Just spotted a rather silly mistake in what I've written above:

Where I said:
So if inflation gets too high, the government has several choices: put more money into the economy, take more money out of the economy (via taxation) or use interest rates to influence private spending and investment decisions...

What I meant was:
So if inflation gets too high, the government has several choices: put LESS money into the economy, take more money out of the economy (via taxation) or use interest rates to influence private spending and investment decisions....

From the context (and the lack of responses) I hope it was obvious that I thought one thing and wrote the opposite. But as there are some people here who think I believe silly things about economics, I thought I'd better not leave this uncorrected.
