When Lu Zhou arrived at Lecture Hall No. 1, the report meeting had already begun.
"As we all know, the Bewley model has gradually become a mainstream method in macroeconomic research because it has overcome the inherent shortcomings of the stochastic dynamic general equilibrium framework. The Lu-Bewley model has been improved on this basis, such as using the 'endogenous grid method' etc. Many mathematical tools have replaced the tedious operations of solving each step in the optimization process using the Lagrange multiplier method... "
"In my opinion, these shortcomings are fatal!"
Listening to these people's whispered exchanges, Lu Zhou's eyebrows slightly raised.
And the few people sitting on the floor under the podium basically wore thick glasses and looked very, very young. This kind of people come to the lecture meeting with questions or purposes. Regardless of whether there are seats in the lecture hall, they basically sit there.
As this voice came from the back row of the lecture hall, the huge lecture hall instantly became lively...
Thinking of this, a hint of disappointment appeared on Joseph's face, as well as a hint of the loneliness of a master.
This reminded Lu Zhou of his own lectures. Whenever he gave a lecture, the audience would basically have the same look and state.
However, even if he found out, Lu Zhou probably wouldn't take it too seriously.
Standing in front of the PPT screen, an old man with white hair and beard pushed up his glasses on the bridge of his nose and was speaking in a leisurely voice something that Lu Zhou couldn't understand at all.
Professor Joseph, who was standing on the stage and speaking slowly, suddenly frowned when he saw a spot of light from the back row of the podium.
Professor Andis also nodded, agreeing with what his old friend Professor Krugman said.
[f(x,y,z)=ag3,1+bg3,2+cg3,3…where x,y,z≥0…]
However, although he could not understand it at all, the scholars in the audience listened very carefully, even intoxicated.
However, although he could not understand it at all, the scholars in the audience listened very carefully, even intoxicated.
He is a master.
Did Joseph say these words specifically to him
Many people still agree with this joke made by the old gentleman.
"I have some questions."
This reminded Lu Zhou of his own lectures. Whenever he gave a lecture, the audience would basically have the same look and state.
"It's hard to say," Professor Krugman shook his head, "I don't think there are any flaws... But this old guy, Joseph, has a better understanding of mathematical models of economics than I do. Maybe he has discovered something that I haven't. There may be problems discovered.”
At this moment, Lu Zhou didn't notice that he was disliked by a certain economics guru because of this inconspicuous action.
"We all know that a quite novel mathematical model has recently been born in the field of economics. Its creator is the well-known Fields Medal winner Professor Lu Zhou. By improving it on the basis of the classic Bewley model, it saves a lot of tedious work. calculation, and make the model calculation results more accurate... "
Although I don’t really understand the debates in the economics community, I always feel that things are gradually becoming interesting...
"I don't deny that this mathematical model is beautiful, everyone, I don't deny it."
After a pause, Professor Joseph continued.
He is a master.
Read the paper from beginning to end, whether it is the mathematical model part or the theoretical part.
As this voice came from the back row of the lecture hall, the huge lecture hall instantly became lively...
Make a judgment.
[f(x,y,z)=ag3,1+bg3,2+cg3,3…where x,y,z≥0…]
He has basically forgotten the theory of the Lu-Bewley model. Although this thing seemed to be somewhat important to the economics world, to him, it was just a random gadget, so he didn't take it to heart at all.
"Yes, yes, Professor Krugman must be here! Professor Joseph's words may be meant for him... in response to the paper he wrote some time ago!"
As his explanation continued, line after line of calculations were printed on the whiteboard.
The moment the words fell, whispers suddenly spread in the lecture hall.
With this thought in his mind, Lu Zhou didn't wait any longer at the door and quickly found an empty seat in the last row and sat down.
"However, this also makes the Bewley model lose its original rigor."
"However, this also makes the Bewley model lose its original rigor."
The guy couldn't even keep up with his explanation.
But if he knew the reason, he would definitely laugh or cry at the old gentleman's eyesight.
"It's hard to say," Professor Krugman shook his head, "I don't think there are any flaws... But this old guy, Joseph, has a better understanding of mathematical models of economics than I do. Maybe he has discovered something that I haven't. There may be problems discovered.”
In fact, the statement of the doctor named Weisl was a bit exaggerated. Although there were indeed many people in the lecture hall, they were not so crowded that they could not find a seat and had to sit in the corridor.
"As we all know, the Bewley model has gradually become a mainstream method in macroeconomic research because it has overcome the inherent shortcomings of the stochastic dynamic general equilibrium framework. The Lu-Bewley model has been improved on this basis, such as using the 'endogenous grid method' etc. Many mathematical tools have replaced the tedious operations of solving each step in the optimization process using the Lagrange multiplier method... "
Somewhat unable to keep her composure, Xiaotong finally couldn't help but asked in a low voice: "Professor, is the Lu-Bewley model... really defective?"
Professor Andis also nodded, agreeing with what his old friend Professor Krugman said.
Professor Joseph on the stage continued to talk, and at the same time used a marker in his hand to write down the key points of the explanation on the whiteboard from time to time.

However, Joseph just frowned, and then ignored the person who made him unhappy.
Although it is not uncommon to play with mobile phones during lectures, he has always been disgusted with this behavior, which makes him feel that his research results are not as attractive as mobile phones.
He has basically forgotten the theory of the Lu-Bewley model. Although this thing seemed to be somewhat important to the economics world, to him, it was just a random gadget, so he didn't take it to heart at all.

I originally thought this guy could tell me something, but I didn't expect that he couldn't even ask a question.
"Although this lecture is based on the Lu-Bewley model, what I am going to say next may disappoint many people." He took a deep look at Professor Krugman, who was sitting in the front seat. After staying for a few seconds with this fellow Nobel Prize winner who strongly advocated the Lu-Bewley model, Joseph continued, "I will focus the report on revealing the shortcomings of the Lu-Bewley model."
After finding his seat, Lu Zhou sat down and stretched his neck to look around. Then he took out his mobile phone. While looking for a review of the paper he and Xiaotong had collaborated on before, he devoted some of his energy to listening to a few words from Professor Joseph. explain.
Friendly laughter erupted in the venue.

The light emitted by the mobile phone screen is actually not obvious. It can even be said that if you don't stare there specifically, you may not notice it.

There is no one who can fight!
Firstly, he is not a scholar in the field of economics, and secondly, at his current level, there are not only a thousand but also eight hundred people who care about him, not less than one or two...
Professor Krugman looked solemn.
Indeed, today's new economists are becoming more and more dependent on computers and mathematical tools, and even Nobel economics is increasingly becoming the "Nobel Prize in Mathematics".
Make a judgment.
But now he took out the paper and reviewed it again. He quickly picked up the core content of the paper-that is, the mathematical model part.
What's more, speaking with conscience, he is not playing with his mobile phone, but reviewing the previous article!
Just when he leaned his head back on the chair, he happened to hear two young scholars sitting next to him who looked like they were studying for a Ph.D., whispering to each other.
However, Joseph just frowned, and then ignored the person who made him unhappy.
This reminded Lu Zhou of his own lectures. Whenever he gave a lecture, the audience would basically have the same look and state.
I still remember when he was a professor at Princeton. Not only did he multitask, he could even multitask and ask questions while listening.
I originally thought this guy could tell me something, but I didn't expect that he couldn't even ask a question.
For ordinary people, this kind of dual-tasking method is most likely to displease both ends and not take care of either.
"It's hard to say," Professor Krugman shook his head, "I don't think there are any flaws... But this old guy, Joseph, has a better understanding of mathematical models of economics than I do. Maybe he has discovered something that I haven't. There may be problems discovered.”
"Didn't Professor Krugman discuss the Lu-Bewley model in his new paper? His attitude seems to be exactly the opposite of Professor Joseph's?"
Friendly laughter erupted in the venue.
Let him go.
Sitting in the lecture hall, Professor Krugman's expression was a little stiff.
Stopping the marker in his hand, Professor Joseph looked back at the lecture hall and continued.
"In my opinion, these shortcomings are fatal!"
"My story is over. If you have any questions, you can ask them."
But for Lu Zhou, who often did this to save time, he was almost used to it.
Although it is not uncommon to play with mobile phones during lectures, he has always been disgusted with this behavior, which makes him feel that his research results are not as attractive as mobile phones.
However, in the lecture hall where everyone was staring at him meticulously, expecting him to continue speaking, one person kept his head buried in the screen of his mobile phone and kept making small movements, no matter how far away he was, no matter how far away he was. Sitting in the last row, it was so conspicuous from his perspective.

Professor Krugman is also in the lecture hall
"Needless to say! Professor Krugman and Professor Nash have always had a good relationship! He is a supporter of mathematical economics theory. His most classic view is that he believes that beautiful economic models must have beauty in the mathematical sense … But he seems to have average math abilities.”
Professor Joseph, who was standing on the stage and speaking slowly, suddenly frowned when he saw a spot of light from the back row of the podium.
With this thought in his mind, Lu Zhou didn't wait any longer at the door and quickly found an empty seat in the last row and sat down.
Let him go.
"The significance of economics is to study the laws of human economic activities, that is, the laws of creation, transformation and realization of value, not a numbers game. We are economists, not financial accountants."

"I don't deny that this mathematical model is beautiful, everyone, I don't deny it."
However, Joseph just frowned, and then ignored the person who made him unhappy.
Professor Krugman looked solemn.
Although he didn't intend to compare with this guy, he was just very dissatisfied with this guy's argument of advocating the Lu-Bewley model.
"Although this lecture is based on the Lu-Bewley model, what I am going to say next may disappoint many people." He took a deep look at Professor Krugman, who was sitting in the front seat. After staying for a few seconds with this fellow Nobel Prize winner who strongly advocated the Lu-Bewley model, Joseph continued, "I will focus the report on revealing the shortcomings of the Lu-Bewley model."
If this was in his class, he would definitely ask the person playing with his mobile phone to go out, but this is an academic lecture, and he cannot delay other scholars' time because of such a trivial matter, and there is no such thing as a threat as a credit. …
[f(x,y,z)=ag3,1+bg3,2+cg3,3…where x,y,z≥0…]
I originally thought this guy could tell me something, but I didn't expect that he couldn't even ask a question.
When he said this, Professor Joseph glanced in the direction of Professor Krugman and saw that he was looking at the blackboard with a confused look on his face. He couldn't help but twitch the corner of his mouth slightly.
"I don't deny that this mathematical model is beautiful, everyone, I don't deny it."

"As we all know, the Bewley model has gradually become a mainstream method in macroeconomic research because it has overcome the inherent shortcomings of the stochastic dynamic general equilibrium framework. The Lu-Bewley model has been improved on this basis, such as using the 'endogenous grid method' etc. Many mathematical tools have replaced the tedious operations of solving each step in the optimization process using the Lagrange multiplier method... "
Professor Joseph's words undoubtedly slapped him in the face.
Let him go.
If this was in his class, he would definitely ask the person playing with his mobile phone to go out, but this is an academic lecture, and he cannot delay other scholars' time because of such a trivial matter, and there is no such thing as a threat as a credit. …
Professor Andis also nodded, agreeing with what his old friend Professor Krugman said.
Indeed, today's new economists are becoming more and more dependent on computers and mathematical tools, and even Nobel economics is increasingly becoming the "Nobel Prize in Mathematics".
Firstly, he is not a scholar in the field of economics, and secondly, at his current level, there are not only a thousand but also eight hundred people who care about him, not less than one or two...
He has basically forgotten the theory of the Lu-Bewley model. Although this thing seemed to be somewhat important to the economics world, to him, it was just a random gadget, so he didn't take it to heart at all.
Although it is not uncommon to play with mobile phones during lectures, he has always been disgusted with this behavior, which makes him feel that his research results are not as attractive as mobile phones.
Read the paper from beginning to end, whether it is the mathematical model part or the theoretical part.
The venue fell silent.
Just when he leaned his head back on the chair, he happened to hear two young scholars sitting next to him who looked like they were studying for a Ph.D., whispering to each other.
But if he knew the reason, he would definitely laugh or cry at the old gentleman's eyesight.
And the few people sitting on the floor under the podium basically wore thick glasses and looked very, very young. This kind of people come to the lecture meeting with questions or purposes. Regardless of whether there are seats in the lecture hall, they basically sit there.
Many people still agree with this joke made by the old gentleman.
"Didn't Professor Krugman discuss the Lu-Bewley model in his new paper? His attitude seems to be exactly the opposite of Professor Joseph's?"
He is a mathematician himself and is a complete layman in the field of economics. Even if there are indeed fatal flaws, it is understandable.
Professor Joseph, who was standing on the stage and speaking slowly, suddenly frowned when he saw a spot of light from the back row of the podium.
"Didn't Professor Krugman discuss the Lu-Bewley model in his new paper? His attitude seems to be exactly the opposite of Professor Joseph's?"
The moment the words fell, whispers suddenly spread in the lecture hall.
But for Lu Zhou, who often did this to save time, he was almost used to it.
As his explanation continued, line after line of calculations were printed on the whiteboard.
"Needless to say! Professor Krugman and Professor Nash have always had a good relationship! He is a supporter of mathematical economics theory. His most classic view is that he believes that beautiful economic models must have beauty in the mathematical sense … But he seems to have average math abilities.”
As this voice came from the back row of the lecture hall, the huge lecture hall instantly became lively...
"Although this lecture is based on the Lu-Bewley model, what I am going to say next may disappoint many people." He took a deep look at Professor Krugman, who was sitting in the front seat. After staying for a few seconds with this fellow Nobel Prize winner who strongly advocated the Lu-Bewley model, Joseph continued, "I will focus the report on revealing the shortcomings of the Lu-Bewley model."
What's more, Professor Joseph only criticized the economic value of his Lu-Bewley model, and did not say that there were problems with his mathematical theory.
"This report seems to be interesting."
Friendly laughter erupted in the venue.
I still remember when he was a professor at Princeton. Not only did he multitask, he could even multitask and ask questions while listening.
"Yes, yes, Professor Krugman must be here! Professor Joseph's words may be meant for him... in response to the paper he wrote some time ago!"
When he said this, Professor Joseph glanced in the direction of Professor Krugman and saw that he was looking at the blackboard with a confused look on his face. He couldn't help but twitch the corner of his mouth slightly.
In response to Professor Joseph's criticism, Lu Zhou almost didn't vomit blood at first, but after hearing what he said later, his expression returned to normal.
Professor Krugman looked solemn.
"This report seems to be interesting."

Stopping the marker in his hand, Professor Joseph looked back at the lecture hall and continued.
The guy couldn't even keep up with his explanation.
"It's a pity that compared to Professor Joseph, Professor Krugman's status is still a little lower! Even Samuelson, the author of "Economics", said he felt ashamed!"
"It's hard to say," Professor Krugman shook his head, "I don't think there are any flaws... But this old guy, Joseph, has a better understanding of mathematical models of economics than I do. Maybe he has discovered something that I haven't. There may be problems discovered.”
When he said this, Professor Joseph glanced in the direction of Professor Krugman and saw that he was looking at the blackboard with a confused look on his face. He couldn't help but twitch the corner of his mouth slightly.
After glancing around the scene in the lecture hall, Professor Joseph continued in a serious tone, "Although I am a supporter of the new economic and trade theory, I often use mathematics as an auxiliary tool to assist my quantitative research on economic theories. But I must emphasize again that mathematics in economics is just an auxiliary tool, as if we are a 'macroeconomics forum' rather than an 'accounting and finance forum'."
However, although he could not understand it at all, the scholars in the audience listened very carefully, even intoxicated.
"Needless to say! Professor Krugman and Professor Nash have always had a good relationship! He is a supporter of mathematical economics theory. His most classic view is that he believes that beautiful economic models must have beauty in the mathematical sense … But he seems to have average math abilities.”
Listening to these people's whispered exchanges, Lu Zhou's eyebrows slightly raised.
For ordinary people, this kind of dual-tasking method is most likely to displease both ends and not take care of either.
Let him go.
Professor Krugman is also in the lecture hall
Although he didn't intend to compare with this guy, he was just very dissatisfied with this guy's argument of advocating the Lu-Bewley model.
The moment the words fell, whispers suddenly spread in the lecture hall.
In fact, the statement of the doctor named Weisl was a bit exaggerated. Although there were indeed many people in the lecture hall, they were not so crowded that they could not find a seat and had to sit in the corridor.
However, even if he found out, Lu Zhou probably wouldn't take it too seriously.
Professor Joseph's words undoubtedly slapped him in the face.
Did Joseph say these words specifically to him
"Yes, yes, Professor Krugman must be here! Professor Joseph's words may be meant for him... in response to the paper he wrote some time ago!"
After reading it, Lu Zhou put his phone away and was planning to listen with interest to hear how Professor Joseph evaluated his mathematical model. Unexpectedly, he had just focused his attention on the old man on the stage. The gentleman's next words almost made him vomit blood.
Although I don’t really understand the debates in the economics community, I always feel that things are gradually becoming interesting...
He has basically forgotten the theory of the Lu-Bewley model. Although this thing seemed to be somewhat important to the economics world, to him, it was just a random gadget, so he didn't take it to heart at all.
But for Lu Zhou, who often did this to save time, he was almost used to it.
"My story is over. If you have any questions, you can ask them."
"It's a pity that compared to Professor Joseph, Professor Krugman's status is still a little lower! Even Samuelson, the author of "Economics", said he felt ashamed!"
"It's hard to say," Professor Krugman shook his head, "I don't think there are any flaws... But this old guy, Joseph, has a better understanding of mathematical models of economics than I do. Maybe he has discovered something that I haven't. There may be problems discovered.”

Sitting in the lecture hall, Professor Krugman's expression was a little stiff.

Just when he leaned his head back on the chair, he happened to hear two young scholars sitting next to him who looked like they were studying for a Ph.D., whispering to each other.
"My story is over. If you have any questions, you can ask them."
Let him go.
"I have some questions."
Firstly, he is not a scholar in the field of economics, and secondly, at his current level, there are not only a thousand but also eight hundred people who care about him, not less than one or two...
Listening to these people's whispered exchanges, Lu Zhou's eyebrows slightly raised.

He has basically forgotten the theory of the Lu-Bewley model. Although this thing seemed to be somewhat important to the economics world, to him, it was just a random gadget, so he didn't take it to heart at all.
The light emitted by the mobile phone screen is actually not obvious. It can even be said that if you don't stare there specifically, you may not notice it.
Somewhat unable to keep her composure, Xiaotong finally couldn't help but asked in a low voice: "Professor, is the Lu-Bewley model... really defective?"
Firstly, he is not a scholar in the field of economics, and secondly, at his current level, there are not only a thousand but also eight hundred people who care about him, not less than one or two...
"The significance of economics is to study the laws of human economic activities, that is, the laws of creation, transformation and realization of value, not a numbers game. We are economists, not financial accountants."
"I don't deny that this mathematical model is beautiful, everyone, I don't deny it."
"As we all know, the Bewley model has gradually become a mainstream method in macroeconomic research because it has overcome the inherent shortcomings of the stochastic dynamic general equilibrium framework. The Lu-Bewley model has been improved on this basis, such as using the 'endogenous grid method' etc. Many mathematical tools have replaced the tedious operations of solving each step in the optimization process using the Lagrange multiplier method...

The guy couldn't even keep up with his explanation.
"If you introduce the KPR utility function to equation 3 for testing, you can clearly find problems in the model."
Just when he was stacking the papers on the desk and preparing to wait a while until no one raised their hands so that he wouldn't waste time, a hand that he didn't expect was raised from the back row.
Let him go.
Although it is not uncommon to play with mobile phones during lectures, he has always been disgusted with this behavior, which makes him feel that his research results are not as attractive as mobile phones.
Professor Andis also nodded, agreeing with what his old friend Professor Krugman said.
Professor Joseph on the stage continued to talk, and at the same time used a marker in his hand to write down the key points of the explanation on the whiteboard from time to time.
He is a master.
"Have to listen again, maybe it's not that bad."
But now he took out the paper and reviewed it again. He quickly picked up the core content of the paper-that is, the mathematical model part.
What's more, Professor Joseph only criticized the economic value of his Lu-Bewley model, and did not say that there were problems with his mathematical theory.
If this was in his class, he would definitely ask the person playing with his mobile phone to go out, but this is an academic lecture, and he cannot delay other scholars' time because of such a trivial matter, and there is no such thing as a threat as a credit. …
Just when he leaned his head back on the chair, he happened to hear two young scholars sitting next to him who looked like they were studying for a Ph.D., whispering to each other.
"As I just said, the Lu-Bewley model has fatal flaws in theory, and at least it needs to be significantly modified."
Professor Krugman looked solemn.
"It's a pity that compared to Professor Joseph, Professor Krugman's status is still a little lower! Even Samuelson, the author of "Economics", said he felt ashamed!"

"Yeah, I have to listen again."
I originally thought this guy could tell me something, but I didn't expect that he couldn't even ask a question.
There is no one who can fight!
Sitting in the lecture hall, Professor Krugman's expression was a little stiff.

By improving it on the basis of the classic Bewley model, it saves a lot of tedious work. calculation, and make the model calculation results more accurate... "
It's like you can hear a pin drop.
[…]
Professor Krugman looked solemn.
"However, this also makes the Bewley model lose its original rigor."
In response to Professor Joseph's criticism, Lu Zhou almost didn't vomit blood at first, but after hearing what he said later, his expression returned to normal.
Stopping the marker in his hand, Professor Joseph looked back at the lecture hall and continued.
[f(x,y,z)=ag3,1+bg3,2+cg3,3…where x,y,z≥0…]
"Have to listen again, maybe it's not that bad."
Did Joseph say these words specifically to him
The venue fell silent.
I originally thought this guy could tell me something, but I didn't expect that he couldn't even ask a question.
After finding his seat, Lu Zhou sat down and stretched his neck to look around. Then he took out his mobile phone. While looking for a review of the paper he and Xiaotong had collaborated on before, he devoted some of his energy to listening to a few words from Professor Joseph. explain.
"Yes, yes, Professor Krugman must be here! Professor Joseph's words may be meant for him... in response to the paper he wrote some time ago!"
[…]
Many people still agree with this joke made by the old gentleman.
However, Joseph just frowned, and then ignored the person who made him unhappy.
As his explanation continued, line after line of calculations were printed on the whiteboard.
"Yes, yes, Professor Krugman must be here! Professor Joseph's words may be meant for him... in response to the paper he wrote some time ago!"
What's more, speaking with conscience, he is not playing with his mobile phone, but reviewing the previous article!
He is a master.
"I don't deny that this mathematical model is beautiful, everyone, I don't deny it."
In fact, the statement of the doctor named Weisl was a bit exaggerated. Although there were indeed many people in the lecture hall, they were not so crowded that they could not find a seat and had to sit in the corridor.

Standing in front of the PPT screen, an old man with white hair and beard pushed up his glasses on the bridge of his nose and was speaking in a leisurely voice something that Lu Zhou couldn't understand at all.
