Estimating Individual Vulnerability to Poverty with Pseudo-panel Data


Book Description

"Bourguignon, Goh, and Kim present an original method to study individual earning dynamics using repeated cross-sectional data. Because panel data of individuals are seldom available in developing countries, it is difficult to study individual earning dynamics and related issues such as the propensity of earners to fall into poverty or vulnerability to poverty because of changes in earnings. The authors show that under the assumption that individual earning dynamics obey some basic properties and follow a simple stochastic process, the main parameters of this process can be recovered from repeated cross-sectional data. The knowledge of these parameters then permits simulation of the earning dynamics of an individual, and estimate other measures of interest, such as an individual's vulnerability to poverty. The results show that model parameters recovered from pseudo panels approximate reasonably well those estimated directly from a true panel. Moreover, implications of the model, in this case pseudo-panel measures of vulnerability to poverty, reflect closely those based on actual panel data. This paper-- a product of the Office of the Vice President and Chief Economist, Development Economics-- is part of a larger effort in the vice presidency to improve measurement of vulnerability to poverty"-- World Bank web site.

The World Bank Research Program 2004


Book Description

The World Bank's research is intended to address critical issues and problems facing member governments in developing and transition economies. How can the governments of the poorest countries generate enough revenue to provide the education and health services essential to reducing poverty and promoting growth and development? How can poor countries attract investors to build the infrastructure their economies need? How can they develop systems to bring clean water to the 2 billion people without it today? How can they train teachers and bring to class the 115 million children who have not yet received any education? And how can rich countries be persuaded to lower market barriers, helping to reverse the decline in export prices for poor countries that has left them earning less from trade today than in the 1970s? These are the types of questions that are addressed in this edition of 'The World Bank Research Program: Abstracts from Current Studies'. This volume reports on research projects initiated, under way, or completed from July 2003 through June 2004. It covers 151 research projects on several broad development related issues, including agriculture, health, education, environment, infrastructure, investment climate, and more. The abstract for each project describes the questions addressed, the analytic methods used, the findings to date, and policy implications.




Many Dimensions of Poverty


Book Description

With representatives from different disciplines stressing the central importance of freedom in analyzing poverty and emphasizing some important policy issues, this book offers a view of poverty that will orient research in directions previously neglected, and help those in charge of implementing poverty reduction policies.

The Asian ‘Poverty Miracle’


Book Description

Following rapid economic growth in recent decades, Asia and the Pacific experienced an impressive reduction in extreme poverty, but this drop was not uniform and achievements are still incomplete. Vulnerability to natural disasters, the increasing impact of climate change and economic crises should all be taken into account. There is also a need to consider the multidimensional nature of poverty and the non-uniformity of the decrease across different ethnic groups. This book explores the Asian ‘poverty miracle’ and argues for the development and use of an Asia-specific poverty line.




Income Mobility and Welfare


Book Description

This paper develops a framework for the quantitative analysis of individual income dynamics, mobility and welfare. Individual income is assumed to follow a stochastic process with two (unobserved) components, an i.i.d. component representing measurement error or transitory income shocks and an AR(1) component representing persistent changes in income. We use a tractable consumption-saving model with labor income risk and incomplete markets to relate income dynamics to consumption and welfare, and derive analytical expressions for income mobility and welfare as a function of the various parameters of the underlying income process. The empirical application of our framework using data on individual incomes from Mexico provides striking results. Much of measured income mobility is driven by measurement error or transitory income shocks and therefore (almost) welfare-neutral. A smaller part of measured income mobility is due to either welfare-reducing income risk or welfare-enhancing catching-up of low-income individuals with high-income individuals, both of which have economically significant effects on social welfare. Decomposing mobility into its fundamental components is thus seen to be crucial from the standpoint of welfare evaluation.




Handbook of Research on Economic and Social Well-Being


Book Description

The past decade has been characterized by a burgeoning interest in new concepts of individual and social well-being. The impetus for this new research has stemmed from increased demand from policy makers and civil society for measures of progress that go beyond the traditional measures of GDP, as well as improved datasets allowing individuals and households to be tracked over their life course. The aim of this Handbook is to chart these developments and provide extensive surveys of many of the recent themes that have emerged in the research literature. Some of the topics addressed include poverty. relative deprivation and satisfaction, economic insecurity, social exclusion and inequality, income and social polarization, and social fractionalization and diversity. Each topic is first analyzed from a theoretical perspective, followed by detailed empirical discussion.




Social Mobility in Developing Countries


Book Description

Social mobility is the hope of economic development and the mantra of a good society. There are disagreements about what constitutes social mobility, but there is broad agreement that people should have roughly equal chances of success regardless of their economic status at birth. Concerns about rising inequality have engendered a renewed interest in social mobility--especially in the developing world. However, efforts to construct the databases and meet the standards required for conventional analyses of social mobility are at a preliminary stage and need to be complemented by innovative, conceptual, and methodological advances. If forms of mobility have slowed in the West, then we might be entering an age of rigid stratification with defined boundaries between the always-haves and the never-haves-which does not augur well for social stability. Social mobility research is ongoing, with substantive findings in different disciplines--typically with researchers in isolation from each other. A key contribution of this book is the pulling together of the emerging streams of knowledge. Generating policy-relevant knowledge is a principal concern. Three basic questions frame the study of diverse aspects of social mobility in the book. How to assess the extent of social mobility in a given development context when the datasets by conventional measurement techniques are unavailable? How to identify drivers and inhibitors of social mobility in particular developing country contexts? How to acquire the knowledge required to design interventions to raise social mobility, either by increasing upward mobility or by lowering downward mobility?
