Roy Weintraub's suggested lacuna of HET work on the NBER focuses on the last 25 years. However, I think the work of Malcolm Rutherford on the NBER, which is archivally based, deserves some mention. Admittedly, my impression is that Rutherford's work focuses on NBER pre-Feldstein, but my recollection is that he has given some attention to the transition from the John Meyer era at NBER to that of Feldstein. Two pieces on NBER currently listed on Malcolm Rutherford's website are: "'Who's Afraid of Arthur Burns?' The NBER and the Foundation," Journal of the History of Economic Thought, June, 2005, Vol.27: 109-139 and an entry on "NBER" in the New Palgrave 2nd edition forthcoming 2008. I certainly would not disagree with Roy Weintraub's suggestion that there is fruitful work to be done on the more recent history of the NBER. But I do think work on the earlier history of the NBER should be acknowledged. David Mitch
