Income inequality and income segregation

This article investigates how the growth in income inequality from 1970 to 2000 affected patterns of income segregation along three dimensions: the spatial segregation of poverty and affluence, race-specific patterns of income segregation, and the geographic scale of income segregation. The evidence reveals a robust relationship between income inequality and income segregation, an effect that is larger for black families than for white families. In addition, income inequality affects income segregation primarily through its effect on the large-scale spatial segregation of affluence rather than by affecting the spatial segregation of poverty or by altering small-scale patterns of income segregation.     

Equivalence scales for extended income in the U.S

Estimates of extended household income (the sum of market income and the imputed value of non-market household production) should adjust for differences in household size and composition using equivalence scales. However, the equivalence parameters traditionally applied to market income do not plausibly apply to non-market income. Economies of scale in the relationship between living standards and household income are greater for non-market income from household production than market income, and the costs of children relative to adults are higher in household production time than in cash expenditures. Also, the presence of a full-time family caregiver significantly reduces cash expenditures on child care. This paper proposes equivalence scales that can be separately applied to the components of extended income, and demonstrates their empirical relevance with pooled data from the American Time Use Survey for 2010–2014. The proposed parameters significantly alter the relative contribution of non-market income to extended income and modify comparisons of extended income across different family household types, with particularly significant implications for the relative well-being of those with and without full-time family caregivers.     

Subjective well-being and reference-dependence: Insights from Mexico

Data from Mexico are used to examine whether two indicators of subjective well-being??income satisfaction and income adequacy??correlate not only with the respondent??s absolute level of income, but also with their assessment of how their income compares relative to the income of a reference group, the level of income they hoped to have achieved by that stage of their life, and the income they had three years earlier. Both subjective well-being indicators correlate positively with the ranking relative to all three reference points. Some of the findings differ across segments of the income distribution. Subjective well-being assessments of the poor are influenced more by the inability to achieve income aspirations, while differences with respect to others is a more prominent factor among non-poor respondents.     

Standards of Adequacy for Child Support Awards

This study examined the adequacy of child support income for children of divorce. A random sample of 186 final divorce decrees finalized in Hennepin County, Minnesota in 1986 and involving minor children were used in the analyses. Income adequacy was defined as the extent to which income provides a level of living which meets reasonable needs. Income adequacy was measured by ratios of income to income needs uding three indicators of income and three standards of needs. Income-to-needs ratios were constructed to evaluate the adequacy of child support income. Results of the study supported the assumption that the child support award did not provide a satisfactory level of income for children. This result was consistent using the actual court-ordered child support award, the amount of income which would have been given if the Minnesota guidelines had been strictly applied, or income which might have been given to the child if Wisconsin guidelines had been applied. Actual court-ordered child support awards deviated downward from the established guidelines by about $18.14 monthly. The downward deviations from guidelines were greater at higher income levels. The income-to-needs ratios of the actual court-ordered awards did not exceed 50% of the direct costs of raising children until the net annual income of the obligor exceeded $12,000-$18,000 and did not provide income over the poverty level until the obliger's income reached $24,000.     

THE LIFE-CYCLE LABOR SUPPLY OF MARRIED WOMEN AND ITS IMPLICATIONS FOR HOUSEHOLD INCOME INEQUALITY

In a life-cycle model of married womens' labor supply the husband's expected lifetime income should have a greater effect on his wife's labor supply than should his current income. Using the Panel Study of Income Dynamics data, the husband's average lifetime income (over the panel years) does have a greater negative income effect than current income. However, this income effect has declined over time: the labor supply of wives is becoming less sensitive to their husbands' incomes. This declining elasticity would cause household income inequality to worsen over time, but has been offset by other factors.     

Wealth as Security: Growth Curve Analyses of Household Income and Net Worth During a Recession

Building on evidence of increasing inequality with the 2008–2009 recession, we asked whether households experienced different financial trajectories through the recession depending on initial income and net worth. Using growth curve models of households headed by young adults in the Panel Study of Income Dynamics, we compared the relationship between initial income and net worth and the rate of change of income and net worth from 1989 to 2011 among households with income above and below $50,000. We found different patterns of income change and different relationships among income, net worth, and their rates of change between high- and low-income categories. Results suggest initial wealth helped to stabilize income and wealth changes among higher income households, reducing financial insecurity.     

The impact of household capital income on income inequality��a factor decomposition analysis for the UK, Germany and the USA

This paper analyses the contribution of capital income to income inequality in a cross-national comparison. Using micro-data from the Cross-National Equivalent File (CNEF) for three prominent panel studies, namely the BHPS for the UK, the SOEP for West Germany, and the PSID for the USA, we use the factor decomposition method described by Shorrocks (Econometrica 50:193–211, 1982). The factor decomposition of disposable income into single income components shows that capital income is exceedingly volatile and that its share in disposable income has risen recent years. Moreover, capital income makes a disproportionately high contribution to overall inequality in relation to its share in disposable income. This applies to Germany and the USA in particular. Thus capital income accounts for a large part of disparity in all three countries.     

Income Comparison as a Determining Mechanism of Class Identification: A Quantitative and Simulation Study Using Japanese Survey Data

This paper questions whether personal income comparison explains the distributive gap between income and class identification by exploring the following two issues: empirical validity of income comparison as the determinant of class identification, and theoretical validity of income comparison for the distributive gap. For the first issue, we conduct a statistical analysis using data from the Social Stratification and Social Mobility surveys (1975–2005), and the Stratification and Social Psychology-I survey (2010). We find that the criteria for choosing reference groups changed historically from residential proximity to occupational equality. In addition, income comparison with sensitive to lower-income possessors and a distorted perception of income difference significantly affected class identification, except for the year of 1985. The simulation analysis employed to examine the second issue clarified that income comparison with the above-mentioned features yields a less skewed distribution compared to that of class identification. The data also indicates that the empirical conditions of income are satisfied for realization of this result. Thus, we could ascertain empirical and theoretical validity of income comparison as explanation for the distributive gap between income and class identification.     

Long-run trends in top income shares: The role of income and population growth

This paper studies the sensitivity of long-run trends in top income shares to differences in top-share measures. While the standard measure fixes a share of the population, we define alternatives that allow variation in both incomes and size of the top group based on defining absolute income thresholds. In an application to United States data, we find that top income share trends over the past century vary somewhat depending on the measure used. Allowing top groups to increase in size after 1980 along with overall economic growth results in a larger increase of top income shares. The historical drops before WWII are sensitive to the choice of income deflator: using GDP inflates interwar top income shares but using CPI deflates them. Altogether, these results recommend using complementary approaches to defining top income groups when measuring long-term top income share trends.

     

The impact of labour income risk on household saving decisions in Turkey

This paper analyses the Household Budget Surveys prepared by the Turkish Statistical Institute to reveal the empirical importance of precautionary saving in Turkey. The most difficult aspect of the empirical analysis is the approximation of labour income risk as a proxy variable for future labour income uncertainty. Individual disposable income is interacted alternately with the probability of being unemployed and with the probability of job loss in the next period to generate the labour income risk variables. The econometric results support the precautionary saving hypothesis and labour income risk emerges as one of the main determinants of household saving decisions. Moreover, households implement alternative strategies to smooth out their income streams such as holding a second job and increasing the number of income earners in the family. However, it is evident that they are still vulnerable against labour income risk, which underlines the need for an effective and efficient social security system.     

Income characteristics and the use of microfinance services: evidence from economically active persons with disabilities

The purpose of this empirical research from Uganda is to provide initial insight into the ‘black box’ of understanding the economic behaviour of persons with disabilities and about their use of microfinance services. First, we analyse the income levels of persons with disabilities in relation to their sources of income. Second, we study the income sources and income levels for different types of disabilities. Finally, we analyse how income level and income source relate to the use of microfinance services for persons with disabilities. We present evidence that farmers with disabilities and persons with visual impairments have lower income levels than other persons with disabilities. We then document that those with the lowest income levels have the least access to microfinance services, in particular services from formal institutions. Moreover, respondents involved in farming and manufacturing have less access to formal microfinance services than those involved in retail/wholesale or service activities.     

RISING TOP INCOMES AND INCREASED BORROWING IN THE REST OF THE DISTRIBUTION

One potential consequence of rising top‐income concentration is borrowing by less‐affluent households attempting to maintain relative living standards. This paper evaluates the “keeping up with the Joneses” phenomenon, examining the responsiveness of payment‐to‐income ratios for different debt types across the income distribution to changes in income among affluent households. The analysis provides evidence for the responsiveness of debt to rising top incomes. Middle‐ and upper‐middle‐income households take on more housing‐related debt and have higher payments in places with higher top‐income levels. Among lower‐income households non‐mortgage borrowing and debt payments decline, consistent with restrictions in the supply of credit. (JEL D63, D14)     

Life satisfaction,income and personality

We use personality traits to better understand the relationship between income and life satisfaction. Personality traits mediate the effect of income on life satisfaction. The effect of neuroticism, which measures sensitivity to threat and punishment, is strong in both the British Household Panel Survey and the German Socioeconomic Panel. Neuroticism increases the usually observed concavity of the relationship: individuals with a higher neuroticism score enjoy extra income more than those with a lower score if they are poorer, and enjoy extra income less if they are richer. When the interaction between income and neuroticism is introduced, income does not have a significant effect on its own. To interpret the results, we present a simple model based on Prospect Theory, where we assume that: (i) life satisfaction is dependent on the gap between aspired and realized income, and this is modulated by neuroticism and (ii) income increases in aspirations with a slope less than unity, so that the gap between aspired and realized income increases with aspirations. From the estimation of this model we argue that poorer individuals tend to over-shoot in their aspirations, while the rich tend to under-shoot. The estimation of the model also shows a substantial effect of traits on income.     

The effects of income inequality and income level on mortality vary by population size in Texas counties

OBJECTIVES: This study uses the counties of Texas to empirically test the predictions of Wilkinson's theory on the role of income and inequality in explaining health differentials in populations. Wilkinson predicts (1) that health is affected more by income inequality than average income in areas with large population, and (2) that health is affected more by average income than income inequality in areas with small population. We investigate how large the population of a unit must be for income inequality within the unit to affect mortality. METHODS: Measures of income inequality were computed from the 1990 U.S. census data and mortality was computed from Vital Statistics data. Poisson regressions estimated the age-adjusted relative risk of the top quintile relative to the bottom quintile for equality and for income among selections of Texas counties based on population size. County ethnic composition, educational level, and health care access were controlled for. RESULTS: Among counties with populations greater than 150,000, the risk of death was lower in counties with more equal income distribution than in counties with less equal income distribution. Among counties with population less than 150,000, median income affected relative risk in counties with less than 30 percent Hispanics, but not in those with more than 30 percent Hispanics. CONCLUSIONS: This study provides some support for the predictions of Wilkinson's theory.     

The poor,the rich and the happy: Exploring the link between income and subjective well-being

The relationship between income and subjective well-being (SWB) is investigated using eight waves of the British Household Panel Survey and an estimation strategy that allows us to relax some assumptions typically made in the literature. First, we use a random effects generalised ordered probit model to investigate whether income effects are heterogeneous across SWB categories, and, second, we discretise (absolute and relative) income variables to allow for the income effects to vary across income groups. We find that higher absolute income increases SWB but up to a certain level, while low income is significantly correlated with low scores in the SWB ladder. Our results are consistent with the Easterlin Paradox that has been reported in the literature. We find that high-income groups are less likely to belong in the highest SWB level, which could be partly explained by the fact that the relative income status (rather than the absolute one) is more important in determining (the highest level of) SWB.     

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.     

Effects of Alternative Policies on Income Redistribution: Evidence from Brazil

Despite recent successes, Brazilian income (cash) transfer policies remain controversial, and alternative approaches to income redistribution are being actively considered. This article contributes to this debate, analysing the effects of several alternative policies for income redistribution in the Brazilian economy using a computable general equilibrium model. Simulations were conducted consistent with the following policies: direct transfer of income, reduction of taxes, and incentives to agricultural exports. The results suggest that transfer of income is the most effective in promoting redistribution of income, with a positive impact on the level of welfare of the poorest households.     

THE DECOMPOSITION OF INEQUALITY BY CLASS AND BY OCCUPATION:

Sociological research on earnings and income has focused on predicting individual income. Analyses most often use occupational status or class, along with other economically relevant variables, to explain earnings or income variations among individuals (income determination). Aggregate inequality (income distribution) has received considerably less attention, except in cross-national research. This especially holds for applying central concepts of stratification to the analysis of inequality. That is, class and occupation differences in economic rewards are rarely used to investigate aggregate earnings or income inequality. This study, using 1976 and 1977 Panel Study of Income Dynamics survey data, estimates the proportion of total earnings/income inequality accounted for by class and by occupation. Theil's index is used to measure earnings and income inequality and thus decompose total inequality into between-and within-group components. Wright's five-category schema is replicated for decomposition of inequality by class and a traditional four-category ordinal typology for decomposition by occupation. The two schemas show similar results: both class and occupation respectively account for between one-fifth and one-fourth of total earnings and income inequality. The results show the relevance of these central stratification typologies for the analysis of aggregate inequality.     

Socioeconomic Status and Age: The Effect of Income Sources and Portfolios on U.S. Adult Mortality

Despite the persistent inverse relationship between family income and mortality, no one has examined the effect of distinct income sources or income portfolios on mortality risk. We link the National Health Interview Survey to the Multiple Cause of Death file and use hazard models to examine income-related mortality across four age groups. Income from jobs, self-employment, interest, and dividends each predicts lower mortality at the younger, middle, and early old ages. Diverse income portfolios buffer against mortality risk at all ages, net of the amount of income received. These findings illuminate the various dimensions of income that shape U.S. mortality risks.     

Information theoretic approaches to income density estimation with an application to the U.S. income data

The size distribution of income is the basis of income inequality measures which in turn are needed for evaluation of social welfare. Therefore, proper specification of the income density function is of special importance. In this paper, using information theoretic approach, first, we provide a maximum entropy (ME) characterization of some well-known income distributions. Then, we suggest a class of flexible parametric densities which satisfy certain economic constraints and stylized facts of personal income data such as the weak Pareto law and a decline of the income-share elasticities. Our empirical results using the U.S. family income data show that the ME principle provides economically meaningful and a very parsimonious and, at the same time, flexible specification of the income density function.
