Document Summary

Law of diminishing marginal utility: as the consumption of a product increases, the marginal utility derived from additional consumption will eventually decline. Marginal utility, consumer choice, demand curve of an individual. Marginal benefit = the maximum price a consumer will be willing to pay for an additional unit of the product (the height of the demand curve) Marginal benefit falls as you move down the demand curve. Consumers will maximize utility by ensuring that the last dollar spent on each commodity yields an equal degree of marginal utility: People will buy more (less) of a good as the price of the good decreases (increases) for two reasons: When the price of a good decreases: substitution effect: the good has become cheaper relative to other goods, income effect: it is as if your real income has increased. The cost of time is different for different individuals: Those who earn a higher wage will face a higher time cost.

7. By choosing to consume at the consumer optimum, consumers will

8. A consumer is in equilibrium when consuming two goods when which of the following holds?

MU_a/ P_a = MU_b/ P_b

MU_a/ P_h =MU_b/ P_a

P_a/ MU_a = P_b/ MU_b

MU_a x P_a = MU_bxP_b

9. If the marginal utility of good 1 is 15 and its price is $3, and the marginal utility of good 2 is 12, and its price is $4, then the consumer

should increase his or her consumption of good 1.

12. What is the key to solving the diamond-water paradox?

more water and fewer diamonds

marginal utility

total utility

consumer demand

13. When solving the diamond-water paradox we notice that the marginal utility of

diamonds are equal to the marginal utility of water.

diamonds are greater than the marginal utility of water.

diamonds are less than the marginal utility of water.

water is equal to its price, and therefore lower than the marginal utility of diamonds.

greater than that for diamonds because water is essential.

less than that for diamonds because water is nonessential.

less than that for diamonds because water is essential.

decreases and the marginal utility for water stays the same.
