Then the i’th conditional input demand function is ˆx i (·) = It is important to note that Shephard’s Lemma 1.1.d is simply an application of the envelope theorem (Samuelson 1947). 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.

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).

That is, is a … We will study the properties of the inverse demand function and of the indirect expenditure function following from hypotheses on normalized prices. It will also be shown that Shephard’s lemma holds without assuming transitivity and completeness of the underlying preference relation or differentiability of the indirect expenditure function.
