Dear Stata Users. I have a stata file with several variables for 500
schools in years 2000-2009.
One of this variables is the monetary allocation each school received
for school lunch program.
What I need is to estimate the growth rate of the allocation received
each period, but I have no
idea how to do that.

I'm using Stata 10 and windows XP.

Example:

school_code      year   sch_lunch  growth
1                      2000    1200          na
2                      2000      300          na
1                      2001    1300          0.083
2                      2001      500          0.666, etc.

thanks for your help
