Problem 01.
1. In this problem, you are asked to consider cases in which "more is not better." For each of the following scenarios, draw an appropriate indifference curve map over different combinations of Brussels sprouts (X) and broccoli (Y). Put Brussels sprouts (X) on x-axis and broccoli (Y) on Y-axis. Draw 3 indifference curves for each scenario and labeled U1, U2 and U3, from the lowest to the highest utility level.
Hint: to determine the slope of the indifference curves, i.e. whether the indifference curves are upward sloping or downward sloping, start at an arbitrary point (on any indifference curve), reduce the amount of x and ask whether y would have to increase or decrease in order for the person to return to the same indifference curve, i.e., to be indifferent between the original bundle and the new bundle. You can refer to "four particular preferences" in the slides but don't expect the indifference curves to necessarily look like those depicted in slides.
a. I like Brussels sprouts, but I don't like broccoli (Brussels sprouts are an economic good and broccoli is an economic bad.)
b. I don't like Brussels sprouts, and I don't like broccoli.
c. Brussels sprouts are useless for me, and I don't like broccoli.
2. Alan always uses 2oz. of peanut butter and 2oz. of jelly in a PB&J sandwich, and these are the only two commodities he consumes. Assuming he has 2oz. of peanut butter and 2oz. of jelly, how many sandwiches could he make? What if he had 3oz. of peanut butter and 2oz. of jelly? 6oz. of peanut butter and 2oz. of jelly? 2oz. of peanut butter and 4oz. of jelly? Draw his indifference curve for peanut butter (x) and jelly (y) through (2,2). Similarly, draw his indifference curve through (4,4).
3.
Suppose Amy enjoys apple juice (A) and grape juice (G) according to U(A,G) = 4A+3G
a. What does her utility function say about her MRS of apple juice for grape juice?
(Hint: MRS equals the negative value of the slope of indifference curves)
b. Are apple juice and grape juice perfect substitutes or perfect complements? Why?
c. If apple juice costs 6 cents per ounce and grape juice costs 5 cents per ounce, and Amy has 30 cents to spend on these products, how much apple juice and grape juice should she buy to maximize her utility?
d. Draw the graph of her indifference map and her budget constraint, and show that the utility maximizing point occurs only on the A-axis where no grape juice is bought. Hint: to draw the indifference map, please sketch the indifference curves for U=18, and U=20, and give at least two examples of consumption bundles on each indifference curve.
e. Would Amy buy any grape juice if she had more money to spend?
f. How would her consumption change if the price of apple juice fell to 3 cents per ounce?
