For each of the following events, consider how you might react. What things might you consume more or less of? Would you work more or less? Would you increase or decrease your saving? Are your responses consistent with the discussion of household behavior in this chapter? a. You have a very close friend who lives in another city, a 3-hour bus ride away. The price of a round-trip ticket rises from $20 to $45. b. Tuition at your college is cut 25 percent. c. You receive an award that pays you $300 per month for the next 5 years. d. Interest rates rise dramatically, and savings accounts are now paying 10% interest annually. e. The price of food doubles. (If you are on a meal plan, assume that your board charges double.) f. A new business opens up nearby offering part-time jobs at $20 per hour.
A consumer has utility u(x,y) = x^4 y^2 where x is this year’s consumption, and y is next year’s consumption. She makes 600 dollars income this year and 720 dollars income the next year. There is also a bank where she can borrow money at the interest rate r=%50 and lend money (to the bank) at the interest rate r=%20 (of course, she will decide to borrow or lend this year and pay off her debt or receive her savings the next year). a. Should she borrow money from or lend to the bank this year? How much  b. If her utility were u(x,y) = xy2 instead, re-solving (a), would she borrow money or lend? How much? c. If her utility were u(x,y) = x^c y^2, what should “c” be so that she ends up neither borrowing nor lending?
Question Ebrima gets $3 per month as an allowance to spend any way he pleases. Because he likes only peanut butter and jelly sandwiches, he spends the entire amount on peanut butter (at $.05 per ounce) and jelly (at $.10 per ounce). Bread is provided free of charge by a concerned neighbor. Ebrima is a picky eater and makes his sandwiches with exactly 1 ounce of jelly and 2 ounces of peanut butter. He is set in his ways and will never change these proportions.  How much peanut butter and jelly will Ebrima buy with his $3 allowance in a week?  Suppose the price of jelly were to rise to $.15 per ounce. How much of each commodity would be bought?  By how much should Ebrima’s allowance be increased to compensate for the rise in the price of jelly in part b?  Graph your results of part a through part c.  In what sense does this problem involve only a single commodity—peanut butter and jelly sandwiches? Graph the demand curve for this single commodity.  Discuss the results of this problem…
