6) Shephard's Lemma: Hicksian Demand and the Expenditure Function . We can also estimate the Hicksian demands by using Shephard's lemma which stats that the partial derivative of the expenditure function Ι . with respect to the price i is equal to the Hicksian demand for good i. The general formula for Shephards lemma is given by

Inthecasewhere Visstrictlyquasi-concaveand V(y)isstrictlyconvex the cost minimizing point is unique. Rockafellar [14, p. 242] shows that the cost function is differentiable Shephard's lemma is a major result in microeconomics having applications in the theory of the firm and in consumer choice. The lemma states that if indifference curves of the expenditure or cost function are convex, then the cost minimizing point of a given good () with price is unique. Theorem between cost and production functions. Section 4 explains Shephard’s Lemma; i.e., it shows why differentiating a cost function with respect to input prices generates the vector of cost minimizing input demand functions.

To eksempel er den høyeste nytten en konsument kan oppnå, som en funksjon av priser og inntekt eller den laveste kostnaden som gjør det mulig å nå et nyttenivå, som funksjon av priser og nyttenivå. 2021-03-09 · Shephards Lemma besagt in der Haushaltstheorie, dass die Hicks’sche Nachfragefunktion nach einem Gut der Ableitung der Ausgabenfunktion nach dem Preis dieses Gutes entspricht. In der Theorie des Unternehmens besagt es, dass die bedingte Faktornachfrage nach einem Produktionsfaktor der Ableitung der Kostenfunktion nach dem Faktorpreis dieses Produktionsfaktors entspricht.
