Definition
The Marginal Product Theory of Distribution is an economic theory that explains how income is distributed among the factors of production, such as labor and capital. According to this theory, each factor is compensated based on its marginal product, which is the additional output resulting from one additional unit of the factor, holding all other factors constant. In essence, the theory asserts that:
- Labor receives wages equivalent to its marginal contribution to the product’s market value.
- Capital receives returns that are proportional to its marginal contribution.
Examples
-
Factory Production Line: In a factory, if the addition of one more worker increases the output by 5 units, and each unit sells for $10, the marginal product of labor is $50. Thus, under this theory, the worker should be compensated with $50, reflecting their contribution to production.
-
Capital Investment in Machinery: If an investment in new machinery increases production efficiency, resulting in an additional output worth $5,000, the marginal product of this capital investment is $5,000. Accordingly, the returns to the capital investment should align with this amount.
Frequently Asked Questions (FAQs)
What is the Marginal Product of a factor?
The Marginal Product of a factor is the additional output generated by an additional unit of that factor, keeping all other factors constant.
How does the theory influence wage determination?
The theory suggests that wages are determined by the marginal product of labor. Workers are paid wages equivalent to their marginal contribution to the value of the output they help produce.
Can this theory be applied to real-world scenarios?
Yes, the Marginal Product Theory can be applied to assess how different factors of production, including labor and capital, should be compensated based on their contribution to output in various industries.
Is this theory applicable only to competitive markets?
The Marginal Product Theory assumes competitive markets where factors of production can move freely and wages/capital returns adjust to reflect marginal contributions.
What happens when the marginal product changes?
When the marginal product of a factor changes, its compensation should also change to reflect the new contribution level. For instance, if a new technology increases workers’ productivity, their wages should increase accordingly.
- Marginal Utility: The additional satisfaction or benefit derived from consuming one more unit of a good or service.
- Factor of Production: Inputs used in the production of goods or services, including labor, capital, land, and entrepreneurship.
- Income Distribution: The way in which a nation’s total GDP is distributed amongst its population.
- Production Function: A mathematical function that describes the relationship between input and output in production.

- [ ] How market prices for goods are set.
- [ ] The concept of opportunity costs.
- [ ] Factors influencing consumer behavior.
> **Explanation:** The Marginal Product Theory of Distribution explains how income is distributed among the factors of production based on their marginal product.
### According to the theory, how is labor compensated?
- [x] Based on its marginal product.
- [ ] Fixed hourly wages.
- [ ] Salaries set by labor unions.
- [ ] The average productivity of all workers.
> **Explanation:** Labor is compensated based on its marginal product, which represents its contribution to the market value of the product.
### In the context of this theory, what determines the return on capital?
- [ ] The amount of capital invested.
- [x] The marginal product of capital.
- [ ] Interest rates set by banks.
- [ ] Government regulations.
> **Explanation:** The return on capital is determined by the marginal product of capital, which is the additional output generated by an additional unit of capital.
### What assumption does the Marginal Product Theory of Distribution make about markets?
- [ ] Markets are monopolistic.
- [ ] Markets are oligopolistic.
- [x] Markets are competitive.
- [ ] Markets are highly regulated.
> **Explanation:** The theory assumes competitive markets where factors of production can move freely, and compensation adjusts accordingly.
### How does a change in technology affect the marginal product of labor?
- [ ] It remains constant.
- [x] It can increase the marginal product.
- [ ] It decreases the marginal product.
- [ ] Technology has no impact on labor's marginal product.
> **Explanation:** A change in technology can increase the marginal product of labor by making workers more productive.
### What happens if the marginal product of a factor reduces?
- [ ] The compensation for that factor remains the same.
- [ ] The price of goods decreases.
- [x] The compensation for that factor decreases.
- [ ] Government intervention ensures steady compensation.
> **Explanation:** If the marginal product of a factor reduces, its compensation also decreases to reflect its lower contribution to production.
### Are all factors of production compensated equally in the Marginal Product Theory?
- [ ] Yes, all factors are compensated equally.
- [ ] No, capital is more valued than labor.
- [x] No, each factor is compensated based on its marginal product.
- [ ] Yes, the government ensures equal compensation.
> **Explanation:** Each factor is compensated based on its marginal product, reflecting its unique contribution to the production.
### What does marginal product refer to?
- [ ] Overall production increases.
- [x] Additional output from an additional unit of a factor.
- [ ] Total revenue generated.
- [ ] Average output of all factors combined.
> **Explanation:** Marginal product refers to the additional output resulting from the use of one more unit of a factor, holding all other factors constant.
### Which field of study does the Marginal Product Theory belong to?
- [ ] Psychology
- [ ] Sociology
- [x] Economics
- [ ] Political Science
> **Explanation:** The Marginal Product Theory belongs to the field of Economics as it deals with the distribution of income among factors of production.
### What is a key criticism of the Marginal Product Theory?
- [ ] It oversimplifies the market dynamics.
- [ ] It doesn't account for technological changes.
- [x] It assumes perfect competition which rarely exists in reality.
- [ ] It neglects the role of government policies.
> **Explanation:** A key criticism of the Marginal Product Theory is that it assumes perfect competition, which is rarely observed in real-world markets.
