Lagging Indicators
Forecasts have become a favorite pastime of economists of all stripes. Not a week goes by without some eminent organization coming up with an even-darker prediction for growth in 2009 (and lately, 2010). The IMF has been a clear leader in updating its forecasts, doing so every second month since September. Some commercial banks - the same who entirely missed the crisis onset - are now competing for the gloomiest forecast. Why is this happening?
Well, the severity of the crisis is deeper than anyone expected, so some updating is natural. But when does is become clear that forecasters are simply running behind the news? To me, this is clear now. Here is my prediction: we will have another 2-3 rounds of gloomier forecasts, at which points some signs of recovery will show up and the forecasters will start "upgrading." And once upgrades come, there will be an avalanche of those.
To keep your sanity, don't follow forecasts closely. Instead, what can be more useful for policymakers and business people is to use scenarios. Say, a low, middle and high scenario. Then simulate what you would do if the world enters any of these scenarios. This is more fun, and at this point provides more useful information than any single forecast.
