Is there a reason you can't access a price index? I'm not sure it is possible without a price index.

My professor has told me I don't need one. As far as I can tell I need the average growth rate and the real gdp. I'm just unsure on how to proceed from there.

If you have real GDP and nominal GDP, you can divide nominal by real to get a price index known as the GDP deflator.

The two series I have to use are:

Canada; Chained (2002) dollars (Dollars); Seasonally adjusted at annual rates; Gross domestic product (GDP) at market prices *Terminated*and

(Asked by: username_0 on 2015-06-01)

I have quarterly data for real GDP from 1981-2015. I also have quarterly chained-dollar real GDP from 61-2012. I need to have them converted into one series.

I've looked up several different formulas but most of them require a price index. Any help would be appreciated. Thanks.
