Please accept my apologies. I will in time be publishing the full analysis and advocacy in wiki form (so as to update it, and invite comments), but for now I hope this link to the google document will suffice.
A note for journalists forwarded to this site by the IPPR. There are a couple of editorial slipups in the article I had published in Public Policy Research which have thus far regrettably coloured the kind of feedback it has received. Needless to say, I will be happy to provide an earlier, more thorough draft on request. Mail firstname.lastname@example.org and I'll send it on.
