Hi,
I have two samples. Sample 1 (main sample) includes 200 companies from Sweden. Sample 2 includes 5000 companies from the US. Using sample 2, I want to find one match company for each company includes in sample 1. I want to find my match sample based on sic code (company industry identity), assets (company's assets value), ROA and audit fees.
All the companies are identified by a specific identity number, ISIN number. Both samples show the variables: sic code, year, assets, ROA and audit fees.

I would be grateful if one could help me that how can I find the match based on the several variables or criteria.

Note:
I am using mac and Stata 15.

Best regards,
Mahmoud
