Question

Question 2: Lorelai's choice behavior can be represented by the utility function u(x1, 2)0.9Inx)0.1x2 The prices of both x1 and x2 are $5 and she has an income of $40. 1. What preference does this utility function represent? (Hint: the utility is function is not linear, 2. Drawinwg indifference curves: you can copy down the graph on your paper using econgraphs. Set but at least linear in good x2) the preferences and parameters accordingly as given in the question. Click on "snap to optimal bundle" to see the optimal choice. Click on "show indifference curve map." Draw the lowest four indifference curves as you see from the graph 3. Find the marginal utility of x1 and x2What is the maximum number of x so that MUx, is bigger 4. Given her income of $40, how many units of x1 can she buy? Would she buy any positive number 5. Suppose instead her income is $50. Would she buy any positive number of x2? Find the optimal 6. Find the optimal bundle with an income of $100 using the tangency condition. What happens to than or equal to MUx2? of x2 in light of the answer from Q2.3? Find the optimal bundle. bundle using the tangency condition. the consumption amount of xi compared to the consumption of xi with an income of $50? (Hint In econgraphs, play around by moving an income slide bar and see how the optimal bundle changes.) 7. Will the optimal bundle be the same or different if the utility function were 11(X1 , X2 ) = 91n(xl ) + X2 ? What if the utility function were u(x1 , X2)-TX exp(x2)? Explain.
