先週のFOMCを前にして、サマーズがWaPoFT自ブログに「Groundhog Day at Fed June meeting」というエントリを上げている(ただしWaPoの記事のタイトルは「The Fed is making the same mistakes over and over again」、H/T 本石町日記さんツイート)。

Japan’s essential macroeconomic problem is no longer lack out output growth. Unemployment is low. Relative to its shrinking labor force, output growth is adequate by contemporary standards. Japan’s problem is that it seems incapable of achieving a 2 percent inflation. This makes it much harder to deal with debt problems and leaves the Japanese with little spare powder if a recession comes.
I am reluctantly coming to the conclusion that the United States may be on a slow-motion trajectory towards a Japanese chronic lowflationary or even deflationary outcome. A corollary of this view is that the current hawkish inclination of the Fed, with its chronic hope and belief that conditions will soon permit interest rate increases, is misguided. The greater danger is of too little rather than too much demand. A new Fed paradigm is therefore in order.

Embedded inflation expectations are low and declining. Comprehensive measures of the labor market are deteriorating and growth is at best mediocre. Meanwhile inflation is clearly below where the Fed should want it. The right concern for the Fed now should be to signal its commitment to accelerating growth and avoiding a return to recession, even at some cost in terms of other risks.
This is not the Fed’s policy posture. Watching the Fed over the last year there is a Groundhog Day aspect. One senses they really want to raise rates and achieve a more “normal” stance. But at the same time they do not want to tighten when the economy may be slowing or create financial turmoil. So they keep holding out the prospect of future rate increases and then find themselves unable to deliver. But they always revert to holding out the prospect of rate increases soon, partly for internal comity and partly to preserve optionality.
Over the last 12 months nominal GDP has risen at a rate of only 3.3 percent. We hardly seem in danger of demand running away. Today we learned that Germany has followed Japan into negative 10 year rates. We are only one recession away from joining the club. The Fed should be clear now that its priority is not preventing a small step up in inflation, which in fact should be welcomed, or returning interest rates to what would have been normal to a world gone by. Instead the Fed should focus on assuring adequate growth in both real and nominal incomes going forward.
