• Supply Shocks in the Fog: The Role of Endogenous Uncertainty

  Staff working paper 2026-12 Anastasiia Antonova, Mykhailo Matvieiev, Celine Poilly

This demand channel can overturn the inflationary impact of negative supply shocks, making them deflationary, unless monetary policy stabilizes the output gap.
