Shephard's Lemma Shephard’s lemma is a major result in microeconomics having applications in consumer choice and the theory of the firm. 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.

The lemma states that if indifference curves of the expenditure or cost function are convex , then the cost minimizing point of a given good ( i {\displaystyle i} ) with price p i {\displaystyle p_{i}} is unique. Shepherd’s Lemma e(p,u) = Xn j=1 p jx h j (p,u) (1) differentiate (1) with respect to p i, ∂e(p,u) ∂p i = xh i (p,u)+ Xn j=1 p j ∂xh j ∂p i (2) must prove : second term on right side of (2) is zero since utility is held constant, the change in the person’s utility ∆u ≡ Xn j=1 ∂u ∂x j ∂xh j ∂p i = 0 (3) – Typeset by FoilTEX – 1 Exploring the Shephard's Lemma further It is useful to think about how we derive the Shephard's Lemma especially because it is an excellent application of the envelope theorem. 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.

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.
