This is due to the rise in costs per unit.

The excess in the variable factor now hurts the whole production process. Stage 3: Negative returnsĮxcessively adding to the variable input after the point of optimum production will eventually lead not only to a decrease in efficiency but even to a negative return of production. Adding more units of the variable factor after this point will lead to the overall output starting to diminish. Optimum production is set somewhere within this stage. This process culminates with the product reaching its maximum value, meaning that the marginal product becomes zero. However, during this stage, the total product increases at a continuously decreasing rate. Stage 2: Diminishing returnsĪs more units of the variable factor are added, the overall production will continue to increase. Therefore, adding more units of the variable factor will use the fixed factors more efficiently and increase production. Initially, adding to one production variable is likely to improve the output as the fixed inputs are in abundance compared to the variable one. When all the prerequisites are met, meaning that one input varies while all others stay the same, the law of diminishing returns states that production efficiency will go through three stages: Stage 1: Increasing returns It was originally applied to agriculture, but over time it has been extrapolated to other industries. The concept was further developed by economists like Thomas Robert Malthus and David Ricardo. The history of the law of diminishing returnsĪnne-Robert-Jacques Turgot was the first economist to describe the law of diminishing returns in his 1770 French treatise “Reflections on the Formation and Distribution of Wealth”. This eliminates production situations where some or all inputs vary proportionately to each other. Only one input must vary, while others remain constant at all times.

This would negate the premises of the law of diminishing returns by changing more than one production variable. Changing the technological tools used in production would change the marginal and average cost and value of a product. For it to be valid, some assumptions need to be made:Īll the technology involved is constant.

The law of diminishing marginal returns states that additional inputs will eventually lead to a negative impact on outputs. Related: The Value of Increasing Your Business Vocabulary How does the law of diminishing returns work? It’s typically valid on a short-term basis because over longer periods it is virtually inevitable that even fixed factors of production will become variable. It’s also called 'the law of increasing costs' because adding one more production unit diminishes the marginal returns and the average cost of production inevitably increases. The law of diminishing marginal returns states that in any production process, a point will be reached where adding one more production unit while keeping the others constant will cause the overall output to decrease. In this article, we'll explain what the law of diminishing returns is and how it works with examples. Finding the right balance between factors of production is essential, but it takes knowledge and effort. Regardless of the nature of the company, understanding the law of diminishing marginal returns will have a direct impact on its efficiency. The law of diminishing marginal returns is one of the fundamental principles of economics and is important for finding the right balance in production within an organization.
