Research in this area appears to go back to at least the 70's.
At one occasion he calls it a controversy himself:

E. Wolf, "The Redshift Controversy and Correlation-induced Spectral 
Changes", in Waves, Information and Foundations of Physics (Italian Physical 
Society, Bologna, Italy), R. Pratesi and L. Ronchi, eds., Conference 
Proceedings vol. 60 (1998), 41-49.

You can order these proceedings here:
http://www.sif.it/SIF/en/portal/books/series/conferenceproceedings for about 
$100.

A cheaper single article on the subject can be obtained here:
http://www.iop.org/EJ/abstract/0034-4885/59/6/002 for $80

Maybe you can find some info for free by googling on: correlation induced 
doppler
