Dear Statalisters:

I have two variables V1 and V2 for 5 years: 2001, 2002, 2003, 2004 and
2005 (in total 1344 observations).

My assumption is that the growth rate of V1 over the period (from 2001
to 2005) is higher than the growth rate of V2.

Do you know a statistical tool to test this difference in growth rates?
I would also like to make this test for several periods (for example
over one year from 2003 to 2004, or over two years, etc.).

Best regards

Hervé Stolowy
