Today, economists have started considering the law of returns of variable proportions and law of diminishing marginal production as one. According to the law of returns of variable proportions, with the use of fixed means along with the variable menas, the ratio of means get changed and its effect is visible on the production. This effect can be seen on the increasing returns, equal returns and diminishing returns, and the condition of increasing returns is in the initial stage only. Eventually, it means diminishing returns only. Therefore, both these laws are considered to be the same.
