1. A utility function that represents preferences:

a) Assigns the same number to bundles that lie on the same indifference

curve and higher number to bundles that are preferred.

b) Assigns the smae number to bundles that lie on the same indifference

curve and lower number to bundles that are preferred.

c) Assigns same number to all bundles.

d) Assigns different numbers to bundles that lie on the same indifference

curve.

Ans:無

這題題目看不太懂

但我猜是在說效用函數是指不同財貨組合所形成的同一條無異曲線

故選(D) 各位覺得呢


2. If individuals have different preferences but society's preferences

are consistent with the aggregation of individual preferences,

which of the following is true?

a) All endowments are equal.

b) There are only two individuals in the society.

c) Society's preferences are determined by a single individual

d) The social welfare function is Rawlisn.

Ans:無

個人認為是(a) 因為當每個人稟賦相同時

每個人的偏好都將相同

故社會總偏好也會與個人偏好一致

那請問 (d)的答案又是甚麼呢???

3. The purchasing power parity approach is a more useful method

used to compare the standard of living of different countries because:

a) using current exchange rates, which can vary a lot, cause large

fluctuations in output per capital among countries.

b) current exchange rates do not take account differences in prices of basic

goods among countries.

c) the PPP method does not ignore differences in the prices of basic goods,

d) all of above

Ans:無

這題也不太懂

我只知道購買力平價說在講 e=Pd/Pf

可是跟這題有甚麼關聯呢??


麻煩各位大大幫忙解題!
