Amity Shlaes....
She stole my heart with her intellect and writing savvy alone. : )
That story/study is 7 years old. An oldy, but a damn goody. I always love to pull that sucker out in online debates.
They also did one for Hoover, which goes right along with her book: http://newsroom.ucla.edu/portal/ucla/pandering-to-labor-caused-great-91447.aspx
(I don’t remember the above link/article being from 2009, I thought it came out around the same time the FDR study came out, but who knows.)
they first reported this, off the top of my head, in early 2000’s.
there’s a citation concerning them in 2004:

amity schael’s book came out in 2007.
