Macroeconomics Schools

Macro schools disagree about the mechanism, not just the policy preference. Use this page to see which assumptions each tradition starts from, where it breaks with others, and which models carry the argument.

Reading guide

Ask what each school thinks failed first

Then check the evidence it would need: demand data, monetary aggregates, expectations, price rigidities, credit conditions, institutions, or power

Mainstream split

Same data, different failure point

Mechanism

Demand shortfalls cause recessions; fiscal and monetary policy should actively stabilize the economy

Dispute

Demand management versus nominal-anchor discipline; Persistent demand failure versus fast expectation-led adjustment

Mechanism

Inflation is primarily a monetary phenomenon; stable money-supply growth matters more than fine-tuned intervention

Dispute

Demand management versus nominal-anchor discipline

Mechanism

Markets clear more quickly than Keynesians allow, and systematic policy has little room to surprise the economy into producing more

Dispute

Persistent demand failure versus fast expectation-led adjustment; Nominal rigidities and imperfect competition versus near-frictionless clearing; Power, institutions, money creation, and distribution belong inside the model

Mechanism

Markets are forward-looking but still imperfect; sticky prices and wages give policy real short-run effects

Dispute

Nominal rigidities and imperfect competition versus near-frictionless clearing
