After a year, we present another in a series of adjustments and partial extensions to the core prediction model g3+[1], reflecting economic developments and experience with its use. Using the current extended version of the g3+ model, the shadow forecast presented in this appendix was prepared. The purpose of the shadow forecast is not to capture specific risks of the baseline scenario of the ZoMP winter 2025, but to present the extended version of the g3+ model, its benefits and specifics. From this spring's Monetary Policy Report, this extended model will become the main prediction tool of the CNB.
