Predicting social assistance beneficiaries: On the social welfare damage of data biases

14 Aug 2024  |  www.idos-research.de
Cash transfer programs are a prevalent anti-poverty tool in low- and middle-income countries, benefiting over a billion people globally. This paper introduces an extended targeting assessment framework for proxy means testing, which considers societal sensitivity to targeting errors. By weighting targeting errors based on their position in the welfare distribution and adjusting for societal inequality aversion, the framework offers a more comprehensive assessment of targeting performance. However, case studies reveal that data biases, such as label bias and unstable proxy means testing weights, significantly underestimate welfare losses, disproportionately disadvantaging certain groups.
