[考試] 邊際效用
來源: 97 年度研究所考
科目: 經濟
問題:the law of diminishing marginal utility implies that
a) the marginal utility of a product is negative
b) the total utility from a product is also diminishing
c) the rate of change of total utility is diminishing
d) the rate of change of marginal utility is dimishing
高點參考的解答為c 個人認為是d
應該是邊際效用的改變是遞減
為何是總效用遞減??
