Poverty among ethnic minorities: the transition process,inequality and economic growth

This article investigates the process of reducing poverty in ethnic minority households. Using two recent Vietnam household surveys, we find that ethnic minority households are more likely to be persistently poor and less likely to be persistently non-poor than ethnic majority households. The within-group component generated by the variation in income within each ethnicity group explains more than 90% of the change in total inequality. Income redistribution plays an important role in decreasing the poverty gap and decreasing poverty severity. Different ethnic groups have different poverty patterns, which should be noted when designing policies to alleviate poverty and inequality.     

浅析贫困、经济增长与脱贫时间——基于中国城镇居民调查数据的分析

20世纪90年代以来，经济增长和收入分配不平等对于城镇人口脱贫时间产生了消极影响。研究发现，城镇贫困在1997年达到高峰，然后逐渐缓和；贫困人口的收入增长在初期能使脱贫时间迅速减少，但边际效果是递减的；贫困人口之间的收入分配不平等延长了脱贫时间，如果贫困人口的初始收入增加，则会明显缩短脱贫时间。     

Decomposing poverty changes into vertical and horizontal components

Variations in aggregate poverty indices can be due to differences in average poverty intensity, to changes in the welfare distances between those poor of initially unequal welfare status and/or to emerging disparities in welfare among those poor of initially similar welfare status. This note uses a general cost‐of‐inequality approach that decomposes the total change in poverty into a sum of indices of each of these three components. This decomposition can serve inter alia to integrate horizontal and vertical equity criteria in the poverty alleviation assessment of social and economic programmes. The use of these measures is briefly illustrated using Tunisian data.     

Linkages between poverty and income inequality of urban–rural sector: a time series analysis of India’s urban-based aspirations from 1951 to 1994

This study examines the impact of urban and rural development on poverty and inequality in India before economic reform. The methodology comprises two dimensions. Modern time series methods are used to uncover the dynamic patterns of urban–rural poverty and income inequality. A machine-learning algorithm is used to determine the causal structure among the development indicators. Our results show that reductions in rural poverty appear to be a more effective in reducing both urban and rural poverty, although the costs of achieving these reductions have not been considered.     

MEASURING POVERTY ACCOUNTING FOR TIME

In this paper we make a methodological proposal to measure poverty accounting for time by proposing a new family of intertemporal poverty indexes that aims at reconciling the way poverty is measured in a static and a dynamic framework. Our index is able to consider the duration of the poverty spell and the social preference for equality in well‐being given that, in contrast with others that have been previously proposed, it is sensitive to the level of inequality between individual complete poverty experiences over time. Moreover, other indices in the literature can be interpreted as special cases of our more general measure. An empirical illustration shows the relevance of considering the distribution of poverty experiences among the population in an international analysis.     

Absolute and Relative Deprivation and the Measurement of Poverty

This paper develops the link between poverty and inequality by focussing on a class of poverty indices (some of them well–known) which aggregate normative concerns for absolute and relative deprivation. The indices are distinguished by a parameter value that captures the ethical sensitivity of poverty measurement to "exclusion" or "relative–deprivation" aversion. The indices can be readily used to predict the impact of growth on poverty. An illustration using LIS data finds that the United States show more relative deprivation than Denmark and Belgium whatever the percentiles considered, but that overall deprivation comparisons of the four countries considered will generally depend on the intensity of the ethical concern for relative deprivation. The impact of growth on poverty also depends on the presence of and on the attention granted to concerns over relative deprivation.     

Does microfinance affect income inequality?

This study addresses the question whether participation of the poor in microfinance contributes to reducing a country’s level of income inequality. Using data from 70 developing countries, we show that higher levels of microfinance participation are indeed associated with a reduction of the income gap between rich and poor people. We also show, however, that the effects of microfinance on reducing income inequality are relatively small. The results of this study add to the discussion on the impact of microfinance on poverty by showing that, although access to microfinance does seem to improve the relative income position of the poor, this improvement is modest, which is probably because the use of microfinance is generally small as compared to the size of the economy of the countries in our sample. Microfinance should, therefore, not be seen as a panacea for bringing down income inequality in a significant way.     

Missing poor and income mobility

Higher mortality among the poor prevents standard poverty measures from quantifying the actual extent of old-age poverty. Whereas existing attempts to deal with the ”missing poor” problem assume the absence of income mobility and assign to the prematurely dead a fictitious income equal to the last income enjoyed, this paper relaxes that assumption in order to study the impact of income mobility on the size of the missing poor bias. We use data on poverty above age 60 in 12 countries from the EU-SILC database, and we compare standard poverty rates with the hypothetical poverty rates that would have prevailed if (i) all individuals, whatever their income, had enjoyed the same survival conditions, and if (ii) all individuals within the same income class had been subject to the same income mobility process. Taking income mobility into account has unequal effects on corrected poverty measures across countries, and, hence, affects international comparisons in terms of old-age poverty.     

Economic transition and the distributions of income and wealth

This paper relies on a model of wealth distribution dynamics and occupational choice to investigate the distributional consequences of policies and developments associated with transition from central planning to a market system. The model suggests that even an efficient privatization designed to be egalitarian may lead to increases in inequality (and possibly poverty), both during transition and in the new steady-state. Creation of new markets in services also supplied by the public sector may also contribute to an increase in inequality, as can labour market reforms that lead to a decompression of the earnings structure and to greater flexibility in employment. The results underline the importance of retaining government provision of basic public goods and services; of removing barriers that prevent the participation of the poor in the new private sector; and of ensuring that suitable safety nets are in place.     

LOCAL DISTRIBUTIONAL EFFECTS OF GOVERNMENT CASH TRANSFERS IN CHILE

Despite rapid economic growth and poverty reduction, inequality in Chile has remained high and remarkably constant over the last 20 years, prompting academic and public interest in the subject. Due to data limitations, however, research on inequality in Chile has concentrated on the national and regional levels. The impact of cash subsidies to poor households on local inequality is thus not well understood. Using poverty‐mapping methods to asses this impact, we find heterogeneity in the effectiveness of regional and municipal governments in reducing inequality via poverty‐reduction transfers, suggesting that alternative targeting regimes may complement current practice in aiding the poor.     

Short-term trends in China’s income inequality and poverty: evidence from a longitudinal household survey

In the past three decades, income inequality in China has increased rapidly relative to both China’s own past and other countries at similar levels of economic development. Using recent longitudinal data from the China Family Panel Studies (CFPS), this article examines changes in income inequality and poverty prevalence between 2010 and 2012. Surprisingly, we find a modest decline in income inequality as measured by the Gini coefficients in the CFPS data. The urban–rural gap narrowed, with rural families enjoying faster income growth than urban families enjoyed. Income growth was greater for middle-income families than for families with either high or low incomes in 2010. By all measures, poverty was greatly reduced between 2010 and 2012. Two-thirds of families that had been poor in 2010 escaped poverty by 2012.     

Consumer Debt and the Measurement of Poverty and Inequality in the US∗

This paper argues that interest on consumer debt must be taken into account when measuring poverty and inequality. These interest payments cannot be used to support household living standards. This makes middle- and low-income households worse off. Recent increases in consumer debt means that this deterioration in living standards is not captured by conventional government statistics. Using the Survey of Consumer Finances, we make estimates of poverty and inequality that take into account rising interest payments on consumer debt and discuss some of the implications of these estimates.     

A NEW MULTIPLICATIVE DECOMPOSITION FOR THE FOSTER–GREER–THORBECKE POVERTY INDICES

This paper shows that Foster–Greer–Thorbecke poverty indices can be written as the product of components summarizing the incidence, intensity and inequality dimensions of poverty and provides an empirical illustration of the decomposition using Spanish household budget surveys data.

Unfair inequality and growth*

Fighting against economic inequality is one fundamental social goal in the agendas of most governments. However, recent studies highlight that people actually prefer unequal societies, as they accept inequality generated by an individual's effort and wish to reduce only unfair inequality (generated by factors beyond an individual's control). This distinction might help to explain the fundamental unsolved question about whether inequality is good or bad for growth: unfair inequality (UI) could be growth-deterring, while fair inequality (FI) might be growth-enhancing. We derive a reduced-form growth equation from a stylized overlapping-generations model with human capital that includes FI, UI, and poverty. Then, using an instrumental variable approach, we show for alternative samples and inequality measures at the worldwide level that the estimated coefficient associated with UI is always negative, while the coefficient of total inequality increases when UI is included in the regression. Moreover, we find that poverty mediates this relationship because the higher the poverty rate, the smaller the impact of either type of inequality on growth.     

The Covariance Structure of East and West German Incomes and its Implications for the Persistence of Poverty and Inequality

Abstract. Based on data from the German Socio-Economic Panel (GSOEP), this paper analyzes the dynamics of equivalent income in East and West Germany in the years following reunification. Special emphasis is given to the separation of permanent and transitory components, the persistence of transitory shocks and their implications for the persistence of poverty and inequality. The results suggest that in West Germany, between 52 and 69 per cent of cross-sectional income inequality was permanent, and that poor individuals stayed in poverty for two years on average. In East Germany, the share of the permanent component in overall income inequality rose continuously from 20 per cent in 1990 to 72 per cent in 1998, reaching a level near the one that prevailed in West Germany during the same period. The rising importance of time-invariant components in East German incomes was also reflected in expected poverty durations which slightly increased from 1.47 years in 1990 to 1.67 years in 1998.     

National pro-poor spending programmes and their effect on income inequality and poverty: Evidence from Vietnam

This article examines the causal effects of the national (pro-poor) targeted programmes (NTPs) on both poverty incidence and inequality in Vietnam over the period 2002–2010. While the links between NTPs and poverty alleviation and income inequality have previously been analysed independently, this study is the first to offer a comprehensive analysis of NTPs expenditure on poverty and inequality simultaneously. Applying the system generalized method of moments estimator to a panel of Vietnamese regional data, we are unable to establish that NTPs have significantly mitigated poverty incidence. However, we estimate that NTPs have significantly increased inequality. We offer possible explanations why the NTPs have resulted in these unintended outcomes and discuss potential policies which can reduce both poverty and inequality.     

Meeting the Social Policy Challenges Facing Korea

Korea faces the fastest population aging among Organisation for Economic Cooperation and Development countries and increasing levels of income inequality and relative poverty. While economic growth will help address these challenges, growth alone is not sufficient, making it necessary to introduce policies to promote social cohesion. First, the National Pension Scheme and the National Health Insurance need to be improved. Second, Korea should develop well‐targeted social programs and expand the earned income tax credit. Third, it is important to reduce labor market dualism, a major cause of inequality due to the large wage gap between regular and non‐regular workers. Fourth, education reform is needed to lower the financial burden of tertiary education, reduce the heavy reliance on hagwon and increase spending on preprimary education. At the same time, it is essential to maintain a sound fiscal position by increasing tax revenues, primarily through indirect taxes and environmental taxes, to cover rising social spending.     

Channels of redistribution: Inequality and poverty in the Russian transition

Contrary to popular perception, Russia entered the transition with significant inequality. Using the large Russian Longitudinal Monitoring Survey dataset, we demonstrate that inequality has subsequently risen yet further and by end-1996 was roughly comparable to inequality in Mexico, Colombia or Malaysia. Driving this increase has been not only wealth transfers through privatization but also changes in government expenditure and a sharp growth in earnings dispersion. There has been a large, associated shift in the structure of income. The paper also looks at the incidence and depth of poverty over the period 1992-96. At the start of transition, roughly half the population of households fell below the poverty line. While this has subsequently declined, at end-1996 nearly 40 per cent of households were below the poverty line and a substantial stratum of households were locked in chronic poverty.
