suggest income mobility has resulted in-albeit not robust- equalizing longer-term incomes. Thus, based on imperative findings, the paper suggests, the nature of longer-term well-being is crucial to designing policy interventions to effectively tackle inequality and in this context, economic mobility can be seen as an avenue to long-term equality.     

Income inequality and crime in the United States

This paper investigates the relationship between income inequality and crime. Results show that there is a strong and robust effect of relative income inequality on burglary. Effect on robbery is also strong and robust in most cases.     

Accounting for United States Household Income Inequality Trends: The Changing Importance of Household Structure and Male and Female Labor Earnings Inequality

Using a shift‐share analysis on March CPS data, this paper estimates the degree to which changes in labor earnings, employment, and marriage patterns account for household income inequality growth in the United States since 1979. The factors contributing to the rapid rise in income inequality in the 1980s differ substantially from those contributing to its slower increase since that time. Unlike findings for the 1980s when changes in the correlation of spouses' earnings accounted for income inequality growth, this factor is no longer a major contributor toward its continued increase. Additionally, the 2000s business cycle is the first full business cycle in at least 30 years where changes in earnings of male household heads accounted for declines in income inequality. Instead, the continued growth in income inequality in the 2000s was accounted for primarily by increases in female earnings inequality and declines in both male and female employment.     

European Integration and Inequality among Countries: A Lifecycle Income Analysis

This paper analyzes the effects of the enlargements of the European Union on inequality using an approach based on individuals' lifecycle incomes. This allows one to consider the effect of different rates of growth and survival rates. Inequality in terms of permanent income was substantially less than in current per capita income at the time of all the enlargements except those of the last 10 years. The results point to the key role of policies that stimulate growth in the less developed countries. With an annual β‐convergence of 2% in current income, inequality in permanent income would be less than one third of what it is now.     

Income Inequality and Technology Diffusion: Evidence from Developing Countries*

We study the effect of within‐country income inequality on the diffusion of mobile phones using data on market penetration in a sample of developing countries from 1985 to 1998. Mobile phones are an example of international technology, originating in industrialized countries and diffusing worldwide. We find that income inequality, as measured by the income share of the highest earning deciles, has a positive effect on the early diffusion of mobile phones and that the estimated effect becomes greater when a measure of agricultural endowments is used as an instrument. The instrumental variable results are robust to weak instruments. Our findings suggest that the diffusion of new technologies originating from industrialized countries may generate yet another channel that links inequality and development.     

Income mobility of individuals in China and the United States

Although much has been written about annual income inequality in China, little research has been conducted on longer‐run measures of income inequality and on income mobility. This paper compares income mobility of urban individuals in China and the United States in the 1990s. The following questions are taken up: To what extent are measures of annual income inequality misleading indicators of long‐run income inequality? How much income mobility was there in China in the first half of the 1990s and how did this compare with mobility in other countries? Have real income increases been greater for the poor or the rich? How important is the variation in permanent incomes in China and how has this changed?     

Sexual Orientation,Sexual History,and Inequality in the United States

Much of the literature on sexual orientation discrimination reports earnings differentials for gay, lesbian, and bisexual individuals when compared with heterosexuals. The General Social Survey (GSS) has previously been used due to its extensive coverage of demographic variables and sexual behavior in the United States. This study uses updated GSS data to investigate whether the income differentials found in earlier work have persisted and how estimates based on categorizing respondents according to the reported sex of their sex partners compare to estimates based on the respondents’ self-reported sexual orientation. Results for the years 2008–14 indicate that self-identification as an LGB individual and/or same-sex sexual behavior are correlated with a lower income; however, not all the results are statistically significant. In addition, there is a statistically significant negative income differential of 32 percent for men who report having had a same-sex partner at some point, but identify as straight/heterosexual.     

Sources of Inequality: Measuring the Contributions of Income Sources to Rising Family Income Inequality

We develop a simulation method for measuring the impact of changes in the distributions of the main income sources on growth in family income inequality. We simulate the entire distribution of family income under the counterfactual, “What if the distribution of each source had not changed?” The simulation method allows us to evaluate the impact of changes at any point in the distribution as well as with multiple measures of inequality. We incorporate married‐couple and single‐person families, appropriately accounting for changes in the proportion married. We apply the simulation method to investigate the impact of changes in male earnings, female earnings, and capital income on the distribution of family income in the United States between 1969 and 1999. We find that changes in the distribution of male earnings account for more of the growth in family income inequality than do changes in any other source of income. Changes in the distribution of female earnings have reduced family income inequality.     

收入流动性与我国居民长期收入不平等的动态变化:基于CHNS数据的分析

收入不平等是世界各国面临的共同难题.大多数文献在分析收入不平等时,通常是以年度截面收入为基础进行估算的,而如果考虑到收入流动性的存在,长期收入不平等程度将可能有所减小.文章的研究显示:根据CHNS提供的数据,通过居民收入5等分转换矩阵可以看出,由于收入流动性的存在,各收入层级长期收入所占份额较为接近,长期收入的基尼系数也大大低于年度平均值.文章还以Shorrocks平等化指数量化了收入流动性对长期收入不平等的影响,发现1989-2011年期间,收入流动性使以长期收入衡量的不平等程度降低了24.4％,但近年来,收入流动性出现了下降趋势,抑制了长期收入的平等化.由于收入流动性会影响到长期收入的不平等,因此建议通过深化改革公共政策和提高居民受教育程度来提高流动性,进而实现长期收入平等.     

The Meritocratic Elite vs. the Common Man: Income Inequality in the Affluent OECD Countries

Our goal is to highlight the relationship between vested interests of the meritocratic elite and the deteriorating situation of the common man. We provide an example of rising income inequality in selected OECD countries over the past thirty years. Income inequality is growing, despite the increase in labor productivity based on technological progress, which we prove by using robust panel regression models. Our findings could be explained by the effect of “extreme meritocracy” that describes a situation in which wages for “the working rich” are growing faster than their productivity, and creating wage stagnation for the middle-class workers.     

Occupational Mobility and Wage Inequality

In this article we argue that wage inequality and occupational mobility are intimately related. We are motivated by our empirical findings that human capital is occupation specific and that the fraction of workers switching occupations in the U.S. was as high as 16% a year in the early 1970's and had increased to 21% by the mid-1990's. We develop a general equilibrium model with occupation-specific human capital and heterogeneous experience levels within occupations. We find that the model, calibrated to match the level of occupational mobility in the 1970's, accounts quite well for the level of (within-group) wage inequality in that period. Next, we find that the model, calibrated to match the increase in occupational mobility, accounts for over 90% of the increase in wage inequality between the 1970's and the 1990's. The theory is also quantitatively consistent with the level and increase in the short-term variability of earnings.     

1870-2009年美国的功能收人分配及启示

该文从功能收入分配的视角考察了1870年以来美国收入分配的变化。实证研究表明,美国劳动份额从1870年的50%上升到2009年的71.6%;同期,资产和业主份额由50%下降到28.4%。美国劳动份额一直上升的实践,并不符合劳动报酬变化U形规律(即劳动份额先下降后上升)的假说。这一结论的含义是,以经济发展阶段来推理收入分配差距某种必然性的假说是不可靠的,这意味着我们必须从经济增长或发展以外的其他因素中去寻求新的解释。     

Consumption and Income Inequality in Australia

Consumption may be a more appropriate measure of household well-being than income or earnings. Using four ABS Household Expenditures Surveys collected between 1975 and 1993, we compare trends in consumption and income inequality among Australian households. We find that consumption is much more equal than income. While there were significant increases in both income and consumption inequality, consumption inequality rose by much less. One interpretation of the results is that some income inequality in Australia reflects transitory fluctuations which households can smooth,'and that part of the growth in income inequality reflects an increase in these transitory fluctuations.     

Wage Inequality and Wage Mobility in Europe

Using data from the European Union Statistics on Income and Living Conditions, this paper investigates wage inequality and wage mobility in Europe. Decomposing inequality into within‐ and between‐group inequality, we analyze to what extent wage inequality and mobility can be explained by observable characteristics. Furthermore, we investigate which individual and household characteristics determine transitions within the wage distribution. We find that overall, mobility reduces wage inequality. While a large part of wage inequality is due to unobservable characteristics, the equalizing effect of mobility mainly occurs within groups. Furthermore, both personal and household characteristics play an important role for wage transitions. Finally, our findings reveal large cross‐country differences across Europe.     

Is Mobility in the United States Still Alive? Tracking career opportunities and income growth

Longitudinal data are used to compute income and earnings mobility in the 1970s and 1980s. The various strengths and weakness of different perspectives on mobility are assessed, with the change in real income or earnings being chosen as the one that most closely resembles the common-sense meaning of progress or decline. Care is taken to choose the proper age ranges and to define quantiles on the basis of 10-year income or earnings. Based on the Panel Study on Income Dynamics, this paper finds the share of family income losers among prime-age adults rose from 21% in the 1970s to 33% in the 1980s. This jump is reflected in a corresponding jump in the share of male earners with declining earnings over the same time period. Female earners, however, worked 44% more in the 1980s than the 1970s and fewer were on declining earnings paths. In terms of sub-populations, lower income and less educated groups had larger increases of income and earnings losses.
