![**Question 5: Solving Consumer's Choice Problem under CES Utility: Numerical (Sympy Solution Not Required)**
The consumer with income \( Y \) has a preference represented by the CES utility function:
\[ U(q_1, q_2) = (q_1^{0.4} + q_2^{0.4})^{1/0.4} \]
Given prices for the two goods, denoted by \( p_1, p_2 \), 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.
(b) **Write down the Lagrangian for this optimization problem.**
(c) **Derive the three first-order conditions.**
(d) **Solve for the optimal consumption bundles \( q_1^*, q_2^* \).**
(e) Now we analyze the properties of demand. How does \( q_1^* \) respond to changes in \( p_1, p_2 \) and \( Y \)? Specifically, does \( q_1^* \) increase or decrease if:
1. \( p_1 \) increases?
2. \( p_2 \) increases?
3. \( Y \) increases?
For simplicity, we only analyze \( q_1^* \); results for \( q_2^* \) are similar. (Hint: comparative statics, calculate \(\frac{\partial q_1^*}{\partial p_1}\), etc.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2e6f77a4-2bfc-4d58-b6c2-577005b77990%2F9dafd475-8d6a-4b20-bf75-ce299a879938%2F0h77ezd_processed.jpeg&w=3840&q=75)
