An individual firm's demand for a factor of production ?

Correct answer: B. Slopes downward due to the factor's diminishing marginal product

  • A. Slopes downward because an increase in the production of output reduces the price at which the output can be sold in a competitive market, thereby reducing the value of the marginal producing the value of the marginal product as more of the factor is use
  • B. Slopes downward due to the factor's diminishing marginal product
  • C. slopes upward due to the factor's increasing marginal product
  • D. is perfectly elastic (horizontal) if the factor market is perfectly competitive

Explanation

A firm's factor demand slopes downward because the factor's marginal product normally diminishes as more of it is employed, reducing its value at the margin. Perfect competition in the factor market makes the firm's factor supply, not its demand, horizontal.
