A simple measure of Fisherian amplification with flow collateral constraints

Eugenio Rojas and Felipe Saffie

Economics Letters, 2025, vol. 255, issue C

Abstract: We derive a closed-form expression for Fisherian amplification in small open economies. The formula isolates nonlinear feedback from price-sensitive collateral and highlights when macroprudential concerns become relevant due to amplification driven by collateral tightness and substitution elasticity.
