Measuring the Cost of Regulation: A Text-Based Approach

We derive a measure of firm-level regulatory costs from the text of corporate earnings calls. We then use this measure to study the effect of regulation on companies’ operating fundamentals and cost of capital. We find that higher regulatory cost results in slower sales growth, an effect which is mitigated for large firms. Furthermore, we find a one-standard deviation increase in our preferred measure of regulatory cost is associated with an increase in firms’ cost of capital of close to 3% per year. These findings suggest that regulatory risk is a major cost to firms, but the largest firms are able to manage that risk better.

That is the abstract of a new NBER paper by Charles W. Calomiris, Harry Mamaysky, Ruoke Yang, a piece written in pre-Covid-19 times.  It has never been more relevant, except that the estimates for regulatory costs turn out to be far too low (no criticism of the authors is intended here).  To repeat my earlier point, America’s regulatory state is failing us.
