Fiscal Incidence in Ghana

We use methods developed by the Commitment to Equity Institute to assess the effects of government taxation, social spending and indirect subsidies on poverty and inequality in Ghana. We also simulate several policy reforms to assess their distributional consequences. Results show that, although the country has some very progressive taxes and well‐targeted expenditures, the extent of fiscal redistribution is small, but about what one would expect given Ghana's income level and relatively low initial inequality. Results for poverty reduction are less encouraging: were it not for the in‐kind benefits from health and education spending, the overall effect of government spending and taxation would actually increase poverty in Ghana. Eliminating energy subsidies and at the same time reallocating part of the savings to well‐targeted transfer programs could lower the fiscal deficit while reducing inequality and protecting the poor.     

Disentangling the Poverty Effects of Sectoral Output,Prices, and Policies in India

This paper attempts to disentangle the poverty effects of key policy variables that directly affect the poor (namely the government‐led channel of development spending and financing) in both agricultural and non‐agricultural sectors after accounting for the effect of respective sectoral per capita income and prices, using data from India over five decades. The paper emphasizes the sectoral composition of income and prices as mechanisms influencing the level of poverty and establishes empirically that it is the rise in non‐agricultural per capita income that reduces rural poverty via the channel of internal migration, after having controlled for the variation in key components of fiscal spending and monetary/financial policy via the availability of credit. Uneven sectoral growth pattern explains why urban poverty becomes a spill‐over of persistent rural poverty when the agricultural sector shrinks. While checking for robustness, there is evidence that the rise in non‐agricultural income alone may not reduce rural poverty, when measured in terms of rural infant mortality rate as a non‐income indicator of well‐being.     

FGT Old‐Age Poverty Measures and the Mortality Paradox: Theory and Evidence

Income‐differentiated mortality, by reducing the share of poor persons in the population, leads to the “Mortality Paradox”: the worse the survival conditions of the poor are, the lower is the measured poverty. We show that FGT measures (Foster et al ., 1984 ) are, in general, not robust to variations in survival conditions. Then, following Kanbur and Mukherjee ( 2007 ), we propose to adjust FGT poverty measures by extending the income profiles of the prematurely dead, and we identify the condition under which so‐adjusted FGT measures are robust to mortality changes. Finally, we show, on the basis of data from 2007 on old‐age poverty in 11 European economies, that the effect of extending income profiles of the prematurely dead on poverty measurement varies with: (1) the fictitious income assigned to the prematurely dead; (2) the degree of poverty aversion; (3) the shape of the (unadjusted) income distribution; and (4) the strength of the income/mortality relationship.     

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.     

INCOME REDISTRIBUTION IN URBAN CHINA BY SOCIAL SECURITY SYSTEM—AN EMPIRICAL ANALYSIS BASED ON ANNUAL AND LIFETIME INCOME

This study investigates the redistributive effect of social security reform in urban China using the nationally representative urban household surveys of 1995 and 2002. The main findings are as follows. First, public pension is the main income for the elderly in urban China. The majority of people aged 60 and over (72% in 1995 and 82% in 2002) receive a pension. Second, the social security system in urban China has increased the income of low‐income and older age groups and reduced the relative poverty rate. However, the redistributive effect did not offset the expanding income inequality, which resulted in the Gini coefficient of redistributed income in 2002 being higher than that in 1995. Third, during 1995 and 2002, both low‐income and high‐income groups received a positive net benefit from the social security system, but the net benefit increased with income. The Chinese social security system lacks progressivity in contribution, and does not favor the poor in terms of benefits. Fourth, assuming that the reformed policy was applied to public sector employees, the long‐term redistributive effect of the pension system for the working population, calculated using their lifetime income, is larger.

Policy for Poverty Alleviation and Income Redistribution with Quasi-Public Goods

This paper proposes a theoretical framework for a poverty‐alleviation program with quasi‐public goods and presents four main effects. First, this policy succeeds in self‐selection, which identifies low‐productive persons under imperfect information and allows them to receive at least the minimum income. Second, we can observe income redistribution by this scheme without any taxes. Third, the program contributes cost‐effectiveness in many cases. Finally, it makes clear that this policy is suitable, especially in areas where low‐income people are concentrated.     

Relative standing and temporary migration: Empirical evidence from the South Caucasus

This paper empirically investigates the relationship between households’ relative deprivation and the intentions of their members to temporarily migrate abroad in three transition economies of the South Caucasus: Armenia, Azerbaijan and Georgia. To capture respondents’ relative deprivation, we use self‐reported information on respondents’ perception of the relative standing of their household in comparison to those of their neighbors. Controlling for households’ absolute income and other relevant subjective dimensions, we illustrate that households’ relative position vis‐à‐vis their reference groups plays an important role in determining the intentions of their members to migrate abroad. In particular, individuals are more willing to engage in temporary emigration if they perceive themselves to be poorer than the reference group. Our results may have important policy implications. A conjectural suggestion of our empirical exercise is that if migration has to be curbed, reducing absolute poverty alone may not be sufficient. In addition, policy‐makers may need to decrease relative income differentials within the country.     

MEASURING POVERTY USING BOTH INCOME AND WEALTH: A CROSS‐COUNTRY COMPARISON BETWEEN THE U.S. AND SPAIN

We study the correspondence between a household's income and its vulnerability to income shocks in two developed countries: the U.S. and Spain. Vulnerability is measured by the availability of wealth to smooth consumption in a multidimensional approach to poverty, which allows us to identify three groups of households: the twice‐poor group, which includes income‐poor households who lack an adequate stock of wealth; the group of protected‐poor households, which are all those income‐poor families with a buffer stock of wealth they can rely on; and the vulnerable‐non‐poor group, including households above the income‐poverty line that do not hold any stock of wealth. Interestingly, the risk of belonging to these groups changes over the life‐cycle in both countries while the size of the groups differs significantly between Spain and the U.S., although this result is quite sensitive to whether the housing wealth component is included in the wealth measure or not.     

“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.     

The Pro‐Poorness,Growth and Inequality Nexus: Some Findings From a Simulation Study

An income growth pattern is pro‐poor if it reduces a (chosen) measure of poverty by more than if all incomes were growing equiproportionately. Inequality reduction is not sufficient for pro‐poorness. In this paper, we explore the nexus between pro‐poorness, growth, and inequality in some detail using simulations involving the displaced lognormal, Singh–Maddala, and Dagum distributions. For empirically relevant parameter estimates, distributional change preserving the functional form of each of these three‐parameter distributions is often either pro‐poor and inequality reducing, or pro‐rich and inequality exacerbating, but it is also possible for pro‐rich growth to be inequality reducing. There is some capacity for each of these distributions to show trickle effects (weak pro‐richness) along with inequality‐reducing growth, but virtually no possibility of pro‐poorness for growth which increases overall inequality. Implications are considered.     

INEQUALITY AND POVERTY IN JAPAN*

This paper presents a brief survey of inequality and poverty in Japan. It shows empirical evidence on the extent of both inequality in income distribution and of poverty rates; the paper discusses the cause of increases in both these variables, and the implication of such trends. The paper goes on to argue the difference between inequality of opportunity and inequality of outcome and shows some related empirical evidence. Finally, the paper investigates the relationship between economic efficiency and equity, supposed to be in a trade‐off relationship, and presents my personal view of that relationship and policy recommendations.     

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.     

Domestic agricultural value chain development and pro‐poor growth: A computable general equilibrium microsimulation application for the Democratic Republic of Congo

The economy of the Democratic Republic of Congo has gained momentum between 2003 and 2015, with a high annual growth rate of over 6%. However, poverty and employment outcomes were relatively poor, while inequality increased. This study uses a computable general equilibrium (CGE) microsimulation model to study the pro‐poor effect of alternative growth strategy that is likely to strengthen the competitiveness of agro‐food products from the Congo. We experimented with three different scenarios: labor productivity growth, marketing efficiency, and transportation efficiency. The simulations demonstrated that improving the productivity of workers in agro‐food industries has not only produced strong relative pro‐poor effects, but also has the potential to lead to income convergence between rich and poor households. The analysis also revealed the underestimated contribution of agro‐food marketing and transportation efficiency. The major finding is that marketing efficiency favors the middle class. Efficiency gains in the transportation of agro‐food products generate strong pro‐poor effects in absolute and relative terms and are likely to be particularly effective in leading to income convergence. This policy has the potential not only to increase income and employment, but also to provide positive price impacts for both producers and consumers and benefits to all households, particularly low‐income households.     

Sustainability,Optimality, and Development Policy

Considering sustainability a matter of intergenerational welfare equity, this paper examines whether an optimal development path can also be sustainable. It argues that the general “zero‐net‐aggregate‐investment” condition for an optimal development path to be sustainable in the sense of the maximin criterion of intergenerational justice is too demanding to be practical, especially in the context of developing countries. It further argues that while the maximin criterion of sustainability may be appealing to the rich advanced industrial countries, for the poor developing countries it implies equalization of poverty across generations, and as such is too costly a moral obligation to be acceptable. The paper suggests that a compromise development policy that follows the optimal growth approach but adopts certain measures to mitigate both the intergenerational and intragenerational welfare inequalities may be more appropriate for these countries. Some of the principal elements of such a policy are highlighted.     

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.     

POVERTY EQUIVALENT GROWTH RATE

This paper proposes a new type of growth rate, called the “poverty equivalent growth rate” (PEGR), which takes into account both the growth rate in mean income and how the benefits of growth are distributed between the poor and the non‐poor. The proposed measure satisfies a basic requirement that the proportional reduction in poverty is a monotonically increasing function of the PEGR. Thus, maximizing the PEGR implies a maximum reduction in poverty. The paper demonstrates that the magnitude of PEGR determines the pattern of growth: whether growth is pro‐poor in relative or absolute sense or is “poverty reducing” pro‐poor. The pattern of growth has been analyzed for Brazil using the National Household Survey (PNAD) covering the period 1995–2005.     

新型农村社会养老保险政策效果评估——收入、贫困、消费、主观福利和劳动供给

本文使用中国健康与养老追踪调查(CHARLS)数据,采用断点回归和双重差分识别策略,估计了"新农保"对农村老年人收入、贫困、消费、主观福利和劳动供给的影响。研究结果显示,"新农保"养老金收入显著提高了农村老年人的收入水平、减少了贫困的发生、提高了其主观福利,并在一定程度上促进了家庭消费和减少了老年人劳动供给。进一步的研究显示,健康状况较差的老年人受到的政策影响更大更显著,表明"新农保"的政策影响存在异质性。     

Does Medicare benefit the poor?

Measuring the progressivity of age-targeted government programs is difficult because no single data set measures income and benefit use throughout life. Previous research, using zip code as a proxy for lifetime income, has found that Medicare benefits flow primarily to the most economically advantaged groups, and that the financial returns to Medicare are often higher for the rich than the poor. However, our analysis produces the starkly opposed result that Medicare is an extraordinarily progressive public program, in dollar terms or welfare terms. These new results owe themselves to our measurement of socioeconomic status as an individual's education, rather than the geographically aggregated measures of income used by previous research. We argue that individual education has important practical and conceptual advantages over geographically aggregated measures of income. Our results suggest the crucial importance of accurate poverty measurement in evaluating the progressivity of complex government programs like Medicare or Social Security.     

Can Poverty be Alleviated in China?

The 2000s witnessed the third poverty alleviation wave in China. Compared with its predecessors, the third wave distinguished itself by new interventions and redefined standards for the National Poor Counties. This paper evaluates the effectiveness of the new program using a data set consisting of 1,411 of China's western and central counties from 2000 to 2010. It combines the propensity score matching method with the difference‐in‐differences approach, which helps to avoid selection bias and track the policy impact on variables of interest at each time point. It is found that the non‐western local governments tended to manipulate data on income and output growth to maintain the special transfer payments disbursed exclusively to the National Poor Counties. It is also shown that the program failed to improve the infrastructure and sanitary conditions in general.
