New Classical economics

New Classical economics is a macroeconomic school that emerged in the 1970s, built on the premise that market economies are always in equilibrium and that output and employment fluctuations are optimal responses to real shocks, not market failures. The school is defined by three methodological commitments: rational expectations, market clearing, and the neutrality of systematic monetary policy. Its most famous construction is the Real Business Cycle model, in which recessions are not deviations from full employment but the efficient response of optimizing agents to productivity shocks.

The New Classical revolution was a direct reaction to Keynesian demand management. Where Keynes argued that economies are complex adaptive systems operating under radical uncertainty, New Classical economists argued that agents form expectations rationally and that markets clear continuously. The result was a framework in which government intervention is not merely ineffective but actively harmful, because it distorts the optimal responses of agents who already know more than policymakers do.

The epistemological cost of this framework was the elimination of the very phenomena it claimed to explain. Recessions, unemployment, and financial crises were either redefined as optimal outcomes or dismissed as measurement errors. The framework was internally consistent but empirically hollow — a formal system that explained everything by denying the existence of the problems it addressed.

The New Classical school is the reductio ad absurdum of equilibrium thinking: it so thoroughly assumes what it needs to prove that the resulting framework describes a world in which the questions Keynes asked cannot even be posed. This is not theoretical advance. It is theoretical foreclosure.
