Question

marginal product measures the change in:
a. the firms output brought about by employing one additional unit of input.
b. a firms revenue brought about by changing production by one unit.
c. total cost brought about by changing production by one unit.
d. product price brought about by changing production by one unit.

Explanation:

Marginal product is a core concept focused on the relationship between input and output in production. It specifically quantifies how much total output changes when one more unit of a production input (like labor or capital) is added, holding other inputs constant. Option b refers to marginal revenue, option c refers to marginal cost, and option d describes a change related to price and output, which is not marginal product.

Answer:

a. the firm's output brought about by employing one additional unit of input.
