The next day, Lecture Hall 1.

With a stack of twelve-page papers, Professor Krugman, dressed in formal attire, stepped onto the podium.

Although this was supposed to be done by Xiaotong, she was dismissed on the grounds that she had no experience in giving presentations at large conferences and could not fully convey her brother's research results to the economics community.

In fact, it doesn't matter who comes to power to do all this work.

Because she's already decided.

Glancing around at the audience, which had gradually quieted down, Professor Krugman cleared his throat and spoke in a steady voice.

"I'm sure many of you here have heard about yesterday's briefing, and even were there themselves."

"Professor Joseph has made a very complete description of the Lu-Bewley model, although there are some omissions and misunderstandings, but at the end of the presentation, those omissions are also added."

"And I don't have much more to say about the Lu-Bewley model. In fact, it shouldn't have been me standing here today, but Professor Lu, who really completed this work. ”

Hearing the last sentence, a whisper sounded in the audience.

"What does Professor Krugman mean?"

"Did Professor Lu do something again?"

"If I'm not mistaken, the topic of this conference should be to discuss the application of the Lu-Bewley model to macroeconomics."

It seems that Professor Krugman made an impromptu change and abandoned the paper he had intended to publish...... Is he planning to publish any new results for Professor Lu? ”

Looking at the commotion in the lecture hall, Professor Krugman gave a heavy kiss to his throat and motioned for the audience to stop talking.

When the lecture hall was quiet again, he continued to speak in a clear voice.

"Just yesterday afternoon, Professor Lu revised his research results and left us with a model that is better than the Lu-Bewley model."

"One might wonder what can be done in an afternoon. In fact, just a dozen hours ago, I was skeptical......"

"Until I actually read the paper."

After Professor Krugman said this, many people in the lecture hall had disbelief on their faces.

Except, the people who were in this lecture hall yesterday......

At this point, Professor Krugman paused for a moment, his gaze resting on the face of Professor Joseph, who was sitting in the front row, for a few seconds, and then turned his gaze to the audience and continued.

"Please don't worry, I'll show you this improved Lu-Bewley model soon."

"Please listen carefully."

……

With his back to the audience, Professor Krugman used the marker pen in his hand to write on the whiteboard line by line according to the content of the paper, and added detailed descriptive language based on his own understanding of the Lu-Bewley model and his understanding of the paper.

Although the equations displayed on the whiteboard at this moment are only the tip of the iceberg of this model, many scholars who are good at using mathematical tools here have clearly felt the superior performance of this improved Lu-Bewley model compared to the previous model.

This is both an academic intuition.

It is also the experience accumulated through long-term research on macroeconomics.

Especially Professor Joseph.

Listening and watching carefully in the audience, at this moment, his face was both shocked and relieved.

Now he finally believed that the man was really not joking.

Being able to study these things in an afternoon, this guy's mathematical attainments have stood at the apex of all the scholars he knows......

And it's not just about the understanding of the math itself.

This ability to use mathematics as a tool and skillfully apply it to completely different fields to solve real problems is terrifying!

I'm afraid even the late math genius John Nash couldn't have done it better......

"Mathematics changes science......" Professor Joseph, who was muttering to himself and staring at the equation on the whiteboard, suddenly shook his head with a smile, "...... No wonder he can boast of such a sea port. ”

ァ新ヤ~(8)~1~Chinese 網ωωω.χ~8.~1zщ.còм

"Hehe, with his ability, he is modest."

It's not just about changing science.

It's a redefinition of science!

At the very least, it redefined his understanding of mathematical economics in his mind......

At the same time, Professor Krugman, who was standing on the podium, also stopped the marker pen in his hand.

After re-glancing at the paper in his hand, comparing the contents of the whiteboard to make sure that there were no omissions or clerical errors, he turned to look at the audience in the lecture hall.

"Any questions?"

There was silence in the audience, no one spoke, and no one raised their hands.

Glancing at the silent audience, Professor Krugman was sure that he had made it clear, and he nodded his head.

"That's all for ......"

Just as he was about to put down the marker, a hand suddenly trembled in the audience.

"Wait a minute!"

Just as everyone was looking at him, the young scholar who stood up scratched his cheek in embarrassment, and spoke quickly.

"I don't have a question to ask, just about the model...... How do we name it? It has to be different from the original Lu-Bewley model, right? ”

That's a good question.

There was a lot of discussion in the lecture hall, as if the issue was being discussed.

Professor Krugman, who heard this question, was also slightly stunned.

It seems that in this paper, there is really no name for this model......

Just like the original paper on the Lu-Bewley model, the name Lu-Bewley model is a default when other scholars discuss this issue.

It seems that Professor Lu does not seem to have much enthusiasm for naming research results in the field of economics.

Thinking of this, Professor Krugman smiled helplessly and shook his head, cleared his throat after thinking seriously for a while, and tried to propose.

"Why don't you add a Joseph to it? After all, Professor Lu himself admitted that he was inspired by Professor Joseph's presentation——"

He was halfway through this sentence when he was interrupted by a voice that could not help but speak.

"I don't deserve it."

In the midst of everyone's astonishment, Professor Joseph, who was sitting in the front row of the lecture hall, suddenly stood up, unceremoniously interrupted Professor Krugman, paused for a moment and continued, "Moreover, I don't want to be counted as a 'false counterexample' to later people's contributions to this model. ”

“…… Uh, that's not what I meant. Seeing Professor Joseph's expressionless face, Professor Krugman, who didn't want to offend people, quickly explained, "This is just for the sake of distinction, not as a counterexample." ”

Ignoring Krugman's explanation, the white-haired old man stared at the equation on the whiteboard for a moment, then was silent for a moment.

After that, he spoke.

"As we can see, the improved Lu-Bewley model has departed from the basic framework of the original Bewley model."

"It's a more open, more operable, and more widely applied economic model."

"Therefore, I propose to name it in a completely new way...... i.e. the L-Z model. ”

There was a commotion at the report venue.

The scholars who sat in the room and held the supporting views nodded their heads in agreement.

Although there are also some people who are expressionless and noncommittal about the name, they also have a little deep thought in their eyes because of this sentence, as if they are seriously thinking about something.

Sitting in the audience, looking at the back of the reinvigorated figure in front of him, Professor Andes nodded approvingly.

"Worthy of Joseph Stiglitz, it seems that yesterday's incident touched him a lot...... Although I am not qualified to judge him, I think his achievements in economics can be taken to a higher level after this conference. ”

Sitting next to Professor Andes, Wesel listened to the big guy talk about "yesterday's incident", and the whole person was confused.

In the end, he couldn't resist the curiosity in his heart and asked.

"Professor Andes, may I ask...... What really happened yesterday? ”

"You weren't there yesterday?" Suddenly remembering something, Professor Andes showed a sudden expression, "Oh, I seem to remember, you really didn't seem to be in the lecture hall yesterday. ”

Wissell swallowed and asked, "So what the hell is going on?" ”

"It's nothing, it's just a pity, you probably missed one of the most exciting presentations of this macroeconomic forum."

At this point, looking at the look of remorse that gradually appeared on the doctoral student's face, Professor Andes smiled maliciously, paused for a moment and then added.

"Of course, it could be the best of the year."
