Welfare function

the welfare function is a characteristic number suggested by Amartya Sen.

Welfare function = gross national income × (1 - unequal distribution coefficient)

as unequal distribution coefficient can be consulted for example the Gini coefficient, which was determined for the unequal distribution of the incomes in a country. Suitably also every other relative unequal distribution coefficient, the values is in the range between 0 and 1 (and/or. 0% and 100%) to assume can. James E. Foster (S. Literature) suggested for example the Atkinson coefficient ( an entropy measure).
