City: Me, IQ 300

Chapter 97 Class, not a fan meeting (subscription requested, first change)

The time is Saturday, evening time, electives.

Peking University has always been the first school in the country to eat cake in the curriculum, and Peking University has been involved in the early Internet celebrity training and the later online literature.

At this time, a new economics major was gradually taking shape.

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 along one after another.

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

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

“But since you have come to my course, I think, I can still give you a lesson, but, first of all, this course is the first time to start, you don’t have too many ideas, this itself is applicable, groping.”

Everyone nodded one after another, can come, in fact, the biggest impact is Chen Fan refused Buffett’s invitation, because of the refusal of Buffett’s invitation, so Chen Fan is really full of temptation, too attractive.

Chen Fan put down the document in his hand and said: “Traditional economics, everyone is already familiar, I won’t talk to you here, I’ll just say something dry, I think a lot of models to teach you, I think, or the simplest question is more suitable, for the problem, you to explain, first of all, if you ask idiot questions, 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 time can be mixed.

“What is game theory? And what is economics? ”

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

A girl was called out.

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

Chen Fan called another boy, the boy got up, a little overwhelmed, if the knowledge in the book is not right, then how do he answer this question?

“Is it to make money?”

Hahaha, the room was filled with laughter, and Chen Fan said: “You are right. ”

Groove, right?

Everyone looked at Chen Fan.

“I think that 80% of people think that economics is learning to make money before they know economics, and I can boldly tell you now that economics is to make money, not to make money, what do I do when I study economics?” Do charity? ”

This Chen Fan is a little different.

Wait, this guy is only fifteen years old? 》

The oldest students in our room are twenty-four or five.

Nima, it’s so much worse.

This guy sees better than us?

“Just like me, there are several hundred million things, I myself am not interested in money, or not.”

This guy is pretending, yes, absolutely pretending.

Chen Fan said: “In fact, game theory, in my concept is a tool, economics is a category of distinction, but what, so it is not interesting, let me say so, you learn game theory, you must be proficient in economics, in this way, you can use game theory to live, so what is game theory?” ”

Chen Fan wrote a simple question on the blackboard.

“One night you are at a party and there are a lot of people in the house and you have a great time. At this time, there was a sudden fire in the house, and the fire was too large to extinguish. At this point you want to escape. There are two doors in front of you, the left door and the right door, and you have to choose between them. But the problem is that others are also competing for both doors to escape. If you choose a door that many people choose, then you will burn to death because of the crowded people and the inability to rush out; Conversely, if you choose the less chosen one, then you will escape. Here we do not consider the moral factor, how will you choose? ”

After such a problem is given, these students in the audience probably understand a little, this is game theory.

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

Some students raised their hands.

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

Chen Fan nodded.

Anna listened on the side, she felt that she didn’t seem to need her own help, Chen Fan, this guy, had already led the students to her own rhythm.

“Well, this moral level is the basis for what you are going to learn today, which is some of the related connections between humanities and economics.”

Chen Fan continued: “The basic knowledge of economics, more than thirty categories, these include value, currency, market, etc., you have all learned, if you can’t, forget, I recommend learning the basics first.” ”

Everyone smiled and nodded.

This is the truth.

Elective courses, despise compulsory courses, Chen Fan is not a teacher, will not because of a problem, you ignore the most basic questions to explain to you, what Chen Fan will do is to scold an idiot, are you a pig? What books write, you can also be wrong?

Halfway through the lesson, Chen Fan wrote a simple question on the blackboard.

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

……

Looking at the matrix, Chen Fan said: “You guys use the game theory foundation to do this topic first, give you five minutes, just right, I can drink a sip of water.” ”

Everyone took the book and began to write.

Chen Fan smiled, at this time, a girl raised her head, looked at Chen Fan, and said: “Chen Fan, when are you in love.” ”

Poof.

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

“No, no, no, it’s not economics, it’s asking.”

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

Hahahaha.

Anna couldn’t help but laugh, yes, Chen Fan is only fifteen, you know, the country is measured according to the standard of sixteen years old.

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

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

Everyone lowered their heads and began to write in unison.

Soon, the answer came out.

“For both Company A and Company B, low prices are their advantageous strategy. It can be seen from the table that the dominant strategy of enterprise A is 10 yuan, because no matter what strategy B adopts, enterprise A can obtain more profits than the price of 15 yuan.

If enterprise B prices 10 yuan, enterprise A can make a profit of 800,000 yuan if it sets 10 yuan, and only 300,000 yuan if it is priced at 15 yuan; If Company B sets a price of 15 yuan, Enterprise A can make a profit of 1.7 million yuan if it sets 10 yuan, but only 1.2 million yuan if it is priced at 15 yuan. Similarly, the dominant strategy of enterprise B is also a strategy priced at $10.

If enterprise A prices 10 yuan, enterprise B can make a profit of 1 million yuan by pricing 10 yuan, but only 500,000 yuan if it is priced at 15 yuan; If Enterprise A prices 15 yuan, Enterprise A can make a profit of 1.8 million yuan by pricing 10 yuan, but only 1.5 million yuan can be made by pricing 15 yuan. Similarly, Enterprise A’s dominant strategy is also a $10 strategy.

Finally, one of the most likely outcomes is (10, 10), so both sides adopt a low-price strategy.

The girl who asked the question before did have a little talent, and the answer was also very fast.

Chen Fan said: “Yes, in fact, this is the price wheel in Game Theory Sixty-Six, but what needs to be thought about here is humanism, I test you, you say, if you are company A, you need to let the people of company B lose to you in the price battle, what do you do.” ”

The girl was stunned and looked at Chen Fan.

“It’s okay, diverge your own thinking, endless divergence.”

The girl thought for a while and said: “I probably understand what you mean, the price war, without violating the law, can be unscrupulous, if it is me, I will hire a certain person to go to the black B enterprise.” ”

“Well, this is possible, this is very important in economics and humanities.”

“If I were a girl and the other party was a man, I would find someone to let this man not deal with this matter in the short term.”

Chen Fan continued to nod.

“I will try my best to contact the manufacturer and reduce the speed of incoming goods from Company B.”

It’s okay.

“I can probably 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 rational, what we add to it, this in itself is a very serious issue. ’

friendly

The most important condition is that the strategy must be “friendly”, that is, do not betray the opponent before it does. Almost all high-scoring strategies are friendly. Therefore, a completely selfish strategy is only for selfish reasons and will never strike its opponents first.

Get you back

But, Axlaud, he argues, a successful strategy must not be a blind optimist. Always retaliate. An example of a non-retaliatory tactic is always cooperating. This is a very bad option, because “indecent” tactics will brutally exploit such fools.

forgive

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

Not jealous

The last quality is not jealousy, that is, not striving to score higher than your opponent (which is also impossible for a “friendly” strategy, which means that a “friendly” strategy can never get a score higher than your opponent).

Chen Fan wrote down several basic points of human nature.

“These are the weights I want to emphasize today, in the economic game, we need to think not only about the rational situation, but also about the human character itself, I think these cases, you all know.”

“Chen Ou.”

Someone thought about this man’s life.

“Yes, Chen Ou, what is the reason for the failure? Is the price? Or is it a matter of vision? I think he was retaliated against, of course, this is just my guess, after all, even if he has no money, I think he has more money than some of the people who are doing it. ”

“That’s not possible, I have three apartments within the second ring road. ：”

“Students like you will generally be killed, I’m talking about economics, don’t move your ancestors out.”

Hahahaha, everyone laughed.

Chen Fan looked at the big guy happily, wiped off the blackboard, and said: “Then, the game I am talking about now is the love issue that everyone is most interested in, don’t look at me as only fifteen years old, I think, I talk about this, you should be particularly interested.” ”

That’s a must, there’s nothing more exciting than falling in love.

Chen Fan rubbed his temples and said: “In a while, what I say may stimulate your hearts, whether it is a boy or a goddess, you are not allowed to report me, you report me, I will find someone to make you unable to get by, I will also retaliate.” ”

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

“It’s also right to understand it this way, then, let’s start, the first question, why, high school love is ugly.”

？？？？？

Question marks at the end of countless people.
