The Properties of the Watts Poverty Index under Lognormality

    (University of Nottingham)

Abstract

Under lognormality assumption, we derive the parametric formula of the Watts measure, one of the main axiomatically sound poverty measures. In these conditions, we derive new properties of the Watts measure, its sensitivity to distribution parameters and its parametric standard error.
