Well, first let me say that I completely agree with you -- the Fed must do its fucking job. But there problems:
1) The Fed does not do its fucking job. And, as Mankiw has put it, "If Chairman Bernanke ever suggested increasing inflation to, say, 4 percent, he would quickly return to being Professor Bernanke".
2) Why it has to be either stimulus, or inflation? And what if 4% inflation is not enough?
First off, the entire point of an independent central bank is that they're supposed to be insulated from that kind of political pressure.
Second, you don't have to raise the inflation target. I was talking about targeting the
level. Specifically, targeting the level of nominal spending; which Krugman, among many others, have recently endorsed. We don't need to increase target
rate of inflation, just return the
level of nominal income back near its pre-recession trend line.
But, again, I agree completely -- 2% inflation is simply too low. This is not the first time we at zero lower bound. But since we are at 2%, we are in the liquidity trap.
Right but the point is that there's no such thing as "the liquidity trap". To quote Ben Bernanke, it's a "self-induced paralysis". It's not that monetary policy can't be expansionary at the zero lower bound, it's that the central bank is
unwilling to engage in expansionary monetary policy.
Again, Krugman is in favour of NGDP level targeting. Yet he's still thrashing the point about fiscal stimulus. Does it make any sense to you (it certainly doesn't to me) that he insists on advocating fiscal stimulus? Fiscal stimulus requires the government to take consolidated action
every time there is a recession. Congress has to agree on and successfully pass a stimulus package
every recession. With NGDPLT, congress just has to pass an amendment to the Federal Reserve Act once, changing the Fed's mandate. In fact, the Fed can adopt level targeting voluntarily, but so far they're clearly unwilling to take necessary action. So if congress has to do something, isn't it clearly better to have them do the thing that only requires them to cooperate once?
