# Fiscal Policy

Business I · Introduction to Economics · https://tryals.app/learn/business-i/fiscal-policy

## The Government's Two Levers

**Fiscal policy** is the use of government **spending** and **taxation** to steer aggregate demand directly.

- **Expansionary**: raise spending or cut taxes to fight recessions.
- **Restrictive**: cut spending or raise taxes to cool overheating.

The budget position keeps score:

$$\text{deficit} = \text{spending} - \text{revenue}$$

Deficits accumulate into **public debt**: future taxpayers financing today's demand.

**Automatic stabilizers** work without any vote: tax receipts fall and benefits rise automatically in a downturn, cushioning demand instantly.

## Multipliers and Limits

**The multiplier.** One euro of spending becomes income, spent again. With a marginal propensity to consume ($MPC$), the total demand effect is:

$$\text{multiplier} = \frac{1}{1 - MPC}$$

> **Common pitfall:** Textbook multipliers are unrealistically large. Real-world leakages like imports, taxes, and saving shrink the actual impact.

| | Fiscal policy | Monetary policy |
|---|---|---|
| **Who** | Government | Central bank |
| **Lever** | Spending and taxes | Interest rates |

**Limits**: Slow decision **lags** and **crowding out**, where public borrowing pushes up interest rates and displaces private investment.

## Practice questions

7 of this lesson's 14 practice questions, with answers. The full set is in the app.

### 1. Why might a large debt-financed stimulus partially _undermine itself_?

A. Deficits automatically cause equal trade surpluses
B. Heavy public borrowing can crowd out private investment
C. The multiplier only works for tax cuts
D. Government spending never reaches the real economy

**Answer:** B. Heavy public borrowing can crowd out private investment

**Why:** The state and firms fish in the same pool of savings. Massive public borrowing bids up interest rates, and marginal private projects die, crowding out clawing back part of the stimulus.

### 2. The same stimulus produces a much larger effect in a deep recession than in a boom. What accounts for the difference?

A. Governments spend the money more efficiently during recessions
B. The multiplier is a fixed number, so the difference must be measurement error
C. Idle resources, which a slump has and a boom does not
D. Interest rates are always lower in recessions, which amplifies the effect

**Answer:** C. Idle resources, which a slump has and a boom does not

**Why:** Spending only creates output if there is slack to activate; at full employment it moves resources rather than adding them, and the effect shows up in prices. The multiplier is therefore state-dependent, which is why 'does stimulus work?' has no answer without asking *when*.

### 3. Which are genuine limitations of discretionary fiscal policy?

A. Budgets take months to approve and deploy
B. Politically, stimulus is easier to start than to withdraw
C. It cannot affect aggregate demand at all
D. Accumulated deficits raise debt-sustainability concerns

**Answer:** A. Budgets take months to approve and deploy; B. Politically, stimulus is easier to start than to withdraw; D. Accumulated deficits raise debt-sustainability concerns

**Why:** Fiscal policy moves demand powerfully, that’s not the problem. Lags, debt, and the ratchet of popular spending are.

### 4. The spending multiplier is larger when the marginal propensity to consume is higher. Why does that make the multiplier weaker in an open economy?

A. Because the multiplier applies only to closed economies by definition
B. Because open economies have lower marginal propensities to consume
C. Because exchange rates always offset fiscal policy exactly
D. Because income spent on imports leaves the domestic circuit

**Answer:** D. Because income spent on imports leaves the domestic circuit

**Why:** Every leak shrinks the geometric series. Saving, tax and imports all divert income from the next round, which is why small open economies get less domestic traction from the same package.

### 5. A country running a budget deficit must see its public debt rise as a share of GDP.

**Answer:** False

**Why:** False. The ratio falls whenever nominal GDP grows faster than debt, so a country can run a deficit and still deleverage, which is how much of the post-1945 debt burden was reduced. The condition is that growth plus inflation exceed the effective interest rate, not that the deficit be zero.

### 6. Sort each stabilizing force: automatic stabilizer or discretionary measure?

**Answer:**

- Automatic stabilizer: Unemployment benefits rising as layoffs spread, Income tax receipts falling in a recession, Progressive taxation braking booms by itself
- Discretionary measure: Parliament votes a new stimulus package, A temporary VAT cut announced for six months

**Why:** Stabilizers are built into the rules and respond instantly; discretionary policy needs a decision, a vote, and time.

### 7. Match each fiscal concept to its definition.

**Answer:**

- Budget deficit → Spending exceeding revenue in a year
- Public debt → Accumulated deficits over time
- Crowding out → Public borrowing displacing private investment
- Automatic stabilizer → Built-in cushioning that needs no vote

**Why:** Flow (deficit) versus stock (debt), plus the two forces — one hostile, one helpful — that ride along with fiscal action.
