When it was almost a minute to ten o'clock, Professor Tao Xuewei came to the classroom on time, he did not bring textbooks and lesson plans, but walked in with a huge teacup.

The classroom, which was still a little noisy, immediately quieted down, which shows that Tao Xuewei is very respected by the students.

Tao Xuewei is of medium height, thin and thin, with a parted head, wearing a pair of huge black-rimmed glasses on his face, dressed very plainly, and his clothes are obviously still popular in the early eighties, but now they are obviously outdated.

However, Tao Xuewei's spirit is very good, and his face is full of calm and confident smiles.

Tao Xuewei stood on the podium and first looked around at the classmates in the classroom, but because there were too many people in the classroom, Tao Xuewei didn't see Chen Mingyu, he smiled slightly and said, "Before starting the class, I'll tell you a story." A banker's son asked his father, 'Dad, the money in the bank belongs to customers and depositors.' So how did you earn your house, Mercedes and yacht? The banker said: 'Son, there's a piece of fat in the fridge, bring it.' The son brought it. "Put it back again." Dad said. After the son put the pork back in the refrigerator, he asked, 'What does this mean?' The banker said, 'Do you see oil on your fingers?' That's where our houses, Mercedes Benzes and yachts come from'. ”

The classroom erupted in laughter.

After everyone's laughter stopped, Tao Xuewei smiled and asked, "Students, what does this little story illustrate?" ”

As soon as Tao Xuewei's words fell, He Gang was afraid that others would take the lead, so he shouted at the top of his voice: "Banks make money through interest!" ”

Tao Xuewei looked at He Gang, and just wanted to speak, when he suddenly saw that it was Chen Mingyu sitting next to He Gang, and his eyes couldn't help flashing a look of surprise, but he quickly regained his composure, and did not open his mouth to talk to Chen Mingyu, but just smiled and nodded to Chen Mingyu.

Chen Mingyu also smiled and nodded in response.

Tao Xuewei said: "What He Gang just said is right, banks make profits through interest, if you are more accurate, banks actually make profits through interest differences. This is also easy to understand, for example, if you deposit 100 yuan in the bank, the interest rate is 5%, and the bank lends this 100 yuan to others, the interest rate is 10%, and the interest difference is the profit earned by the bank. ”

After saying this opening remark, Tao Xuewei picked up the chalk and turned around and wrote the five big characters "Homo Economicus Hypothesis" on the blackboard, then turned around and said: "Today, I will discuss the concept of 'Homo Economicus Hypothesis' with my classmates. First of all, let me tell you a story. ”

"There was a woman who ran an ad in a New York newspaper for a BMW for a dollar, and the people who saw the ad didn't believe it, because it was impossible to buy a BMW for a dollar, and they all thought it must be another 'fraudulent' advertisement from some company. Days passed, but no one called the woman. Jim, a young man who had just graduated from college, saw the advertisement, believed it, called the woman on the advertisement, and went to the woman's house with a dollar full of hope. Jim asked, 'Why does this BMW sell for only one dollar?' The woman said, 'Because my husband has died, all his possessions belong to me, but this BMW belongs to him and to his lover.' According to his will, the car was to be auctioned, and all the money from the auction belonged to his mistress, so one dollar was enough. Soon they got the formalities done, and Jim only paid a dollar, and the BMW belonged to him. ”

After telling this story, Tao Xuewei picked up the teacup and took a sip of water, and then continued: "The economic man hypothesis, also known as 'rational economic man', is the most fundamental assumption in economics. It can be said that the whole edifice of economics is based on this assumption. This hypothesis was first proposed by the British economist Adam Smith. He believes that people's behavioral motivation is rooted in economic incentives, and that people should strive for the greatest economic benefits, and work is to obtain economic rewards. To do this, it is necessary to use money and power, and the manipulation and control of the organization to make employees obey and work for it. This hypothesis originated in hedonism and was formed by the influence of rationalism in the 19th century, which was proposed by Shane in "Organizational Psychology". This hypothesis holds that all human actions are aimed at maximizing the satisfaction of one's own interests, and that work is for the purpose of obtaining economic rewards. As an individual, no matter what position it is, its essence is the same, that is, to pursue personal interests and meet the maximization of personal interests as the greatest motive, and hope to pay as little as possible to obtain the maximum harvest, for which you can do whatever it takes. Just like Jim mentioned in the previous story, he is happy to buy a BMW car for one yuan, and does not care whether the woman who sold the car loses money, this is his own position to pursue the maximization of personal interests. And the woman who sold the car, in order to take revenge on her husband's mistress, took advantage of the loophole in her husband's will to sell the BMW for one dollar, which also maximized her own interests. It is important to note here that profit maximization is not just about monetary profit maximization! ”

After listening to Tao Xuewei's in-depth explanation, Chen Mingyu, who sat down, felt very rewarded!

Although Chen Mingyu was quite successful in business in his last life, and he naturally studied how to do business, he also had some understanding of economics, but his understanding of economics was mainly obtained through his hard work in the business world and through practice, but he had no theoretical basis.

Just like Tao Xuewei just said, the "economic man hypothesis", the most basic concept in economics, Chen Mingyu has never heard of it.

These economic theories do not seem to be of substantial help to doing business, but in fact, when making some important decisions, in a subtle way, these economics can still play a great role, and as the business gets bigger and bigger, these theoretical things will play a greater role!

In particular, Chen Mingyu is now determined to develop in the official and business circles, especially in the officialdom and supplemented by the business community, and is still in such an era of deep change, it is even more important to study and learn some economic knowledge.

This is also the main reason why Chen Mingyu wants to come to Qingjiang University to sign up for correspondence courses.

Tao Xuewei continued: "In the eyes of economists, all people are rational economic people, that is, rational people who unremittingly pursue their own maximum satisfaction. According to this assumption, it is clear that all homo economicus is self-interested, and each person pursues the maximization of his own interests as his own pursuit. When a person is faced with a number of different opportunities in economic activities, he always tends to choose the one that brings greater benefits to himself. However, self-interest is not exactly the same as selfishness. I'll give you the example of a devout believer who was inspired to do good, and he put this desire into practice. When others are happy because they have been helped, he himself is happy. In this case, the believer's motivation to help others is to maximize his own happiness, which shows that he is self-interested, but it cannot be said that he is selfish. ”

Tao Xuewei then explained the concept of "Homo economicus hypothesis" from several other angles, his explanation was simple and humorous, and from time to time mixed with a very interesting story, so that everyone could listen to it with relish and understand this knowledge point.

Chen Mingyu couldn't help but sigh secretly, his cousin is indeed very good at lecturing!

In addition, Chen Mingyu also found one point, that is, in the process of giving lectures, Tao Xuewei successively said five short stories for example, but without exception, the protagonists of these five short stories are all foreigners, and the background is also placed abroad, and there is no example with domestic people and things as the background.

From the perspective of being easy for students to understand, if Tao Xuewei uses domestic people and things as examples, it will naturally make students feel more intimate and may be able to understand more profoundly.

But Tao Xuewei deliberately did not do so.

Chen Mingyu secretly speculated that the reason why Tao Xuewei did this may be because he is still a little afraid of the ideological field, although since Deng Gong's speech on the southern tour, the whole country has begun to make it clear that the controversy in the ideological field will be put aside and the economy will be developed wholeheartedly.

However, the ideological field is still something that everyone does not dare to take lightly, after all, the Great Movement has only been more than ten years in the past, and people of Tao Xuewei's age have personally experienced it, and they must have deep feelings

Not to mention, just a few years ago, many owners of private enterprises in townships and towns, worried that they would be charged with "speculation," voluntarily handed over the enterprises they had worked so hard to set up to the government or collectives.

At least, judging by the current situation, there is indeed a way to go if people want to completely break free from the shackles of the ideological sphere.

About an hour later, Tao Xuewei's class was over, and the students left the classroom one after another.

He Gang was still angry because of Chen Mingyu's previous sarcasm towards him, and at this time he said excitedly: "Classmate, isn't your economic theory very good?" Do you dare to discuss with our Professor Tao? ”

Chen Mingyu didn't bother to pay attention to him at all, and was simply indifferent to his provocation.

At this time, Tao Xuewei stepped off the podium, beckoned to Chen Mingyu, and said with a smile: "Mingyu, why did you come here?" ”

He Gang saw that Tao Xuewei actually knew Chen Mingyu, and couldn't help but glance at Chen Mingyu in surprise, feeling that this person was really a little unfathomable, so he no longer dared to provoke, picked up his textbook, said hello to Tao Xuewei and Su Yuewen, and left the classroom in a gloomy manner.
