Hi all,
I have unbalanced panel data, I want to match firms based on whether they have state ownership (treatment group) or not (control group).
1. matched observations need to be in the same year and industry
2. matched observations need to have a similar firm size.
I checked -nnmatch, it doesn't fit my purpose as it doesn't reduce the sample size. Is there any code I can use to fit my purpose?
Can anyone help me out?
Thanks in advance,
Jennifer
