`   ==Concerns over Tom Walker== A full two paragraphs is spent discussing Tom Walker's ``rebutal`` of the relatively common position that work-week restrictions are not effective against unemployment.  I was instantly left wondering, who is Tom Walker.   Tom walker turns out to be a social policy activist   (Yes, I'm pretty sure I have the right Tom Walker).  His rebutal has not to my knowledge been published in a peer reviewed journaland my opinion, as a PhD candidate, is that it is riddled with enough errors of logic as to not even merit consideration as reasonable dissent.  Unfortunately, Mr. Walker is so obscure, I can't find anyone who has taken the time to critique him in a peer reviewed journal eitherwhich isn't surprising given that his paper was never published in an accepted journal.  As much as I'd like to include some real argument against the commonly held position of economists, I don't think this Tom Walker stuff passes muster to merit inclusion.  I intend to delete the paragraphs relating to him.  I invite people to come forward with information suggesting that * Tom Walker is actually a figure of merit, qualified to have so much prominence in this article. * has published his rebutal in a generally accepted peer reviewed journal Also, if people have any replacement suggestions.  Please speak-up.   `
