Chapter 944: Do one and a half things (Mon./Four.)

One hour!
Professor Joseph's pupils dilated sharply, and his face was filled with an incredible look.
It took him years of research to complete the Dixit Stiglitz model with his collaborator Dixit, and it was not until 1977 that he monopolized the monopoly competition and the diversity of optimal products. "In the thesis titled, and thus caused the shock of the entire economics community, 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 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 work ...
However, Lu Zhou now told him that he completed the entire -bewley model in just one hour? !!
This is simply talking!
Even if this model is based on the existing bewley model framework, it takes a one hour to improve such a complicated and complicated economic model into such a concise appearance, it is too scary!
One hour……
Not even enough for his students to fully understand the stuff.
"You must be kidding ..." Eyes stared at the formula on the whiteboard, Professor Joseph said stiffly with a voice like a nightmare.
The subject's direction 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 returned to God, there were only rumbling discussions, unbelievable calls, and exclamations like "god!" And "jes-christ!" In the entire lecture hall.
And the man who stood on the podium and wrote the equations ...
It's been long gone.
...
After coming out of the venue.
Lu Zhou, who closed the door smoothly, faintly heard the noise of restlessness across the door.
And the sound of this sound seems not to be small, even the soundproof door can't be sealed.
"So surprised?"
He wasn't bragging, but it only took an hour.
He murmured in a low voice, realizing that if he continued to stay here, he might be a little terrible. He could not help but quicken his pace and walked away from the lecture hall.
However, just as his forefoot passed by the back door of the first lecture hall, a young lady with short black hair who looked like he was only about 24 or 45 years old was holding a book and a note. Come out.
"Lu Shen! Can I worship you as a teacher?" A little star flickered in her eyes, and a flashing body blocked Lu Zhou's way, she said with an excited voice.
Looking at the open back door, and at the adored young lady, Lu Zhouton said with a headache.
"Are you studying economics? I don't know anything about this stuff. It's better to find a more suitable mentor--"
There was no movement, the younger sister took a step forward, her voice was even more excited.
"Just two minutes ago, I was deeply impressed by your appearance on the stage! I finally understood where the future of economics is! I also deeply understood my shortcomings, me, me and me! I want to follow You learn math! "
Lu Zhou "... ????"
Is this guy listening to someone?
Seeing that the crowd was gradually coming out of the back door, Lu Zhou knew that he might not have a chance if he didn't make a choice, so he took a deep breath and said.
"Sorry, you are a good person!"
Miss Sister "???"
After all, without giving the young lady time to react, Lu Zhou quickly walked away from her and walked towards the elevator.
Just kidding, he runs for half an hour every morning. Even in the heyday, he can't catch up with even a British journalist, let alone a few scientific research dogs who have been hollowed out by the thesis.
"Well, wait a minute, Lu, Lushen! Don't run ~~"
Looking at the elevator door that was slowly closing, and the younger sister who was humming behind, she pressed the land boat with the closing button, and her mouth was slightly curved.
"too weak."
A click.
The elevator doors closed and began to move upwards.
Several people in the elevator looked at each other, looked at the man standing in front of the elevator door, and then exchanged aggressive look.
In the end what happened?
...
Although he did not open a room to check in at the hotel, he could use the hotel elevator if he had a special access card in exchange for an invitation letter.
Arrived on the floor where the Executive Lounge was located, and walked to the front desk to show the card in the lower hand. Then, led by Miss Waitress, a card farthest from the door, near the window to the left and back to the bookshelf Get seated.
"What would you like to drink?"
"Just give me a cup of coffee ... give me a few more pieces of paper."
"A4 paper is OK?"
"can."
"Good sir."
After asking about Lu Zhou's needs, the waiter and sister turned around and left.
He pulled the phone out of his pocket and put it on the table. Lu Zhou, who opened the lock screen, glanced at the time.
It's two o'clock in the afternoon, and there is still a short time before the cafeteria opens.
"Should it be enough?"
Staring at the time on the phone, Lu Zhou murmured to himself.
Just then, the waiter just came back with a stack of papers.
"I'll get the a4 paper you asked for, and the coffee will have to wait for a while."
Lu Zhou nodded and thanked him, and said casually after receiving the paper, "It's okay. I don't need to worry about coffee. I just need to deliver it."
With paper, pens are also available.
He picked out a stick from his pocket and looked at the most pleasing souvenir. Lu Zhou filled the ink bag with it, then held the pen on the paper and tapped it slightly. After thinking about it for a moment, he wrote it.
In the previous report, he was not completely incomprehensible.
Although there is no reserve of economic knowledge in his memory, combining the information provided by Xiaotong previously, in the content explained by Professor Joseph, he basically applied the -bewley model to economics, and The economics community has a deep understanding of the definition of the -bewley model.
It was after knowing these things that he realized that Professor Joseph's misunderstanding of the -bewley model was not accidental.
It can even be said that the error was not entirely on him.
This situation is common for applied mathematics research.
Some things are obvious from his point of view, but for scholars in other fields who are not engaged in mathematical research, it is these things that are obvious to him ~ EbookFREE.me ~ is the most difficult to understand of.
"... Professor Krugman is right, the -bewley model has room for further improvement, not only in the mathematical sense but also in the economic sense."
Arranging in his mind what he heard at the conference, Lu Zhou regarded the entire subject as a mathematical modeling topic, focusing on the new understanding of the -bewley model that he produced during the lecture, one line Written on a line of paper.
Soon, a sheet of a4 paper was full.
I glanced at the results that I had spent about ten minutes writing, and Lu Zhou, who had completely thought out the thoughts, gradually evoked a smile.
"Although it is not particularly interesting, but now that we have studied this, we still have done half of the work ..."
...
It turns out that when people enter a state of concentration, time tends to pass quickly.
I do not know when it started, the sky outside the window has gradually become yellow.
The mobile phone on the table shook slightly, and a line of messages popped up.
Xiao Ai [Master, there is a new mail ~ (??????) ??]
After stopping the pen in his hand, Lu Zhou glanced out of the window and asked casually, "Is it from Professor Krugman?"
Xiao Ai [咦? It is indeed the owner, totally guessed! (???)】
Lu Zhou "What did he say in the email?"
Xiao Ai [He asks if you have time for dinner together. ⊙ ▽ ⊙】
Shaking the dozen or so sheets of a4 paper that were almost full, almost the last page that could be written, Lu Zhou said after thinking for a moment.
"Reply a letter to him for me."
"If he's willing to wait until seven o'clock, I'll make an appointment."
