Full lesson, practice questions & flashcards →What to master for the exam
- Know what counts in GDP (final goods, produced this year, inside the country) and what does not (transfers, used goods, intermediate goods).
- Classify unemployment as frictional, structural, or cyclical, the natural rate includes only the first two.
- Calculate inflation with CPI and convert nominal to real using the deflator or real = nominal ÷ price index × 100.
- Label the business cycle phases (expansion, peak, contraction/recession, trough) and tie them to output gaps.
AP Macro Unit 2: common questions
What is on AP Macro Unit 2?
GDP measurement and the circular flow, GDP's limitations, the three types of unemployment and the unemployment rate, CPI and inflation, real vs nominal GDP, and the phases of the business cycle. It is worth 12–17% of the AP Macro exam.
What are the four phases of the business cycle?
Expansion (rising real GDP), peak (the top, where an inflationary gap is most likely), contraction or recession (falling real GDP with rising cyclical unemployment), and trough (the bottom, where recovery begins). Actual output fluctuates around the long-run growth trend of potential output.
