1. Figure 1. Minimum distance characteristics of fitted TPN and WSN distributions to U-uncertainties
WSN fits better than TPN, especially for medium and long horizons.
2. Figure 2. Term structure of the compound strength of forecast-induced monetary policy
The compound strength is computed as: , where
. In the policy-input symmetric case, where
(and this is the assumption applied for empirical estimation), the multipliers
can be ignored.
