Analyze the mechanics of the 'Balassa-Samuelson Effect' in international economics. How does differential productivity growth between sectors impact the real exchange rate?
A. Higher productivity in the tradable goods sector drives up domestic wages, leading to higher prices for non-tradable goods and an appreciation of the real exchange rate✓ Correct Answer
B. Rapid growth in the non-tradable sector reduces export competitiveness and causes a depreciation of the nominal exchange rate
C. Equal productivity growth across all sectors neutralizes price differentials and maintains constant purchasing power parity
D. Lower productivity in agricultural sectors forces governments to subsidize imports, stabilizing the domestic price index
💡 Solution & Explanation
The Balassa-Samuelson effect explains why countries with high productivity in tradable goods often exhibit higher price levels and appreciated real exchange rates. Wage equalization across sectors within a country means productivity gains in tradables raise wages economy-wide, which increases the relative price of labor-intensive non-tradables. This structural phenomenon implies that price levels across countries do not fully equalize even when converted at nominal exchange rates. Developing nations typically experience real exchange rate appreciation as their productivity converges with advanced economies.
