The paper examines the problem of optimal targeting when households differ in needs. Additively decomposable poverty measures based on the households' deprivation are employed. Needs are modelled carefully: household size and needs are reflected by equivalence scales and weights. The paradox of...

This paper studies the influence of productivity, pollution sensitivity, and adaptive capacity on optimal mitigation and adaptation in a two country global pollution model. We investigate the effects of changes of these parameters on the allocation of emissions, adaptation expenditures, and...

Equivalence scales are typically designed for adjusting households' incomes for differences in size and composition. On the one hand, there is evidence that the way differences in needs across households are taken into account has a significant impact on the assessment of inequality in the...

The paper characterizes the class of weakly decomposable (aggregable) inequality measures which satisfy a new (weak) decomposition (and agregation) property. These measures can be decomposed into the sum of the usual within-group and a between-group term which is based on the inequality between...
