Man Bites Dog! Regulatory Edition

I woke up this morning to see an abstract of a paper entitled Is Regulation to Blame for the Decline in American Entrepreneurship? When I saw that one of the co-authors was on the George Mason University economics faculty, I said to myself, "Well I know how this plays out."  But then I read the abstract, which concludes:  "Federal regulation has had little to no effect on declining dynamism." 

I wonder what the same commentators who trumpeted the "Dodd-Frank is killing community banks" stuff will think of this paper. I'm personally skeptical that one can measure the stringency of regulation in any quantifiable way, much less for different industries, but I'll just flag that this paper is out there.
