∂ π (p) ∂ p = y (p) 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. a price increase is equal to the net supply of the good. from Wikipedia, the free encyclopedia. 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 profit function according to the price of goods results in Hotelling's lemma.

Use the definitions of all these functions to show that Hotelling'slemma is really just a special case of the envelope theorem. Mar 22, 2004 Hotelling's Lemma is simply an application of the envelope theorem. 3. Page 4. 1.2 The Envelope Theorem and Constrained Optimization. Now Abstract The Hotelling game of pure location allows interpretations in As will become clear from the proof of the lemma below, Gk z! corre- sponds to the In solving the problems below, if you use Hotelling's Lemma, you should prove it ( using the Envelope Theorem).

Bei optimaler Produktion ergibt die partielle Ableitung der Gewinnfunktion nach dem Güterpreis die verkaufte Menge, während die partielle Ableitung nach dem jeweiligen Faktorpreis der (negative) Faktoreinsatz ist. Als Hotellings Lemma bezeichnet man in der Mikroökonomik und dort speziell in der Theorie des Unternehmens einige Eigenschaften einer Gewinnfunktion.Es impliziert insbesondere, dass sich aus der Gewinnfunktion unmittelbar die Angebotsfunktion des produzierten Gutes (Outputgutes) und die Nachfragefunktion bezüglich der eingesetzten Faktoren (Inputgüter) ergibt: Bei optimaler Produktion Hotelling's lemma: | |Hotelling's lemma| is a result in |microeconomics| that relates the supply of a good to World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled.

霍特林引理（Hotelling's lemma）是微观经济学中的一个推论，可以由包络定理得到。在给定利润函数π(p,w)情况下，对p求偏导可得产出供给函数，对w求偏导并加负号可得要素L投入需求函数，对r求偏导并加负号可得要素K投入需求函数。最初に説明したとおり、この「L(労働の投入量)」は「L（p,w,r）」と表記できます。利潤関数(π)を要素価格(賃金:w)で偏微分した結果、利潤最大化が実現するときの労働の投入量(要素需要関数)にマイナスを付けたものとなりました。霍特林模型(Hotelling model)埃奇沃思模型的说明描述了只有两个卖者的市场中的不稳定因素。哈罗德·霍特林(Harold Hotelling)在1929年对这一观点提出挑战；他认为价格或产出的不稳定并非是寡头垄断的基本特征。 Hotellings Lemma besagt, dass die allgemeine Faktornachfragefunktion und die allgemeine Angebotsfunktion sich aus der Gewinnfunktion bestimmen lassen. Bei optimaler Produktion ergibt die partielle Ableitung der Gewinnfunktion nach dem Güterpreis die verkaufte Menge, während die partielle Ableitung nach dem jeweiligen Faktorpreis der (negative) Faktoreinsatz ist.

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. He also developed and named the principal component analysis method widely used in

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

Supply function.

Nonrenewable resources; One-sector growth model, Hotelling's Rule, demands for Kand Rcan be found by applying Shephard's Lemma to the cost function:.

The lemma can be stated as: The change in profits from a change in price is proportional to the quantity produced. In this video I'll attempt to explain Hotelling's lemma and prove it mathematically. Hotelling's Lemma: Application of the Envelope Theorem to decisions by a price-taking firm. Hotellings lemma är ett resultat i mikroekonomi som relaterar utbudet av en vara till producentens maximala vinst. Det visades först av Harold Hotelling och används i stor utsträckning i företagets teori . Als Hotellings Lemma bezeichnet man in der Mikroökonomik und dort speziell in der Theorie des Unternehmens einige Eigenschaften einer Gewinnfunktion.Es impliziert insbesondere, dass sich aus der Gewinnfunktion unmittelbar die Angebotsfunktion des produzierten Gutes (Outputgutes) und die Nachfragefunktion bezüglich der eingesetzten Faktoren (Inputgüter) ergibt: Bei optimaler Produktion Hotelling's law is an observation in economics that in many markets it is rational for producers to make their products as similar as possible. This is also referred to as the principle of minimum differentiation as well as Hotelling's linear city model.
