Abstract

This paper advocates more extensive use of the (Frisch) profit function in static consumer demand studies and intorduces its inverse, the price of utility function, paralleling the well-known relationships between indirect utility and expenditure functions. An examination of the relationship between these four functions suggests: (i) a fourth 'system' complementing Marshallian, Hicksian and Frisch demand systems; and (ii) a fourth 'theorem' complementing Roy's Identity, Shephard's Theorem and Hoteling's Lemma.
