I'd like to make two comments. First, there is a large, highly advanced, but almost entirely overlooked literature on multidimensional poverty measurement. I encourage those who are interested to look at the work of Maasoumi, Silber, Kakwani and many others. Secondly, the information theoretic approaches (by Maasoumi et al) provide a unique empirical criteria to compute the otherwise "arbitrary" weights. Unfortunately, the Bank has so far focused on the mainstream literature.
