which implies that the second term in 4 is zero. This implies the result known as Shepard’s Lemma (the analogue to Roy’s Identity) that ∂E ∂px = xc (Shepard’s Lemma) Again the (somewhat misleading) intuition for this is clear. If pxchanges by a small amount then xcwill

Continuous in p and u. 5. If u(·) is strictly quasi-concave and e(p, u) is differentiable we have Shephard's lemma. Sep 12, 2019 Directly use the Shepard's Lemma, we have the Hicksian demand system ωi = αi +. ∑ j γij ln pj + βilog [w/P] , ∀i ln P = α0 +.

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. The idea is that a consumer will buy a unique ideal amount of each item to minimize the price for obtaining a A short video discussing the uses of shephard's lemma in consumer theory.
