Hotelling's Lemma is an envelope theorem. The Lemma applies only for in 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, Lemma 1 In Hotelling's location-then-price game with two types of con- sumers and q1 + q2 = 1 a pure-strategy Bertrand-Nash equilibrium always exists for α It is proved similarly, using.

It was first shown by Harold Hotelling, and is widely used in the theory of the firm.

At a profit maximum, the marginal effect of adjusting production on profits is zero. Harold Hotelling (/ ˈ h oʊ t əl ɪ ŋ /; September 29, 1895 – December 26, 1973) was an American mathematical statistician and an influential economic theorist, known for Hotelling's law, Hotelling's lemma, and Hotelling's rule in economics, as well as Hotelling's T-squared distribution in statistics. Hotelling's rule defines the net price path as a function of time while maximizing economic rent in the time of fully extracting a non-renewable natural resource. The maximum rent is also known as Hotelling rent or scarcity rent and is the maximum rent that could be obtained while emptying the stock resource. As Hotelling's lemma is known in microeconomics and there, especially in the theory of the firm some characteristics of a profit function.In particular, it implies that the supply function of the goods produced (output goods) and the demand function with regard to the factors used ( input goods) result directly from the profit function : With optimal production, the partial derivation of the These instructional videos were prepared by Raphaele Chappe for the MOOC, Advanced Microeconomics for the Critical Mind Hotellings Lemma - Hotelling's lemma Aus Wikipedia, der freien Enzyklopädie Das Lemma von Hotelling ist ein Ergebnis der Mikroökonomie , das die Lieferung eines Gutes mit dem maximalen Gewinn des Herstellers in Beziehung setzt.

If p(p) is twice differentiable, Hotelling's lemma and convexity ofp(p) together imply ¶y i(p) ¶p i ≥0, each i. To strengthen this we may make further assumptions about the Hessian of p(p); alternatively, we may show that arbitrarily close to any po there exist points at which ¶y i(p) ¶p i >0, each i (McFadden, 1978b, p. 403; Takayama We will state here the notation and lemmas that are needed and give only an DISTRIBUTION OF HOTELLING'S GENERALIZED To2 95 outline of the approach … But because they are very useful, we give them a special name: Hotelling's lemma. We will only prove the first result: ∂π * (p,w 1, w 2)/∂w 1 = (p f 1 - w 1) (∂x 1 * /∂w 1) + (p f 2 - w 2) (∂x 2 * /∂w 1) - x 1 * The FOC for profit maximization imply p f 1 - w 1 = 0 and p f 2 - w 2 = 0, so Hotelling's lemma follows.
