4. Avinash has preferences over the 2 consumption goods {a, b} that can be represented by the following utility function: U(Ca, Ch) = (C + cf He purchases these goods from his income. p=1- 1/o e (0, 1) Solve for the Marshallian (also known as Walrasian) demands for these preferences. Show that the relative demand function (for good a in terms of good b) can be written as a declining a. b. function of the relative prices alone and is not a function of income. Solve for the expenditure function for these preferences. Find the Hicksian demand function for both goods. Solve for the indirect utility function. Use Roy's identity to solve for the Marshallian demand functions. . d. f. g.
