Global poverty counts (millions) 330 3 $aWe analyze the performance of kernel density methods applied to grouped data to estimate poverty (as applied in Sala-i-Martin, 2006, QJE). Using Monte Carlo simulations and household surveys, we find that the technique gives rise to biases in poverty estimates, the sign and magnitude of which vary with the bandwidth, the kernel, the number of datapoints, and across poverty lines. Depending on the chosen bandwidth, the $1/day poverty rate in 2000 varies by a factor of 1.8, while the $2/day headcount in 2000 varies by 287 million people. Our findings challenge the validity and robustness of poverty estimates derived through kernel density estimation on grouped data. 410 0$aIMF Working Papers; Working Paper ;$vNo. 2008/183 606 $aPoverty$xMeasurement 606 $aIncome distribution$xEconometric models 606 $aKernel functions 606 $aEconometrics$2imf 606 $aMacroeconomics$2imf 606 $aDemography$2imf 606 $aPoverty and Homelessness$2imf 606 $aWelfare, Well-Being, and Poverty: General$2imf 606 $aPersonal Income, Wealth, and Their Distributions$2imf 606 $aAggregate Factor Income Distribution$2imf 606 $aDemographic Economics: General$2imf 606 $aEstimation$2imf 606 $aPoverty & precarity$2imf 606 $aPopulation & demography$2imf 606 $aEconometrics & economic statistics$2imf 606 $aPoverty$2imf 606 $aPersonal income$2imf 606 $aIncome distribution$2imf 606 $aPopulation and demographics$2imf 606 $aEstimation techniques$2imf 606 $aIncome$2imf 606 $aPopulation$2imf 606 $aEconometric models$2imf 607 $aNicaragua$2imf 615 0$aPoverty$xMeasurement. 615 0$aIncome distribution$xEconometric models. 615 0$aKernel functions. 615 7$aEconometrics 615 7$aMacroeconomics 615 7$aDemography 615 7$aPoverty and Homelessness 615 7$aWelfare, Well-Being, and Poverty: General 615 7$aPersonal Income, Wealth, and Their Distributions 615 7$aAggregate Factor Income Distribution 615 7$aDemographic Economics: General 615 7$aEstimation 615 7$aPoverty & precarity 615 7$aPopulation & demography 615 7$aEconometrics & economic statistics 615 7$aPoverty 615 7$aPersonal income 615 7$aIncome distribution 615 7$aPopulation and demographics 615 7$aEstimation techniques 615 7$aIncome 615 7$aPopulation 615 7$aEconometric models 676 $a339.46 700 $aMinoiu$b Camelia$0874355 701 $aReddy$b Sanjay$0602369 801 0$bDcWaIMF 906 $aBOOK 912 $a9910817530303321 996 $aKernel Density Estimation Based on Grouped Data$94016246 997 $aUNINA
