Shephards lemma is a major result in microeconomics having applications in consumer choice and the theory of the firm. Shephards Lemma. Shephards 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 (P X) is unique. the maximand, we get the actual utility achieved as a function of prices and income.

The theory states that the consumer have a unique ideal point at which he may buy the Derive the conditional factor demands for each input and the corresponding production function. Using Shephard's Lemma,. 1 = and 2 = Shephard's lemma states that∂E/∂pi = hi(p1,p2,U),a result that is useful for calculating the welfare consequences of a price change.

2 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 From Shepard's lemma: Since compensated demand depends only on relative factor prices, the demand for labor increases if the user cost of capital goes up:. 3. Show that the expenditure function is concave in p. 4.
