Law of Motion for Inflation: An Analogy to Newtonian Mechanics

Taiji Harashima

MPRA Paper from University Library of Munich, Germany

Abstract: This paper proposes that inflation dynamics follow a law of motion analogous to Newtonian mechanics, driven by a "repulsive force" between the government and households. While the government attempts to manipulate the real interest rate toward its preferred level, households resist to maintain their own, resulting in a strategic tug-of-war. The study demonstrates how this force-based inflationary motion mirrors Newtonian laws—specifically inertia, acceleration, and action-reaction. Additionally, the concept of kinetic energy is employed to analyze central bank strategies for achieving price stability.
