In this case, if we want to increase the same amount of output, we should increase the input of variable production factors. Why increase the input?

In this case, if we want to increase the same amount of output, we should increase the input of variable production factors. Why increase the input?

For example, the original average increase of 10 people a day can increase production of 5 finished products, now only increase production of 3
If you want to increase production by 5, you have to increase more than 10 people

Three preconditions for the law of diminishing marginal returns to work

1. The proportion of production factor input is variable, that is, the technical coefficient is variable. 2. The technical level remains unchanged. 3. The increased production factors have the same efficiency

The relationship between production and cost in microeconomics under the action of diminishing marginal returns

The rising speed of cost is faster than that of output
On the margin, the cost of single production is increasing
Until the marginal cost rises to the marginal income, the output will not increase
