Abstract
Purpose The purpose of this paper is to establish a link between inflation uncertainty and interest rates for five inflation‐targeting countries. Design/methodology/approach The approach takes the form of a time‐varying parameter model with a Generalized Autoregressive Conditional Heteroskedasticity (GARCH) specification, used to derive impulse uncertainty and structural uncertainty. Findings This study attempts to establish a link between inflation uncertainty and interest rates for five inflation‐targeting countries, i.e. Canada, Finland, Spain, Sweden, and the UK. Decomposing inflation uncertainty into two components – impulse and structural, a positive association was found between the expected inflation and interest rates. Structural uncertainty has a positive and significant effect on interest rates for some countries. It has also been found that the long‐run effects of inflation on interest rates are less than unity for the post‐inflation targeting period, which implies that in some respect the Central Bank has been successful in targeting inflation. This has allowed the Central Bank to employ a less restrictive monetary policy in an environment of a credible inflation‐targeting strategy. Research limitations/implications Exponential Generalized Autoregressive Conditional Heteroskedasticity (EGARCH) can be used instead of GARCH modelling. Originality/value This is the first study that has tried to establish the link between different types of inflation uncertainty and interest rates for the inflation‐targeting countries to see the effect of inflation targeting.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
