New classical macroeconomics is a school built on neoclassical foundations that assumes economic agents form rational expectations and that markets clear continuously, so the economy tends to a unique full-employment equilibrium through price and wage adjustment. It emerged in the 1970s, led by Robert Lucas Jr., whose Lucas critique argued that Keynesian macro-econometric models lacked the microeconomic foundations needed to predict how agents would actually respond to a policy change, and it gave rise to real business cycle theory, developed by Finn Kydland and Edward Prescott, which explains recessions as responses to real productivity shocks rather than demand failures.
Facts
Start YearSources date the school's emergence to the 1970s rather than to a single founding year. Core TenetBecause agents form rational expectations and markets clear continuously, only unanticipated shocks have real effects; systematic, anticipated government demand-management policy cannot durably move output or employment away from its equilibrium path. 1 Connections

Why this is disputed. New classical economists blamed 1970s stagflation on Keynesian demand-management policy, and Robert Lucas's Lucas critique argues Keynesian macro-econometric models lack the microeconomic foundations needed to predict how agents actually respond to a policy change.

Why this is disputed. New Classical economists, Robert Lucas Jr. and Thomas Sargent chief among them, argued the synthesis' own theoretical foundations were fundamentally flawed because it lacked rational expectations, a critique the 1970s stagflation evidence appeared to vindicate.

Critiqued Here
Why this is disputed. Both schools share the rational-expectations toolkit; the live dispute is whether markets clear continuously through flexible prices (New Classical) or only gradually because of sticky prices and wages from imperfect competition (New Keynesian), a difference with directly opposed policy implications for whether stabilization policy can work.

Sargent highly criticized the theory, claiming that predictions [based on this theory] were widely incorrect, and "that the doctrine on which they were based was fundamentally flawed is now a simple matter of fact".
