Through this approach, it is possible to derive index number formulae evolved on ad hoc considerations on the one hand and, on the other, to work out a condition of equivalence giving the "true index" of cost of living. Besides facilitating studies in the problem of index numbers in general, this approach would afford a practicable generalisation for working out multi-dimensional index number formulae.
