an hour!

Professor Joseph's pupil zoomed in and his face was filled with disbelief.

It took him several years to devote himself to the research, and then he and his collaborator Dixit completed the Dixit Stiglitz model together. Finally, it was not until 1977 that he put forward the model in the paper titled monopoly competition and the diversity of the best products, which caused the shock of the whole economic circle and directly contributed to the birth of the "new trade theory", even directly for He brought the Nobel Prize in economics in 2001!

No one knows the power of mathematical tools in economic theory better than him!

No one knows better than him how difficult it is to develop a mathematical tool that can be used to analyze economic models and enable him to really play a role

However, Lu Zhou now tells him that it took him only one hour to complete the whole Lu Bewley model?!

This is just talking in a dream!

Even if the model is built on the framework of the existing Bewley model, it's a little too scary to improve such a complicated and complicated economic model into such a simple one in an hour!

An hour

It's not even enough for his students to fully understand it.

"You must be joking..." Professor Joseph said in a dreamy voice, staring straight at the formula on the whiteboard.

The direction of the subject is obvious. Of course, this sentence is for Lu Zhou.

However, it is also clear that this sentence did not reach the ears of the land boat.

When Professor Joseph finally came back to his senses, all that remained in the lecture hall were the uproar, the unbelievable voice, and "God!" 、“Jesus-Christ!” That kind of exclamation.

And the man who stood on the podium and wrote those equations

It's long gone.

……

After coming out of the meeting.

Close the door of the boat, vaguely heard the noise coming through the door.

And the noise seems to be not small, even the soundproof door is almost unsealed.

"As for the surprise?"

He's not bragging, but it's only an hour.

I muttered to myself, realizing that if I stay here, I might have a bit of a bad boat, so I quickened my pace and walked away from the lecture hall.

However, just before he passed by the back door of lecture hall 1, a little sister with short black hair who looked about twenty-four or five years old came out with a book and a note.

"Lu Shen! Can I take you as my teacher? " There were little stars in her eyes, and a flash blocked the way of the boat, she said in an excited voice.

Looking at the open back door and the adored little sister, Lu Zhou suddenly felt a headache.

"Do you study economics? I don't know anything about it. It's better for you to find a more suitable tutor - "

without wavering at all. The little sister stepped forward and became more excited.

"Just two minutes ago, I was deeply impressed by your posture on the stage! I finally understand the future of economics! Also deeply understood my insufficiency, I, I me! I want to learn mathematics from you! "

Lu Zhou: "...??"

This guy, are you listening?

Seeing the crowd coming out of the back door, Lu Zhou knew that he would not have a chance if he didn't make a choice any more, so he took a deep breath and said.

"I'm sorry, you're a good man!"

Little sister:

After all, without giving the little sister time to respond, Lu Zhou quickly bypassed her and flashed in the direction of the elevator.

Jokingly, he runs for half an hour every morning. In his prime, even British journalists can't catch up with him, let alone a few research dogs whose bodies are hollowed out by papers.

"Wait, Lu, Lu Shen! Don't run "~"

look at the slowly closed elevator door, and the little sister who snorted after him. When he pressed the close button on the boat, his mouth curled up a little.

"Too weak."

A click.

The door of the elevator closes and starts to move up.

Several people in the elevator looked at each other, looked at the man standing in front of the door of the elevator, and then exchanged their eyes.

What happened?

……

Although I didn't open a room in the hotel to check in, I still can use the elevator of the hotel with the special access card that I exchange with the invitation letter.

Arrived at the floor where the executive lounge is located, went to the front desk and showed the card. Then, under the guidance of the waiter's little sister, took a seat on a card seat farthest from the door, with the window on the left and the bookshelf on the back."What would you like to drink?"

"Just give me a cup of coffee Give me some more papers. "

"Is A4 paper OK?"

"Yes."

"Yes, sir."

After asking about the need of the boat, the waitress turned around and left with the tray.

I found my mobile phone in my pocket and put it on the table. I opened the lock screen of the boat and looked at the time.

It's just two o'clock in the afternoon. It's not a short time before the cafeteria opens.

"Is that enough?"

Staring at the time on the mobile phone, Lu Zhou whispered to himself.

Just then, the waiter came back with a stack of paper.

"I've got the A4 paper you want. I'll have to wait for the coffee."

Lu Zhou nodded to express his thanks. After taking the paper, he said casually, "it's OK. I'm not in a hurry if I have coffee. Just send it over."

Paper and pen are ready-made.

Pick out the most pleasing souvenir from his pocket. Lu Zhou puts the ink bag on it. Then he holds the pen and lightly points it on the paper. After thinking for a while, he raises the pen and writes.

In fact, he didn't completely fail to understand the previous lecture.

Although there is no reserve of economic knowledge in his memory, combined with the materials previously provided by Xiao Tong, according to the contents explained by Professor Joseph, he basically has a deep understanding of the application of Lu Bewley model in economics and the definition of Lu Bewley model in the economic circle.

It was only after understanding these things that he realized that it was not an accident that Professor Joseph would have a wrong understanding of Lu Bewley model.

It can even be said that the mistake is not entirely on him.

This situation is very common for the research of Applied Mathematics.

Some things are obvious from his point of view, but for scholars in other fields who are not engaged in the research of mathematics, it is these things that are obvious to him that are really the most difficult to understand.

“…… Professor Krugman is right. There is room for further improvement of Lu Bewley model, not only in the sense of mathematics, but also in the sense of economics. "

In his mind, he sorted out what he had heard in the meeting. He took the whole subject as a mathematical modeling topic, and focused on the new understanding of Lu Bewley model that he had produced in the report meeting, line by line, on paper.

Soon, a piece of A4 paper was full.

Looking at the achievements that he spent about ten minutes to write down, he has completed the arrangement of his thoughts completely, and gradually a smile comes up at the corner of his mouth.

"Although it's not a particularly interesting thing, since we've studied it, we'd better finish half of the work..."

……

It turns out that when people get into a state of concentration, time tends to pass quickly.

I don't know when to start, the sky outside the window has been gradually stained yellow.

The mobile phone on the table vibrated a little and a line of messages came out.

AI: [host, there's a new email.]

stop the pen in his hand, and Lu Zhou looks out of the window at the sky and casually asks, "is it from Professor Krugman?"

AI: [eh? It's worthy of being the master. I guess it! (?? *)]

Lu Zhou: "what does he say in the mail?"

AI: [he asked if you had time to have dinner together. Shake the ten or so pieces of A4 paper that are almost full in hand, and it's almost the last page that can be finished. After thinking for a moment, the boat opened up.

"Answer him a letter for me."

"If he would wait until seven o'clock, I would keep the appointment."
