A country, 'Alpha,' has historically maintained a fixed exchange rate regime pegged to the US dollar. Due to persistent balance of payments deficits and declining foreign exchange reserves, the monetary authorities are considering a policy adjustment. An economic advisor suggests that a devaluation of Alpha's currency would address these issues. Which of the following is the most likely short-term consequence of this devaluation, assuming the Marshall-Lerner condition holds?
- AIncreased foreign direct investment (FDI) into Alpha, leading to currency appreciation.
- BA deterioration in the trade balance in the short term, followed by an improvement in the long term (J-curve effect).
- CA decrease in domestic inflation as imported goods become cheaper.
- DAn immediate improvement in the trade balance as exports become cheaper and imports more expensive.
Show answer & explanationAnswer & explanation
Correct answer: B. A deterioration in the trade balance in the short term, followed by an improvement in the long term (J-curve effect).
The J-curve effect describes the typical pattern of a country's trade balance following a currency devaluation. Initially, the trade balance worsens (deteriorates) because import prices rise immediately, while the volume of exports and imports adjusts more slowly due to contractual obligations and time lags in consumer/producer responses. Over time, as volumes adjust, the trade balance improves. This effect holds if the Marshall-Lerner condition is met.
Why the other options are wrong
- A. Incorrect. While devaluation can make assets cheaper for foreigners, immediate FDI might not lead to currency appreciation, and the direct effect is on trade balance.
- C. Incorrect. Devaluation makes imported goods more expensive in local currency terms, leading to higher, not lower, domestic inflation (imported inflation).
- D. Incorrect. This describes the long-term effect, but not the immediate short-term effect due to the J-curve.
J-Curve Effect
The phenomenon where a country's trade balance initially worsens following a currency devaluation or depreciation, before eventually improving.
- Occurs due to time lags in the adjustment of export and import volumes.
- Import prices rise immediately, while demand/supply responses are slower.
- Requires the Marshall-Lerner condition to hold for the eventual improvement.
