Nevertheless, its core insights regarding the importance of stabilizing nominal aggregates and the limits of policy remain central to the consensus view of how advanced economies should be managed by central banks and treasury departments. 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 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. Critics argue that its focus on demand-side frictions sometimes downplays supply-side shocks and the real effects of financial frictions.
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. New Keynesian economics emerged as the primary theoretical framework for understanding modern macroeconomic policy, offering a rigorous justification for government intervention during periods of sluggish demand.

Microfoundations: Replacing aggregate equations with explicit household and firm behavior. 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.
