When browsing through news messages, the words “marginal increase” and “marginal decline” often jump into the curtains. Once upon a time, it was always a fog, and it was hard to see what the term “marginal” meant. Searched for the explanation given by economists: "the marginal is the new addition, what is the new addition? Why do i sound like i'm losing my mind
It didn't come to light until it was read in the ecclesiastical. It turns out that “marginal” is not an inexplicable concept; it is hidden in our daily lives. The marginal effect is that when you're hungry, you eat a third or fourth bag, you eat a regular meal, you drink water..
For a simple example, imagine, you're hungry enough to pay a dollar for a bag. The first bites, and the happiness reaches its peak. After eating one, there's a slight reduction in hunger, but it's not completely eliminated, so you bought another. And that's when you'll find that the second bun is no better than the first, and then the marginal effects start to work. When you get to the third and fourth buns, your desire for the buns gets lighter and you don't even want to spend another dollar on one. At this point, the happiness of eating buns almost disappears, which is a vivid manifestation of the law of marginal decline -- – for every unit of goods we consume, the sense of additional satisfaction will diminish。
So it's probably clear what the marginal effect is. Understanding the marginality, then we can increase our sense of well-being by balancing marginality and marginal cost。
In the case of breakfast, when you realize that eating more buns doesn't bring more happiness, you can save the money to buy a cup of milk tea, which is often much more happy than eating more buns. Alternatively, saving the money that would otherwise have been spent on daily consumption to buy a very expensive diamond parcel is more durable and intense than the sense of happiness and satisfaction that would flow from the continuous purchase of low-cost, homogenous commodities。
Marginality can also adjust the pace and objectives of learning. For example, the increase from 60 to 80 points is relatively easy, and your efforts can quickly lead to a more significant increase in scores, at a time when the marginal effects are higher. However, increasing from 80 to 90 points is much more difficult, and each increase requires more effort, while the results are beginning to be minimal, at a time when marginal costs are rising while marginal effects are decreasing. By the time they hit 100 minutes from 99, the effort was enormous, but the increase in the score was very limited. But even so, we will continue to weigh the pros and cons in the process, making reasonable use of our limited time and energy in pursuit of maximum progress。
Marginal effects, like an invisible but powerful hand, play an important role in every corner of life. Whether daily consumption choices or the energy invested in the learning process, we are unwittingly guided by the principle of marginal balance and the rational allocation of limited resources in our hands, with the expectation of maximizing effectiveness. It turns out everyone's good at marginal balance
