If inflation is expected to grow, all else equal, the demand for cars estate _______ and the interest rate ________.

Question

Expected inflation raises the incentive to buy durable goods now because consumers expect higher future prices, so the demand for cars (estate) increases; at the same time nominal interest rates rise.

1) Relevant concepts:
- Intertemporal substitution for durable goods: if prices are expected to be higher later, buyers prefer to purchase today, raising current demand for durables (cars/estate cars).
- Fisher equation (nominal interest rate decomposition): i = r + π^e, where i is the nominal interest rate, r is the real interest rate, and π^e is expected inflation.
- Monetary policy response: central banks may also raise policy rates when inflation expectations rise to stabilize prices, reinforcing upward pressure on nominal rates.

2) Step-by-step reasoning:
- If expected inflation (π^e) increases, consumers anticipate higher future car prices and therefore accelerate purchases to avoid paying more later. That increases present demand for cars (estate models included).
- Using the Fisher equation, an increase in expected inflation mechanically raises nominal interest rates: Δi = Δπ^e (holding the real rate r constant). Even if the real rate adjusts somewhat, the typical short-run result is a higher nominal rate.
- Additionally, higher demand for loans to finance earlier purchases and central bank tightening push market interest rates up further.

3) Intermediate “calculation” (algebraic demonstration):
- Start: i = r + π^e.
- If π^e increases by x, then i increases by approximately x (Δi = Δπ^e) unless r changes by the same amount; monetary tightening tends to keep r stable or higher, so i rises.

4) Why the correct answer is correct:
- The first blank is “increases” because expected inflation creates an incentive to buy now rather than later.
- The second blank is “rises” because nominal interest rates incorporate expected inflation (Fisher effect) and central banks/lenders react by raising rates.

5) Why the other options are incorrect:
- “Decreases” for demand contradicts the incentive to buy now under expected inflation.
- Any option pairing “increases” with “falls” contradicts the Fisher effect and typical monetary responses.
- “Decreases; rises” gets the demand direction wrong.

Conclusion: Demand for cars (estate) increases and the interest rate rises, matching the provided answer “increases; rises.”
