- 7. After receiving good reviews for her work at a series of art shows, Jean Rodin considers quitting her job as a management consultant to pursue full time her hobby of sculpting. Jean figures that she can sell $100,000 worth her art each year. She found a studio that she can rent for $2,000 per month and know that materials will cost her $20,000 per year. She now earns $90,000 per year. If her calculations are correct, Jean's annual economic profits from the venture will be. a) $80,000 b) $56,000 c) $10,000 d) -$34,0002. Determining opportunity cost Juanita is deciding whether to buy a suit that she wants, as well as where to buy it.

The opportunity cost of holding money Suppose you've just inherited $5,000 from a relative. You're trying to decide whether to put the $5,000 in a non-interest-bearing account so that you can use it whenever you want (that is, hold it as money) or to use it to buy a U.S. Treasury bond. The opportunity cost of holding the inheritance as money depends on the interest rate on the bond. For each of the interest rates in the following table, compute the opportunity cost of holding the $5,000 as money. Interest Rate on Government Bond Opportunity Cost (Dollars per year) (Percent) What does the previous analysis suggest about the market for money? The quantity of money demanded increases as the interest rate falls. The quantity of money demanded decreases as the interest rate falls. O The supply of money is independent of the interest rate.

David gets $3 per week as an allowance to spend any way he pleases. Since he likes only peanut butter and jelly sandwiches, he spends the entire amount on peanut butter (at $0.05 per ounce) and jelly (at $0.1 per ounce). Bread is provided free of charge by a concerned neighbor. David 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. a) How much peanut and jelly will David buy with his $3 allowance per week? b) Suppose the price of jelly increases to $0.15 per ounce. How much of each commodity would be bought? c) By how much should David's allowance be increased to compensate for the rise in the price of jelly in part b? d) Graph your results of part a through part c.
- 4. Shifts in production possibilities Suppose the United Kingdom produces two types of goods: agricultural and capital. The following diagram shows its current production possibilities frontier for barley, an agricultural good, and cars, a capital good. Drag the production possibilities frontier (PPF) on the graph to show the effects of an immigration law that results in fewer workers entering the country. Note: Select either end of the curve on the graph to make the endpoints appear. Then drag one or both endpoints to the desired position. Points will snap into position, so if you try to move a point and it snaps back to its original position, just drag it a little farther. ?

- 2. Utility maximization - Trading off labor and leisure The indifference curves on the following graph show Amy's preferences for leisure and consumption for increasing levels of utility, such that her utility increases in both consumption and leisure. Assuming that Amy spends 68 hours each week sleeping, she has a maximum of 100 hours available to her for leisure if she does not work at all. Initially, she works 45 hours (and thus has 55 hours of leisure) and earns $250 per week. Use the grey point (star symbol) to indicate Amy's initial leisure/consumption bundle. Dashed drop lines will automatically extend to both axes.
