A firm in Hong Kong faces a kinked isoquant due to a production process with fixed proportions (Leontief technology). The firm's expansion path is:
A. A straight line from the origin
B. A vertical line
C. A horizontal line
D. A ray from the origin with slope determined by the fixed ratio✓ 答案
解說
With fixed-proportions technology, cost-minimising input combinations must maintain the fixed ratio. The expansion path is a ray from the origin with slope equal to the required capital-labour ratio.
