Document Summary

Uility; saisfacion that consumer receives from consuming good/service. Total uility; total saisfacion resuling from consumpion of given commodity by consumer. Marginal uility; addiional saisfacion obtained from consuming one addiional unit of commodity. Diminishing marginal uility; oten called law of diminishing marginal uility: uility any consumer derives from successive unites of paricular product consumed over period of ime diminish as total consumpion of product increases. As consumpion increases, total uility rises, and marginal uility falls. Uility maximizing consumer allocates expenditures so marginal uility obtained from last dollar spent on each product is equal. Increase in quanity = decrease in marginal uility. Condiion for consumer to maximize uility, for any pair of products: mux /px = muy /py. When condiion is met for all goods, consumer cannot increase uility further. Relaive price of two goods: determined by market, beyond consumer"s control, let side is relaive ability of two goods to add to consumer"s uility, mux / muy = px /py.

1. Use the table below for the following question. Suppose you have a budget of $6 and that brownies and Twizzlers cost $1 each. What is the consumer optimum?

Number of Brownies	Total Utility of Brownies	Marginal Utility of Brownies	Number of Twizzlers	Total Utility of Twizzlers	Marginal Utility of Twizzlers
0	0	-	0	0	-
1	10	10	1	6	8
2	19	9	2	13	7
3	26	7	3	19	6
4	30	4	4	23	4
5	30	0	5	25	2
6	29	-1	6	25	0

6 brownies

3 brownies and 3 Twizzlers

4 brownies and 2 Twizzlers

any combination of 6 because they're both $1

2. Use the table below for the following question. What is the consumer equilibrium for a $6 budget if the price of brownies rises to $1.50 and the price of Twizzlers remains at $1.00?

Number of Brownies	Total Utility of Brownies	Marginal Utility of Brownies	Number of Twizzlers	Total Utility of Twizzlers	Marginal Utility of Twizzlers
0	0	-	0	0	-
1	10	10	1	6	8
2	19	9	2	13	7
3	26	7	3	19	6
4	30	4	4	23	4
5	30	0	5	25	2
6	29	-1	6	25	0

The consumer will buy all Twizzlers because they're cheaper.

4 brownies

3 Twizzlers and 2 brownies

3 brownies and 3 Twizzlers

3. At Nice Price for the Ice, an ice cream parlor, customers routinely buy a scoop of ice cream for $3. If consumers purchase one scoop of ice cream at $3, then why don't they keep buying more and more scoops for $3 until the store sells out?

People would not want more than one scoop of ice cream because then they would have less money to spend on other goods.

People do not want to consume all the scoops of ice cream because their total utility is higher the less they eat.

At some point, customers do not value an additional scoop at $3, so they will not pay $3 for a scoop after they reach that point.

4. Suppose you plan on eating 50 potato chips. As you start consuming potato chips, your marginal utility is very high, but it begins to fall slowly until you've eaten 10 chips. After you have eaten 10 chips, your marginal utility decreases even faster with each additional chip. The marginal utility continues to decline until you've eaten 49 chips. The fiftieth chip does not give you any additional utility. After 50 chips, your mouth gets so salty that it's unpleasant to eat anymore, so marginal utility is actually negative for those chips. How many chips should you eat in order to maximize your total utility?

The fiftieth chip does not give you any additional utility. After 50 chips, your mouth gets so salty that it's unpleasant to eat anymore, so marginal utility is actually negative for those chips. How many chips should you eat in order to maximize your marginal utility?

6. At current levels of consumption, Alice is spending her entire budget. If Alice gets 3 utils of satisfaction per dollar spent on ice cream and 2 utils per dollar spent on shampoo, then how should she adjust her consumption to get closer to the consumer optimum?

She is already at the consumer optimum, so no adjustment is necessary.

She should buy more ice cream and less shampoo.

She should buy more shampoo and less ice cream.

She should buy more of both goods.

7. Suppose you are at a restaurant and your favorite dish costs $20. You can get your next-favorite dish for $17. If your next-favorite dish gives you 100 utils, how many additional utils do you need from your favorite dish to spend the extra $3?

17.65

117.65

8. The diamond water paradox is the observation that water is essential to life and inexpensive, while diamonds are not essential and are highly-priced. Which of the other pairs of goods exhibit a pricing structure similar to water and diamonds?

economy & luxury cars

rice & truffles (very expensive mushrooms)

paper clips & gasoline

paper & textbooks

9. Rice is a cheap staple food eaten several times a day by many people all over the world. In Trufflelandia, residents also eat expensive mushrooms known as truffles once every year as a birthday celebration. Rice keeps the people alive and truffles are not necessary for sustaining their lives. Why is rice so cheap and truffles so expensive?

Truffles taste better, so they are worth more money.

Rice is easy to cook, so people buy a lot of it. If people are going to buy so much, then it has to be cheap.

Truffles are more nutritious, and healthy food is always more expensive than unhealthy food.

People eat so much rice that an additional serving of rice has little marginal value, but the marginal value of another serving of truffles is very high.
