Automatic Stabilizers: Topic Checklist (Macroeconomics 3.9)

Specific “I can…” statements for automatic stabilizers, 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 an automatic stabilizer in one sentence, using the idea that no new government decision is needed. (Guide: “The idea: a fiscal policy that runs itself”; Practice Q1)
  • I can tell an automatic stabilizer from discretionary fiscal policy in a given example. (Guide: Worked example 3; Practice Q1)
  • I can explain why tax revenue changes with real GDP even when tax rates stay the same. (Guide: “Taxes as automatic stabilizers”; Practice Q2)
  • I can name transfer payments that act as automatic stabilizers and say which way they move in a recession and in an expansion. (Guide: “Transfer payments as automatic stabilizers”)

Calculation

  • I can calculate the automatic change in tax revenue and in transfer payments from data. (Guide: Worked examples 1 and 2; Practice Q5(a), Q6(c)–(d))
  • I can calculate the change in disposable income and the first-round change in consumption, and compare it with an economy without stabilizers. (Guide: Worked example 1; Practice Q3, Q5(c), Q6(d))
  • I can compare the revenue from a proportional tax and a fixed tax when income changes. (Practice Q7(a)–(c))

Reasoning

  • I can explain how falling tax revenue and rising transfers support consumption and moderate a recession. (Guide: Worked example 1; Practice Q6(e))
  • I can explain how rising tax revenue and falling transfers slow consumption and help prevent overheating in an expansion. (Guide: Worked example 2; Practice Q5(c), Q7(d))
  • I can draw an AD–AS graph showing that AD shifts by less with stabilizers, so real GDP and the price level change by less. (Guide: Figure 1; Practice Q6(a)–(b), (e))
  • I can explain why stabilizers avoid the lags of discretionary policy but do not, on their own, close an output gap. (Guide: “Strengths and limits”; Practice Q4)
