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. Shephard's Lemma Shephard’s lemma is a major result in microeconomics having applications in consumer choice and the theory of the firm. Shephard’s Lemma Shephard’s lemma states that if indifference curves of the expenditure or cost function are convex, then the cost minimizing point of a given good (X) with price (PX) is unique. ELSEVIER Economics Letters 56 (1997) 359-365 economics letters A further remark on Shephard's Lemma Susanne Fuchs-Selinger* lnstitut fiir Wirtschaftstheorie und Operations Research, Universitiit Karlsruhe, Karlsruhe D-76128, Germany Received 26 December 1996; accepted 18 February 1997 Abstract It is well known that Shephard's Lemma can be proved under very weak assumptions if the input demand Finally, we will be concerned with Shephard’s Lemma which is an important tool in consumer theory as well as in producer theory.

Shephards lemma

The idea is that a consumer will buy a unique ideal amount of each item to minimize the price for obtaining a certain level of utility given the price of goods in the market.

[1]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.

The lemmastates that if indifference curvesof the expenditure or cost functionare convex, then the cost minimizing point of a given good (i) with pricep_iis unique. An explanation of Shephard's Lemma and its mathematical proof. 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.

The lemma states that, for an inﬁnitesimal change in factor price w i(all other factor prices and output remaining constant), the change in minimum cost divided by the change in w i is equal to the equilibrium Shephard's Lemma. Edit.
