conditional factor demand造句

When relative input usages are optimal, the marginal rate of technical substitution is equal to the relative unit costs of the inputs, and the slope of the isoquant at the chosen point equals the slope of the isocost curve ( see Conditional factor demands ).
Likewise, in the theory of the firm, the lemma gives a similar formulation for the conditional factor demand for each input factor : the derivative of the cost function " c ( "'w "', y ) " with respect to the factor price:
Economists Alfred Stonier and Douglas Hague defined " expansion path " as " that line which reflects the least cost method of producing different levels of output, when factor prices remain constant . " The points on an expansion path occur where the firm's isocost curves, each showing fixed total input cost, and its isoquants, each showing a particular level of output, are tangent; each tangency point determines the firm's conditional factor demands.
