14.1 Competitive Factor Markets Derived demand-Demand for an input that depends on, and is derived from,both the firm's level of output and the cost of inputs. ▣Marginal revenue product(边际收益产出)-Additional revenue resulting from the sale of output created by the use of one additional unit of an input
14.1 Competitive Factor Markets Derived demand - Demand for an input that depends on, and is derived from, both the firm’s level of output and the cost of inputs. Marginal revenue product(边际收益产出)-Additional revenue resulting from the sale of output created by the use of one additional unit of an input
MRPL is measured by the additional output obtained from the additional unit of this labor,multiplied by the additional revenue from an extra unit of output. Because△R/△L=(△R/△Q)(△Q/△L),it follows that MRPL=(MPL)(MR) In a competitive output market,the marginal revenue from the sale of an additional unit of output is then equal to P. MRPL=P(MPL)
MRPL is measured by the additional output obtained from the additional unit of this labor, multiplied by the additional revenue from an extra unit of output. Because R/L= (R/Q) (Q/L), it follows that MRPL = (MPL) (MR) In a competitive output market, the marginal revenue from the sale of an additional unit of output is then equal to P. MRPL = P (MPL)
Wage (dollars per hour) Competitive Output Market MRPL=MPL·P Monopolistic Output Market MRPL=MPL·MR Hours of Work Marginal Revenue Product
Marginal Revenue Product
In a competitive factor market in which the producer is a price taker,the buyer's demand for an input is given by the marginal revenue product curve. The MRP curve falls because the marginal product of labor falls as hours of work increase.When the producer of the product has monopoly power,the demand for the input is also given by the MRP curve.In this case,however,the MRP curve falls because both the marginal product of labor and marginal revenue fall
