Solution
a
Marginal Revenue Product (MRP) Definition: The marginal revenue product of labor (MRP_L) is the additional revenue generated from employing one more unit of labor
b
MRP Calculation: Given that the firm can sell as many pillows as it wants for $10, the MRP for each worker is calculated as the marginal product (MP) of labor multiplied by the price of the product
c
MRP of Fourth Worker: From the table, the MRP of the fourth worker is $150
d
Marginal Product Calculation: To find the marginal product (MP) of the fourth worker, we use the formula MRP=MP×PMRP = MP \times P. Given MRP=150MRP = 150 and P=10P = 10, we solve for MPMP: 150=MP×10 150 = MP \times 10 MP=15010=15 pillows MP = \frac{150}{10} = 15 \text{ pillows}
Answer
(D) 15 pillows
Key Concept
Marginal Revenue Product (MRP)
Explanation
The marginal revenue product of labor is the additional revenue generated from employing one more unit of labor. Given the MRP and the price of the product, we can calculate the marginal product of labor. For the fourth worker, the MRP is 150,andthepriceperpillowis150, and the price per pillow is 10, leading to a marginal product of 15 pillows.
