Reliability, Population Classification and Weighting in Multidimensional Poverty Measurement: A Monte Carlo Study
TLDR
A Monte Carlo study based on factor mixture models is used to draw up a series of uni-and multidimensional poverty measures with different reliabilities and predefined groups and shows that low reliability results in a high proportion of the poor group erroneously classified as part of the not poor group.Abstract:
In poverty measurement, differential weighting aims to take into account the unequal importance of the diverse dimensions and aspects of poverty and to add valuable information that improves the classification of the poor and the not-poor. This practice, however, is in contention with both classical test theory and modern measurement theories, which state that high reliability is a necessary condition for consistent population classification, while differential weighting is not so. The literature needs a clear numerical illustration of the relationship between high/low reliability and good/poor population classification to dissolve this tension and assist applied researchers in the assessment of multidimensional poverty indexes, using different reliability statistics. This paper uses a Monte Carlo study based on factor mixture models to draw up a series of uni-and multidimensional poverty measures with different reliabilities and predefined groups. The article shows that low reliability results in a high proportion of the poor group erroneously classified as part of the not poor group. Therefore, reliability inspections should be a systematic practice in poverty measurement. The article provides guidelines for interpreting the effects of unreliability upon adequate population classification and suggest that the classification error of current unreliable multidimensional indexes is above 10%.read more

TL;DR: In this article, the authors present a method for specifying and measuring poverty, defined as relative deprivation, based on the distance between an individual's consumption experience and the social norm, where consumption experience is defined in terms of events and the modal frequency of an event in the community defines the norm.
