Available in PDF, EPUB and Kindle. Book excerpt: Although poverty lines are widely used as deflators for intergroup welfare comparisons, their internal consistency is rarely given close scrutiny. A priori considerations suggest that commonly used methods cannot be relied on to yield poverty lines that are consistent in terms of utility, or for capabilities more generally. The theory of revealed preference offers testable implications of utility consistency for "poverty baskets" under homogeneous preferences. A case study of Russia's official poverty lines reveals numerous violations of revealed preference criteria--violations that are not solely attributable to heterogeneity in preferences associated with climatic differences. This paper--a product of the Poverty Team, Development Research Group--is part of a larger effort in the group to improve poverty measurement methodology.

This book was released on 2008 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The theory and evidence supporting a relativist approach to poverty measurement are critically reviewed. Various sources of welfare interdependence are identified, including the idea of "relative deprivation" as well other (positive and negative) welfare effects for poor people of belonging to a better-off group. An economic model combines informal risk sharing with the idea of a "positional good," and conditions are derived in which the relative deprivation effect dominates, implying a relative poverty measure. The paper then reviews the problems encountered in testing for welfare effects of relative deprivation and discusses the implications of micro evidence from Malawi. The results are consistent with the emphasis given to absolute level of living in development policy discussions. However, relative deprivation is still evident in the data from this poor but unequal country, and it is likely to become a more important factor as the country develops.

Book excerpt: In theory, a poverty line can be defined as the cost of a common (inter-personally comparable) utility level across a population. But how can one know if this holds in practice? For groups sharing common consumption needs but facing different prices, the theory of revealed preference can be used to derive testable implications of utility consistency knowing only the "poverty bundles" and their prices. Heterogeneity in needs calls for extra information. We argue that subjective welfare data offer a credible means of testing utility consistency across different needs groups. A case study of Russia's official poverty lines shows how revealed preference tests can be used in conjunction with qualitative information on needs heterogeneity. The results lead us to question the utility consistency of Russia's official poverty lines.
Download or read book Estimating Utility Consistent Poverty Lines with Applications to Egypt and Mozambique written by Channing Arndt and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental premise of absolute poverty lines is that they represent the same level of utility through time and space. Disturbingly, a series of recent studies in middle- and low-income economies show that even carefully derived poverty lines rarely satisfy this premise. This article proposes an information-theoretic approach to estimating cost-of-basic-needs (CBN) poverty lines that are utility consistent. Applications to date illustrate that utility-consistent poverty measurements derived from the proposed approach and those derived from current CBN best practices often differ substantially, with the current approach tending to systematically overestimate (underestimate) poverty in urban (rural) zones.

Detailed analyses of poverty and wellbeing in developing countries, based on household surveys, have been ongoing for more than three decades. The large majority of developing countries now regularly conduct a variety of household surveys, and the information base in developing countries with respect to poverty and wellbeing has improved dramatically. Nevertheless, appropriate measurement of poverty remains complex and controversial. This is particularly true in developing countries where (i) the stakes with respect to poverty reduction are high; (ii) the determinants of living standards are often volatile; and (iii) related information bases, while much improved, are often characterized by significant non-sample error. It also remains, to a surprisingly high degree, an activity undertaken by technical assistance personnel and consultants based in developed countries. This book seeks to enhance the transparency, replicability, and comparability of existing practice. In so doing, it also aims to significantly lower the barriers to entry to the conduct of rigorous poverty measurement and increase the participation of analysts from developing countries in their own poverty assessments. The book focuses on two domains: the measurement of absolute consumption poverty and a first order dominance approach to multidimensional welfare analysis. In each domain, it provides a series of flexible computer codes designed to facilitate analysis by allowing the analyst to start from a flexible and known base. The book volume covers the theoretical grounding for the code streams provided, a chapter on 'estimation in practice', a series of 11 case studies where the code streams are operationalized, as well as a synthesis, an extension to inequality, and a look forward.

Available in PDF, EPUB and Kindle. Book excerpt: The "Cost of Basic Needs" (CBN) approach to drawing consumption-based poverty lines is widely applied and lays credible claim to being the best practice for estimating poverty measures. Unfortunately, a growing mass of evidence indicates that poverty estimates obtained under the CBN approach are often demonstrably utility inconsistent. Here, we introduce an information theoretic approach for estimating utility-consistent poverty lines. An example of the approach is provided for the case of Mozambique. The approach represents a powerful addition to the poverty analyst's tool kit and enhances the attractiveness of the CBN approach for practical poverty measurement problems.
Download or read book Nutrition as a basic need A new method for utility consistent and nutritionally adequate food poverty lines written by Mahrt, Kristi and published by Intl Food Policy Res Inst. This book was released on 2022-05-06 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most countries and globally, malnutrition rates exceed poverty rates. The World Bank estimates that about 9 percent (689 million) of the global population is poor, yet an estimated 25 percent (2 billion people) suffer from micronutrient deficiencies. Such a discrepancy begs the question: Do standard poverty metrics poorly reflect nutritional needs? The most prevalent methodology for measuring poverty in low- and middle-income countries – the cost of basic needs approach – estimates food baskets that satisfy a dietary energy standard while reflecting consumption patterns of poor households. However, poor households typically consume monotonous diets characterized by large quantities of calorically cheap staple foods that are poor sources of nutrients. This reality creates a circular logic whereby the cost of basic nutritional needs is estimated from populations who are consuming nutritionally inadequate diets. We argue that a healthy diet is a basic need and that the standard used to calculate cost of basic needs food poverty lines should be expanded to satisfy nutritional dietary recommendations, while continuing to reflect context-specific dietary patterns. We develop an approach to estimate food poverty lines that satisfies the food group proportionality associated with healthy diet recommendations while also adhering to observed within-food group consumption patterns of poor households. Furthermore, we address the limitation of estimating a single national food basket – which fails to capture variation in local consumption patterns driven by preferences, availability, and relative prices – by estimating utility-consistent regional poverty lines. We demonstrate the approach using data from Myanmar. Energy-based poverty lines significantly underestimate the cost of acquiring a healthy diet, are severely deficient in multiple micronutrients, and therefore result in a drastic underestimate of the rate of poverty based on a healthy diet standard. The resulting higher cost of basic needs also has important implications for inclusive economic growth strategies and nutrition-sensitive food policies and social protection.

Download or read book Consistent Poverty Comparisons and Inference written by Channing Arndt and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Building upon the cost of basic needs (CBN) approach, an integrated approach to making consumption-based poverty comparisons is presented. This approach contains two principal modifications to the standard CBN approach. The first permits the development of multiple poverty bundles that are utility consistent. The second recognizes that the poverty line itself is a random variable whose variation influences the degree of confidence in poverty measures. We illustrate the empirical importance of these two methodological changes for the case of Mozambique. With utility consistency imposed, estimated poverty rates tend to be systematically higher in rural areas and lower in urban areas. We also find that the true confidence intervals on the poverty estimates-those incorporating poverty line variance-tend to be considerably larger than those that ignore poverty line variance. Finally, we show that these two methodological changes interact. Specifically, we find that imposing utility consistency on poverty bundles tends to tighten confidence intervals, sometimes dramatically, on provincial poverty estimates. We conclude that this revised approach represents an important advance in poverty analysis. The revised approach is straightforward and directly applicable in empirical work.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of essays honors a remarkable man and his work. Erik Thorbecke has made significant contributions to the microeconomic and the macroeconomic analysis of poverty, inequality and development, ranging from theory to empirics and policy. The essays in this volume display the same range. As a collection they make the fundamental point that deep understanding of these phenomena requires both the micro and the macro perspectives together, utilizing the strengths of each but also the special insights that come when the two are linked together. After an overview section which contains the introductory chapter and a chapter examining the historical roots of Erik Thorbecke's motivations, the essays in this volume are grouped into four parts, each part identifying a major strand of Erik's work—Measurement of Poverty and Inequality, Micro Behavior and Market Failure, SAMs and CGEs, and Institutions and Development. The range of topics covered in the essays, written by leading authorities in their own areas, highlight the extraordinary depth and breadth of Erik Thorbecke's influence in research and policy on poverty, inequality and development. Acknowledgements These papers were presented at a conference in honor of Erik Thorbecke held at Cornell University on October 10-11, 2003. The conference was supported by the funds of the H. E. Babcock Chair in Food, Nutrition and Public Policy, and the T. H. Lee Chair in World Affairs at Cornell University.

Available in PDF, EPUB and Kindle. Book excerpt: Issues concerning economic inequality and poverty have become increasingly central to public debate over the past fifty years. The literature on measuring economic inequality and poverty has vastly expanded, developing many new methods, but also has generated many controversies. Economic Inequality and Poverty provides a systematic treatment of the development of inequality and poverty, focusing on how income inequality and poverty measurements have evolved in recent decades, and shows how to resolve some of the methodological and factual conflicts that have arisen. The book's primary focus is on the analysis of the relationships between individuals' or households' distributions of economic variables. These relationships are crucial in understanding many economic phenomena. Kakwani and Son employ household surveys to illustrate the application of their framework, showing how it can help in drawing evidence-based policy conclusions.

This book was released on 2022-08-04 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Papua New Guinea continues to encourage a policy focus on food and nutrition security. The PNG National Nutrition Policy (2016-2026) and Nutrition Strategic Action Plan (2018-2022) (NSAP) set a path to improve coordination, secure sufficient funding, and improve technical capacity of nutrition-focused pro gram implementation. As policy prioritizes improved nutrition outcomes, it is important to understand the cost that households face of securing a higher level of nutrition. Ensuring a healthy diet that meets nutrition standards is relatively expensive in PNG. The analysis presented in this paper, which uses detailed household food and non-food consumption data suggests that 4/5 of households in the survey sample live below the healthy diet poverty line (which sets a calorie threshold and defines healthy diet nutrition targets). That is, these households do not have the income available (or do not consume sufficient food and non-food goods) to meet their basic needs which includes securing a nutritious diet that meets food based die tary guidelines.
Download or read book Growth and Poverty in Sub Saharan Africa written by Channing Arndt and published by Oxford University Press. This book was released on 2016 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the economic growth renaissance in sub-Saharan Africa is widely recognized, much less is known about progress in living conditions. This book comprehensively evaluates trends in living conditions in 16 major sub-Saharan African countries, corresponding to nearly 75% of the total population. A striking diversity of experience emerges. While monetary indicators improved in many countries, others are yet to succeed in channeling the benefits of economic growth into the pockets of the poor. Some countries experienced little economic growth, and saw little material progress for the poor. At the same time, the large majority of countries have made impressive progress in key non-monetary indicators of wellbeing. Overall, the African growth renaissance earns two cheers, but not three. While gains in macroeconomic and political stability are real, they are also fragile. Growth on a per capita basis is much better than in the 1980s and 1990s, yet not rapid compared with other developing regions. Importantly from a pan-African perspective, key economies-particularly Kenya, Nigeria, and South Africa-are not among the better performers. Looking forward, realistic expectations are required. The development process is, almost always, a long hard slog. Nevertheless, real and durable factors appear to be at play on the sub-continent with positive implications for growth and poverty reduction in future.
