945 Finishing Half Of The Things (1/4)

Chapter 945 Finishing half of the work (14)

One hour!

Professor Joseph's pupils dilated suddenly, and an expression of disbelief was written on his face.

It took him several years of painstaking research to complete the Dixit-Stiglitz model with his collaborator Dixit, and it was not until 1977 that he published it in "Monopolistic Competition and the Diversity of Optimal Products". ", which caused a shock in the entire economics circle, directly contributed to the birth of the "New Trade Theory", and even directly brought him the Nobel Prize in Economics in 2001!

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

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

However, Lu Zhou now told him that he completed the entire Lu-Bewley model in only one hour? !

This is simply talking in sleep!

Even though this model is based on the framework of the existing Bewley model, it is too scary to improve such a complex and cumbersome economic model into such a simple one in one hour!

One hour……

Not even enough of his students to fully understand this stuff.

"You must be joking..." Professor Joseph said stiffly in a sleepy voice, staring straight at the calculations on the whiteboard.

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

However, this sentence obviously did not reach Lu Zhou's ears.

When Professor Joseph finally came back to his senses, there were only sensational discussions, voices of disbelief, and exclamations such as "God!" and "Jesus-Christ!" in the entire lecture hall.

And the man standing on the podium with those equations written on it...

It's long gone.

...

After coming out of the venue.

After closing the door smoothly, Lu Zhou vaguely heard a restless sound coming through the door.

Moreover, the sound seemed to be quite loud, and even the soundproof door could hardly be sealed.

"As for being so surprised?"

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

After muttering something softly, Lu Zhou realized that it might be a bit bad if he stayed here, so he couldn't help but quicken his pace and walked away from the lecture hall.

However, just as he passed by the back door of Lecture Hall No. 1, a young lady with short black hair who looked about twenty-four or five years old was holding a book and a notebook to chase after him. out.

"God Lu! Can I worship you as my teacher?" With little stars in her eyes, she blocked Lu Zhou's way with a flash, and she said in an excited voice.

Glancing at the open back door, and then at the adoring young lady, Lu Zhou said with a headache.

"You major in economics, right? I don't know anything about it, you'd better find a more suitable tutor—"

Without wavering at all, the young lady took a step forward, her tone even more excited.

"Just two minutes ago, I was deeply impressed by your appearance on the stage! I finally understand where the future of economics is! I also deeply understand my shortcomings, me, me! I want to share with you You study math!"

Lu Zhou: "...???"

Is this guy listening to anyone?

Seeing that the crowd was about to pour out from the back door, Lu Zhou knew that if he didn't make a choice, he might have no chance, so he took a deep breath and said.

"Sorry, you're a nice guy!"

Young lady: "???"

After all, without giving the young lady any time to react, Lu Zhou quickly walked aside her and walked in the direction of the elevator.

Just kidding, he has to run for half an hour every morning for morning exercises. In his prime, even a British reporter can't keep up with him, let alone a few scientific research dogs whose bodies have been hollowed out by papers.

"Hey, wait a minute, Lu, God Lu! Don't run away~~"

Looking at the slowly closing elevator door, and the young lady chasing after him, Lu Zhou pressed the door closing button, and the corner of his mouth curled up.

"too weak."

There was a click.

The doors of the elevator close and start moving upwards.

Several people in the elevator looked at each other, glanced at the man standing in front of the elevator door, and then exchanged bewildered glances.

In the end what happened?

...

Although there is no room to check in at the hotel, you can still use the hotel elevator with a special access control card in exchange for the invitation letter.

Arriving at the floor where the executive lounge is located, Lu Zhou walked to the front desk and showed the card in his hand. Then, under the guidance of the waitress, he went to a card that was farthest from the door, with the window on the left and the back against the bookshelf. Take your seat.

"What would you like to drink?"

"Just give me a cup of coffee...and some paper."

"Is A4 paper okay?"

"Can."

"Good sir."

After asking about Lu Zhou's needs, the waitress turned around and left holding the tray.

He took out his mobile phone from his pocket and put it on the table. After unlocking the screen, Lu Zhou checked the time.

It was only two o'clock in the afternoon, and there was still a long time before the cafeteria opened for business.

"Should be enough?"

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

At this moment, the waiter just now came back holding a stack of papers again.

"I brought you the A4 paper you asked for, and the coffee will have to wait for a while."

Lu Zhou nodded his thanks, took the paper and said casually, "It's okay, I'm not in a hurry for the coffee, just send it over when it's ready."

As long as there is paper, there is also a pen.

Picking out the most pleasing souvenir from his pocket, Lu Zhou put the included ink bag on it, then tapped the pen on the paper, and after thinking for a while, he picked up the pen and started writing.

In fact, he didn't understand the previous report meeting at all.

Although he does not have a reserve of economics knowledge in his memory, but combined with the materials provided to him by Xiaotong, and based on the content explained by Professor Joseph, he basically understands the application of the Lu-Bewley model in economics, And the economics community has a deep understanding of the definition of the Lu-Bewley model.

And it was after understanding these things that he realized that it was not accidental that Professor Joseph had a wrong understanding of the Lu-Bewley model.

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

This situation is common for research in applied mathematics.

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

"...Professor Krugman's conjecture is indeed correct. There is still room for further improvement of the Lu-Bewley model, not only in the sense of mathematics, but also in the sense of economics."

Arranging in his mind what he had heard at the meeting, Lu Zhou regarded the whole topic as a mathematical modeling topic, focusing on the new understanding of the Lu-Bewley model that he had generated during the report meeting, Write it down on paper line by line.

Soon, an A4 paper was full.

Looking at the results that he spent about ten minutes writing, Lu Zhou, who had completely finished organizing his thoughts, gradually brought a smile to the corner of his mouth.

"Although it's not particularly interesting, but since we've already researched this, we've finished half of the work..."

...

Facts have proved that when people enter a state of concentration, time tends to pass quickly.

I don't know when it started, the sky outside the window has gradually turned yellow.

The phone on the table vibrated slightly, and a message popped out.

Xiao Ai: [Master, there is a new email~()]

Stopping the pen in his hand, Lu Zhou glanced at the sky outside the window, and asked casually, "Is it from Professor Krugman?"

Xiao Ai: 【Huh? As expected of the master, I guessed it right! (*)】

Lu Zhou: "What did he say in the email?"

Xiao Ai: [He asked if you have time to have dinner together. ⊙▽⊙]

Shaking the ten or so sheets of A4 paper that were almost full, and the last page that was almost finished, Lu Zhou thought for a moment, and then said.

"Return a letter to him for me."

"If he will wait until seven o'clock, I will attend."
