    Purchasing Power Parity Exchange Rates for the Global Poor
    (2011-04) Deaton, Angus; Dupriez, Olivier
    The global poverty count uses a common global poverty line, often referred to as the dollar-a-day line, currently $1.25 at 2005 international prices, whose construction and application depends on purchasing power parity (PPP) exchange rates for consumption. The price indexes that underlie the PPPs used for this purpose are constructed for purposes of national income accounting, using weights that represent patterns of aggregate consumption, not the consumption patterns of the global poor. We use household surveys from 62 developing countries to calculate global poverty-weighted PPPs and to calculate global poverty lines and new global poverty counts.

    Child Mortality in Rural India
    (2011) van der Klaauw, Bas; Wang, Limin
    This paper focuses on infant and child mortality in rural areas of India. We construct a flexible duration model, which allows for frailty at multiple levels and interactions between the child's age and individual, socioeconomic, and environmental characteristics. The model is estimated using the Indian National Family and Health Survey 1998/1999. The estimation results show that socioeconomic and environmental characteristics have significantly different impacts on mortality rates at different ages. These are particularly important immediately after birth. The parameter estimates indicate that child mortality can be reduced substantially, particularly by improving the education of women, providing safe water, and reducing indoor air pollution caused by dirty cooking fuels. Finally, we still found substantial differences in mortality rates between states, which are associated with differences in schooling expenditures, female immunization, and poverty rates.

    The Impact of the Global Financial Crisis on Off-Farm Employment and Earnings in Rural China
    (2011) Huang, Jikun; Zhi, Huayong; Huang, Zhurong; Rozelle, Scott; Giles, John
    This paper examines the effect of the financial crisis on off-farm employment of China's rural labor force. Using a national representative dataset, we find that there was a large impact. By April 2009 off-farm employment reached 6.8% of the rural labor force. Monthly earnings also declined. However, while we estimate that 49 million were laid-off between October 2008 and April 2009, half of them were re-hired in off-farm work by April 2009. By August 2009, less than 2% of the rural labor force was unemployed due to the crisis. The robust recovery appears to have helped avoid instability.

    Was Vietnam's Economic Growth in the 1990s Pro-poor? An Analysis of Panel Data from Vietnam
    (2011) Glewwe, Paul; Dang, Hai-Anh Hoang
    International aid agencies and almost all economists agree that economic growth is necessary for reducing poverty, yet some economists question whether it is sufficient for poverty reduction. Vietnam enjoyed rapid economic growth in the 1990s, but a modest increase in inequality during that decade raises the possibility that the poor in Vietnam benefited little from that growth. This article examines the extent to which Vietnam's economic growth has been "pro-poor," giving particular attention to two issues. The first is the appropriate comparison group. When comparing the poorest x% of the population at two points in time, should the poorest x% in the first time period be compared to the poorest x% in the second time period (some of whom were not the poorest x% in the first time period) or to the same people in the second time period (some of whom are no longer among the poorest x%)? The second is measurement error. Estimates of growth among the poorest x% of the population are likely to be biased if income or expenditure is measured with error. Household survey data show that Vietnam's growth has been relatively equally shared across poor and nonpoor groups. Indeed, comparisons of the same people over time indicate that per capita expenditures of the poor increased much more rapidly than those of the nonpoor, although failure to correct for measurement error exaggerates this result.

    Cash Transfers, Children and the Crisis : Protecting Current and Future Investments
    (2011) Fiszbein, Ariel; Srinivasan, Santhosh
    In a mix of responses to the food, fuel, and financial crises of 2008-9, some developing countries have introduced new safety-net programmes, while others have modified and/or expanded existing ones. Many have introduced conditional cash transfers (CCTs) in recent years, and these have been used as an important starting point for a response. This article aims to describe these various experiences with CCTs, to distil lessons about their effectiveness as crisis-response programmes for households with children, to identify design features that can facilitate their ability to respond to transient poverty shocks, and to assess how they can complement other safety-net programmes.

    Gender Implications of Biofuels Expansion in Africa : The Case of Mozambique
    (2011) Arndt, Channing; Benfica, Rui; Thurlow, James
    We use a gendered dynamic CGE model to assess the implications of biofuels expansion in a low-income, land-abundant setting. Mozambique is chosen as a representative case. We compare scenarios with different gender employment intensities in producing jatropha feedstock for biodiesel. Under all scenarios, biofuels investments accelerate GDP growth and reduce poverty. However, a stronger trade-off between biofuels and food availability emerges when female labor is used intensively, as women are drawn away from food production. A skills-shortage among female workers also limits poverty reduction. Policy simulations indicate that only modest improvements in women's education and food crop yields are needed to address food security concerns and ensure broader-based benefits from biofuels investments.

    The Long Term Educational Cost of War: Evidence from Landmine Contamination in Cambodia
    (2011) Merrouche, Ouarda
    The economic impact of war may be visible in the long run and particularly through its impact on human capital. This paper uses unique district level data on landmine contamination intensity in Cambodia combined with survey data on individuals to evaluate the long-run impact of Cambodia's 30 years of war (1970-1998) on education levels and earnings. These effects are identified using difference-in-differences (DD) and instrumental variables (IV) estimators. In the DD framework I exploit two sources of variation in an individual's exposure to the conflict: age in 1970 and landmine contamination intensity in the district of residence. The IV specification uses the distance to the Thai border as an exogenous source of variation in landmine contamination intensity. The most conservative result indicates that individuals who were too young to have attended school before the start of the war received on average 0.5 less years of education. And, immediately after the war there was no visible effect on earnings. The effects are therefore overall weak. I argue that the destruction of physical capital may be what contributes to drive down the returns to education in Cambodia post-war. The estimates reported may be very conservative due to both error in our measure of conflict intensity and possible selection bias in the placement of prosperous regions.

    Assessing the Impact of Migration on Food and Nutrition Security
    (2011) Zezza, Alberto; Carletto, Calogero; Davis, Benjamin; Winters, Paul
    Migration has become a key component in the livelihood strategies of an increasing number of households across the developing world and remittances have expanded dramatically in the last decade. This has come at a time when an increased emphasis has been placed on reducing malnutrition to achieve Millennium Development Goal (MDG) targets. While this is the case, there has been little attention on the interface between migration and nutrition even though migration can influence nutrition through a number of channels. The objective of this special issue is to present state-of-the-art analyses of the link between migration and nutrition in developing countries. In this paper, an overview of the conceptual and empirical issues in identifying the link between migration and nutrition are considered. Further, the results from seven country case studies are synthesized and policy implications are drawn.

    Would Freeing Up World Trade Reduce Poverty and Inequality? The Vexed Role of Agricultural Distortions
    (2011) Anderson, Kym; Martin, Will
    Trade policy reforms in recent decades have sharply reduced the distortions that were harming agriculture in developing countries, yet global trade in farm products continues to be far more distorted than trade in non-farm goods. Those distortions reduce some forms of poverty and inequality but worsen others, so the net effects are unclear without empirical modelling. This article summarises a series of new economy-wide global and national empirical studies that focus on the net effects of the remaining distortions to world merchandise trade on poverty and inequality globally and in various developing countries. The global Linkage model results suggest that removing those remaining distortions would reduce international inequality, largely by boosting net farm incomes and raising real wages for unskilled workers in developing countries, and would reduce the number of poor people worldwide by 3 per cent. The analysis based on the Global Trade Analysis Project model for a sample of 15 countries, and nine stand-alone national case studies, all point to larger reductions in poverty, especially if only the non-poor are subjected to increased income taxation to compensate for the loss of trade tax revenue.

    Towards a Unified Scheme for Environmental and Social Protection: Learning from PES and CCT Experiences in Developing Countries
    (2011) Rodriguez, Luis C.; Pascual, Unai; Muradian, Roldan; Pazmino, Nathalie; Whitten, Stuart
    Environmental protection and poverty alleviation in the developing world are usually heralded as joint objectives. However, these two goals are often associated with different sectoral policy instruments. While so-called payments for environmental services (PES) are increasingly being promoted for environmental protection, poverty alleviation is increasingly addressed by conditional cash transfers (CCT) program. These instruments although aimed to achieve distinct objectives have a number of similarities and challenges in their design and implementation phases. This paper elaborates on these similarities and develops a unifying generic framework that is used to discuss the extent to which both approaches could be unified.
