Exam: 2 hours 10 minutes - 60 MCQ (70 min, 66.6%) + 3 FRQ (60 min, 33.3%) Calculator: Not allowed Scope: AP Macroeconomics

| Q2 | Short FRQ (5 points): Concept application | 5 pts |
| Q3 | Short FRQ (5 points): Graph interpretation | 5 pts |
FRQ Tips
- Draw aggregate demand/aggregate supply graphs for every macro FRQ
- Label axes: Real GDP (Y) on x-axis, Price Level (P) on y-axis
- Show multiplier calculations: DeltaGDP = Multiplier × DeltaSpending
- For policy questions: distinguish between short-run and long-run effects
- Always connect monetary policy transmission to the money market graph
Additional Macro FRQ Tips
- AD-AS always first: Start every macro FRQ by drawing the AD-AS graph; label the axes (Real GDP on x, Price Level on y)
- Multiplier calculations: Show the multiplier formula and substitute numbers; state your MPC/MPS
- Phillips Curve questions: Distinguish short-run (downward sloping) vs. long-run (vertical); know when SRPC shifts
- Open economy: For exchange rate questions, use the foreign exchange graph; show supply/demand for dollars
- Loanable funds market: Government deficit -> demand for loanable funds shifts right -> real interest rate rises -> crowding out
- Spending vs. tax multiplier: |Tax Multiplier| < Spending Multiplier (because part of tax cut is saved)
- Partials are real: Write the correct equation even if you can't solve it numerically
Unit 1: Basic Economic Concepts

Unit 2: Economic Indicators and the Business Cycle
Circular Flow Model
- Two-sector model (Households + Firms):
- Product market: Firms sell goods/services to households (clockwise flow)
- Factor market: Households supply labor, land, capital, entrepreneurship (counterclockwise flow)
...

Gross Domestic Product Definition
- Market value of all final goods and services produced within a country's borders in a given period
- Final goods: Avoids double-counting intermediate goods
- Domestic: geographic-based, includes foreign firms producing in the country

Unit 3: National Income and Price Determination
Wealth Effect
- Also called real balance effect
- Lower price level -> households' real wealth increases -> more consumption
- Higher price level -> real wealth decreases -> less consumption
...
Practice
Interest Rate Effect
- Lower price level -> households need less money for transactions -> money demand decreases -> interest rates fall -> investment increases
- Higher price level -> money demand increases -> interest rates rise -> investment decreases
- Strongest of the three effects for downward-sloping AD
Practice
Unit 4: Financial Sector
Liquidity
- Ease with which an asset can be converted into cash without significant loss of value
- Most liquid: Currency, checking deposits
- Less liquid: Savings accounts, money market accounts
...
Practice
Stocks Vs Bonds
- Stocks (equity): Ownership share in a corporation
- Potential for capital gains and dividends
- Higher risk, higher expected return
...
Practice
Unit 5: Long-Run Consequences of Stabilization Policies
Policy Mix
- Combination of fiscal and monetary policies
- Expansionary fiscal + expansionary monetary: Strong stimulus, lower interest rates (if monetary dominates)
- Expansionary fiscal + contractionary monetary: Higher interest rates, crowding out, currency appreciates
...
Practice
Impact On Ad
- Short run: Both fiscal and monetary policy affect AD
- Expansionary policy -> AD shifts right -> P up , Y up
- Contractionary policy -> AD shifts left -> P down , Y down

Unit 6: Open Economy - International Trade and Finance
Current Account
- Trade balance: Exports of goods and services minus imports
- Net income: Investment income (dividends, interest) earned minus paid abroad
- Net transfers: Unilateral transfers (remittances, foreign aid) received minus paid
...
Practice
