Question
A consumer buys two goods, x 1 and x 2 , in order to achieve the utility given by: u (x 1 , x 2
A consumer buys two goods, x1 and x2, in order to achieve the utility given by: u (x1, x2) = 2 ln x1 + 3 ln x2. She is required to spend exactly her income of I dollars on x1 and x2, which have prices equal to p1 > 0 and p2 > 0, respectively. 1. Write down the constrained optimization problem that captures the consumer's decision.
2. Solve for the consumption bundle (x1,x2) that maximizes her utility. Note that these should be functions of the parameters I, p1, p2.
3. Show that the optimal bundle x*1 is decreasing in p1 and increasing in I. (Hint: Use partial derivatives).
