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. Cobb and Paul H. Douglas, who published an econometric analysis of the relation between labour, capital and output in AER 1928. They used this type of specification.

The idea is that a consumer will buy a unique ideal amount of each item to minimize the price for obtaining a certain level of utility given the price of goods in the market.

[1]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. Theorem between cost and production functions. Section 4 explains Shephard’s Lemma; i.e., it shows why differentiating a cost function with respect to input prices generates the vector of cost minimizing input demand functions.
