Document Summary

Income and substitution effects: the inverse relationship between price and quantity demanded is due to the income and sub. If mc > atc, then atc is rising. If mc > avc, then avc is rising. If mc < atc, then atc is falling. If mc < avc, the avc is falling. In the short run, every firm is constrained by some fixed input that leads to diminishing returns to variable inputs and limits its capacity to produce. As a firm approaches that capacity, it becomes increasingly costly to produce successively higher levels of output. Initially increasing and eventually : the envelope relationship, long-run costs are always less than or equal to short-run costs because: In the long run, all inputs are flexible. In the short-run, some inputs are fixed: there is an envelope relationship between long-run and short-run average total cost. If mr>mc, a firm can increase profit by increasing output.

When deciding consumption levels of more than one good, the utility-maximizing rule states that you are maximizing utility when

		the marginal utility o two goods are equal
		the marginal utility of two goods are zero
		the ratio of marginal utility to price of two goods is zero
		the ratio of marginal utility to price for the two goods are equal

QUESTION 2

My brother says the law of diminishing marginal utility is nonsense because he is way happier after his sixth beer than after his first one. Pick the best response.

		He has a point, maybe this is something behavioral economists should take a look at.
		True, but marginal utility refers only to the utility gained (or lost) by drinking that last beer, not to his total utility
		There are always exceptions, but in general this law will hold.
		True, but the law of diminishing marginal utility is really just saying that eventually he will prefer a glass of wine to another beer.

QUESTION 3

Frank spends $75 on 10 magazines and 25 newspapers. The magazines cost $5 each and the newspapers cost $2.50 each. Suppose that his marginal utility from the final magazine is 10 utils while his marginal utility from the final newspaper is also 10 utils. According to the utility-maximizing rule, Frank should:

		Reallocate spending from magazines to newspapers
		Reallocate spending from newspapers to magazines
		Be satisfied because he is already maximizing his total utility
		None of the above

QUESTION 5

In economics, a product provides utility if it:

is useful

violates the law of demand

takes more and more resources to produce successive units of it

satisfies consumer wants

Which of the following is true of an indifference curve?

		Along an indifference curve utility is fixed.
		If a consumer is rational then indifference curves may cross.
		Indifference curves further from the origin are associated with lower levels of utility than those that are closer to the origin.
		Because they are indifference curves, microeconomics students should be indifferent towards them.

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?

After you have eaten 10 chips, 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 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?

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.
