Zhou Libo's joke

There are two very smart and talented young people in economics. They often argue about some profound economic theories. One day after dinner, I went for a walk, and two excellent young people argued again for the proof of a mathematical model. When they were having a tense game, they suddenly found a pile of shit on the grass in front of them. A said to B, I am willing to pay 50 million yuan if you can eat. The temptation of 50 million is not small. Do you want to eat or not? B took out a pen and paper, made an accurate mathematical calculation, and soon got the optimal solution in economics: eat! So A lost 50 million yuan. Of course, it is not easy to add meals to B.

As they walked on, they suddenly found a pile of shit. At this time, B began to feel severe nausea, and A felt a little distressed and just spent 50 million yuan. So b said, you eat, I'll give you 50 million. Therefore, different calculation methods have the same calculation result >: ——& gt；; Eat! A contentedly recovered 50 million yuan, while B seemed to find a little psychological balance.

But suddenly, the geniuses wailed at the same time: we didn't get anything for a long time, but we ate two piles of shit for nothing! They couldn't figure it out, so they had to ask their tutor, a famous economist, to explain.

After listening to the stories of two tall men, I didn't expect the leading men to cry. I finally waited for my mood to stabilize a little, only to see the master trembling and holding up a finger, and said with great excitement: > "> 1 100 million! 1 billion! Dear students, I thank you on behalf of the motherland and the people. You just ate two piles of shit and contributed 1 100 million to the national GDP! "
