Dear Stata users,
I am using propensity score matching estimator to find matched exporters and domestic firms, and estimate the sales differences between them.
However, I not sure how to restrict matched exporter and domestic firms in the same industry and same year in the matching exercise? I want to match an exporter A with domestic firm B who have smallest propensity score difference and they have to be in same industry and appear in the same year.
Do you have any suggestion on this ?
Best regards
Yong
