Consider a consumer with the Utility function: U = C^1/5 O^ 4/5 and facing a budget constraint: M ≥ PcC +PoO
Note: For this utility function MUC = (1/5)C^-4/5 O^ 4/5 and MUo = (4/5)C^1/5 O^ -1/5 Where C denotes the consumption of corn, and O denotes the consumption of other goods.
A) Derive the Marshallian demand functions for C and O using the equilibrium conditions for an interior solution.
B) Graph and fully label the Demand Curve for corn if income is M=100. To do this, solve for demand when the price of corn is 10, 20, and 40, then approximate the demand curve using these three points.
Solutions
Expert Solution
(a) U = C^1/5 O^ 4/5
MUC = (1/5)C^-4/5 O^ 4/5
MUo = (4/5)C^1/5 O^ -1/5
At equilibrium condition (or utility maximization point), (MUc / MUo) = (Pc / Po)
=> [(1/5)C^-4/5 O^ 4/5 / (4/5)C^1/5 O^ -1/5] = (Pc / Po)
=> [(1/4) O^4/5 * O^1/5 / C^1/5 C^4/5] = (Pc / Po)
=>1/4 (O/C) = (Pc / Po)
=> O = 4C*(Pc / Po) ---------------(1)
---------
Budget constraint: M ≥ PcC +PoO
=> M = PcC +PoO
Put eq(1)
=> M = Pc*C +Po*O
=> M = Pc*C + Po* [4C(Pc/Po)]
=> M = Pc*C + 4C*Pc
=> M = 5C*Pc
=> C = (M/5Pc) ---------------- Marshaliian demand function for C.
Put Marshallian demand function for C in eq (1)
O = 4C(Pc/Po)
> O = 4 * (M/5Pc) (Pc/Po)
=> O = (4/5) (M/Po) -------------------- Marshallian demand function of O
------------------------------------------------------------------------------------------------------------------
(b) C = (M/5Pc)
Put M = 100
=> C = (100 / 5Pc)
=> C = (20 / Pc)
| Price of corn (Pc) | Demand for corn (C) |
| 10 | 2 |
| 20 | 1 |
| 40 | 0.5 |

denotes the consumption of other goods.
A) For corn, characterize the income elasticity of demand, the
price elasticity of demand, the cross price elasticity of demand

versus tomorrow represented by the utility function U(C,C') =
C2/5C'3/5. Let income today is 50, income tomorrow is 20, taxes
today are 10, and taxes tomorrow are 15.

rate, so that the lending rate is only 5% but the borrowing rate is
10%. Calculate the optimal consumption bundle. (hint: the consumer
will be a saver)

Consider an economy where the representative consumer has a
utility function u (C; L) over consumption C and leisure L. Assume
preferences satisfy the standard properties we saw in class. The
consumer has an endowment of H units of time that they allocate to
leisure or labor. The consumer also receives dividends, D, from the
representative Örm. The representative consumer provides labor, Ns,
at wage rate w, and receives dividends D, from the representative
Örm. The representative Örm has a...

function: U(C,L)=5ln(C)+2ln(L) and she has the budget constraint

Following the conventional notation, consider a representative
consumer with the utility function
?(?,?)=??+?
and the budget constraint ???+???≤?. Assume throughout that all
prices and quantities are positive and infinitely divisible.
Derive the consumer’s indirect utility function ?(∙). Assuming
initially that ??=??=1 and ?=10, calculate the change in the
consumer’s utility if the price of good ? doubles, all else
equal.
