## In authors' words

### What they found (results)

A Bayesian dynamic-threshold model of Nigeria (1990-2025) found the inflation threshold averages about 33.6%, with currency depreciation showing no significant relationship to inflation below that threshold but a large, positive effect above it.

## Commentary

### In short

Which side of a distinction (above vs. below an inflation threshold) a system sits on determines whether one variable (currency depreciation) affects another (inflation) at all — the relationship only exists on one side of the boundary.
