I picked this study up from Mark Thoma's blog. FWIW, Dean Baker (founder of the CEPR and author of the paper here) has a well-established record as an economist and his credentials can be looked up.
I'm not sure what your implication is, though. Are you afraid of a liberal bias, conservative bias, pro-capitalist or anti-capitalist bias?
If I posted a paper from the Quarterly Journal of Austrian Economics, I doubt that you would consider the "journal" part to be a consolation.
