The lower orthant dominance relation is frequently used for multidimensional social welfare comparisons. Recently it has been shown that bivariate dominance can be characterized in terms of elementary mass transfer operations. We provide an algorithm which explicitly decomposes the mass...

We consider the problem of distributing the proceeds generated from a joint venture in which the participating agents are hierarchically organized. We characterize a family of allocation rules ranging from the so-called zero-transfer rule (which awards agents in the hierarchy their individually...

This paper proposes a concept of inequality comparisons with ordinal multidimensional categorical data. In our model, one population is more unequal than another when they have common arithmetic median outcomes and the first can be obtained from the second by correlation-increasing switches...

A propitiously timed household survey carried out in Mozambique over the period 2008-09 permits us to evaluate the short-to-medium run relationship between sudden shocks to food prices and child nutrition status. We link local price inflation with child malnutrition status. We find that the...
