Definition§
Marginal Product (MP) is the change in total output (quantity produced) that results from using one additional unit of a given input, while holding all other inputs constant. This concept is used to analyze the efficiency and productivity of different factors of production, such as labor, capital, and land.
Examples§
- Labor: If a factory produces 100 widgets with 10 employees and increases production to 110 widgets with 11 employees, the marginal product of labor for the 11th employee is 10 widgets.
- Capital: If a farm produces 500 bushels of wheat with 1 tractor and increases production to 550 bushels with 2 tractors, the marginal product of the second tractor is 50 bushels.
- Raw Materials: If a bakery produces 200 loaves of bread with 50 kg of flour and increases production to 220 loaves with 60 kg of flour, the marginal product of the additional 10 kg of flour is 20 loaves.
Frequently Asked Questions (FAQs)§
Q: What is the relationship between Marginal Product and Marginal Cost? A: Marginal Product and Marginal Cost are inversely related. As the Marginal Product of an input increases, the Marginal Cost of producing an additional unit of output decreases.
Q: What does the Law of Diminishing Marginal Returns state? A: The Law of Diminishing Marginal Returns states that as more and more units of an input are added to a fixed amount of other inputs, the additional output produced from each new unit of input eventually decreases.
Q: Can Marginal Product be negative? A: Yes, Marginal Product can be negative if adding an additional unit of input leads to a decrease in total output. This typically occurs when there is overcrowding or overuse of the input.
Q: How is Marginal Product used in decision-making? A: Firms use Marginal Product to determine the optimal level of input utilization to maximize efficiency and profitability. By analyzing marginal products, firms can decide whether to increase or decrease the use of an input.
Q: How does Marginal Product affect resource allocation? A: Marginal Product helps in the optimal allocation of resources. By comparing the marginal products of different inputs, businesses can allocate resources to where they are most productive.
