    Bangladesh, a Middle Income Country by 2021 : What Will it Take in Terms of Poverty Reduction?
    (World Bank, Washington, DC, 2014) Gimenez, Lea; Jolliffe, Dean; Sharif, Iffath
    The vision 2021 plan and the associated perspective plan 2010-2021, adopted by the Government of Bangladesh lay out a series of development targets for 2021. Among the core targets identified to monitor the progress toward the vision 2021 objectives is that of attaining a poverty headcount of 14 percent by 2021. The purpose of this paper is to answer the following question: given Bangladesh's performance in poverty reduction over the last decades, can the author expect the proportion of the country's population living in poverty to be 14 percent by 2022? Using data from the last three household income and expenditures survey, we examine changes in poverty rates during 2000-2010, estimate net elasticity of poverty reduction to growth in per-capita expenditure, and then project poverty headcounts into the future. Our poverty projections based on the last three Household Income and Expenditure Surveys (HIES) surveys suggest that Bangladesh will achieve its Millennium Development Goal, or MDG goal of halving its poverty headcount to 28.5 percent by 2015 significantly ahead of schedule. Attaining the vision 2021 poverty target of 14 percent by 2021, however, is less certain as it requires a Gross Domestic Product, or GDP growth of at least 8 percent, or more than 2 percentage points higher than that observed in recent years.

    Food Security and Wheat Prices in Afghanistan : A Distribution-sensitive Analysis of Household-level Impacts
    (World Bank, Washington, DC, 2012-04) D'Souza, Anna; Jolliffe, Dean
    This paper investigates the impact of increases in wheat flour prices on household food security using unique nationally-representative data collected in Afghanistan from 2007 to 2008. It uses a new estimator, the Unconditional Quantile Regression estimator, based on influence functions, to examine the marginal effects of price increases at different locations on the distributions of several food security measures. The estimates reveal that the negative marginal effect of a price increase on food consumption is two and a half times larger for households that can afford to cut the value of food consumption (75th quantile) than for households at the bottom (25th quantile) of the food-consumption distribution. Similarly, households with diets high in calories reduce intake substantially, but those at the bottom of the calorie distribution (25th quantile) make very small changes in intake as a result of the price increases. In contrast, households at the bottom of the dietary diversity distribution make the largest adjustments in the quality of their diets, since such households often live at subsistence levels and cannot make large cuts in caloric intake without suffering serious health consequences. These results provide empirical evidence that when faced with staple-food price increases, food-insecure households sacrifice quality (diversity) in order to protect calories. The large differences in behavioral responses of households that lie at the top and bottom of these distributions suggest that policy analyses relying solely on ordinary least squares estimates may be misleading.

    Rising Food Prices and Coping Strategies : Household-level Evidence from Afghanistan
    (2010-11-01) D'Souza, Anna; Jolliffe, Dean
    This paper investigates the impact of rising wheat prices -- during the 2007/08 global food crisis -- on food security in Afghanistan. Exploiting the temporal stratification of a unique nationally-representative household survey, the analysis finds evidence of large declines in real per capita food consumption and in food security (per capita calorie intake and household dietary diversity) corresponding to the price shocks. The data reveal smaller price elasticities with respect to calories than with respect to food consumption, suggesting that households trade off quality for quantity as they move toward staple foods and away from nutrient-rich foods such as meat and vegetables. In addition, there is increased demand in the face of price increases (Giffen good properties) for wheat products in urban areas. This study improves on country-level simulation studies by providing estimates of actual household wellbeing before and during the height of the global food crisis in one of the world's poorest, most food-insecure countries.
