Brad Delong calls for economists to "mark their beliefs to market" - that is, reassess their position when the facts suggest that they might have been wrong - and commendably shows us the way here. He is also very hard on economists who fail to do so; I only wish the UK media would be equally critical of those whose analysis has proved wanting (I could suggest a few names..).
But I was talking about me, of course. I have just despatched my reply to the usual end-of-year email from Chris Giles at the FT asking for my economic predictions for 2013. You'll have to wait until very early next year to read them and those of others; but I thought it was worth looking back at what I said in December 2011 (to the FT and separately to the New Statesman), which I reproduced here at the time.
