Focuses on whether and to what extent the pension, the stable source of income leads to change in the labour force attachment of the prime-aged adults in households containing pensioners.

The South African old-age social pension has been much studied by both researchers and policy makers, in part for the larger lessons that might be learned about behavioral responses to cash transfers in developing countries. In this paper, we quantify the labor supply responses of prime-aged individuals to changes in the presence of old-age pensioners in their households, using longitudinal data recently collected in northern KwaZulu-Natal. Our ability to compare households and individuals before and after pension receipt, and pension loss, allows us to control for a host of unobservable household and individual characteristics that may determine labor market behavior. We find that large cash transfers to elderly South Africans lead to increased employment among prime-aged members of their households. Perhaps more importantly, pension receipt influences where this employment takes place. We find large, significant effects on labor migration among prime-aged members upon pension arrival. The pension's impact is attributable both to the increase in household resources it represents, which can be used to stake migrants until they become self-sufficient, and to the presence of pensioners who can care for small children, which allows prime-aged adults to look for work elsewhere.

Cash transfers are a key component of social protection policy in many developing countries. Yet many policymakers are concerned that continued receipt of such transfers may have unintended consequences, such as a reduction in labor supply when household income rises. We study this question by evaluating the impact of Pakistan’s Benazir Income Support Program(BISP), a cash transfer program targeted to poor, married women,on male and female labor supply. The BISP was implemented via a mechanism that reliedon a poverty score cutoff to determine eligibility, allowing for the identification of causal impacts using regression discontinuity. We find no impacts on household labor supply in the aggregate. When we break up estimates by gender, we find littleevidence of a changein female labor supply, strongevidence of increased male labor supply, and no evidence of changes to child labor. Hence, policy makers should not be concerned that BISP transfers negatively affect labor supply among recipients.

In sub-Saharan Africa, older people make up a relatively small fraction of the total population and are supported primarily by family and other kinship networks. They have traditionally been viewed as repositories of information and wisdom, and are critical pillars of the community but as the HIV/AIDS pandemic destroys family systems, the elderly increasingly have to deal with the loss of their own support while absorbing the additional responsibilities of caring for their orphaned grandchildren. Aging in Sub-Saharan Africa explores ways to promote U.S. research interests and to augment the sub-Saharan governments' capacity to address the many challenges posed by population aging. Five major themes are explored in the book such as the need for a basic definition of "older person," the need for national governments to invest more in basic research and the coordination of data collection across countries, and the need for improved dialogue between local researchers and policy makers. This book makes three major recommendations: 1) the development of a research agenda 2) enhancing research opportunity and implementation and 3) the translation of research findings.

Conditional Cash Transfer (CCT) programs aim to reduce poverty by making welfare programs conditional upon the receivers' actions. That is, the government only transfers the money to persons who meet certain criteria. These criteria may include enrolling children into public schools, getting regular check-ups at the doctor's office, receiving vaccinations, or the like. They have been hailed as a way of reducing inequality and helping households break out of a vicious cycle whereby poverty is transmitted from one generation to another. Do these and other claims make sense? Are they supported by the available empirical evidence? This volume seeks to answer these and other related questions. Specifically, it lays out a conceptual framework for thinking about the economic rationale for CCTs; it reviews the very rich evidence that has accumulated on CCTs; it discusses how the conceptual framework and the evidence on impacts should inform the design of CCT programs in practice; and it discusses how CCTs fit in the context of broader social policies. The authors show that there is considerable evidence that CCTs have improved the lives of poor people and argue that conditional cash transfers have been an effective way of redistributing income to the poor. They also recognize that even the best-designed and managed CCT cannot fulfill all of the needs of a comprehensive social protection system. They therefore need to be complemented with other interventions, such as workfare or employment programs, and social pensions.

The Field of Public Economics has been changing rapidly in recent years, and the sixteen chapters contained in this Handbook survey many of the new developments. As a field, Public Economics is defined by its objectives rather than its techniques and much of what is new is the application of modern methods of economic theory and econometrics to problems that have been addressed by economists for over two hundred years. More generally, the discussion of public finance issues also involves elements of political science, finance and philosophy. These connections are evidence in several of the chapters that follow. Public Economics is the positive and normative study of government's effect on the economy. We attempt to explain why government behaves as it does, how its behavior influences the behavior of private firms and households, and what the welfare effects of such changes in behavior are. Following Musgrave (1959) one may imagine three purposes for government intervention in the economy: allocation, when market failure causes the private outcome to be Pareto inefficient, distribution, when the private market outcome leaves some individuals with unacceptably low shares in the fruits of the economy, and stabilization, when the private market outcome leaves some of the economy's resources underutilized. The recent trend in economic research has tended to emphasize the character of stabilization problems as problems of allocation in the labor market. The effects that government intervention can have on the allocation and distribution of an economy's resources are described in terms of efficiency and incidence effects. These are the primary measures used to evaluate the welfare effects of government policy.

International migration, the movement of people across international boundaries to improve economic opportunity, has enormous implications for growth and welfare in both origin and destination countries. An important benefit to developing countries is the receipt of remittances or transfers from income earned by overseas emigrants. Official data show that development countries' remittance receipts totaled 160 billion in 2004, more than twice the size of official aid. This year's edition of Global Economic Prospects focuses on remittances and migration. The bulk of the book covers remittances.

In Let Their People Come, Lant Pritchett discusses five "irresistible forces" of global labor migration, and the "immovable ideas" that form a political backlash against it. Increasing wage gaps, different demographic futures, "everything but labor" globalization, and the continued employment growth in low skilled, labor intensive industries all contribute to the forces compelling labor to migrate across national borders. Pritchett analyzes the fifth irresistible force of "ghosts and zombies," or the rapid and massive shifts in desired populations of countries, and says that this aspect has been neglected in the discussion of global labor mobility. Let Their People Come provides six policy recommendations for unskilled immigration policy that seek to reconcile the irresistible force of migration with the immovable ideas in rich countries that keep this force in check. In clear, accessible prose, this volume explores ways to regulate migration flows so that they are a benefit to both the global North and global South.
