Study Notes
Macroeconomic Models
- Classical Model emphasizes markets always clear and self-adjusting economies.
- Fixed-Price Keynesian Model complements classical perspectives by focusing on short-term price rigidity.
Classical Model Overview
- Markets clear at equilibrium: supply equals demand.
- Limited government intervention is a key principle.
- Relies on rational choice theory among consumers and firms.
Key Characteristics of the Classical Model
- Involuntary unemployment does not occur at equilibrium.
- Wages are flexible, allowing the economy to adjust to changes.
- Higher unemployment due to labor demand decreases can lead to a surplus.
Assumptions of the Classical Model
- Rational self-interest drives decision-making; firms aim to maximize profits while households maximize utility.
- Flexibility of wages, prices, rents, and interest rates ensures market equilibrium.
- Economic choices are based on real variables, avoiding money illusion.
Variables in Economics
- Nominal Variables: expressed in monetary terms.
- Real Variables: measured in physical quantities, reflecting actual economic activity.
Labor Market Dynamics
- Law of diminishing returns indicates that increasing labor quantity will lower the marginal returns of labor.
- Classical model considers labor markets self-clearing.
Policy Implications
- Fiscal policy is largely ineffective in the Classical Model due to self-adjusting nature.
- Monetary policy can be more effective in influencing economic conditions.
Labor Market Equations
- Real wage rate (W) determined by nominal wage rate divided by price level.
- Quantity of labor (L) influences overall output (Y).
Production Function
- Simple function: y = F(K, L) representing output as a function of capital (K) and labor (L).
- The production curve showcases an upward arching supply-side relationship.
Labor Demand and Supply
- Labor demand maximized where wage equals marginal product of labor (MPL).
- Households decide on labor supply based on the trade-off between income and leisure.
Aggregate Market Dynamics
- Aggregate demand (AD) represents total desired spending, while aggregate supply (AS) reflects total output.
- Changes in price influence both the real wages received and the quantity of labor supplied.
Equation of Exchange
- Fundamental equation: M x V = P x Y relates money supply with velocity and nominal GDP.
- Indicates that real GDP remains constant regardless of price level fluctuations in the Classical Model.
