Absolute Advantage Explains Higher Productivity

Steps:

• Identify the scenario: Germany produces more pharmaceuticals per resource unit than Pakistan, indicating superior efficiency.
• Recall absolute advantage: A country has it if it produces more output with the same resources compared to another.
• Apply to question: Germany's higher output per resources fits absolute advantage in pharmaceuticals.
• Rule out unrelated concepts: Exchange rates, trade conditions, and terms don't directly explain production efficiency.

Why B is correct:

• The law of absolute advantage states a country benefits from specializing in goods it produces more efficiently (higher output per input) than others, directly explaining Germany's edge.

Why the others are wrong:

• A: Floating exchange rates affect currency values and trade flows, not production efficiency.
• C: The Marshall-Lerner condition determines if devaluation improves trade balance, unrelated to output per resources.
• D: Terms of trade involve export/import price ratios, not domestic production productivity.

Final answer: B
