Inflation Impact on Real Exchange Rate Quiz: Relative Prices

When domestic inflation rises and the nominal exchange rate stays fixed, domestic goods become more expensive relative to foreign goods. This reduces the real exchange rate, meaning the domestic currency depreciates in real terms. The higher domestic price level lowers the real value of the currency even though its nominal exchange rate has not changed.

The answer is False. When a country has higher inflation than its trading partner and the nominal rate is fixed, the domestic price level rises faster than the foreign price level. This makes domestic goods relatively more expensive, which depreciates the real exchange rate. A real appreciation would require domestic prices to fall relative to foreign prices.

With Country X's inflation at 6 percent and Country Y's at only 2 percent, Country X's price level rises faster. Since the nominal rate is fixed, this higher domestic price level increases the denominator in the real exchange rate calculation relative to the foreign price level, causing Country X's real exchange rate to depreciate.

Under a flexible exchange rate system, a country with higher inflation typically sees its nominal exchange rate depreciate. If the nominal depreciation equals the inflation differential, the real exchange rate stays roughly stable. This relationship is consistent with purchasing power parity, where exchange rate movements tend to offset inflation differences over time.

The answer is True. Although short-term nominal depreciations can partially offset the impact of high inflation on the real exchange rate, persistent inflation continuously pushes domestic prices higher. Over time, this erodes real competitiveness because inflation tends to outpace nominal exchange rate adjustments, steadily reducing the purchasing power of the currency in real terms.

Inflation is one of the most powerful drivers of real exchange rate movements. Higher domestic inflation depreciates the real rate, while lower inflation improves real competitiveness. Over time, persistent inflation differentials between countries generate sustained real exchange rate trends, with high-inflation countries experiencing ongoing real depreciation relative to lower-inflation trading partners.

When the nominal exchange rate depreciates by exactly the same percentage as the domestic inflation differential, the two effects cancel each other out. The depreciation lowers the currency's nominal price by the same amount that inflation raised domestic prices, leaving the real exchange rate approximately unchanged. This outcome is consistent with purchasing power parity adjustments.

The answer is False. While purchasing power parity predicts that nominal exchange rates should adjust to offset inflation differences over time, this does not happen automatically or precisely in the short run. Many other factors influence nominal exchange rates, including interest rates, capital flows, and market sentiment, meaning the nominal rate rarely adjusts by exactly the amount of the inflation differential.

Purchasing power parity is the theory that exchange rates between countries should adjust over time to reflect differences in their price levels or inflation rates. According to this theory, if one country has persistently higher inflation, its currency should depreciate in the nominal exchange rate to restore the real exchange rate toward its equilibrium value.

When domestic inflation rises by 4 percent but the nominal rate falls by only 2 percent, the real exchange rate depreciates because the inflation increase is not fully offset by the nominal depreciation. Domestic goods become more expensive in real terms relative to foreign goods, reducing the manufacturer's competitiveness in international markets.

Persistent high inflation relative to trading partners steadily depreciates the real exchange rate. This makes exports less competitive and imports cheaper in real terms, shifting purchasing toward foreign goods. Over time, the country faces pressure to depreciate its nominal rate to restore balance, while exporters may lose market share as their goods become relatively expensive abroad.

The answer is True. Deflation means the domestic price level falls, making domestic goods cheaper relative to foreign goods. With the nominal exchange rate unchanged, a lower domestic price level raises the real exchange rate, meaning the domestic currency appreciates in real terms. This improves the country's trade competitiveness by making its exports less expensive to foreign buyers.

Economists track inflation differentials because they are the primary driver of real exchange rate movements when the nominal rate is stable. The greater the difference in inflation between two countries, the larger and faster the real exchange rate will diverge from its previous level, affecting trade competitiveness, import prices, and the balance of payments.

To keep the real exchange rate stable when domestic inflation exceeds foreign inflation by 3 percentage points, the nominal exchange rate must depreciate by the same 3 percent. This depreciation offsets the loss of price competitiveness caused by the higher domestic inflation, consistent with the purchasing power parity theory of exchange rate adjustment.

Inflation, nominal exchange rates, and the real exchange rate are tightly connected. Inflation directly raises the domestic price level and depresses the real rate. Nominal exchange rate movements can offset or compound this effect. Purchasing power parity describes the long-run tendency for nominal rates to adjust, and countries with lower inflation generally maintain more competitive real exchange rates over time.
