Nice article and nice blog! Happy to find that someone built a similar blog.
When I was processing ExecuComp data, I realized that it is hard to identify CFOs. We cannot use CFO flag to identify a CFO because this variable has too many errors. Also, Jiang et al.’s (2010) method is not perfect because it leaves many duplicated observations, or say we will see one firm may have two or three CFOs.
The identification method in this article is too preliminary and do you have a better way to identify CFOs?
