Question

I have the GDP deflator for country X from year 1980-2005, with 1990 as the base year. My question is how can I change the base year, for instance to change it be year 2000?

Thank you,

Here is sample:

Delfators:

Year Base=1995 Base=1998 ... Calculation

1995 .. 100 ........ 93.4579 ...... 100*100/107=93.4579

1996 .. 102 ........ 95.3271 ...... 102*100/107=95.3271

1997 .. 104 ........ 97.1963 ...... 104*100/107=97.1963

1998 .. 107 ....... 100.0000 ...... 107*100/107=100.0000

1999 .. 110 ....... 102.8037 ...... 110*100/107=102.8037

2000 .. 114 ....... 106.5421 ...... 114*100/107=106.5421

So just multiply by 100 (depending on representation) and divide by desired new base year delfator.
