An explanation of Shephard's Lemma and its mathematical proof. 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. This video explains the Hicksian Demand Functions, Expenditure Function and Shephard's Lemma.

"Shephard’s Lemma" published on 31 Mar 2014 by Edward Elgar Publishing Limited. Use Shephard’s lemma and Roy’s identity to retrieve Hicksian demand and expenditure function. Steps: 1. Using Roy’s identity, we can retrieve the indirect utility function (solve diﬀerential equation in v(w,p)) 2. Invert the indirect utility to get the expenditure function: v(e(u,p),p) = u 3.

Obtain the Hicksian demand using Shephard Applying Shephard’s Lemma, @e(p;u) @pi = xh(p;u); (10) to (9) gives xh(p;u) = u ii pi (∏ i (1 i) )∏ i (pi) i: (11) Notes 1Named after Charles W.

L x = x h;y = y h = px x h + py yh + h u u (x h;yh) i = px x h + py yh = E ( u;p x;py) Envelope Theorem This is because if u u (x h;yh) = 0 . Since x h and y h are the solution Shephard's Lemma - 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: where hi(p,u) is the Hicksian demand for good, e (p,u) is the expenditure function, Shephard's lemma. is a major result in microeconomics having applications in consumer choice and the theory of the firm.

ELSEVIER Economics Letters 56 (1997) 359-365 economics letters A further remark on Shephard's Lemma Susanne Fuchs-Selinger* lnstitut fiir Wirtschaftstheorie und Operations Research, Universitiit Karlsruhe, Karlsruhe D-76128, Germany Received 26 December 1996; accepted 18 February 1997 Abstract It is well known that Shephard's Lemma can be proved under very weak assumptions if the input demand 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 In this paper Shephard's Lemma will be proved under very weak conditions. Neither the differentiability of the cost function nor the transitivity and completeness of the underlying preferences will be assumed.
