Inflation, Inflation… There is No Inflation
I want to clarify since I always feel a bit dirty after doing pessimistic posts about the supply-side:
1) I have very low confidence in any views about “potential output” and whether the productivity data is “correct”. That is doubly true for my own half-baked views.
2) I think the productivity data should have a 0% weight in setting monetary policy. Zero, zip, nada, zilch. And I think nominal wages
and/or incomes should have a 100% weight.
It is this second point which made me particularly angry at Carney’s (latest) hawkish move: the new data this year is telling us that nominal wage inflation is at record lows. Hence we need tighter monetary policy because…? Well, it’s not clear.
It is half true that the UK is looking more like Japan in 2014 than ever before. The CPI rate is below target and now looking kind of “low“. Nominal wage growth is dead. Tax revenues are sluggish; there is a gigantic fiscal deficit and public sector debt is heading up to the moon. The currency is looking pretty strong – something which plagued pre-Abe Japan regularly. Almost everybody is a supply-side pessimist. Our central bankers are hawkish. And even Her Majesty’s Loyal Opposition has been campaigning on the basis that “prices are too high”. (Maybe Ed Balls read all the Japan ZLB literature sitting on his head?)
But that is not the whole picture. I still don’t see any convincing sign that nominal GDP growth is slowing from around 4-5% y/y, a rate which should normally be consistent with the Bank’s mandate. The “low CPI rate” today is as useless a demand-side indicator as the 5.2% CPI rate was in September of 2008 or 2011. Inflation expectations are very stable and consistent with hitting that 2%. Confidence indicators are at multi-decade highs. I think “steady as she goes” would be a pretty reasonable monetary policy if you do want to take the inflation target seriously.
