Study Notes
Traditional Keynesian Economics
- Stresses a fixed-price model, implying a horizontal aggregate supply curve.
- An increase in aggregate expenditure shifts the aggregate demand curve rightward, increasing real GDP.
- Believes wages are rigid, leading to small changes in prices and a flat aggregate supply curve.
- Advocates for active government intervention to restore economic equilibrium.
- Economic equilibrium is determined by changes in aggregate demand.
New Keynesian Economics
- Rejects the simple fixed-price model, favoring a positively sloped aggregate supply curve at low GDP levels.
- Acknowledges wage and price rigidities as reasons for the economy not always being in equilibrium.
- Supports the idea that government intervention is necessary to stabilize the economy.
- Describes that the aggregate supply curve becomes horizontal as industries reach full capacity.
Monetarist Economics
- Led by Milton Friedman; emphasizes the role of money supply in determining real GDP and price levels.
- Argues that deliberate government intervention destabilizes the economy and can create its own business cycles.
- Claims there’s a tradeoff between inflation and unemployment.
- Believes that changes in monetary policy only have short-term effects on real GDP.
- Rejects discretionary monetary policy, advocating for a steady increase in money supply.
Classical Economics
- Assumes real GDP is determined by aggregate supply, while the equilibrium price level is determined by aggregate demand.
- Believes in perfectly flexible wage rates and argues an increase in aggregate demand only raises prices, not output.
- Fails to explain prolonged unemployment during the Great Depression, reducing its acceptance.
New Classical Economics
- Incorporates rational expectations, suggesting unemployment is temporary as the economy seeks equilibrium.
- Asserts that unexpected changes in monetary policy can affect real GDP.
- States that both short-run and long-run aggregate supply curves can be vertical, indicating no trade-off between inflation and unemployment in the long run.
Key Differences Between Schools of Thought
- New Keynesians and Keynesians believe in wage and price rigidity, unlike classical and new classical economists.
- Monetarists and new classical economists advocate less government intervention compared to new Keynesians.
- Both new classical and monetarist schools challenge the effectiveness of government policies in correcting economic disequilibrium.
Additional Concepts
- Recognition lag is the time taken for policymakers to identify economic issues.
- Effect lag refers to the time it takes for policy changes to impact real GDP.
- Reaction lag describes the delay between monetary supply changes and real GDP adjustments.
