You consume music (M) and concert tickets (C). Your utility function is U(M, C) = M1/4C3/4. The marginal utility for concert tickets, MUC is MUC =3/4C-1/2M1/4 and the marginal utility for music, MUM is MUm = 1/4C3/4M-3/4   (a) Calculate MRSMC using only the given marginal utilities. (b) Solve for the utility of bundle A where M = 16 and C = 16. Solve for your utility at bundle B where M = 128 and C = 8. Are the utilities the same? (c) Calculate MRSMC at bundle A and at bundle B. Are they the same?

Question

You consume music (M) and concert tickets (C). Your utility function is U(M, C) = M1/4C3/4. The marginal utility for concert tickets, MUC is MUC =3/4C-1/2M1/4 and the marginal utility for music, MUM is MUm = 1/4C3/4M-3/4  

(a) Calculate MRSMC using only the given marginal utilities.
(b) Solve for the utility of bundle A where M = 16 and C = 16. Solve for your utility at bundle B where M = 128 and C = 8. Are the utilities the same?
(c) Calculate MRSMC at bundle A and at bundle B. Are they the same?
(d) Are your indifference curves convex? Draw the ICs. Make sure to label the quantities of the consumption bundles, the axis, and the MRS at those bundles.

Expert Solution
Step 1

A consumer maximizes her or her utility given his or her budget constraint at the point where the slope of his indifference curve equals the slope of his budget line. Mathematically, it is 

Px/Py = MUx/MUy

Where Px is the price of good X, Py is the price of good Y. MUx is the marginal utility from good X and MU is the marginal utility from good Y.
