Firms face costs when changing prices, such as menu costs or the hassle of frequent adjustments, leading to sustained deviations from marginal cost. The school’s research on optimal policy rules, such as the Taylor rule, has evolved to incorporate these constraints, emphasizing the need for higher inflation targets or fiscal-monetary coordination to maintain stability when the policy space is exhausted.

This stickiness is crucial for transmitting demand shocks into real economic variables like output and employment. The size of this multiplier depends critically on the state of the economy, the persistence of the shock, and the specific composition of government spending, making empirical estimation a central concern.
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.

New Keynesian Expectations Forward Guidance and Modern Policy Frameworks
When monetary policy is constrained, government spending can have a significant multiplier effect on aggregate demand, as idle resources are put to use without crowding out private investment. Critics argue that its focus on demand-side frictions sometimes downplays supply-side shocks and the real effects of financial frictions.
