Crowding Out: Topic Checklist (Macroeconomics 5.5)

Specific “I can…” statements for crowding out, each linked to the guide section and practice question that shows whether you can really do it.

Work through the list without notes. If you cannot do a statement, follow its link, then come back. Guide = study guide; Practice = practice questions.

Understanding

  • I can define crowding out in one sentence, naming the real interest rate and interest-sensitive private spending. (Guide: “Why a deficit means borrowing”; Practice Q1)
  • I can explain why a government with a budget deficit usually has to borrow. (Guide: “Why a deficit means borrowing”)
  • I can give examples of interest-sensitive spending and say why everyday spending is less affected. (Guide: “How government borrowing crowds out private investment”; Practice Q3)

Skills

  • I can draw a correctly labelled loanable funds graph and show extra government borrowing as a rightward shift of demand, with the real interest rate rising. (Guide: Figure 1; Practice Q6(a))
  • I can show the same change as a leftward shift of supply, and I know never to shift both curves. (Guide: “Another way to draw it”)
  • I can calculate the new equilibrium, the private investment crowded out and the extra saving from simple loanable funds equations. (Guide: Worked example 1; Practice Q2, Q5)
  • I can check that government borrowing equals extra saving plus investment crowded out. (Guide: Worked example 1; Practice Q5(c))

Reasoning

  • I can explain why crowding out makes the AD shift from deficit-financed spending smaller than the multiplier alone predicts. (Guide: Worked example 2(a); Practice Q6(c))
  • I can explain how crowding out can lower capital accumulation and slow long-run growth, using LRAS. (Guide: Worked example 2(b)–(c), Figure 2; Practice Q4, Q6(d))
  • I can explain why crowding out is larger when saving responds less to the real interest rate. (Guide: “What makes crowding out bigger or smaller”; Practice Q7)
