On the Possibility of a Weighting System for Functioning

Measuring well-being of an Individual based on his/her levels of functionings raises the following problem; Two vectors representing two individuals' achieved levels of functionings cannot be ranked unless one vector dominates the other, One solution is to combine the elements of vector into some scalar measure by introducing a set of relative weights. Starting from the premise that each individual in a society has his/her own judgment about relative weights for various functionings, an axiomatic approach has been developed to characterize a rule for aggregation of relative weights attached by all individuals in society.
