[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. The idea is that a consumer will buy a unique ideal amount of each item to minimize the price for obtaining 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: (,) = ∂ (,) ∂ 3 On Shephard’s Lemma It is well-known that Shephard’s lemma is an important tool in both consumer theory and production theory.

Shephard’s Lemma Shephard’s lemma states that if indifference curves of the expenditure or cost function are convex, then the cost minimizing point of a given good (X) with price (PX) is unique.
