In this paper I show that recently proposed methods to quantify the level of inequality of opportunity are likely to be downward biased when the dependent variable is a proxy for an unobserved concept. Using a multidimensional framework of development, such as the capability approach, or a...

This paper discusses the measurement of ex-ante inequality of opportunity for binary outcome variables. We argue that the use of scale but not translation invariant inequality measures such as the dissimilarity index might be problematic depending on the aim of the study. The main concern is...
