Hi XXX,

Attached is a version of the fluidity data that includes self fluidity.  We generally advocate using the product market fluidity variable, as explained in the paper but we 
agree that self fluidity can be relevant for some unique research projects.

Note that for some observations, self fludity is missing even though the observation has product market fluidity.  This is b/c self fluidity requires available 10-Ks two years in a row whereas you only need the current year to compute product market fluidity.

We appreciate the interest in this work.  Best wishes with your research!

Sincerely,
Jerry
