I think the association of economics with forecasting is unfortunate and is down to the fact that one great way to get an investment bank's name on business television is to hire a guy called a Chief Economist who will go and prognosticate.
I never understand why 'economist makes forecast' is ever a headline. Whether the economist in question is from the International Monetary Fund, a City forecasting group or the Treasury - a forecast is still not news.
There is much more to life than what gets measured in accounts. Even economists know that.
