Abstract: | Deriving comparisons and measures of inequality from full ethical foundations was a main innovation of the 1960s and pursuing
it is still a most fruitful direction. This implies using “equal equivalents” and some principles particularly rich in meanings.
Multidimensional inequalities can be measured and compared thanks to the “equal-equivalent manifolds”. The “equal-equivalent
utility function” defines individual “welfare” cleaned of differences in sui generis individual tastes and hedonic capacities deemed irrelevant for “macrojustice”. Then, equal allocation is a deeper end-value
than equal welfare but has to be complemented by free choice for freedom, Pareto efficiency and a demanded partial self-ownership.
The result is the richly multi-meaning “equal-labour income equalization”. |
