st: Panel data using difference in difference with regard to reference yea

["sebastian.blesse" <sebastianblesse2404@gmail.com>]

Hello Statlistusers,

my problem is the following: I have a panel (from 1999 to 2005, observations
are 410) over municipal expenditure data and several controls and i want to
run a difference in difference estimation on the expenditure impacts of a
reform taken place between 2000 and 2003. The only year available before the
reform was 1999 and i want to compare this to the after reform years 2004
and 2005. Hence, for Diff in Diff on total expenditures (totexp_pc) i want
to compare the values from 2000 with those of 1999 as the reference year. I
just dont know how to formulate this in STATA. 

Here is a list of my variables with description for better understanding:

 id - Code of municipality
year - year
amalg - participation variable
 pop
 area
popdens
 unemplrate
 gdp_pc
 capitalregion
 staffexp_pc
 interestexp_pc
 adminexp_pc
 totexp_pc
 grants_pc
 budgetsurplus_pc
 fiscalpressure_pc
 totrevenues_pc
 currentexp_pc
 popsquare 
usearea_pc
 births_pthc 
immigration_pthc
 young_pthc
 old_pthc 
netimmigration_pthc

Kind regards,

Sebastian Blesse
