Suppose Smith from Problem 7 views current and future consumptio complements. Find his optimal consumption bundle in both cases. 10. Karen earns $75,000 in the current period and will earn $75,000 in the future. a. Assuming that these are the only two periods, and that banks in her and lend at an interest rate r = 0, draw her intertemporal budget const b. Now suppose banks offer 10 percent interest on funds deposited d u u‘ period, and offer loans at this same rate. Draw her new intertemporal b 11.

Q Crusoe will live this period and. the next period as the lone inhabitant of his 6 income is a crop of 100 coconuts that he harvests at the beginning of each not consumed in the current period spoil at the rate of 10 percent per period, a. Draw Crusoe’s intertemporal budget constraint. What will be his cons period if he regards future consumption as a perfect one~for-one substi consumption? b. What will he consume each period if he regards 0.8 unit of future cons r worth 1 unit of current consumption?
