✨ Macroeconomic Indicators

Code
GDP = C + I + G + (X – M)


●​ C: consumer spending
●​ I: investment
●​ G: government spending
●​ X–M: net exports

Real GDP = adjusted for inflation

Nominal GDP = current prices


✨ Unemployment Types
●​ Frictional — between jobs
●​ Structural — skills mismatch
●​ Cyclical — recession‑based
●​ Seasonal — predictable patterns


✨ Inflation
CPI Formula:

Code
(CPI₂ – CPI₁) / CPI₁

Demand‑pull inflation: too much spending

Cost‑push inflation: rising production costs


✨ Business Cycle

, Code
Expansion → Peak → Contraction → Trough



✨ Aggregate Demand (AD)
Downward sloping because of:

●​ wealth effect
●​ interest rate effect
●​ exchange rate effect


✨ Aggregate Supply (AS)
●​ SRAS: upward sloping
●​ LRAS: vertical at full employment

Stagflation = SRAS shifts left

Multiplier:

Code
1 / (1 – MPC)

Buy bonds → MS ↑ → interest rates ↓
