Question

Quizplus · Accepted Answer

Ridge lines separate the economically relevant portion of an isoquant map from the irrelevant portion. These lines represent the points at which the isoquants are tangent to one another and indicate the least-cost combination of inputs for producing a given level of output. Isocost lines represent different levels of spending on inputs, while opportunity lines and relevance lines are not commonly used terms in this context. Budget lines are used in consumer theory, not in production theory.
