A Consistent Poverty Approach to Assessing the Sensitivity of Income Poverty Measures and Trends

This paper examines the sensitivity of estimates of income poverty rates and trends to variations in the poverty line and to whether or not certain households are included or excluded from the sample used to estimate poverty. The approach draws on the concept of consistent poverty, which has been used to identify those with incomes below the poverty line who also experience deprivation. Our approach involves excluding households with incomes below the poverty line if they report zero or negative income or are self‐employed, have expenditure well in excess of their income, have substantial wealth holdings, or if they do not report having experienced financial stress over the past year. The combined impact of all four exclusions is to reduce the half‐median income poverty rate from 9.9 per cent to 5.4 per cent, but also suggests that poverty increased by more over the decade to 2003–04 than the original estimates indicate.     

中国城市中的三种贫困类型

我们课题组在 1 999年进行了一次覆盖六省市的住户调查。本文利用这次调查数据对中国城市贫困的性质和特点进行了考察。通过综合考虑收入标准和消费标准 ,我们把中国城镇贫困分为三种类型 ,即持久性贫困、暂时性性贫困和选择性贫困。在贫困人口中 ,有一大部分是属于选择性贫困 ,即他们的收入高于贫困线而消费低于贫困线。我们对贫困户的消费函数进行了估计 ,其结果显示以下几个因素对贫困状况产生重要的影响 :修匀收入的效应 ;人们防备外部环境不确定性的心理 ;人们为将来投资而进行储蓄的行为 ;家庭对子女教育和医疗服务的特别需要。我们还对三种贫困类型进行了比较分析 ,从中发现预测的金融资产和预测的收入 ,以及教育和医疗的特殊需要都对不同类型的贫困户的消费行为起到重要的影响作用     

LONGITUDINAL MEASURES OF POVERTY: ACCOUNTING FOR INCOME AND ASSETS OVER TIME

This paper uses data from the Survey of Income and Program Participation to estimate durations of poverty spells and to determine whether temporarily poor families have sufficient assets to cover the shortfall of their incomes below poverty—their personal poverty gaps. If poverty is measured using monthly rather than annual income data, four times as many persons enter poverty, but most spells are short: the median duration is between four and six months. More than one-third of all poverty spells are eliminated if financial assets are used to fill poverty gaps, but remaining poverty spells are longer. Separate estimates are made for the elderly and for families with children.     

Three Poverties in Urban China

Radical economic reform and rapid marketization in the late 1990s could be expected to create new poverty and insecurity in Chinese cities. Accordingly, the extent and nature of poverty in urban China is examined by means of a 1999 cross‐section household survey. Three types of poverty—“income and consumption”, “income not consumption” and “consumption not income”—are distinguished. A large proportion of the poor have income above, but consumption below, the poverty line. The estimated consumption function shows the importance of consumption smoothing, of precautionary considerations, of saving for investment opportunities, and of special needs related to the presence of children or sickness. An exercise is conducted to compare the three types of poverty by decomposing the divergence in the consumption of each poverty group from its benchmark consumption. Unpredicted financial assets and income, and differences in special needs, are important in contrasting and explaining the three poverties.     

ESCAPING POVERTY THROUGH WORK: THE PROBLEM OF LOW EARNINGS CAPACITY IN THE UNITED STATES, 1973–88

This paper documents the changes in earnings capacity poverty that occurred between 1973 and 1088. Families are "Earnings Capacity Poor" if they are unable to generate enough income to lift them out of poverty, even if all working-age adults in the family work full-time, year-round. Data from the March 1974 and March 1989 Current Population Surveys indicate that earnings capacity poverty increased more rapidly than official poverty. Much of this increase can be attributed to the rise in earnings capacity poverty among whites, intact families, and family heads with more than a high school diploma. Most alarming, the percentage of children in earnings capacity poor families is considerably higher than it is among persons over eighteen; in 1988, nearly 15 percent of children under six lived in families that could not have escaped poverty even if the adults in their family were working and earning at their full capacity levels.     

COMPARATIVE WELL-BEING OF CHILDREN AND ELDERLY

This paper compares the economic well-being of children and the elderly to each other in the United States and across six industrialized countries. Using the Luxembourg Income Study database, we find that U.S. children–whose economic status is measured by their family income–are generally worse off than U.S. elderly in terms of both poverty and adjusted mean income. Moreover, U.S. children are worse off in terms of higher poverty rates than are the children in any of the other countries studied. The paper presents a variety of explanations for these differences.     

THE SIZE AND DISTRIBUTION OF THE POVERTY GAP IN CANADA: A MICRO ANALYSIS OF VARIATIONS AMONG DEMOGRAPHIC GROUPS

Poverty is a much used term by politicians, economists, sociologists, the media and interest groups. Although there is some common consensus that the word poverty means some type of deprivation, there is a lack of comprehensive measures to quantify this term. Although deprivation can relate to a number of areas such as health and education, the focus in policy development has been aimed at economic deprivation or more specifically, income adequacy. Even in this perspective, the availability of comprehensive measures are limited. The United States is the only major industrial nation that has an official poverty line. Several unofficial poverty lines have been developed in Canada, but the poverty measures have not gone beyond head counts of people who fall below these lines. In an environment where the goal is to further progressive social development constrained by inadequate public resources, the emphasis has been on first directing scarce resources to those "most in need". To get a better perception of economic need, this paper provides a micro analysis of the size and distribution of the poverty gap so that meaningful comparisons can be made between demographic groups. The results of this analysis yield some interesting findings. For example, there are virtually no poor elderly couples and although there are a large number of poor single elderly, their income shortfalls are relatively small and are highly concentrated near the poverty line; the poverty rate among families with children is quite low but their incomes on average fall well below the poverty line and are widely dispersed; and single parents fare badly on all measures.     

生命周期视角下收入主导型多维贫困的识别与成因分析

本文根据我国扶贫政策的目标构建了“收入主导型”的多维贫困识别指标，并对成人和儿童设置了差异化的多维贫困识别标准，以此为基础运用CFPS数据度量了我国多维贫困的程度，最后进一步探究多维贫困产生的原因。有74%的儿童存在至少一个维度上的贫困。儿童的多维贫困程度比成人严重，儿童健康和教育维度贫困率都在20%左右，亟须从生命周期视角下构建精准扶贫政策体系。对多维贫困影响因素的分析结果显示，人力资本因素、家庭负债情况等因素影响显著，折射出教育扶贫、金融扶贫等政策的必要性和紧迫性。     

“When Life Gives You Lemons”: Using Cross-Sectional Surveys to Identify Chronic Poverty in the Absence of Panel Data

At the core of poverty eradication is the need to eliminate that poverty that is persistent over time (chronic poverty). Unfortunately, traditional approaches to identifying chronic poverty require longitudinal data that is rarely available. In its absence, this paper proposes an alternative approach that only requires 1 year of cross-sectional data on monetary and non-monetary poverty. It puts forth two conjectures and contends that the combined profile of a household as both income poor and multidimensionally poor can be used as a proxy of that household being chronically income poor. To explore the viability of this approach, we use a probit model and longitudinal data for three Latin American countries to estimate households’ probabilities of remaining in income poverty based on their past income and multidimensional poverty statuses. We find empirical support for the approach that is significant, consistent across countries, and robust to various controls and periods of analysis.     

Always Poor or Never Poor and Nothing in Between? Duration of Child Poverty in Germany

Abstract. This paper analyses the duration of child poverty in Germany. Observing the entire income history from the individuals' birth to their coming of age at age 18, we are able to analyse dynamics in and out of poverty for the entire population of children, whether they become poor at least once or not. Using duration models, we find that household composition, most importantly single parenthood, and the labour market status as well as level of education of the household head are the main driving forces behind exit from and re‐entry into poverty and thus determine the (long‐term) experience of poverty.     

The welfare of pensioners during economic transition: an analysis of Hungarian survey data1

This paper examines the welfare of pensioners over the early transition period 1987-93 in Hungary. We describe the pension system in detail, and demonstrate the tendency towards compression of the pensioner income distribution towards low income which is induced by the rules and indexation provisions of the pension system. We use the Hungarian Household Budget Surveys to analyse the growth of poverty among the pensioner population and to compare their experience with two other distributionally sensitive groups: households with children and households affected by unemployment.     

The Sins of the Fathers: Intergenerational Income Mobility in China

This paper aims to obtain an accurate estimate of China's intergenerational income mobility and to present evidence on its distributional pattern. Using panel data from the China Health and Nutrition Survey (CHNS) over the period 1989–2009, I find that China is less mobile than most developed countries. Then, I employ five different approaches to investigate the distributional pattern of China's intergenerational mobility across income levels. The results suggest that poor families have relatively high mobility, indicating opportunities for the poor children to escape poverty. Finally, I show that while wealthy fathers are likely to pass on their favorable economic status to their sons, rich sons come from a very wide range of family economic backgrounds.     

A utility-based analysis of the wage subsidy program

Because the poverty line is usually defined in terms of income, two families may be classified as having poverty-level incomes even though their hours of work and, therefore, their utilities may be very different. This paper compares a government income support program that defines the poverty line in terms of utility with several other support programs that define the poverty line in terms of income. Through the use of the wage solution of the indirect utility function, we find the amount of wage subsidy required to raise a subpoverty-line family to the poverty line as defined by the utility function. This subsidy is compared with wage subsidies based on directly observable quantities such as income.     

CHILD POVERTY, INVESTMENT IN CHILDREN AND GENERATIONAL MOBILITY: THE SHORT AND LONG TERM WELLBEING OF CHILDREN IN URBAN CHINA AFTER THE ONE CHILD POLICY

China's One Child Policy (OCP), introduced in 1979, changed fundamentally the nature of both existing and anticipated marriage arrangements and influenced family formation decisions in many dimensions, especially with respect to the number of and investment in children. The policy coincided with the Economic Reforms of 1979 and the trend toward greater urbanization, all of which may have influenced the wellbeing of children. This paper examines the mobility status consequence of children in urban China since the introduction of the OCP and the economic reforms using data drawn from urban household surveys in China. The analysis first makes the comparison between child poverty in Canada, the United Kingdom and urban India, where it was found that both status and trends of child poverty are very different among the countries, with children not being over-represented in the poverty group in urban China. The extent to which the policies influenced investment in children is next examined by studying the way in which the relationship between the educational attainment of children and family characteristics changed within families formed prior to and after 1979. We found that the impact of household income and parental educational attainment increased significantly over time, with a positive gender effect where girls advanced more than boys. Applying new techniques for measuring mobility, we observe the reduction in intergenerational mobility. This phenomenon is found to be particularly prevalent in the lower income quantiles, reinforcing a dynastic notion of poverty.     

Income, Health and Happiness

This article utilises unit record data from the 1989–90 National Health Survey to explore the relationships between low income and perceptions of health and happiness. After describing how the key variables were constructed, attention is focused on the incidence of perceived poor health and unhappiness among those individuals living in income units on either side of a poverty threshold related to the Henderson poverty line. The results reveal that those in poverty generally have poorer health and are less happy than those above the poverty threshold. The observed differences are statistically significant for many income unit types, particularly non-aged single people and couples with children. Attention then turns to exploring how health and happiness vary across the deciles of the income distribution. Again, significant differences are revealed, particularly when more sophisticated distributional measures are employed. Finally, consideration is given to the possibility that the results reflect reverse causality, and that the observed correlations incorporate the role of intervening variables.     

RELATIVE OR ABSOLUTE POVERTY LINES: A NEW APPROACH

When measuring poverty over time analysts must choose the value of the income elasticity of the poverty line, which essentially determines whether an absolute or relative poverty line is being used. The choice of this parameter is ultimately a value judgement, but this paper suggests an approach which has some empirical basis. Borrowing from the life-style and deprivation approach to poverty, various dimensions of poverty and deprivation are identified and the income elasticity of these items is used as the income elasticity of the poverty line. Data from the 1987 and 1994 Irish Household Budget Surveys suggest an upper bound of 0.7 for this parameter. Poverty measures using a number of values of the income elasticity of the poverty line are presented and test statistics are presented to determine whether observed differences in poverty measures are statistically significant.     

COHABITATION AND THE MEASUREMENT OF CHILD POVERTY

We use 1990 U.S. Census of Population data to calculate what poverty rates would have been if cohabitors were treated in the same manner as married couples. We find that the official treatment of cohabiting partners as separate family units overstated the extent of poverty in 1989 among all children by about three percent. Only about 11 percent of the observed rise in child poverty between 1969 and 1989 would be eliminated if the Census Bureau made this change in its definition of the family. We estimate a logistic regression model of the likelihood that poor, cohabiting families with children would be reclassified as non-poor if the cohabitor's income were included in family income.     

Trends in Child Poverty in Australia, 1982 to 1995–96

This study suggests that child poverty in Australia fell by about one-third between 1982 and 1995–96, largely as a result of the very substantial increases in government cash payments to lower income families with children. However, while there were sharp falls in poverty among dependent children, poverty rates among 15 to 18 year-olds who had left the parental home or who were still living at home but not in full-time study increased very sharply. In addition, the after-housing poverty picture did not look so optimistic, apparently due to a compositional shift in the types of families in after-housing poverty.     

WEALTH HOLDINGS AND POVERTY STATUS IN THE U.S.

Families below the poverty line are better off in terms of wealth than income. In 1962, the ratio of mean income between families below and above the poverty line is 0.19 and the ratio of mean wealth is 0.29. The corresponding ratios for 1983 are 0.16 and 0.19. On average, the elderly poor are better off in terms of wealth than the younger poor, particularly relative to their own income. However, the poor have become worse off in terms of wealth between 1962 and 1983, when their real income grew by 6 percent and their real wealth declined by 11 percent. The inclusion of pension and social security wealth in the household portfolio narrows the wealth gap between the poor and non-poor, particularly for families under 65 years of age. Alternative poverty rates are also calculated based on the inclusion of annuity flows from wealth in household income. The reduction in the poverty rate between 1962 and 1983, from 21 to 15 percent on the basis of the official rate, is considerably lower with these alternative definitions.
