Dear Statalist members,
I am trying to run a coarsened exact matching to create comparable pair of individuals within my sample.
In summary, I need to match an employees that leaves a firm with another employees within the same firm on several characteristics. So, the treatment is leaving the firm or not (0 or 1).
I am trying to performe the matching in the following way:
cem firm_id(#0) experience(#5) salary(#5), treatment(leave)
I am trying to first coarse the matching only within the individuals that belong to the same firm (have the same firm_id). However, After the matching I observe that although most of the control group that was generated (matched) belongs to the same firm, some observations do not.
Would someone have a suggestion on how I could set the program to first perform an exact matching on firm_id and then match on the addition characteristics?
Best,
Alexander
