How do you find marginal productivity?

The marginal product formula can be ascertained by calculating the change in quantity produced or change in production level and then divide the same by the change in the factor of production.

### What is the formula for finding the marginal product?

The formula for a marginal product can be derived by dividing the increase in production output (ΔY) by the increase in variable input (ΔI). Mathematically, it is represented as, Marginal Product = Increase in Production Output (ΔY) / Change in Variable Input (ΔI) Further, the formula for a marginal product can be elaborated into

### What is an example of marginal product?

A marginal product is the incremental change in output attributed to a change in any single input item. For example, marginal product may be the increased number of products produced with the addition of one extra worker on a production line.

What is the marginal product of Labor?

Marginal product of labor. In economics, the marginal product of labor (MP L) is the change in output that results from employing an added unit of labor. It is a feature of the production function, and depends on the amounts of physical capital and labor already in use.

How do I calculate marginal revenue?
