Janet Yellen has essentially confirmed QE’s demise; good riddance. Unfortunately, I don’t think that is the final end of QE in America, just as it hasn’t been the end time after time in Japan (and perhaps now Europe treading down the same ill-received road). The secular stagnation theory, that we think has been fully absorbed in certainly Yellen’s FOMC, sees little gain from it because, as they assume, the lackluster economy is due to this mysterious decline in the “natural rate of interest.” Therefore QE in the fourth iteration accomplishes far less toward that goal, especially with diminishing impacts on expectations in the real economy, other than create bubbles of activity (“reach for yield”) that always end badly. What Krugman and Summers call for is a massive bubble of biblical proportions that “shocks” the economy out of this mysterious rut, to “push inflation substantially higher, and keep it there.” In other words, Abenomics in America. Japanification is becoming universal, and the more these appeals to generic activity and waste continue, the tighter its “mysterious” grip.
