A decision you can investigate
- A government can commission a bridge or pay a household benefit. Both use public funds, but only the first directly purchases current output.
- A budget label does not replace national-accounting classification.
Build the explanation
- Government purchases 政府购买 G contribute directly to AD. A transfer payment 转移支付 provides funds without buying current output. Spending decisions can reflect fiscal stabilization, the level of economic activity, attempts to correct market failure and policy priorities. In a downturn, discretionary purchases may rise to support demand; automatic benefit payments may also rise as unemployment increases, affecting household income rather than entering G directly.
- A public-good service or education infrastructure can be justified by a different objective from immediate stabilization. Spending composition, financing and implementation determine the effect. Public purchases can support capacity over time, while current services may chiefly meet present needs. The government faces opportunity costs even if unused resources make a short-run expansion easier.
Work through the evidence
- A fictional programme raises domestic government purchases by 40 and pays additional household transfers 20. The direct G increase is 40. If recipients spend 15 of the transfers on domestic output and save 5, the immediate C contribution is 15 under the stated assumptions. Direct planned domestic demand therefore increases 40+15=55 before further feedback, not 60 automatically and not 75 by counting transfers twice.
- If the purchases include imported equipment worth 10 already inside the 40, subtract that import increase in X−M: immediate domestic contribution becomes 30+15=45, assuming the household purchases contain no imports. This separates spending labels from domestic-production content.
What is the direct G increase before import adjustment?
The 20 household transfer is not a direct purchase.
Test the limits
- Government expenditure responds to priorities and constraints, not only recession. Correcting an externality may call for regulation or incentives rather than simply more purchases. Financing through taxes or borrowing can affect private spending, interest, confidence and future fiscal room; those effects require assumptions, not automatic crowding-out claims.
- Procurement delays, skills, imported inputs and delivery quality matter. A bridge project may add demand before opening but only improve supply after completion and effective use. Judge timing, additionality, domestic content, opportunity cost and who benefits rather than assuming every pound or yuan of public outlay raises GDP by one.
What immediate domestic-demand increase follows the stated spending and import assumptions?
Domestic G 30 plus C 15 equals 45.
Every government cash payment enters the G component of AD directly.
Transfers influence recipient choices; direct purchases have a different accounting role.
Apply and explain your answer
- Why does the imported equipment reduce the direct domestic-demand contribution?
- It is already inside G but is produced abroad, so the corresponding rise in M removes it from domestic-output demand.
Which can influence public purchases apart from stabilization?
Public-good, capacity and service choices have distinct purposes.
Use the terms precisely
- government purchases: Public expenditure directly buying goods or services within the stated accounting period and scope.
- transfer payment: A payment without a corresponding purchase of current goods or services.
Match the terms to their meanings.
Use each term for its stated economic relationship.
