- Basic Economic Concepts

- AD-AS Model
- Monetary Policy
- Phillips Curve
- Open Economy
You have three days until the AP Macroeconomics exam. This is not the time to learn Unit 1 from scratch — it's time to drill the highest-frequency graph types and lock in the chain-reaction reasoning the College Board reuses every single year.
This plan assumes ~4 focused hours per day. You must know six graphs cold: PPC, S&D, AD-AS, money market, loanable funds, Phillips curve (short + long run), and FOREX. Skip nothing on the checklist.
Day 1: Foundations + Economic Indicators (4 hrs)
The first 20+ multiple-choice questions lean on these. Get them automatic.
What to review (90 min)
- PPC/PPF: production possibilities. Know the axes (two goods or capital vs consumption), efficiency curve, opportunity cost (the slope), comparative advantage (different PPCs between nations), and resource exhaustion (inward shift).
- Supply & Demand: equilibrium mechanics, law of demand (downward slope), law of supply (upward slope), determinants of shifts (income, preferences, input prices, expectations). Labeling: price on Y-axis, quantity on X-axis, intersect = equilibrium.
- Comparative Advantage: one nation has lower opportunity cost. Recompute from production numbers; don't confuse with absolute advantage.
- GDP and Real GDP: nominal GDP = current prices; real GDP = GDP adjusted to base-year prices. Formula: . GDP is flow, not stock.
- Inflation (CPI): Consumer Price Index measures price level. CPI↑ means inflation. Compute the inflation rate: .
- Unemployment rate: . Remember: discouraged workers are not in the labor force.
What to practice (2.5 hrs)
- 15 mixed multiple-choice on S&D and PPC (shift directions, new equilibrium).
- Draw one S&D graph from scratch: label axes, label curves, mark original equilibrium (E), apply a shift (e.g., "income increases for normal goods"), draw new curve, mark new equilibrium (E₂), show direction of price and quantity change.
- Calculate one real GDP and one inflation rate from a data table.
💡 Highest leverage: Every FRQ starts with a scenario that triggers S&D or PPC thinking. If you can't draw these fast, you'll waste time under pressure. Drill the labeling tonight.
Day 2: AD-AS + Monetary Policy (4 hrs)
These two topics account for nearly 40% of all FRQ points.
What to review (90 min)
- AD-AS model: aggregate demand (downward slope — wealth effect, interest-rate effect, exchange-rate effect), aggregate supply (short-run upward slope, long-run vertical at potential GDP). Axes: price level (Y), real GDP (X).
- Equilibrium shifts: demand-side shocks (fiscal policy, Fed actions) shift AD left/right. Supply shocks (oil prices, technology) shift SRAS left/right. Show shifts with arrows and relabel curves (AD₁, AD₂, etc.).
- Fiscal policy: government spending ↑ or tax ↓ → AD shifts right (expansionary). Multiplier effect: (marginal propensity to save). If MPS = 0.25, multiplier = 4.
- Recessionary gap: real GDP < potential GDP. Policy response: expansionary fiscal (↑G, ↓T) or expansionary monetary (↑MS, ↓interest rate). Inflationary gap: real GDP > potential. Policy response: contractionary.
- Money creation & banking: banks lend out reserves (required reserve = RR × deposits). Money multiplier = . If RR = 10%, money multiplier = 10.
- Fed monetary policy: ↑ interest rate (contractionary): Fed sells securities or ↑ discount rate. ↓ interest rate (expansionary): Fed buys securities or ↓ discount rate. Also: open market operations (OMO).
- Money market graph: vertical MS (money supply set by Fed), downward-sloping MD (money demand). Equilibrium at intersection = market interest rate. If MS ↑, curve shifts right, interest rate ↓.
What to practice (2.5 hrs)
- 1 full FRQ scenario: recession → draw AD-AS shift left → identify gap → explain fiscal policy → draw money market showing decreased demand for money or Fed's action → calculate multiplier effect. Must draw each graph with labels.
- 20 mixed multiple-choice on policy mechanisms and graphs.
- Calculate one money multiplier; identify one OMO effect.
⚠️ FRQ trap: If the question says "The Fed increases the money supply," students often draw money market without shifting MS. MS always shifts when Fed acts. The entire graph should update. Label the new equilibrium point.
Day 3: Long-Run Effects + Open Economy + FRQ Mastery (4 hrs)
What to review (90 min)
- Phillips Curve (short-run): inverse relationship between inflation and unemployment. . Downward slope. Shifts based on expected inflation or supply shocks.
- Phillips Curve (long-run): vertical at natural unemployment rate. No permanent tradeoff. All expansionary policy → long-run: higher inflation, same unemployment.
- Crowding out: when government borrows to finance spending, interest rates ↑, private investment ↓. Draw in loanable funds market: ↑ demand for loanable funds (government borrowing) → interest rate ↑ → investment demand slides down (less private investment).
- Long-run growth: driven by productivity, capital accumulation, technological progress. Monetary policy does not affect long-run real GDP.
- Foreign Exchange (FOREX) market: supply of currency (upward slope — exporters supply dollars) vs. demand (downward slope — foreign buyers demand dollars). Equilibrium = exchange rate (units of foreign currency per dollar).
- Capital inflows: if US assets become attractive, foreign buyers demand more dollars → supply of dollar increases → dollar appreciates (stronger).
- Trade deficit: imports > exports. If US has capital inflow, US dollar appreciates, US goods become expensive abroad, imports ↑, exports ↓ → trade deficit widens.
What to practice (2 hrs)
- 1 timed, full FRQ on expansionary policy chain reaction: economy in recession → Congress passes stimulus → AD-AS shift (gap closes) → interest rates rise (crowding out) → investment falls → long-run growth slows. Draw all graphs: AD-AS (2 versions), loanable funds (2 versions), Phillips (short vs. long run). Label every shift, every new equilibrium.
- 25 mixed multiple-choice (highest-frequency topics).
🎯 Chain-reaction reasoning wins points: FRQs reward explicit language. Do not just draw graphs — write one sentence per shift explaining why each curve moves. Example: "Expansionary fiscal policy increases aggregate demand. Higher income → increased demand for money in money market → interest rate rises. Higher interest rate → investment demand decreases (crowding out)." Rubrics check for this reasoning step-by-step.
The night before
Skim our last-minute review checklist. Get 8 hours of sleep. Short-term memory consolidation is real. A tired brain confuses nominal vs. real GDP.
Common point-leaks
- Forgetting to label axes and equilibrium points on graphs.
- Confusing "increase in demand" with "quantity demanded increases" (one shifts the curve, one moves along it).
- Drawing curves but not showing shifts with arrows and new labels.
- Writing "prices go up" instead of explaining the mechanism (wealth effect, interest-rate effect, etc.).
- Forgetting MPS + MPC = 1, so multiplier = 1/(1 − MPC) or 1/MPS.
- Misidentifying which policy is expansionary vs. contractionary.
- Missing the step: "This policy closes the recessionary gap in the short run but leads to higher inflation long-run" (Phillips curve implication).
What this 3-day plan skips
You will not fully master comparative advantage calculations or detailed trade policy (quotas, tariffs) in 3 days. If you're weak there: memorize the definitions, do 2 example problems on price effects, and accept you may lose 3-5 points. Spend the saved time mastering the six core graphs instead.
