A decision you can investigate
- A public purchase directly adds demand for production. A tax cut first changes disposable income, of which households may save part.
- Equal budget costs need not give equal initial demand changes.
Build the explanation
- Fiscal policy 财政政策 changes public spending and taxation; monetary policy changes monetary and financial conditions through the central bank and related institutions. Reflationary demand policy seeks to increase spending, often when there is a negative output gap; deflationary demand policy seeks to restrain spending and inflation pressure. A tax cut or higher public purchases can be expansionary; tax increases or spending reductions can be contractionary, depending on financing and responses.
- Public purchases enter G directly. Transfers affect recipients’ disposable income and then consumption or saving rather than automatically entering G. Direct taxes affect disposable income and incentives; indirect taxes can also change prices. Fiscal measures may affect both AD and capacity, but the short-run spending mechanism differs from a later supply improvement. Automatic tax/benefit changes during the cycle differ from a new discretionary decision.
Work through the evidence
- In a fictional closed fixed-price model with no imports or proportional taxes, MPC=0.75 and the spending multiplier is 4. An autonomous G purchase increase 20 initially adds 20 demand; total model income rises 80 if the assumptions hold. A separate lump-sum tax cut 20 increases disposable income 20, of which initial consumption is 15 and saving 5. Its total model demand effect is 15×4=60, not 80.
- In a separate balanced-budget change, G rises 20 and lump-sum taxes rise 20 together: initial net spending change=20−15=5, with total model income change 20. The tax and spending changes have equal budget amounts but different first-round expenditure effects. These are fixed-propensity calculations, not universal fiscal forecasts.

Test the limits
- Government borrowing, interest rates, imports, expectations, capacity and implementation timing can change the effects. At capacity, stimulus may raise prices more than real output; debt-service costs and possible displacement of private activity matter. Fiscal contraction can weaken employment and public services even while reducing demand pressure.
- Tax cuts may be saved if confidence is weak; purchases can be delayed or poorly targeted. Progressive taxes and benefits can stabilize disposable income automatically, but a cyclical deficit is not identical to a deliberate stimulus. Compare timing, distribution, fiscal sustainability and the type of shock. Use the withdrawal-based multiplier when taxes/imports change with income; do not reuse this closed lump-sum model unchanged.

Apply and explain your answer
- Why does the equal-size tax cut give a smaller demand increase than the public purchase in this model?
- Only 75% of the additional disposable income is initially consumed. The G purchase directly adds 20, whereas the tax cut initially adds 15 consumption.

Use the terms precisely
- fiscal policy: Policy changes to government spending and taxation.
- reflationary policy 扩张性需求政策: Policy intended to increase aggregate demand under the stated conditions.
