Which option correctly describes import penetration versus export performance?

Which option correctly describes import penetration versus export performance?

• A. Import penetration measures the level of tariffs on imports; export performance measures the level of tariffs on exports
• B. Import penetration measures the ratio of imports to GDP; export performance measures the ratio of exports to GDP
• C. Import penetration measures the elasticity of demand for imports; export performance measures the elasticity of demand for exports
• D. Import penetration measures the extent to which imports are increasing; export performance measures the extent to which exports are increasing

Answer: (D)

The idea being tested is how we describe trade performance in terms of growth. Import penetration and export performance are about how fast imports and exports are changing over time, rather than the level of tariffs, or their shares of GDP, or how responsive demand is to price. So the best description is that each measure reflects the extent to which imports and exports are increasing. Why this fits: Import penetration here is about how much imports are rising relative to domestic demand, and export performance is about how fast exports are rising. This focuses on growth in trade flows, which is what these terms are intended to capture. Why the other descriptions don’t fit: measuring tariffs would be about policy levels, not penetration or performance; using imports-to-GDP or exports-to-GDP describes a stock or share in the economy, not the rate of growth; elasticity concerns how demand responds to price changes, not the growth rate of trade flows.
