Hi- I am looking for a code that can match panel data with years and industry only for pre- period. My modal is DID Y=post*mandatory +Fixed effects.
Mandatory is a dummy =1 or 0 represents my control and treatment (treatment is 1). Post is a dummy equals 1 after event.
This is a panel data with 37 firms as treatment (mandatory=1).
I need to match on pre- period based on variables "before_after_event years" (that is all years between (-1)-(-4)) and "SIC_2digit".
the propensity should be run on variables "E", "leverage" and "AT".
1. I try to find a code but didn't see anything that can work.
2.When "before_after_event years" is >= o , I do not need to match anymore- how can I build my sample for that? the pre- should be match but the post does not?
3. I prefer to do not loose treatment firms
Best,
HB
Can you post what code you tried and what did not work. As well as a sample of expected output.
@HEB1 What were you trying to do with that code you posted? I do not see how it is related to your objective or the data you provided. It will be tricky to give a solution without details of what is not working in code you've tried, and an output example.
Also, when you post SAS code, use use the "little running man" button.
