# Marginal homogeneity

## Marginal homogeneity :

Marginal homogeneity is a property of a function that indicates that the marginal value of the function remains constant as the input variables change. In other words, it means that the marginal cost or marginal benefit of a function does not change as the input variables change.
For example, consider a company that produces two products, X and Y, using two inputs, labor and capital. Let’s say that the marginal product of labor for product X is 10 units and the marginal product of labor for product Y is 20 units. This means that for each additional unit of labor used, the company will produce an additional 10 units of product X and 20 units of product Y.
Now, let’s say that the company decides to increase the production of product X by using more labor. As the company increases the labor input, the marginal product of labor for both products will remain constant. This means that for each additional unit of labor used, the company will still produce an additional 10 units of product X and 20 units of product Y.
Another example of marginal homogeneity can be seen in the law of diminishing marginal utility. This law states that as a person consumes more units of a particular good, the marginal utility (satisfaction) derived from each additional unit will decrease. For example, a person may derive a high level of satisfaction from consuming the first slice of pizza, but as they continue to eat more slices, the satisfaction derived from each additional slice will decrease. This means that the marginal utility of each additional slice of pizza remains constant as the person consumes more slices.
In conclusion, marginal homogeneity is an important concept in economics as it helps to understand how the marginal value of a function remains constant as the input variables change. This property is observed in a variety of economic situations, such as the production of goods and the consumption of goods, and helps to explain how individuals and firms make decisions in response to changes in their circumstances.
