边际报酬递减规律(生产效率规律)

边际报酬递减规律(生产效率规律)

1. DEFINITION

The law of diminishing marginal returns, also known as the law of diminishing returns, states that as one input variable is increased while the others remain constant, the overall output will eventually decrease. This is because the marginal output, or additional output produced by each additional unit of input, decreases as more and more inputs are added.

2. INTUITION BEHIND THE LAW

The law of diminishing marginal returns can be understood through the example of farming. Let's say a farmer has a fixed amount of land and labor. As he adds more and more fertilizer to the land, the first few units of fertilizer will increase his crop yield significantly. However, as he continues to add more fertilizer, the marginal impact of each additional unit of fertilizer will decrease. Eventually, the farmer will reach a point where adding more fertilizer will actually decrease his crop yield, as the plants become overfertilized and cannot effectively absorb all of the nutrients.

3. EXAMPLES IN BUSINESS

The law of diminishing marginal returns can be seen in many areas of business, such as hiring additional employees or increasing advertising spending. For example, a small business may find that the first few employees they hire greatly increase productivity and output. However, as they continue to hire more employees, the marginal productivity of each additional employee will decrease, as the business reaches a point where there are too many employees and not enough work to go around.

4. IMPLICATIONS FOR DECISION-MAKING

The law of diminishing marginal returns has important implications for decision-making in business and economics. It suggests that there is an optimal level of input usage to maximize output, and that adding more inputs beyond this point will result in decreasing returns. This means that decision-makers must carefully consider the costs and benefits of adding additional inputs, and must be aware of the point at which marginal returns begin to decrease.

5. CRITICISMS OF THE LAW

Despite its widespread acceptance, the law of diminishing marginal returns has been subject to some criticisms. One criticism is that it assumes a fixed technology and production function, which may not hold true in all cases. Additionally, the law assumes that all inputs are equally substitutable, which may not be the case in real-world situations. However, despite these criticisms, the law of diminishing marginal returns remains an important concept in economics and business decision-making.

6. CONCLUSION

In conclusion, the law of diminishing marginal returns, also known as the law of diminishing returns, is a fundamental concept in economics and business. It suggests that as one input variable is increased while the others remain constant, the overall output will eventually decrease, as the marginal product of each additional unit of input decreases. This has important implications for decision-making in business and economics, and decision-makers must consider the optimal level of input usage to maximize output and avoid diminishing returns.
