Chapter 894

Although Lu Zhou did occasionally communicate with some economics scholars when he was in Princeton, he was not so familiar with everyone.

He can't talk to him, he has to remember his name, right?

What's more, Princeton is so big, he only stayed for a few years, and he may not have seen this dear friend.

After carefully searching the names in his memory, Lu Zhou couldn't find anyone who could match him. It wasn't until he logged into the academic inquiry website and entered the name that he found out who this man was.

As a result, I don’t know if I don’t search, and the background of the search is not small.

Krugman!

Winner of the 2008 Nobel Prize in Economics!

Expert in international trade, exchange rate and macroeconomics!

The most brilliant stroke in his academic resume is that he successfully predicted the Asian financial crisis in 1997 in 1994. After the outbreak of the Asian financial crisis, his position in the field of economics became more prominent after this prediction, which directly led to his later Received the Nobel Prize in 2008.

But what makes Lu Zhou feel strange is why he contacted him.

The general idea of ​​the email was to ask him when he would be free and would like to chat with him about academic matters face to face via video.

Although he is not very interested in economics, after thinking for a while, Lu Zhou edited a reply letter and sent it.

[Today at 8:00 p.m. Beijing time, if you are free, we can chat. 】

After all, they are also scholars who have won the Nobel Prize, so they still have to give some face.

Anyway, he is also on vacation, and when he is idle, he is also idle...

...

eight pm.

According to the agreed time, Krugman appeared in the camera of the video call.

The professor who met for the first time even omitted the greetings of self-introduction, and said in an impatient tone almost as soon as he got through the video call.

"You don't know how important your research results are!"

Confused by this sudden speech, Lu Zhou was slightly stunned: "...I really don't know, or even which research results you are referring to...Can you tell me?"

Taking a deep breath, Krugman explained.

"The Bewley model has always been at the forefront of macroeconomics. Your improved model... I will call it the Lu-Bewley model for the time being. It not only solves the problem of the Bewley model's huge calculation and cumbersome steps, but the most important thing is to reduce The random error of the model is eliminated!"

Bewley model?

It turned out to be Xiaotong's paper...

After listening to Professor Krugman's description, a dazed expression finally appeared on Lu Zhou's face.

However, it was just a daze, and there was no expression of interest that Professor Krugman expected.

Seeing that Lu Zhou didn't speak, Professor Krugman thought he didn't understand what he meant, so he cleared his throat and continued.

"Let's put it this way, stripping away all the complicated research, there are only two ultimate goals of economics, one is to optimize the efficiency of resource allocation, and the other is to coordinate the interests of society! If we can obtain an accurate model, even as much as possible With an accurate model, we can optimize the allocation of resources to the maximum from the height of civilization! From a personal perspective, we can even predict the future through economic activities!"

Finally reacting to the word predicting the future, Lu Zhou leaned back on his chair.

"That sounds incredible."

Smiling, looking at Professor Krugman on the other end of the video call, Lu Zhou continued, "I don't understand the principles of economics very well, but for chaotic systems... it seems that there has never been any mathematical model that can do it 100% Prediction. Even if I give you a random example, how do you predict the birth of controlled fusion technology? How do you predict its impact on the global economy before it is born?"

"I can't answer this question, but what you said is not the point." Krugman shook his head and continued, "I can tell you that technological progress can theoretically be measured by R&D investment, GDP ratio, etc. The parameters are summarized in the model, even if you can’t understand it, it doesn’t matter, I can tell you clearly that this is a Nobel Prize-level discovery! As long as you continue to study the mathematical improvement of the Bewley model, I’m sure that Nobel Economics The prize must belong to you!"

"But... I have already won the Fields Medal," Lu Zhou shrugged, and continued, "I have also won a Nobel Prize."

The atmosphere in the video was awkward for a while.

Professor Krugman coughed lightly and said persuasively.

"Don't you want to get another one? This is the Nobel Prize..."

"For me, the appeal of the Nobel Prize is not as great as it used to be," Lu Zhou said with a sigh, "You know? Compared with what kind of honor I can get, I am still attracted to those fascinating enough Interested in difficult problems, can you understand the feeling? Dear Professor Krugman."

"..."

Krugman didn't want to answer.

He even wanted to throw the pen on the screen.

A young man in his twenties told him that he no longer pursues honor.

Well, even if this guy does have the qualifications to say that, it's really irritating!

Taking a deep breath, he tried to persuade.

"Isn't the Bewley model enough to arouse your interest? This is also an important enough problem! And it's difficult enough! I can tell you responsibly that it is far more capable of directly changing the world than any purely mathematical research— —”

"That's not necessarily." Interrupting Professor Krugman, Lu Zhou smiled and continued, "Also, improving the Bewley model...or the Lu-Bewley model as you said, it only cost me It's only an hour, no matter how you look at it, it doesn't seem too difficult."

One hour……

Krugman froze there.

Instinct told him that this was absolutely impossible, but the person watching the video didn't look like he was joking or lying.

To put it bluntly, what good is it to lie to him?

Yet an hour improved the Bewley model to such a degree...

This is really too scary!

"Then stop here." Seeing that Professor Krugman couldn't say a word, Lu Zhou glanced at his watch and yawned, "I'm sorry, but I can't help you too much. Princeton has Many excellent mathematics professors, maybe you can take my model and ask them for help."

"Then, goodbye."

The video call is over.

Looking at the blacked out screen, Krugman was silent for a long time, stretched out slightly trembling fingers, and took off the glasses on the bridge of his nose.

Watching the conversation between the old man and Professor Lu, his student Wissel swallowed and said.

"professor?"

Krugman sighed, shook his head and said.

"I can only think of another way."

Princeton does have many excellent mathematics professors, but there are not many professors interested in economics, especially those who are engaged in research in the theoretical field. Many people still have a lot of prejudice against applied disciplines, thinking that studying these things It's a waste of time.

It was not easy for a big cow in the mathematics world to enter this field and made a little bit of results, so he would not let it go easily.

It's like a giant panda that sneaked into the zoo, can you still let you go?

Krugman fell into deep thought, and at this moment, his heart suddenly moved.

At this time, he suddenly remembered that there seemed to be another author in the paper.

It's not Foster who put it together.

He had never heard of this name at all, and he was probably a guy who got lucky.

But the name of the second work...

His eyes gradually brightened, Krugman looked at his student, and immediately spoke.

"Wessel!"

When his name was called suddenly, Wiesel responded immediately.

"I'm...what's your order?"

"Help me write an email. I'll give you the email address in a moment. Just use my name and the recipient's name to fill in Lu·xiaotong..." After a pause, Krugman muttered to himself , "If things go well, we should be able to catch up."

Although the voice of this sentence was not loud, it happened to be heard by Wiesel who was busy editing the email.

Seeing him stunned for a moment, he subconsciously asked.

"Catch up with what?"

"Filling in volunteers, or choosing a mentor," paused, and Krugman continued, "Do you still remember the paper I showed you? Although that paper is only the part of the mathematical model , but being able to sort out the theoretical part completely and allow a mathematician who knows nothing about economics to do such important research is also a rare quality... If I guess correctly, she should not have Decide where to go for a PhD!"

Wiesel hesitated for a moment, and put forward a hypothesis.

"But what if she doesn't plan to continue on the academic path?"

Krugman flatly denies it.

"impossible!"

"It would be absolutely impossible for her to write such an excellent thesis if she hadn't planned to go on the academic path! It's just for graduation, there is no need to do this level at all!"

"Just follow my request and send the email."

"Yes..." Looking at the boss with a serious face, Wiesel could only nod his head dumbly, turned on the computer and started editing the email.

Concentrating on editing emails, this doctor in his thirties couldn't help but feel a whole lot of emotion in his heart.

During the graduation season, others are asking for recommendation letters in various ways, and they want to get recommendations from Daniel. However, this lucky guy is lucky, let alone a letter of recommendation, the Nobel laureate personally sent an email to invite her to read a Ph.D.

This kind of treatment is no one else.

It was even the first time he had heard of such a good thing.

Thinking about it, thinking of his own experience of studying in the past, Weisser felt like a lemon was picked up in his heart, and the overflowing sour smell almost didn't soak into the mail...

Falk!

So envious!
