A
Key idea:
An external balance refers to a sustained situation where imports of goods and services are roughly equal to exports of goods and services.
Explanation:
Choice A is correct as contractionary monetary policy in the form of higher interest rates has the following effects:
- disincentivises borrowing by households and firms, lowering consumption spending and domestic investment
- lowering aggregate demand and real GDP
- decreasing imports as AD falls, improving the trade balance
- lowers the average price level, lowers the relative price of exports, increases the relative price of imports, improving the trade balance
- as the trade balance improves, the current account improves and moves toward an external balance
Choices B and D are incorrect because contractionary monetary policy shifts the aggregate demand curve to the left, lowering real GDP in equilibrium.
Choice C is incorrect because although both aggregate demand and real GDP will indeed decrease, it is inaccurate that net exports will also fall, leading to a deterioration of the external balance.
