The Long and Short of It at Goldman Sachs - New York Times: So I started an e-mail correspondence with Dr. Hatzius, pointing out what I believed were a few flaws in his paper. Among them were his hypothesis that home prices would fall an average of 15 percent nationwide (an event that has never happened since the Depression, although we surely could be headed in that direction), and that this would lead to a drastic increase in defaults and losses by lenders.
This, as I see it, is a conclusion that is an estimation based upon a guess. I found especially puzzling the omission of the highly likely truth that the Fed would step in to replenish financial institutions’ liquidity if necessary. In a crisis like that outlined by the good Dr. Hatzius, the Fed — any postwar Fed except perhaps that of a fool — would pump cash into the system to keep lending on track.
