Although Shephard's lemma was developed for the cost function of an unregulated firm, z it has also been applied to the cost function of a rate of return regulated firm. 3 However, for this latter case no formal proof has yet been stated. 5.3.

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 idea is that a consumer will buy a unique ideal amount of each item to minimize the price for obtaining a A short video discussing the uses of shephard's lemma in consumer theory.

Introduction In this paper conditions implying the validity of Shephard's Lemma will be reconsidered. In a former paper, Fuchs-Seliger (1990), I have imposed mild conditions on the preference relation of the individual, which already imply Shephard's Lemma.

Application of the Envelope Theorem to obtain a firm's conditional input demand and cost functions; and to consumer theory, obtaining the Hicksian/compensate Hotelling's lemma is a result in microeconomics that relates the supply of a good to the maximum profit of the producer. It was first shown by Harold Hotelling, and is widely used in the theory of the firm. Specifically, it states: The rate of an increase in maximized profits w.r.t.

Property 1.1.a is obvious from Equation (1.1), and 1.1.b follows from the fact that an equiproportional change in all factor prices wdoes not change relative factor prices and hence does not change the cost-minimizing level of inputs x for problem (1.1).
