Chapter 947

The next day, report hall 1.

With a stack of twelve pages of papers, Professor Krugman, dressed in formal clothes, came to the stage.

Although this was supposed to be done by Xiaotong, it was rejected by her because she did not have the experience of making a report at a large conference and could not completely convey her brother's research results to the economic circle.

In fact, it doesn't matter who will take the stage to finish the work.

Because she has decided.

Looking around at the quiet stage, Professor Krugman cleared his throat and spoke in a steady voice.

"I believe that many of you have heard about yesterday's report meeting, even on the spot."

"Professor Joseph has made a very complete description of Lu Bewley model. Although there are some omissions and misunderstandings, at the end of the report meeting, he also supplemented those omissions."

"I don't have much more to say about the Lu Bewley model. In fact, I should not have been the one standing here today, but Professor Lu who really finished the work. "

At the last sentence, there was a whisper under the stage.

"What does Professor Krugman mean?"

"What else did Professor Lu do?"

"If I remember correctly, the theme of this conference should be to discuss the application of Lu Bewley model in macroeconomics."

"It seems that Professor Krugman made a temporary modification and gave up the paper he intended to publish Is he going to publish anything new for Professor Lu? "

Looking at the newly stormed lecture hall, Professor Krugman kissed his voice heavily and signaled the audience to stop talking.

When he came to the lecture hall and returned to quiet again, he continued in a clear voice.

"Just yesterday afternoon, Professor Lu revised his research results and left us a better model than 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 really read the paper."

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

Besides, the people who were in this lecture hall yesterday

At this point, Professor Krugman paused for a moment, his eyes stopped on Professor Joseph's face in the front row for a few seconds, then looked at the whole audience, and continued.

"Please don't worry. I will show you the improved Lu Bewley model soon."

"Please listen carefully."

……

With his back to the audience, Professor Krugman wrote on the whiteboard line by line according to the contents of the paper with a marker in his hand, and added detailed descriptive language according to his own understanding of Lu Bewley model and the paper.

Although the formula displayed on the whiteboard at this time is just the tip of the iceberg about the model, many scholars who are good at using mathematical tools sitting here have obviously felt the improved Lu Bewley model, which has a further superior performance compared with the previous model.

This is an academic intuition.

It is also the experience accumulated in macroeconomic research for a long time.

Especially Professor Joseph.

He listened and watched carefully under the stage. At this moment, his face was both shocked and relieved.

Now he finally believed that the man was not joking.

To be able to work out these things in one afternoon, this guy's mathematical attainment has stood at the top of all the scholars he knows

And it's not just about understanding mathematics itself.

This ability to use mathematics as a tool and skillfully apply it to completely different fields to solve the actual problems is really terrible!

I'm afraid even the late math genius John Nash can't do better than him

"Mathematics changes science..." He said to himself and stared at Professor Joseph on the white board. He suddenly smiled and shook his head No wonder he can boast of such a sea mouth. "

"Ha ha, with his ability, he is modest."

It's not just changing science.

It's a redefinition of science!

At least, he redefined his understanding of Mathematical Economics

At the same time, Professor Krugman, standing on the platform, stopped his marker.

After Rereading the paper in his hand and comparing it with the contents on the whiteboard, and confirming that there was no omission or clerical error, he turned to the audience in the lecture hall."Any questions?"

There was silence under the stage. No one spoke or raised his hand.

Looking at the silent stage, Professor Krugman was sure that he had said it clearly, and thought that no one could understand it, so he nodded.

"Then come here..."

Just as he was about to put down the marker, he suddenly raised a hand trembling.

"Wait a minute!"

Just as everyone focused on the past, the young scholar who stood up scratched his cheek in embarrassment and spoke quickly.

"I don't have a question, just about this model How do we name it? Do you have to distinguish it from the original Lu Bewley model? "

It's a question of the point.

There was a lot of discussion in the lecture hall, as if it was discussing the issue.

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

It seems that the model is not named in this paper

Just like the original paper on Lu Bewley model, the name of Lu Bewley model is generally accepted by other scholars when discussing this issue.

It seems that Professor Lu has not much enthusiasm for naming research results in the field of economics.

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

"Or put a Joseph on it? After all, Professor Lu himself admitted that he had been inspired by Professor Joseph's report meeting, which was interrupted in the middle of the sentence.

"I don't deserve it."

In everyone's astonished sight, Professor Joseph, who was sitting in the front row of the lecture hall, suddenly stood up and abruptly interrupted Professor Krugman. After a pause, he continued, "besides, I don't want to be counted as a 'wrong counterexample' by later people in their contribution to this model."

“…… Well, I didn't mean that. " Seeing Professor Joseph's expressionless face, Professor Krugman, who didn't want to offend others, quickly explained, "it's just to distinguish, not as a counterexample."

Ignoring Krugman's explanation, the white haired old man stared at the formula on the whiteboard for a while, and then he was silent for a while.

After that, he spoke.

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

"This is a more open, more operational, and more widely used economic model."

"So I propose to name it in a whole new way That's the L-Z model. "

There was a commotion in the lecture hall.

The scholars, who were sitting in the meeting, nodded their heads and expressed their approval.

Although some people are expressionless and don't agree with the name, their eyes also reflect on what they are thinking.

Sitting under the stage, looking at the back of the former one, Professor Andes nodded approvingly.

"It's Joseph Stiglitz. It seems that yesterday's incident touched him a lot Although I am not qualified to evaluate him, I think after this conference, his achievements in economics can be further improved. "

Sitting next to Professor Andes, Wiesel listened to the big man saying "yesterday's incident". The whole person was confused.

In the end, he could not resist the curiosity in his heart and asked.

"Professor Andes, may I ask What happened yesterday? "

"Were you absent yesterday?" Suddenly something came to mind, and Professor andis said with a sudden look, "Oh, I seem to remember that you really weren't in the lecture hall yesterday."

Wiesel swallowed and asked, "so what happened?"

"It's nothing. It's just a pity that you missed the most wonderful report of this macroeconomic forum."

At this point, looking at the gradually regretful expression on the doctoral student's face, Professor Andes smiled unkindly and added after a pause.

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