^There's also talk that the central banks may have finally realized their shit doesn't work. ECB and Japan running negative rates, hardcore QE. US holding QE, near zero rates. What do they get? Huge asset bubbles, shit real growth.
The fed is painfully aware of the mistake Greenspan made in keeping rates too low for too long. They may end up making a similar mistake but they won't end up making the same mistake. I've got to give Yellen more credit than that.
So far she's been right about keeping rates low to boost the participation rate. From Aug of '15 to now, the rate is up almost a half of a percentage point - despite the dip earlier in the summer -

But the closer we get to
NAIRU, the more the fed has to worry about wage inflation, which we've already seen in some sectors. There's also the credibility issue you've pointed out. With a predicted 4 rate hikes this year, it's almost de rigueur that we get at least one more this year. Although honestly, I don't think anyone expects one before the election.
shiller PE is still at 26 - i wouldn't be surprised if this moves down to 20 or 15 over the next 10 years, and would in fact be relieved
hence the predictions that US stock returns will only be about %1-2 real in the next decade
By Shiller you mean CAPE? I think that's based on historical averages and since the recession we've been pretty far from the mean in terms of those. With rates as low as they have been, very low returns can support pretty rich valuations. Hopefully that's not going to follow Japan's lead where this goes on indefinitely.
Govts around the world are starting to realize that you need to have a fiscal component to support your monetary policy. One w/o the other can only do so much. Hence the concept of helicopter money. But I don't think we need to go to that extreme. Here in the US, we have plenty of work to do on infrastructure and a new building boom like we saw in the 50's with the interstate highway program would not only serve to revamp our wobbly infrastructure but give give the economy the shot of intravenous meth it needs.
