The most influential model capturing this is the New Keynesian Phillips Curve, which posits that current inflation depends on expected future inflation and the output gap, reflecting the pressure of aggregate demand on price setting.
Understanding New Keynesian Transmission Mechanisms
Firms face costs when changing prices, such as menu costs or the hassle of frequent adjustments, leading to sustained deviations from marginal cost. When a central bank credibly commits to keeping rates low until specific economic thresholds are met, it can influence long-term interest rates and current spending even when the nominal lower bound is not at zero.
The Core Mechanics of Price and Wage Rigidity The analytical engine of New Keynesian theory rests on the concept of nominal rigidities, primarily through monopolistic competition and staggered contract setting. Microfoundations: Replacing aggregate equations with explicit household and firm behavior.

Labor Market Imperfections: Including unemployment insurance and search frictions that influence wage setting. Monetary Policy in the Zero Lower Bound A defining policy challenge for New Keynesian analysis is the liquidity trap, where nominal interest rates approach the effective lower bound of zero.
