More on monetary policy

Matt Nolan blogs:

at heart isn’t about “unemployment” or “output” or “the exchange rate” (which is a relative price).  is about money, it is about the supply of money, it is about the price level and inflation.  The “interest rate” is merely an instrument central banks use to control the money supply and keep “inflation stable”.  By keeping inflation stable we increase certainty and we help make sure that money remains a good indicator of the relative value of REAL goods and services.

The idea that we should mess around with this to tinker with other things misses the point – if our exchange rate is funny, unemployment is high, or output is below potential we have to ask “what issues in REAL economy are causing this”.  Monetary policy in itself is irrelevant – monetary policy IS about money, it IS about inflation, it IS about expectations regarding these nominal variables, it IS NOT about real economic variables.

I am not saying that monetary policy hasn’t moved real variables – but in a world where monetary policy IS solely focused on inflation and consistent expectations is a world where monetary policies impact on the real economy is at its best.

It worries me greatly that Labour have abandoned support for a bipartisan monetary policy consensus.
