Study Notes
Economic Theories and Concepts
- Keynes' Law: States that "demand creates its own supply," highlighting the role of demand in driving economic activity.
- Say's Law: Contrasts Keynes' view by asserting that "supply creates its own demand," emphasizing the importance of production in generating demand.
- Neoclassical Economics: Focuses on long-term economic growth, believing that flexible prices and supply primarily determine output.
- Keynesian Economics: Centers on short-term effects, advocating for demand-driven policies to manage economic fluctuations.
Expectations in Economics
- Adaptive Expectations: Suggests that individuals adjust their expectations based on past experiences and gradually modify their behavior in response to changes.
- Rational Expectations: Proposes that people use all available information to form the most accurate expectations about future economic conditions.
Economic Output and Unemployment
- Neoclassical Perspective on Business Cycles: Argues that the economy will revert to its potential GDP over time due to flexible pricing; considers the long-run aggregate supply (AS) curve vertical.
- Keynesian Approach to Unemployment: Emphasizes the need to increase aggregate demand to reduce cyclical unemployment and maintain employment levels during economic downturns.
Aggregate Supply and Demand
- Short-Term vs. Long-Term: Neoclassical economists emphasize long-term growth and view recessions as transient; Keynesians focus on short-term demand management.
- Inflation and Output Relationship: For Neoclassical economists, a vertical long-run AS curve suggests that demand variations do not influence output but only price levels, while Keynesian theory acknowledges an upward-sloping AS curve that permits inflation during growth periods.
Phillips Curve
- Vertical vs. Downward-Sloping: Neoclassical economists see the Phillips curve as vertical, indicating no trade-off between inflation and unemployment in the long run; Keynesians view it as downward-sloping, allowing for short-term trade-offs.
Policy Emphasis and Economic Stabilization
- Neoclassical Policy Recommendations: Focus on reforming labor market institutions to lower the natural unemployment rate, with skepticism towards interventionist policies for cyclical unemployment.
- Keynesian Policy Recommendations: Encourage active measures to counteract economic downturns, asserting that self-correction may not effectively return the economy to full employment quickly.
Summary of Economic Perspectives
- Many mainstream economists adopt a dual perspective, combining Keynesian emphasis on aggregate demand short-term and neoclassical focus on aggregate supply long-term, showcasing the complexity of economic behavior and policy formulation.
