Baseline tuning

baseline_tuning selects model-data operations used to tune the baseline. It can configure:

• real interest rates in the base year; and
• monetary-policy adjustments.

Three cases are important:

YAML	Meaning
no baseline_tuning section	No tuning operation is configured
a defaults operation	Applies to every region not named in region_overrides
a region_overrides operation	Completely replaces the default for that region

An override is never a partial amendment. It must contain every field needed by its selected adjustment method or transition.

Configure both tuning operations

baseline_tuning:
  real_interest_rates_in_base_year:
    propagation:
      other_domestic_nominal_price_indices: true
      wages: true
    defaults:
      adjustment_method: range
      floor_real_interest_rate: 0.0
      ceiling_real_interest_rate: 7.5

  monetary_policy_adjustments:
    projections_file_name: baseline_INTX_projections.csv
    defaults:
      start_year: 2023
      end_year: 2030
      annual_decay_percent: 50.0

The YAML selects the economic operations. The maintained python/update_model_data.py script separately chooses whether each operation is disabled, shown as a summary, or applied with apply.
