Labor Market Imperfections: Including unemployment insurance and search frictions that influence wage setting. Firms face costs when changing prices, such as menu costs or the hassle of frequent adjustments, leading to sustained deviations from marginal cost.
New Keynesian Modern Research Insights: Labor Market Imperfections and Pricing Frictions
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. 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.

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.
