There are two economic phenomena in life and the economic principles involved.

For example, if you accidentally fall into the sewer when you go out in the morning, you may scold: "Who is so incompetent that he even steals the manhole cover?"

Actually, stealing manhole covers is not just a matter of quality. Think about it, most people who steal manhole covers in cities are people from surrounding rural areas. Stealing manhole covers may not be quality, but it is not the root cause. If he has a stable job, he won't steal the manhole cover, because the opportunity cost of throwing the manhole cover is to lose this stable job. As a rational economic man, he will be greater than the marginal income! If he has no job, his opportunity cost is zero, so he will take risks!

In other words, the essential reason for the theft of urban manhole covers is the imbalance between urban and rural development, and rural areas want to share the economic achievements of rapid urban development, not just the low quality!

So, we often say that counterfeiting is just to increase the number of strong counterfeiting? I want to treat the symptoms, not the root cause! Its essence is also the imbalance between urban and rural development. In order to share the economic achievements of rapid urban development, rural areas should narrow the gap between urban and rural areas in order to fundamentally govern! This is the root!

I asked you how many articles you send every day, and he said to send twenty or thirty articles!

Dizzy! You idiot! No wonder MM ignores you!

In fact, this can be explained by economic utility! When MM receives the short message sent to her by the first suitor, there will still be a sense of pride in her heart, no matter how bad the suitor is (this girl knows best), that is to say, the effect of the first short message is the greatest at this time! When you send the second message, the pride that this message brings to MM will be reduced, that is, the second message brings less benefits than the first one! This is the law of diminishing marginal benefits that is often said in economics! Send twenty or thirty short messages, and the marginal utility is already negative for MM! In other words, MM, the text message you sent is disgusting!

We gave him an idea: reduce the number of text messages every day, just send three or four messages a day, but send them once a day.

Why is it that the total utility brought by sending three or four short messages is the greatest, that is to say, the sum of three or four short messages is the greatest, (because the sum of the effects will be reduced in the future), when you send messages in a period of time every day, MM will take receiving short messages as a part of life! What about the back? Why not send it a week late? Because MM will take receiving SMS as a part of her life, she suddenly stopped receiving SMS! She will feel that she has lost something! In economics, it is called buried cost! That is to say, MM didn't receive the text message during this period. If other universities are bored, they will be bored in the past, but they used to receive short messages, so the cost of MM burial is to receive short messages! At this time, MM will think of you in her heart!

That's it!

When you send a message to a MM, you can see how interested he is in you from the time she replies! The sooner you come back, the more interested you are!
