What economics did Zipper say Professor Xue talked about that impressed you?

What impressed me about economics is probably that Professor Xue made me understand the tragedy of monopoly, rent-seeking and public goods in plain language.

When Professor Xue went to Qipa to talk about it, the topic was: Qipa Planet invented a chip implanted into the future human brain, which realized the knowledge sharing of all mankind. The pros and cons are for and against the birth of this invention respectively. The teacher is positive and Professor Xue is negative.

Let's start with Mr. Cai's speech. Mr. Cai cited an example of a pharmaceutical factory developing anticancer drugs to support his point of view. Indeed, showing specificity? Can reduce the loss that monopoly brings to society, but the biggest harm that monopoly brings is often not the unnecessary loss it brings to the total surplus of society, but it is accompanied by it? Rent seeking? The resource consumption caused by the phenomenon. Professor Xue vividly illustrates this truth with an example. He asked the audience present: If there is a piece of gold outside 100 meters, you run over and get it, and it is yours. Are you running or not? ? The audience nodded unanimously. Professor Xue went on to explain: If 100 people run for this gold medal, it is obvious that only one person will get it in the end. Among them, the hard work of the other 99 people is a meaningless loss. The accompanying running of these 99 people mentioned by Professor Xue is the resource dissipation caused by social rent-seeking behavior.

Another way to solve this social problem is to rely on enterprises or individuals to show their particularity. Teacher Xue followed the example of chasing gold and asked: If I told you that Bolt was running with you, would you still run? ? The audience gradually recoiled and shook their heads. This is actually a way to discourage other enterprises from competing with themselves from the beginning, because they know that the same low cost or sufficient strength can't compete with them. One of the most effective ways for many enterprises to gain market monopoly position is to apply to the court for an injunction against other enterprises. As long as an enterprise can prove its inherent advantage of monopolizing a certain industry, the court will often choose to issue an injunction as soon as possible to reduce unnecessary losses caused by rent-seeking by other enterprises. Because, from the perspective of a decision-maker, he doesn't want to see the cost of social rent-seeking even greater than the total residual loss caused by monopoly. In that case, the total dissipation of social resources will only be greater.

He also gave an example. He said: Kindness will say that as long as there are apple trees, we can all pick them, enjoy them equally. What are the consequences of picking apples like this? Red apples become green apples, green apples become small apples, and there are no apples. ? This is the tragedy of public goods, and the existence of patent pool is to avoid the tragedy of public goods.
