POVERTY IN POLAND DURING THE 1990s: ARE THE RESULTS ROBUST?

This study examines the robustness of poverty measures for Poland in the 1990s to employed methods. At least two definitions or techniques of estimation are applied to each of the following components of poverty measures: (1) household well-being; (2) poverty line; (3) equivalence scales; and (4) poverty index. Furthermore, groups at risk of poverty are selected by means of decomposition of the poverty incidence and by estimation of the probit model. Relatively robust conclusions can be reached for trends in absolute poverty incidence, which show an inverted U-shape with rapidly increasing poverty rates in 1993–1995 and declining rates since, but with continued increases in relative poverty. Some robust correlates of high poverty (low education, unemployment, rural residence, large number of children) are also found.     

Poverty Intensity in Australia

Even though poverty indices with axiomatically sound properties have been advocated for several decades, most empirical studies of poverty in Australia and elsewhere continue to use the crude, but easily understood, head-count ratio. The difficulty of interpreting the axiomatically more desirable indices is a major reason why their use has been resisted in applied poverty measurement. This paper demonstrates how the more sophisticated poverty indices can be converted into a form that is readily interpreted as a measure of poverty intensity of a group, relative to the population to which the group belongs. The resulting poverty-intensity index is easy to understand and it retains the axiomatic properties of the poverty index on which it is based. We apply the method to Australian data. Poverty measures reported previously in the literature are converted into measures of poverty intensity and interpreted accordingly. We also calculate and interpret some new measures of poverty and poverty intensity using the 1996–97 Income and Housing Costs Survey, Australia (Australian Bureau of Statistics 1997). It is hoped our procedure will lead to wider use of poverty indices that are theoretically superior to the head-count ratio.     

ASPECTS OF POVERTY IN MALAYSIA

This paper is concerned with the definition and measurement of poverty in Malaysia. A poverty line is estimated after considering both the absolute and relative approaches to the definition. Various indices of poverty are discussed, ranging from the simple "incidence of poverty" measure to others which take account of the "poverty gap". There is a derivation of a new index due to Sen, and alternative normalizations are suggested for it. Estimates of all these measures are presented for Malaysia. Finally, the simple "incidence of poverty" measure, which is decomposable, is adopted to construct a "profile" of the poor in Malaysia.     

Stochastic dominance and decomposable measures of inequality and poverty

In this paper, we characterize some new links between stochastic dominance and the measurement of inequality and poverty. We show that: for second-degree normalized stochastic dominance (NSD), the weighted area between the NSD curve of a distribution and that of the equalized distribution is a decomposable inequality measure; for first-degree and second-degree censored stochastic dominance (CSD), the weighted area between the CSD curve of a distribution and that of the zero-poverty distribution is a decomposable poverty measure. These characterizations provide graphical representations for decomposable inequality and poverty measures in the same manner as Lorenz curve does for the Gini index. The extensions of the links to higher degrees of stochastic dominance are also investigated.     

多维贫困测量及述评简

贫困的测量是各国贫困研究关注的焦点,测量方法随着对贫困概念认识的深化不断变化。如何科学合理地对多维贫困指数进行筛选,成为多维贫困分析和测量的关键。研究发现,非公理标准下的多维贫困指数具有算法简单、操作方便等优点,但缺陷在于各维度间相关性较强且权重分配具有主观性;公理化标准下的多维贫困指数,虽然在指数维度加总问题上存在异议,但满足了大部分公理的要求,且测量结果更稳健。     

ON MEASURING POVERTY

This paper investigates the properties of various measures of poverty and of the "difficulty of alleviation of poverty". It is found that the ranking properties of both kinds of indices can be quite counter-intuitive and that they could be misleading if used for policy evaluation. An alternative index is proposed; it is compared to the other indices and seems to fare rather well. To illustrate, a special reference is made to S. Anand's recent article on poverty in Malaysia.     

Living Decently

One of the reasons why poverty lines became popular at the turn of the century was their promise of a scientific technique that would dispense with moralising about poverty. We argue that a price paid in this quest has been an impoverishment of the richness of the notion of 'a decent life', the moral concept underlying poverty. In addition, poverty lines have in practice been more to do with inequality at the bottom end of the income distribution than with poverty. The purpose of this article is to rehabilitate the measurement of poverty, and to make it credible. We set out our preferred method of poverty measurement, and illustrate it using data from the Australian Standard of Living Study. A feature of our approach is to distinguish clearly between issues of inequality and issues of poverty. Questions such as who is on the bottom of the income distribution, whether this has changed over time, and how income levels of the worst off compare with the mean, are questions of inequality. As such, the answers tell us nothing at all about how the worst off are actually living. To answer that question, we require direct measures of consumption and of social participation. These measures are not as simple, but they provide us with knowledge about poverty that poverty lines have promised, but have not delivered in a credible fashion.     

How Should We Measure Poverty in a Changing World? Methodological Issues and Chinese Case Study

This study asks whether, in a rapidly changing world, the estimated proportion of the world's population with income below US$1 (adjusted according to purchasing power parity) per day is still a good measure of trends in poverty. It argues that strong economic growth in nations such as China implies that the commonly accepted international poverty line definition of one half median national equivalent income is increasingly relevant and that poverty intensity (the normalized deficit or Foster–Greer–Thorbecke (FGT) index of order one) is a better summary index. This index has a convenient graphical representation—the “poverty box”. Using the proposed poverty line and the example of ranking the level of rural poverty in Chinese provinces, the study demonstrates how poverty intensity replicates the poverty rankings of the Sen family of poverty indices and captures most of the information content of higher‐order FGT indices.

Sen measures of poverty in the United States: Cash versus comprehensive incomes in the 1990s

Recently developed statistical inference procedures for the Sen index and its components – the headcount, income gap and Gini index among the poor – are used to test explicit hypotheses concerning aggregate poverty in the United States for the period 1989 to 1997. Changes in Sen measures of poverty are investigated for cash and comprehensive income using the official poverty line and six additional poverty lines drawn using thresholds set at 50, 75, 125, 150, 175 and 200 percent of the official level. The paper also reports on the effects of using comprehensive income on subgroup poverty rates and on the demographic composition of the poor.     

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.     

SEQUENTIAL STOCHASTIC DOMINANCE AND THE ROBUSTNESS OF POVERTY ORDERINGS

When comparing poverty across distributions, an analyst must select a poverty line to identify the poor, an equivalence scale to compare individuals from households of different compositions and sizes, and a poverty index to aggregate individual deprivation into an index of total poverty. A different choice of poverty line, poverty index or equivalence scale can of course reverse an initial poverty ordering. This paper develops easily-checked sequential stochastic dominance conditions that throw light on the robustness of poverty comparisons to these important measurement issues. These general conditions extend well-known results to any order of dominance, to the choice of individual versus family based aggregation, and to the estimation of "critical sets" of measurement assumptions. Our theoretical results are briefly illustrated using data for four countries drawn from the Luxembourg Income Study databases.     

MEASURING PRO-POORNESS: A UNIFYING APPROACH WITH NEW RESULTS

Recent economic literature on pro-poor growth measurement is drawn together, using a common analytical framework which lends itself to some significant extensions. First, a new class of pro-poorness measures is defined, to complement existing classes, with similarities and differences which are fully discussed. Second, all of these measures of pro-poorness can be decomposed across income sources or components of consumption expenditure (depending on the application). This permits the analyst to "unbundle" a pattern of growth, revealing the contributions to overall pro-poorness of constituent parts. Third, all of these pro-poorness measures can be modified to measure pro-poorness at percentiles. An application to consumption expenditures in Indonesia in the 1990s reveals that the poverty reduction achieved remains far below what would have been achieved under distributional neutrality. This can be tracked back to changes in expenditure components.     

THE IMPORTANCE OF CONSECUTIVE SPELLS OF POVERTY: A PATH‐DEPENDENT INDEX OF LONGITUDINAL POVERTY

In this paper we propose a new index of individual poverty in the longitudinal perspective, taking into account the way poverty and non‐poverty spells follow one another along individual life courses. The Poverty Persistence Index (PPI) is based on all the pairwise distances between the waves of poverty. The PPI is normalized and it assigns a higher degree of (longitudinal) poverty to people who experience poverty in consecutive, rather than separated, periods, for whom the distances from the poverty line are larger along time and moreover, when the worst years are consecutive and/or recent. We also propose an aggregate index of persistence in poverty (APPI) in order to measure the distribution of the persistence of poverty in a society, and evaluate at once the diffusion of poverty, its depth, duration, and recentness. The indices are tested in comparison with other measures from the literature both at the individual as well as at the societal level.     

THE USE OF FLOW-OF-FUNDS ACCOUNTS IN MONETARY PLANNING IN YUGOSLAVIA

The increased role of monetary and other financial variables has required the introduction of a quantitative framework for monetary policy planning. This has been found in a planning procedure based on flow-of-funds accounts. The very comprehensive structure of these accounts is relied upon to provide to policy makers with quantitative indications as to policy goals and measures for their implementation, and at the same time, to ensure a consistent incorporation of monetary planning in general economic planning.
There are annual and monthly plans. Annual planning involves two stages. The first is projection of flow-of-funds accounts on the basis of appropriate relationships, historical trends, institutional changes, economic policy targets, etc. The final result of this stage of planning is a projection of the Monetary Sector transactions as residuals, including changes in money supply and in short-term credits as key projections. The second is decomposition of the Monetary Sector account into the Central Bank Sector and the Other Banks Sector, which makes possible a projection of measures for the implementation of projected changes in short-term credits and money supply.
Monthly planning has two objects: first, to check annual projections and, if necessary, to adjust them to actual developments; and second, to introduce seasonal components. Seasonal adjustment is made only for the Monetary Sector, its two subsectors, and credit policy measures. Monthly projections are made every month for three months in advance.     

The Impacts of Unemployment on Alternative Poverty Rates

The analysis uses March Current Population Survey data to estimate state-level cross-section/time-series models of the effects of the unemployment rate on alternative poverty rates. The measures include the official headcount rate, and alternatives based higher thresholds, revised equivalence scales and income defined as inclusive and exclusive of taxes and cash and in-kind transfers. The estimated effects turn critically on the measurement approaches, both for the total sample population and for four population sub-groups. For several alternative poverty rate measures, the unemployment rate has no significant impact on poverty. By contrast, real per-capita median earnings have strong and consistently negative effects on the poverty rates of all groups studied. The findings thus provide important lessons for researchers exploring the links between economic conditions and poverty, and for policy makers developing poverty reduction strategies.     

Multidimensional Poverty and Material Deprivation with Discrete Data

We propose a characterization of a popular index of multidimensional poverty which, as a special case, generates a measure of material deprivation. This index is the weighted sum of the functioning failures. The important feature of the variables that may be relevant for poverty assessments is that they are discrete in nature. Thus, poverty measures based on continuous variables are not suitable in this setting and the assumption of a discrete domain is mandatory. We apply the measure to European Union member states where the concept of material deprivation was initiated and illustrate how its recommendations differ from those obtained from poverty measures based exclusively on income considerations.     

Poverty growth in Scandinavian countries: A Sen multi-decomposition

We show in this paper that the growth rate of the Sen index is multi-decomposable, that is, decomposable simultaneously by subgroups and income sources. The multi-decomposition of the poverty growth yields respectively: the growth rate of the poverty incidence (poverty rate) decomposed by subgroups, the growth rate of the poverty depth (poverty gap ratios) decomposed by sources and subgroups, and the growth rate of inequality decomposed by sources and subgroups. We demonstrate that the multi-decomposition is not unique. It is mainly dependent on poverty lines defined on the space of income sources. An application to Scandinavian countries shows that poverty lines based on non-correlation between the income sources imply serious risks of underestimation of the contribution levels of the different components of the global poverty growth. The main contribution of our paper is to pay particular attention to the poverty growth and its source components in order to avoid underestimation of poverty growth.     

GENDER, POVERTY AND THE INTRA-HOUSEHOLD DISTRIBUTION OF RESOURCES

Most empirical studies of poverty assume an equal sharing of resources between all household members. There is a growing body of research indicating that this assumption is not realistic. This paper explores how the unequal sharing of resources could potentially affect the measurement of poverty. Simulations based on micro-data from two countries (Italy and the U.S.A.) are carried out under the assumption that women "lose" and men and children "gain" because of unequal sharing in the household. Our findings suggest that if there is significant intra-household inequality of this type, as some writers have suggested, then conventional methods of poverty measurement will likely to lead to a serious under-estimate (over-estimate) of the incidence and intensity of female (male) poverty.
