Hello,

I am trying to merge a data set with Compustat/CRSP by company name since there is no common identifier between these two data sets. The data I am trying to match has no cusip or cik. I have matched the company names using an algorithm in SAS and have manually checked whether the matched companies are really the same company.

The next step I want to do is to check whether the unmatched observations are subsidiaries of another publicly traded company. The data is panel and is from 1977 to 2009. I am using Million Dollar Database of Mergent to do this, but the problem is that I can only see the current information of a company in the database. I am wondering is there any database available that I can check the subsidiary status of a company for a given year?

Thank you very much!!!

Best,

stupidstudent
