Question 4
Solving Consumer's Choice Problem under CD Utility, Numerical
The consumer with income Y has a preference represented by CD utility function
U(91,92) = 90.492.6.
Given prices for the two goods, denoted by P₁, P2, solve the consumer's optimal choice
problem following the steps below.
(a) Write down the consumer's maximization problem, i.e be clear about (1) the choice
variables, (2) the objective function and (3) the constraint. mand
(b) Write down the Lagrangian for this optimization problem.
(c) Derive the three first-order conditions.

(d) Solve for the optimal consumption bundles q1,92.
(e) Plugging optimal consumption bundles q,q into U(91,92) to get the expression
for indirect utility function, i.e. utility as a function of Y, P₁, P2.
(f) Now we analyze the properties of demand. How does q respond to changes in
P₁, P2 and Y? Specifically, does q increase or decrease if
1. p₁ increases?
2. p2 increases?
3. Y increases?

Jane receives utility from days spent traveling on vacation domestically (D) and days spent traveling on vacation in a
foreign country (F), as given by the utility function U(D,F)= 10DF. In addition, the price of a day spent traveling
domestically is $100, the price of a day spent traveling in a foreign country is $400, and Jane's annual travel budget is
$4000.
An indifference curve associated with a level of utility equal to 800 and an indifference curve associated with utility of
1200 are illustrated in the figure to the right.
Using the line drawing tool, graph Jane's budget line. Label this line L,.
Carefully follow the instructions above, and only draw the required object.
Can Jane afford any of the bundles that give her a utility of 800?
Can Jane afford any of the utility bundles that give her a utility of 1200?
Find Jane's utility-maximizing choice of days spent traveling domestically and days spent in a foreign country.
days of domestic travel and days of foreign travel. (Enter…

- urgentarrow_forwardText: Consider a consumer whose preferences are characterized by the utility function u(x1, X2) = In x1 + x2. This utility function is often used to represent the tastes of a consumer to whom good 1 is essential, while good 2 is not. Furthermore, the tastes represented by this utility function satisfy the five standard assumptions about tastes introduced in the lectures. Based on this information, answer the following questions Questions: Which of the following maps of indifference curves could be the one associated with the utility function above?
