3. The Accuracy Problem
The content discusses the problems with macroeconomic forecasting, particularly the lack of predictive accuracy in recent years. It highlights that准则 models are very accurate at predicting recessions, but the underlying mechanisms driving economic slowdowns into projections that further delay.
4. The Direction of Causality Problem
