What economic phenomenon does the 'Balassa-Samuelson Effect' explain regarding price level differences between countries with varying levels of productivity?
A. Higher labor productivity in the tradable goods sector drives up wages across the entire economy, leading to higher price levels in richer nations.✓ Correct Answer
B. Exchange rates fluctuate purely based on nominal interest rate differentials rather than purchasing power parity.
C. Protectionist tariffs imposed on manufactured goods reduce domestic consumer surplus in developing economies.
D. Capital mobility across international borders equalizes real wage rates across all participating developing nations.
💡 Solution & Explanation
The Balassa-Samuelson effect demonstrates that countries with high labor productivity in the tradable goods sector experience higher economy-wide wage levels, which subsequently translates into higher overall price levels and services costs in richer nations. This explains why purchasing power parity frequently fails to hold internationally even when tradable goods prices equalize. Non-tradable services are inherently more expensive in high-productivity economies due to wage spillovers.
