Also available as App! Application. Shephard's lemma gives a relationship between expenditure (or cost) functions and Hicksian demand. The lemma can be re-expressed as Roy's identity, which gives a relationship between an indirect utility function and a corresponding Marshallian demand function. Shephard’s Lemma. If indifference curves are convex, the cost minimizing point is unique. Then we have ∂C(u,p) ∂pi = hi(u,p) (12) which isaHicksianDemand Curve.

[1]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. Theorem between cost and production functions. Section 4 explains Shephard’s Lemma; i.e., it shows why differentiating a cost function with respect to input prices generates the vector of cost minimizing input demand functions.

The 1957 paper appears to include the first derivation of Shephard's lemma in the context of consumer theory. Roy's identity reformulates Shephard's lemma in order to get a Marshallian demand function for an individual and a good (i) from some indirect utility function.
