Unit 3: AD/AS Model

The equilibrium of AS and AD determines current output (GDPR) and the price level (PL)
Full Employment: occurs where AD intersects SRAS and LRAS at the same time.
Recessionary Gap: exists when equilibrium is below full employment output
Inflationary Gap: exists when equilibrium is beyond full employment output
Changes in AD (u = employment, 𝛑 = inflation)
- Consumption
- Gross Private Investment
- Government Spending
- Net Exports
Changes in SRAS:
- Input prices
- Productivity
- Legal Institutional Environment
GDP and Price Level have an inverse relationship, while Unemployment and Inflation have a direct relationship.
