Finally, we will be concerned with Shephard’s Lemma which is an important tool in consumer theory as well as in producer theory. It will be shown that Shephard’s lemma holds without imposing

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} :

Second, a uniform commodity tax increases unit costs in all household production activities but, by Shephards Lemma, costs go up by more in goods intensive  Shephard's Lemma and the Elasticity of Substitution 355.

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. (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.
