第1题
a.计算每年苹果的消费者物价指数。假设第一年是基年,消费者的篮子固定在基年。从第1年到第2年,你计算的指数如何变动?
b.计算阿贝每年对苹果的名义支出。从第一年到第二年,这种名义支出有什么变动?
c.把第一年作为基年,计算阿贝每年对苹果的实际支出。从第一年到第二年,这种实际支出有什么变动?
d.把隐含的物价平减指数定义为名义支出除以实际支出,计算每年的平减指数。从第一年到第二年,平减指数有什么变动?
e.假设阿贝吃红苹果或青苹果同样快乐。阿贝的真实生活费用增加了多少?比较这一答案和你对(a)与(b)的答案。这个例子告诉了你关于拉斯派尔和帕氏物价指数的什么?
Abby consumes only apples. In year 1, red apples cost $1 each, green apples cost $2 each, and Abby buys 10 red apples. In year 2, red apples cost $2, green apples cost $1, and Abby buys 10 green apples.
a.Compute a consumer price index for apples for each year. Assume that year 1 is the base year in which the consumer basket is fixed. How does your index change from year 1 to year 2?
b.Compute Abby's nominal spending on apples in each year. How does it change from year 1 to year 2?
c.Using year 1 as the base year, compute Abby's real spending on apples in each year. How does it change from year 1 to year 2?
d.Defining the implicit price deflator as nominal spending divided by real spending, compute the deflator for each year. How does the deflator change from year l to year 2?
e.Suppose that Abby is equally happy eating red or green apples, How much has the true cost of living increased for Abby? Compare this answer to your answers to parts (a) and (d). What does this example tell you about Laspeyres and Paasche price indexes?
