Narayana Kocherlakota makes it clear that the rate at which the recovery is proceeding is just fine with him. No more accommodation from the Fed is necessary given that "Since November, inflation has risen and unemployment has fallen."
But he doesn't acknowledge that the November date is cherry-picked to some extent. Since January -- just two months from when he starts his measurement -- unemployment has actually risen. He's happy with that? As for inflation -- the worry that is stopping him from endorsing a more aggressive policy -- using his preferred time period from last November until now, core PCE has risen from 1.0% to 1.3%. And it didn't move at all between May and June, it was 1.3% in both months. Uh oh, hyperinflation! Assuming a target of 2.0%, at this rate the Fed will reach it's inflation target in about a year and a half. Sounds kind of like the guidance they issued (and there is a good argument that the Fed should overshoot its target in the short-run). Perhaps lag effects can explain his response, if we tighten now we may not feel it until a year later, but that doesn't seem to be his argument:
In its August 9 meeting, the Committee changed this “extended period” language to say instead that it “currently anticipates economic conditions … are likely to warrant extraordinarily low levels of the federal funds rate through mid-2013.” This statement is designed to let the public know that the fed funds rate is likely to stay between 0 and 25 basis points over the next two years, not just over the next three to six months. Hence, the new language is intended to provide more monetary accommodation than before.
I dissented from this change in language because the evolution of macroeconomic data did not reflect a need to make monetary policy more accommodative than in November 2010. In particular, personal consumption expenditure (PCE) inflation rose notably in the first half of 2011, whether or not one includes food and energy. At the same time, while unemployment does remain disturbingly high, it has fallen since November. I can summarize my reasoning as follows. I believe that in November, the Committee judiciously chose a level of accommodation that was well calibrated for the prevailing economic conditions. Since November, inflation has risen and unemployment has fallen. I do not believe that providing more accommodation—easing monetary policy—is the appropriate response to these changes in the economy.
Again, "well-calibrated" should include both the direction and pace of change. Even if the direction is correct, is he satisfied with the pace of change for employment? I realize he thinks we will have to tighten in 3-6 months, but it's hard to see how a data-based projection takes you to this outcome (even more so if you believe, as I do, that the risks are asymmetric, i.e. that unemployment is more costly than inflation).
Finally, this is not a rock solid commitment from the Fed. This is their view of the most likely path for the federal funds rate, they have not said this is what they will do independent of how the data evolve. All they have said is that economic conditions are likely to warrant this outcome. The dissenters seem to believe that another outcome is more likely, the view is that economic conditions will force the Fed into a different posture -- you know, that high inflation and rapid recovery we've been seeing to date -- in as soon as 3-6 months. Anything is possible, but again, it's hard to see how recent data point to this outcome.
