Household budget-share distributions and welfare implications: an application of multivariate distributional statistics

In this paper the consequences of considering the household ‘food share’ distribution as a welfare measure, in isolation from the joint distribution of itemized budget shares, is examined through the unconditional and conditional distribution of ‘food share’ both parametrically and nonparametrically. The parametric framework uses Dirichlet and Beta distributions, while the nonparametric framework uses kernel smoothing methods. The analysis, in …
