Bank economists main perogetive is to there traders, so I assume that there discussion will be significantly stronger when talking to what is effectively their client base. When it comes to releasing reports like this it is important to remember that it often functions as advertising – so they are just trying to give a generic, and sometimes yes meaningless, discussion.

Also it is important to try and remember what we mean when we say economists forecast accuracy is not important – we are not saying that the art of forecasting isn’t important, just that it is incomplete. The value should come through the discussion regarding risks and the pointing out of important factors – rather than a blind reliance on figures.

For example, take this pearler from ANZ’s report this week: “We will need to see the experienced trading activity measure catch-up to the expected reading before we can grow more confident that a full blown recovery is underway.” In other words, “we need to see the recovery confirmed before we can confirm the recovery”. If that’s all you have to say, why not just become a reporter? Oh, right, the salary difference.

That is very true Hone.

I find it runs even deeper than that for some areas that are placed in the branch of science – eg nutritionists. Often they do not properly show causation, do not include obvious exogenous variables, and do nothing about endogeniety – and yet a lot of their work is shown as “truth about food”. It irks me, and a number of health professionals I know ๐Ÿ˜›

Should we lose faith in medical science because it did not forecast swine flu? Are climatologists out of touch because their models vary and they can’t forecast the weather? Is forensic science in terrible trouble due to type II errors on DNA tests in murder cases?

For Mankiw to see the headline in an RSS he would have to subscribe – I have no doubt that he would never subscribe to this blog ๐Ÿ˜€
