    Parallel Title: van der Weide, Roy Poverty and inequality maps for rural Vietnam
    Abstract: The objective of the paper is to update the small area estimates of poverty and inequality for rural Vietnam. The new estimates of province and district level poverty for the year 2006, when combined with estimates available for 1999, allow for examination of how poverty has changed in rural Vietnam over the past seven years. The analysis finds that all provinces across the country experienced a noticeable reduction in rural poverty during the period 1999-2006. Some of the largest reductions in poverty are observed for provinces with poverty rates close to the national average. The poorest provinces have also experienced reductions in poverty, albeit at a more modest pace. Provinces and districts with lower levels of inequality in 2006 have seen above average poverty reductions. The authors consider both expenditure and income based measures of poverty and inequality, and find the results to be very similar

    Parallel Title: van der Weide, Roy Inequality is Bad for Growth of the Poor (But Not for That of the Rich)
    Abstract: The paper assesses the impact of overall inequality, as well as inequality among the poor and among the rich, on the growth rates along various percentiles of the income distribution. The analysis uses micro-census data from U.S. states covering the period from 1960 to 2010. The paper finds evidence that high levels of inequality reduce the income growth of the poor and, if anything, help the growth of the rich. When inequality is deconstructed into bottom and top inequality, the analysis finds that it is mostly top inequality that is holding back growth at the bottom

    Parallel Title: van der Weide, Roy GLS Estimation and Empirical Bayes Prediction for Linear Mixed Models with Heteroskedasticity and Sampling Weights
    Abstract: This note adapts results by Huang and Hidiroglou (2003) on Generalized Least Squares estimation and Empirical Bayes prediction for linear mixed models with sampling weights. The objective is to incorporate these results into the poverty mapping approach put forward by Elbers et al. (2003). The estimators presented here have been implemented in version 2.5 of POVMAP, the custom-made poverty mapping software developed by the World Bank

    Parallel Title: Erscheint auch als van der Weide, Roy Is Inequality Underestimated in Egypt? Evidence from House Prices
    Abstract: Household income surveys often fail to capture top incomes which leads to an underestimation of income inequality. A popular solution is to combine the household survey with data from income tax records, which has been found to result in significant upward corrections of inequality estimates. Unfortunately, tax records are unavailable in many countries, including most of the developing world. In the absence of data from tax records, this study explores the feasibility of using data on house prices to estimate the top tail of the income distribution. In an application to Egypt, where estimates of inequality based on household surveys alone are low by international standards, the study finds strong evidence that inequality is indeed being underestimated by a considerable margin. The Gini index for urban Egypt is found to increase from 36 to 47 after correcting for the missing top tail

    Parallel Title: Douidich, Mohamed Estimating Quarterly Poverty Rates Using Labor Force Surveys
    Abstract: The paper shows how Labor Force Surveys can be used effectively to estimate poverty rates using Household Expenditure Surveys and cross-survey imputation methods. With only two rounds of Household Expenditure Survey data for Morocco (2001 and 2007), the paper estimates quarterly poverty rates for the period 2001-2010 by imputing household expenditures into the Labor Force Surveys. The results are encouraging. The methodology is able to accurately reproduce official poverty statistics by combining current Labor Force Surveys with previous period Household Expenditure Surveys, and vice versa. Although the focus is on head-count poverty, the method can be applied to any welfare indicator that is a function of household income or expenditure, such as the poverty gap or the Gini index of inequality. The newly produced time-series of poverty rates can help researchers and policy makers to: (a) study the determinants of poverty reduction or use poverty as an explanatory factor in cross-section and panel models; (b) forecast poverty rates based on a time-series model fitted to the data; and (c) explore the linkages between labor market conditions and poverty and simulate the effects of policy reforms or economic shocks. This is a promising research agenda that can expand significantly the tool-kit of the welfare economist

    Abstract: This paper quantifies the impact of market access on local GDP in the West Bank, proxied by nighttime lights, using the deployment of road closure obstacles by the Israeli army between 2005 and 2012 as a quasi-natural experiment generating exogenous temporal and spatial variation in accessibility. Minimum travel times between locality pairs are computed using road network and obstacles data supplemented with information on checkpoint traversal times. These are combined with population data to construct a time-varying market access measure for each locality. Market access has a significant and substantial effect on local light emissions. This association is robust to controlling for conflict, and strengthens when market access is instrumented by the number of obstacles located in a radius between 10 and 25km away from the locality

    Parallel Title: Durevall, Dick Importing High Food Prices by Exporting
    Keywords: Reis ; Export ; Reispreis ; Inflationskonvergenz ; Kointegration ; Freihandel ; Wohlfahrtsökonomik ; Laos
    Abstract: This paper shows how a developing country, Lao PDR, imports high glutinous rice prices by exporting its staple food to neighboring countries, Vietnam and Thailand. Lao PDR has extensive export controls on rice, generating a sizable difference between domestic and international prices. Controls are relaxed after good harvests, leading to a surge in exports early in the season and rapidly rising prices later in the year. There is thus a strong case for removal of trade restrictions since they give rise to price spikes, keep the long-term price of glutinous rice low, and thereby hinder increases in income from agriculture. Although this is a case study of Lao PDR, the findings may equally apply to other developing countries that export their staple food

    Parallel Title: Erscheint auch als Marrero, Gustavo A Unequal Opportunity, Unequal Growth
    Abstract: This paper argues that inequality can be both good and bad for growth, depending on what inequality and whose growth. Unequal societies may be holding back one segment of the population while helping another. Similarly, high levels of income inequality may be due to a variety of different factors; some of these may be good while others may be bad for growth. The paper tests this hypothesis by "unpacking" both inequality and growth. Total inequality is decomposed into inequality of opportunity, due to observed factors that are beyond the individual's control, and residual inequality. Growth is measured at different steps of the income ladder to verify whether low, middle, and top income households fare differently in societies with high (low) levels of inequality. In an application to the United States covering 1960 to 2010, the paper finds that inequality of opportunity is particularly bad for growth of the poor. When inequality of opportunity is controlled for, the importance of total income inequality is dramatically reduced. These results are robust to different measures of inequality of opportunity and econometric methods

    Parallel Title: Erscheint auch als Fujii, Tomoki Is Predicted Data a Viable Alternative to Real Data?
    Abstract: It is costly to collect the household- and individual-level data that underlies official estimates of poverty and health. For this reason, developing countries often do not have the budget to update their estimates of poverty and health regularly, even though these estimates are most needed there. One way to reduce the financial burden is to substitute some of the real data with predicted data. An approach referred to as double sampling collects the expensive outcome variable for a sub-sample only while collecting the covariates used for prediction for the full sample. The objective of this study is to determine if this would indeed allow for realizing meaningful reductions in financial costs while preserving statistical precision. The study does this using analytical calculations that allow for considering a wide range of parameter values that are plausible to real applications. The benefits of using double sampling are found to be modest. There are circumstances for which the gains can be more substantial, but the study conjectures that these denote the exceptions rather than the rule. The recommendation is to rely on real data whenever there is a need for new data, and use the prediction estimator to leverage existing data

    Keywords: Gender ; Gender and Development ; Gender Inequality ; Income Growth ; Inequality ; Poverty Reduction ; Race Inequality
    Abstract: Using Integrated Public Use Microdata Series-United States micro-census data from 1960 to 2010, this paper examines whether racial and Gender income disparities beget inequality by differentially impacting the growth prospects of the poor, the middle class, and the rich. Racial and Gender inequality is found to be bad for income growth of the poor, but not for that of the rich. An investigation into the channels of this effect suggests that higher racial and Gender inequality is associated with lower human capital accumulation among the poor and a reduction in the quality of their jobs
