Richard Fisher of Dallas Fed is has given yet another superb speech. He starts by giving some basic lessons on macroeconomics and says why Central Bank independence is very important.
He defends his dissent to the rate cut by Fed pretty well:
Monetary policy acts with a lag. I liken it to a good single malt whiskey or perhaps truly great tequila: It takes time before you feel its full effect. The Fed has to be very careful now to add just the right amount of stimulus to the punchbowl without mixing in the potential to juice up inflation once the effect of the new punch kicks in.
……My dissenting vote last week was simply a difference of opinion about how far and how fast we might re-spike the monetary punchbowl. Given that I had yet to see a mitigation in inflation and inflationary expectations from their current high levels, and that I believed the steps we had already taken would be helpful in mitigating the downside risk to growth once they took full effect, I simply did not feel it was the proper time to support additional monetary accommodation.
Read the speech for humour and some excellent analogies.
