Marginal is the relationship between new input and new output. Linear unit input corresponds to linear unit output is not the state of real life. Since the nonlinear effect is a problem of two directions, it is either decreasing or increasing.

The decline is best understood, the matter of psychological individual correlation, mostly is degressive. Eating watermelon in the summer, eating watermelon is a linear input, the satisfaction is incremental decline. Marginal decline can be used to understand a lot of non-psychological phenomena. The leading shares in the stock are used in this concept, and the leading shares in various industries have mostly outperformed other stocks.

The effectiveness of a single AD is limited, but the impact of successive AD bombings is beyond the current imagination. Reading and learning in many fields is also an example of increasing marginal effect, which means that the boundary value of increasing utility is reached in the current range, which leads to uncontrollable development. The marginal increment in the investment is most notable is the downward situation. Taking personal losses as an example, the downward step loss is actually a process of increasing utility, because the lower the step down, the harder it is. Bankruptcy, for example, is the most marginal damage to assets. Such losses and bankruptcies are not limited to assets.
