Hello,

I have a "CEO" variable for firms on panel data and the CEO names are not inputted the same due to spelling errors. For example, it can be "Jaeyoung Song" for one year and "Jaeyong Song" for another year. I hope to make the information to be consistent despite the typos. Also, other times, it is spelled as "Song Jaeyoung" instead of "Jaeyoung Song" due to first-last name ordering differences in other countries than the US. Is there any way that I can match them and give the same values to these names?

Ultimately, I hope to give the same values for the same CEO of the same firm ID. Let's say

Firm 1 has years from 1992-2000 and its CEO has changed as follows:
1992 Jaeyoung Song
1993 Jaeyoung Song
1994 Jaeyong Song
1995 Song Jaeyoung
1996 Taeho Kim
1997 Taeho Kim
1998 Sunhwa Han
1999 Sunha Han
2000 Sunhwa Han

Then CEO changes twice over the years and I hope to give the same CEO the same ID within the firm. Could you help me on how to match slightly different information and also give different values for different people within the same ID?

Thank you for your help in advance!
