"Theories of poverty traps stand in sharp contrast to the view that anybody can make it through hard work and thrift. However, empirical detection of poverty traps is complicated by the lack of long panels, measurement error, and attrition. This paper shows how dynamic pseudo-panel methods can overcome these difficulties, allowing estimation of non-linear income dynamics and testing for the presence of poverty traps. The paper explicitly allows for individual heterogeneity in income dynamics to account for the possibility that particular groups of individuals may face traps, even if the average individual does not. These methods are used to examine the evidence for a poverty trap in labor earnings, income, and expenditure in Mexico and are compared to panel data estimates from a short rotating panel. The results do find evidence of nonlinearities in household income dynamics and demonstrate large bias in the panel data estimates. Nevertheless, even after allowing for heterogeneity and accounting for measurement error, the paper finds no evidence of the existence of a poverty trap for any group in the sample.

This book takes a new approach on understanding causes of extreme poverty and promising actions to address it. Its focus is on marginality being a root cause of poverty and deprivation. “Marginality” is the position of people on the edge, preventing their access to resources, freedom of choices, and the development of capabilities. The book is research based with original empirical analyses at local, national, and local scales; book contributors are leaders in their fields and have backgrounds in different disciplines. An important message of the book is that economic and ecological approaches and institutional innovations need to be integrated to overcome marginality. The book will be a valuable source for development scholars and students, actors that design public policies, and for social innovators in the private sector and non-governmental organizations.​
Have the lives of the world's poorest, neediest people improved over the past few decades? What policies have lifted some people out of the worst forms of poverty, and what conditions keep others mired within it? The Poorest and Hungry: Assessment, Analyses, and Actions answers such questions, bringing together studies of both what causes and what reduces severe poverty from a diverse group of development specialists. The book focuses on the poorest and hungry in society and identifies areas for action. Stable economic growth; targeted social programs and insurance that invest in and protect nutrition, health, and education; and political and social inclusion of previously marginalized groups emerge as the essential requirements for poverty reduction, and this book's contributors identify strategies for promoting all three. The Poorest and Hungry is an important resource for policymakers, development specialists, and others concerned with helping the world's poorest people.
The Oxford Handbook of Panel Data examines new developments in the theory and applications of panel data. It includes basic topics like non-stationary panels, co-integration in panels, multifactor panel models, panel unit roots, measurement error in panels, incidental parameters and dynamic panels, spatial panels, nonparametric panel data, random coefficients, treatment effects, sample selection, count panel data, limited dependent variable panel models, unbalanced panel models with interactive effects and influential observations in panel data. Contributors to the Handbook explore applications of panel data to a wide range of topics in economics, including health, labor, marketing, trade, productivity, and macro applications in panels. This Handbook is an informative and comprehensive guide for both those who are relatively new to the field and for those wishing to extend their knowledge to the frontier. It is a trusted and definitive source on panel data, having been edited by Professor Badi Baltagi-widely recognized as one of the foremost econometricians in the area of panel data econometrics. Professor Baltagi has successfully recruited an all-star cast of experts for each of the well-chosen topics in the Handbook.
This proceedings volume contains nine selected papers that were presented in the International Symposium in Statistics, 2012 held at Memorial University from July 16 to 18. These nine papers cover three different areas for longitudinal data analysis, four dealing with longitudinal data subject to measurement errors, four on incomplete longitudinal data analysis, and the last one for inferences for longitudinal data subject to outliers. Unlike in the independence setup, the inferences in measurement errors, missing values, and/or outlier models, are not adequately discussed in the longitudinal setup. The papers in the present volume provide details on successes and further challenges in these three areas for longitudinal data analysis. This volume is the first outlet with current research in three important areas in the longitudinal setup. The nine papers presented in three parts clearly reveal the similarities and differences in inference techniques used for three different longitudinal setups. Because the research problems considered in this volume are encountered in many real life studies in biomedical, clinical, epidemiology, socioeconomic, econometrics, and engineering fields, the volume should be useful to the researchers including graduate students in these areas.
Development Economics: Theory and Practice provides students and practitioners with the perspectives and the tools they need to think analytically and critically about the current major economic development issues in the world. Alain de Janvry and Elisabeth Sadoulet identify seven key dimensions of development; growth, poverty, vulnerability, inequality, basic needs, sustainability, and quality of life, and use them to structure the contents of the text. This book gives a historical perspective on the evolution of thought in development. It uses theory and empirical analysis to present readers with a full picture of how development works, how its successes and failures can be assessed, and how alternatives can be introduced. The authors demonstrate how diagnostics, design of programs and policies, and impact evaluation can be used to seek new solutions to the suffering and violence caused by development failures. This text is fully engaged with the most cutting edge research in the field, and equips readers with analytical tools for the impact evaluation of development programs and policies, illustrated with numerous examples. It is underpinned throughout by a wealth of student-friendly features including case studies, quantitative problem sets, end-of-chapter questions, and extensive references. This unique text aims at helping readers learn about development, think analytically about achievements and alternative options, and be prepared to compete on the development job market.
In 1964 President Lyndon Johnson traveled to Kentucky's Martin County to declare war on poverty. The following year he signed the Appalachian Regional Development Act,creating a state-federal partnership to improve the region's economic prospects through better job opportunities, improved human capital, and enhanced transportation. As the focal point of domestic antipoverty efforts, Appalachia took on special symbolic as well as economic importance. Nearly half a century later, what are the results? Appalachian Legacy provides the answers. Led by James P. Ziliak, prominent economists and demographers map out the region's current status. They explore important questions, including how has Appalachia fared since the signing of ARDA in 1965? How does it now compare to the nation as a whole in key categories such as education, employment, and health? Was ARDA an effective place-based policy for ameliorating hardship in a troubled region, or is Appalachia stillmired in a poverty trap? And what lessons can we draw from the Appalachian experience? In addition to providing the reports of important research to help analysts, policymakers, scholars, and regional experts discern what works in fighting poverty, Appalachian Legacy is an important contribution to the economic history of the eastern United States.
Sumner and Mallett review the literature on aid in light of shifts in the aid system and the increasing concentration of the world's poor in middle-income countries. As a consequence, they propose a series of practical, policy relevant options for future development cooperation, with the aim of provoking discussion and informing policy.
