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. Die beiden

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

谢泼德引理（Shephard's lemma）是微观经济学中的一个重要结论，可以由包络定理得到。 在给定支出函数情况下，对p求偏导可得到希克斯需求函数。

The expenditure function is the minimand of the constrained optimization problem characterized by the following Lagrangian: Use Shephard’s lemma and Roy’s identity to retrieve Hicksian demand and expenditure function. Steps: 1. Using Roy’s identity, we can retrieve the indirect utility function (solve differential equation in v(w,p)) 2. Invert the indirect utility to get the expenditure function: v(e(u,p),p) = u 3.
