Hi everyone,

I am new to CRSP so I hope someone can help me out here.

I need to obtain the age of certain firms from CRSP.

The paper I follow states “Firm age is constructed as the number of years the firm has existed on the CRSP database.”. However, I am not sure how to get this from CRSP.

Can anyone please please help me out.

I will be grateful forever

Thanks,
Milica
