                                                               year 2000              year 2005

price of an automobile                            $50,000                 $60,000

price of a loaf of bread                           $10                        $20

number of automobiles produced           100                        120

number of loaves of bread produced      500,000                 400,000

问题如下

1 using the year 2000 as the base year, compute nominal GDP in each year

2 using the year 2000 as the base year, compute  real GDP in 2005

3 using the year 2000 as the base year, compute the implicit deflater for GDP in 2005

4 using the year 2000 as the base year, compute  a fixed- weight price indes such as the CPI in2005

5 for the previous two questions , compute the inflation rate

6 suppose you are a senator writing a bill to index , Social Security and federal pensions. that is, your bill will adjust these benefits to offset changes in the cost of living. Will you use the GDP deflater or the CPI? why?

3,4差别在是不是在固定权重上，

3权重数量变了，4没变。

5，不明白，这个可以由好几种指数表示，包括cpi和gdp deflator等。

6，应该是cpi吧，因为这个指数跟百姓的生活息息相关。虽说dgp deflator 更能全面的表示价格变动。
