What Is the Marginal Zone?

Margin refers to the meaning of margin, extra, and append. It is used to reveal the dynamic functional relationship between two economic variables with causality or correlation. When the independent variable in an economic function changes in the quantity of a small unit, the corresponding quantitative change of the dependent variable is called the marginal value of the dependent variable. ^[1]

4. The term "marginal" is common in economics, and many people find it difficult to understand. In fact, this is like a layer of window paper, and there is nothing mysterious when broken. Economists divide the various variables studied into independent variables and dependent variables. The independent variable is the amount of initial change, and the dependent variable is the amount of change caused by the change of the independent variable. Marginal analysis is to analyze the relationship between changes in independent variables and changes in dependent variables. The amount of change in the dependent variable caused by the change in the independent variable is called the marginal amount. When considering a decision, it is important to consider the marginal quantity, so a marginal analysis method should be used.
