Metropolis: My IQ is 300

Chapter 102

Chapter 97 is in class, not a fan meeting (seeking subscription, first update)

The time is Saturday, evening time, and elective courses.

In opening courses, Peking University has always been the first and the first school in the country to eat cakes. Peking University has been involved in the early online celebrity training and the later online literature.

At this time, new economics majors are gradually being formed.

Chen Fan took the book, stood on the podium, looked at the people in the room, and said, “Aren’t you hot?”

Chen Fan said half-jokingly, and everyone in the audience laughed.

There are many people sitting, and many more people standing.

Everyone seems to be more interested in Chen Fan than in economics.

“But since you have come to take my course, I think I can give you a lesson. But let me say that this is the first time this course is launched. Don’t have too many ideas. This in itself is applicable and groping. ”

Everyone nodded and was able to come. In fact, the biggest impact was Chen Fan’s rejection of Buffett’s invitation. Because of his rejection of Buffett’s invitation, Chen Fan was really full of temptation and too attractive.

Chen Fan put down the file in his hand and said: “Traditional economics, everyone is already familiar with it. I won’t talk about it here. I’ll just talk about dry goods. I think a lot of things to teach you. The model, I think, is the easiest way to do the question. For the problem, you can explain it first. If you ask an idiot question, I think I will curse.”

After speaking, Chen Fan began to write on the blackboard.

The students in the audience recorded.

Writing instead of using a computer, the reason is that you can mix time.

“What is game theory? What is economics?”

Chen Fan looked at everyone in the audience and asked these two questions.

A girl was called up.

“I… I think that game theory should be the use of economics, and economics is a huge discipline, or the study of everything that is related to the development of money is economics.”

With a smile on his face, Chen Fan said: “Your explanation is official, it’s not interesting, think about it again.,”

Chen Fan called another boy. The boy got up and was a little at a loss. If the knowledge in the book is not correct, how should he answer this question?

“Is it to make money?”

Hahaha, a room is full of laughter, Chen Fan said, “You are right.”

Damn it, right?

Everyone looked at Chen Fan.

“I think that before 80% of people know economics, they think that economics is to learn to make money. I can boldly tell you that economics is to make money. If you don’t make money, what do I do when I study economics? ? Do charity?”

This Chen Fan is a bit different.

Wait, this guy is only fifteen years old? 》

The biggest student in our room is twenty-four-five.

f*ck, so much difference.

This guy sees better than us?

“Just like me, there are hundreds of millions of things, and I am still not interested in money.”

This guy is pretending, yes, absolutely pretending.

Chen Fan said: “In fact, game theory is a tool in my concept, and economics is a division of categories, but it is boring to say that. Let me put it this way. You must be proficient in economics to learn game theory. In this way, you can live with game theory, so what is game theory?”

Chen Fan wrote a simple question on the blackboard.

“One night, you were at a party, there were many people in the house, and you had a great time. At this time, there was a fire in the house. The fire was so strong that it could not be extinguished. At this time, you want to escape. There are two doors in front of you. You have to choose between the left door and the right door. But the problem is that other people have to fight for these two doors to escape. If the door you choose is chosen by many people, then you will be crowded and rushed due to the number of people. Don’t go out and burn to death; on the contrary, if you choose something less people choose, then you will escape. Here we don’t consider moral factors, how would you choose?”

After such a question was given, the academic tyrants in the audience probably understood a little bit. This is game theory.

Chen Fan pointed to the moral element on the blackboard and said: “Then, why this moral element should be specifically pointed out and cannot be considered as thinking.”

Some students raised their hands.

“I think this should be because people are different and people are not rational.”

Chen Fan nodded.

Anna was listening, and she felt that she didn’t seem to need her own help much. Chen Fan, this guy, has taken the students to her own rhythm.

“Then, this moral level is the basis for you to learn today, that is, some related series of humanities and economics.”

Chen Fan continued: “The basic knowledge points of economics, more than 30 categories, these include value, currency, market, etc., you have learned all of them, if you don’t know it, forget it, I suggest you learn the basics first. Say it again.”

Everyone smiled and nodded.

This is the truth.

Elective courses and despise compulsory courses. Chen Fan is not a teacher either. You will not ignore the most basic questions to explain to you because of one problem. What Chen Fan will do is to curse an idiot. Are you a pig? What is written in the book, you can also be wrong?

Halfway through the course, Chen Fan wrote a simple topic on the blackboard.

“Assuming that there are only two companies in the market, A and B, and each company can adopt a pricing strategy of 10 yuan or 15 yuan, we can get the benefit matrix as follows:

…

Looking at the matrix, Chen Fan said: “Let’s do this topic with the basis of game theory first. I will give you five minutes, just right, I can drink a sip of water.”

Everyone took their notebooks and began to write.

Chen Fan smiled. At this time, a girl looked up, looked at Chen Fan, and said: “Chen Fan, when are you in love?”

Puff.

Chen Fan sprayed out a mouthful of water, looked at the girl, and said, “This is a very good topic, and this also involves game theory.”

“No, no, this is not economics, this is inquiry.”

Chen Fan said helplessly: “I’m only fifteen, let me go, I’m still a child.”

Ha ha ha ha.

Anna couldn’t help laughing. Yes, Chen Fan is only fifteen. You know, China is measured according to the sixteen-year-old standard.

The girl didn’t want to give up, and said, “I remember, many people in high school are in love, what do you think of this.”

Chen Fan said: ‘This involves a very deep game theory. If you want to hear it, I can talk about it. You can listen to it if you want, but for this question, first of all, I need someone to give me the answer. ’

Everyone lowered their heads and began to write.

Soon, the answer came out.

“Whether for enterprise A or enterprise B, low prices are their dominant strategy. From the table, it can be seen that enterprise A’s dominant strategy is 10 yuan, because no matter what strategy B adopts, enterprise A can get 15 Yuan more profit.

If enterprise B sets a price of 10 yuan, enterprise A can make a profit of 800,000 yuan for a price of 10 yuan, and can only get 300,000 yuan for a price of 15 yuan; if enterprise B sets a price of 15 yuan, enterprise A can make a profit of 1.7 million yuan for a price of 10 yuan, and The price is 15 yuan, but it can only make a profit of 1.2 million yuan. Similarly, the dominant strategy of enterprise B is also a strategy of 10 yuan.

If enterprise A is priced at 10 yuan, enterprise B can make a profit of 1 million yuan at 10 yuan, and can only get 500,000 yuan at 15 yuan; if enterprise A is priced at 15 yuan, enterprise A can make a profit of 1.8 million yuan at 10 yuan, and The price is 15 yuan but it can only make a profit of 1.5 million yuan. Similarly, the dominant strategy of enterprise A is also a strategy with a price of 10 yuan.

In the end, the easiest outcome is (10, 10), so both sides adopt a low-price strategy.

The girl who asked the question before, does have a little talent, and the answer is very fast 0…

Chen Fan said: “Yes, in fact, this is the price wheel in Game Theory Sixty-Six. However, what needs to be considered is humanity. I will test you. For you, if you are a company, you need to let b. The people in the company lost to you in the price battle, what do you do?”

The girl was stunned and looked at Chen Fan.

“It’s okay, diverge your thoughts, diverge endlessly.”

The girl thought for a while and said: “I probably understand what you mean, price wars, if you don’t violate the rules, you can do whatever you want. If it were me, I would hire someone to go to the black enterprise.”

“Well, this is okay. This is a very high proportion in economics and humanities.”

“If I am a girl and the other party is a man, I will find someone to let this man not deal with this matter for a short time.”

Chen Fan continued to nod his head.

“I will try my best to contact the manufacturer to slow down the rate at which the items of company b are paid in.”

It’s also possible.

“Probably I can think so much.”

Chen Fan said: ‘Actually, this is the core of what I want to say, that is, when game theory is no longer sensible, what are we adding? This is a very serious question in itself. ’

friendly

The most important condition is that the strategy must be “friendly”, that is, don’t betray before the opponent betrays. Almost all high-scoring strategies are friendly. Therefore, a completely selfish strategy is only for selfish reasons and will never hit its opponent first.

revenge

However, Axelrod argued that a successful strategy must not be a blind optimist. Always retaliate. An example of a non-retaliation strategy is always cooperation. This is a very bad choice, because the “indecent” strategy will cruelly exploit such fools.

forgive

Another quality of a successful strategy is the need to forgive. Although they do not retaliate, if their opponents do not continue to betray, they will repeatedly retreat to cooperation. This stops the long-term retaliation and counter-retaliation and maximizes the number of points scored.

Not jealous

The last quality is not to be jealous, that is to say not to strive for higher scores than the opponent (this is also impossible for the “friendly” strategy, which means that the “friendly” strategy can never get higher than the opponent’s score) .

Chen Fan wrote down a few basic points of human nature.

“These are the weights I want to emphasize today. In the economics game, we need to think about not only the rational situation, but also the personality of the person itself. I think you all know these cases. .”

“Chen Ou.”

Someone thought of this person’s life.

“Yes, Chen Ou, what is the reason for the failure? Is it the price? It is still a matter of vision? I think I was retaliated. Of course, this is just my guess. After all, even if he has no money anymore, I think he will be better People have money.”

“That’s impossible. There are three suites in my house within the second ring road.:”

“Students like you are usually beaten to death. I’m talking about economics. Don’t move your ancestors out.”

Hahahaha, everyone is smiling.

Chen Fan looked at the big guy happily, erased the blackboard, and said, “So, the game I am talking about now is the love issue that everyone is most interested in. Don’t think I am only fifteen years old. I think, I will talk about this. You should be particularly interested.”

That must be, nothing is more exciting than talking about love.

Chen Fan rubbed his temples and said, “For a while, what I say may irritate your heart. Whether it is a boy or a goddess, you are not allowed to report me. If you report me, I will find someone to make your credit difficult. I There will also be revenge.”

“Hahaha, teacher, is this revenge in economics?”

“That’s right to understand, then, let’s start, the first question, why, high school love is ugly.”

? ? ? ? ?

The question mark at the head of countless people.
