The exam venue was still the same classroom full of hatching eggs before, and Chen Bo made two portions of rice rolls for breakfast, three baskets of xiaolongbao and two large cups of soy milk, which he thought would make his brain cells active.

"Eat and drink enough to go with peace of mind, metabolism is the fate of biology."

Most of the students tacitly chose the previous machine number to stay, and only a few deliberately changed their position, probably because they were superstitious about some feng shui, and they were sure that this number or direction would bring them good luck.

"I have a hunch that this time may not be a team collaboration model." Wang Xu leaned back in the eggshell, twisted his head to Chen Bo's side and shouted.

"Have you figured out what he's going to do? Do you have a specific plan? ”

"Well, I think it's appropriate for this kind of thing to have both a theoretical and a practical part." Wang Xu's tone was calm, and he gave Chen Bo a suggestion before the exam.

"The purpose of the auction is to achieve a win-win situation, so as to maximize the social benefits, assuming that you, as the seller, should fully consider the valuation evaluation of the buyer by different models, so as to design the optimal solution."

"What if I'm the buyer?" Chen Bo asked rhetorically.

Wang Xu added: "It's more of a psychological game, how to get the most profit with the least price, but the content of the exam involves auction theory, so we are more likely to be sellers than buyers." ”

"Can you give me a specific, replicable example." Chen Bo tried to better understand and digest.

"Let me give you an example of the FCC, and I'll give you a historical background."

"Don't, there's no time, just a keyword summary."

Wang Xu's unhurried appearance made Chen Bo very angry, according to his retrospective method, I am afraid that the exam will start as soon as he enters the main topic.

"Simultaneous multiple rounds of additional auctions."

[Please keep quiet, read out the exam discipline below]

The prompt sound of the system came just right, Chen Bo remembered Wang Xu's key words, and kept reciting them silently in his heart.

Wang Xu said that the past auctions did not establish a relationship between individual buyers, and the traditional concept is that buyers bid separately for the auction items and finally reach the psychological expected price.

But in practice, in public auctions, many buyers will constantly revise their psychological expectations because of other people's bids, and when they are dominated by emotion, this practice is often beyond the scope of tolerance, leading to the curse of the winner.

The most typical example is natural resources such as oil fields, which are difficult to accurately estimate the production and subsequent benefits during the initial auction.

Due to the influence of multiple factors, it may be that the technology will usher in an explosion and reduce the cost of collection, or it may be judged that oil prices will rise sharply in the future, and it is easy to fall into blind optimism and valuation misjudgment when seeing peers competing to bid.

When bidding at the second price, the only best choice for each buyer is to vote for the price in their minds, not higher or lower, Wang Xu listed a few formulas for Chen Bo at first, but the fat man looked constipated, so he had to re-translate it in human words.

"For example, the value of a thing to you is 100 yuan, should you pay 99 yuan, the answer is no, here is the situation, if the highest price is 101 yuan, there is no difference between you 99 yuan and 100 yuan, they are all unsuccessful, and assuming you are the highest price, the second highest price is 98 yuan, then you pay 100 yuan and 99 yuan is no different, because you can get it."

"But if the next highest price is 99.5 yuan, there is a difference between your 100 yuan and 99 yuan, 100 yuan will let you pay at the second highest price of 99.5 yuan, and you will get a profit of 0.5 yuan, and the bid of 99 yuan will be lost."

"On the contrary, the value of a thing to you is 100 yuan, and you should not pay 101 yuan, if the highest price is 102 yuan, there is no difference, you are the highest price at the same time the second highest price is 99 yuan, there is no difference, but if the second highest price is 100.5 yuan, you will suffer a loss of 0.5 yuan if you take 101 auctions."

"It's over, what's the full name of the auction he just said?" Chen Bo patronized and recalled the content of yesterday's chat, but forgot the keyword he had just given.

"Ma Dongmei-style memory, I'm just a college student, so it's not easy to use, I'm afraid that there are really brain-eating worms."

The situation is as Wang Xu said, this time Chen Bo is in an old office, with a huge world map hanging on the wall on the left, and a dartboard for practice on the right.

On the table were a bunch of useless meeting minutes and lab notes, as well as an invitation letter from the FCC.

“FCC？ The FCC, oh shit, should have let this guy finish the historical context. Chen Bo frowned and opened the envelope, which was covered with the familiar dear beginning.

"Dear Mr. Paul, we sincerely invite you to participate in the design of the 3G spectrum bidding scheme, thank you for taking the time to reply, if you can come as scheduled, we are very honored and look forward to your joining."

Chen Bo finished chattering, enveloped the envelope back, walked to the door, poked his head out of the corridor, and asked tentatively.

"Is anyone there?"

"Professor, do you need any help?" A young blonde guy approached him with a bag of papers.

"Who are you? What is your name. Chen Bo asked.

Parker looked puzzled and explained with a smile, "Professor, you don't know me anymore?" I'm Parker, my assistant who just arrived last week. ”

"Parker, do you know someone named Wang Xu?" Chen Bo was a little flustered, if he really fought alone, he would have no bottom in his heart after all.

Parker thought for a moment and explained, "Mr. Wang is already waiting for you at the office of Federal Communications, and the invitation has already been received." ”

"Oh, I got it, then I can go."

Chen Bo was overjoyed, he picked up the black satchel on the seat, Parker volunteered to be the driver, Chen Bo sat in the passenger seat, the seat of the old-fashioned Beetle was a little stiff, and he jumped up and down on the gravel road.

After arriving at the office of the Federal Communications Commission, Chen Bo met Mr. Wang as Parker said, but the other party seemed to look at him as a stranger.

Wilson, the executive in charge of this matter, said: "Professor Paul, it is great that you can join the bidding design, and I will introduce you to Professor Wang Xu, an excellent mathematician, and the expert we have invited. ”

"Hello, Professor Paul." The other party enthusiastically stretched out his hand to show goodwill.

"Hello." As an authentic Chinese level 10 player, Chen Bo can still hear the difference between Wang Xu and Wang Xu, but unfortunately Parker can't tell the difference, and he is happy in vain.

"Time is pressing, please move to the conference room, and I will give you a brief briefing." Wilson took the two of them from the reception room to the meeting place, but Parker did not follow, presumably returning to the institute.

On the way, Wang Xu touted: "Professor Paul, I have also studied your theory a little, to be honest, I am very surprised, I didn't expect that the simple theory can be so perfectly in line with reality, and I look forward to this cooperation." ”

"Me too, wishing it all the best." Chen Bo didn't understand what the old man's research results were, so he had to be embarrassed and perfunctory.
