In microeconomics, what does an expansion path illustrate?
A. The combination of factor inputs that minimizes costs for every level of output as factor prices remain constant.✓ Correct Answer
B. The shift in consumer demand curves as national income grows over successive fiscal years.
C. The long-run adjustment of market prices due to structural inflation in an open economy.
D. The upward trajectory of corporate profits in response to aggressive monopolistic expansion.
💡 Solution & Explanation
An expansion path connects the points of tangency between isoquants and isocost lines, illustrating how a firm scales its optimal input combination as output increases while relative factor prices remain constant. Other choices incorrectly describe shifts in consumer demand curves or corporate profit trajectories rather than production theory principles.
