The Law for Diminishing Marginal Returns
- As use of an input increases in equal increments, a point will be approched at which the resulting additions to output decreases (that is MP declines).
- When labor input is small, MP increases because of specialization.
- When labor input is large, MP decreases because of inefficiencies.
* The Law of Diminishing Marginal Returns
- Can be used for the long run decisions to assess tradeoffs of different plant configurations
- Assumes that the quality of variable input is constant
- Explains declining MP, not essentially a negative one
- Assumes a constant technology
