Hotelling's lemma is a result in microeconomics that relates the supply of a good to the profit of the good's producer. It was first shown by Harold Hotelling, and is widely used in the theory of the firm. Hotelling's lemma is a result in microeconomics that relates the supply of a good to the maximum profit of the producer.

As Hotelling's lemma is known in microeconomics and there, especially in the theory of the firm some properties of a profit function. It implies in particular that from the profit function directly the supply function of the produced goods ( output good), and the demand function with respect to the employed factors ( input goods ) effects: For optimum production, therefore, yields the partial derivative of the profit function after the goods price, the quantity sold, while Hotelling's lemma is stated as: ∂π ∂p = y. knowing however that on the more basic level, output y is determined by the input (s) x(p, w) ,let the profit function be defined as: π = py(x(p, w)) − wx(p, w) taking the derivative with respect to p. ∂π ∂p = y(x(p, w)) + p∂y(x(p, w)) ∂x(p, w) ∂x(p, w) ∂p − w∂x(p, w) ∂p. Hotelling's theory, or Hotelling's rule, posits that owners of non-renewable resources will only produce a supply of their basic commodity if it can yield more than available financial instruments, (3) Example of the unconstrained envelope theorem (Hotelling’s lemma): Let π∗(p,w) = pf(x∗) −w· x∗ be the maximized value of proﬁts given output price p and input price vector w.

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. In other words, if the firm makes its choices to

Using the new interpretation of Hotelling's lemma, the authors reconstruct the cost function and confirm the Conjugate Duality Theorem of Legendre-Fenchel transformations. Relaxing the assumption of differentiability by describing the graph of the cost function as the envelope of its tangents, the authors rederive the properties of Legendre-Fenchel transformations and show that they hold in
