Shephard's Lemma 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. 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. In Consumer Theory, the Hicksian demand function can be related to the expenditure function by Analogously, in Producer Theory, the Conditional factor demand function can be related to the cost function by The following derivation is for relationship between the Hicksian demand and the expenditure function. The derivation for conditional factor demand and the cost function is identical, only The lemma is named after Ronald Shephard who gave a proof using the distance formula in his book Theory of Cost and Production Functions (Princeton University Press, 1953). The equivalent result in the context of consumer theory was first derived by Lionel W. McKenzie in 1957.

The first step is to consider the trivial identity obtained by substituting the expenditure function for wealth or income w {\displaystyle w} in the indirect utility function v ( p , w ) {\displaystyle v(p,w)} , at a utility of u {\displaystyle u} : 2020-10-24 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. 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 (4) Example of the constrained envelope theorem (Shephard’s lemma): Let ˆc(¯q,p,w) = w· ˆx be the minimized level of costs given prices (p,w) and output level ¯q.
