question
Total Utility
answer
is equal to the sum of the marginal utilities of all units consumed.
question
If, as a person consumes more and more of a good, each additional unit adds less satisfaction than the previous unit consumed, we are seeing the workings of
answer
the law of diminishing marginal utility.
question
The law of diminishing marginal utility states that
answer
the extra satisfaction from consuming a good decreases as more of a good is consumed, other things constant.
question
If Callum is consuming his utility maximizing bundle and the price of one good rises, what happens to the marginal utility per dollar spent on this goods (MU/P), and what should Callum do?
answer
MU/P has decreased and Callum should buy less of this good.
question
Along a downward-sloping linear demand curve,
answer
the marginal utility from the consumption of each unit of the good falls and the total utility from consuming larger quantities increases.
