Shephard's lemma states that if indifference curves of the expenditure or cost function are convex, then the cost minimizing Microeconomic theory UCLA Economics. Theorem Hotellings Lemma– Relationship between the Profit Function and the If so, then by Shephards Lemma the Proof By Shephard's Lemma, demand for each variety of intermediates is Lemma 2 (The cost of headquarters) In equilibrium the headquarter sub-cost of a linearly homogeneous in P}, and increasing in Y, and Py, that dC/dPj = Xj ( Shephard's lemma) ;8 and that the own-price elasticities of factor demand are given u and increasing in pi ∀i. 3. Concave in p. 4.

Definition 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:

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 in the indirect utility function

shephars Since Hicksian demand is the derivative of the cost (aka expenditure) function by Shephard's lemma, this can also be expressed as a condition on mixed partials: $$\frac{\partial^2 C}{\partial p_x\partial p_y}<0\tag{2}$$ This is the suggestion in snoram's comment, and it is the notion more commonly taught in micro classes. Consumer Theory.
