Shephards lemma är ett viktigt resultat i att mikroekonomi har tillämpningar i företagets teori och konsumentval .De lemma anger att om indifferenskurvor av utgifterna eller kostnadsfunktionen är konvexa , då kostnaden minimera punkten för en given bra ( ) med priset är unik.

Roy's identity reformulates Shephard's lemma in order to get a Marshallian demand function for an individual and a good from some indirect utility function. The first step is to consider the trivial identity obtained by substituting the expenditure function for wealth or income w {\displaystyle w} in the indirect utility function v ( p , w ) {\displaystyle v(p,w)} , at a utility of u {\displaystyle u} :

Shephard's lemma is a major result in microeconomics having applications in consumer choice and the theory of the firm . The lemma states that if indifference Oct 24, 2020 It also is shown that Shephard's lemma holds without assuming transitivity and completeness of the underlying preference relation or Jan 11, 2021 We know from Shephard's lemma that whenever the marginal change in expenditure for good 1 with respect to its price varies with the price of must prove : second term on right side of (2) is zero since utility is held constant, the change in the person's utility.

This implies the result known as Shepard’s Lemma (the analogue to Roy’s Identity) that ∂E ∂px = xc (Shepard’s Lemma) Again the (somewhat misleading) intuition for this is clear.

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

In consumer theory, Shephard's lemma states that the demand for a particular good i for a given level of utility u and given prices p, equals the derivative of the expenditure function with respect to the price of the relevant good: (,) = ∂ (,) ∂

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. (4) Example of the constrained envelope theorem (Shephard’s lemma): Let ˆc(¯q,p,w) = w· ˆx be the minimized level of costs given prices (p,w) and output level ¯q. Then the i’th conditional input demand function is ˆx i (·) = Shephard’s Lemma. ∂e(p,U) ∂p l = h l(p,U) Proof: by constrained envelope theorem. Microeconomics II 13 2. Homogeneity of degree 0 in p.
