The Case for Macroeconomics

Case 1:

Two cars collided, one needed to be overhauled, the other was completely destroyed, and it needed to be repurchased, and the insurance company had to settle the claim. Just when the three parties were very frustrated www.biquge.info an economist said to them, thank you for creating hundreds of thousands of yuan of GDP for the auto repair industry, automobile manufacturing industry, and automobile sales industry.

This is GDP.

Case 2:

A couple of crooks took some pieces of paper with a face value of one dollar written on them and said to a group of fools, we have some magical pieces of paper here, they represent a growing mountain of gold that can continue to rise in value. You see, now that the value of these pieces of paper has increased, we can sell them for 10 yuan each. So the fools flocked to buy those pieces of paper for $10 each. Later, the fools who didn't buy it bought those pieces of paper from the fools in front of them at a price of 20 yuan, 30 yuan, or even more than 100 yuan, and paid the scammers a handling fee. And every fool thinks that there will be bigger fools who will buy those pieces of paper at a higher price. Until one day, the fools found out that the pieces of paper were not worth even a dollar, so the fool who finally bought the pieces of paper at the highest price became the biggest fool.

This is the stock market.

Case 3:

There is a piece of land on which some farmers cultivate and some graze cattle and sheep. A few deceptive words came and said to the peasants grazing cattle and sheep, "We have bought all your cattle and sheep, and you should go to the city to sell beef and mutton." So the deceived peasants had no cattle and sheep, so they gave the land to the swindlers. The scammers built a lot of houses on those lands and sold them and made a lot of money. Seeing that they could make a lot of money, many madmen flocked to it, borrowed a lot of money from the bank, and bought the land of the peasants. Tell the peasants how hard it is to farm, so go to the city too. So the peasants took the money from the sale of their land and went to the city, but found that the money could not even afford to buy an ordinary house, so they had to live in the slums and do hard labor. And those madmen bought land and built a lot of houses, and found that no one had bought them, so they had to sit there and let them collapse, and they couldn't pay off their debts, so they ran away, jumped off buildings, and dragged down the banks. The peasants in the city could not survive, so they ran back one after another, demolished the abandoned houses, planted the land, and grazed the sheep, leaving only a small part to raise chickens and pigs.

That's real estate.

Case 4:

Pigs get rich through hard work, and 5 yuan is stored in the money bank opened by mice. The pig plans to use the 5 yuan to build a small nest, and it will probably cost 2 yuan to buy land and 3 yuan to build a nest. Wang Ba is engaged in engineering, and he wants to make more money on pigs, so he asked the fox who was an investment consultant to find a way, and the fox said: This is easy to do. So find the wolf who is in charge of the territory, and the rats of the money village come together to discuss, and as a result, Wang Ba borrowed 200 yuan from the mouse, sold the wolf's land with 100 yuan, spent 3 yuan to cover the pig's nest, and spent 50 yuan to give the fox consulting fee, the pig has no land, so he had to ask Wang Ba to sell the nest to it, Wang Ba asked for 500 yuan, and the old pig said that only 5 yuan could not afford it, at this time the fox persuaded the pig to borrow money from the mouse, and the mouse promised to lend 500 to the pig, provided that he even paid off 600 yuan with interest, which could be paid off in 10 years, and the property right certificate was mortgaged。 The result is a deal. In the end, the pig spent 600 yuan to buy the pig nest, which was 11 times higher than his original plan, and the pig worked hard for ten years to earn money to pay off the loan. In this transaction, wolves, mice, foxes, and kings all made money. After that, they did the same. More pigs went on loans to buy houses, and at this time, when the merchant's donkey saw an opportunity, he went to the rats for a loan

bought all the houses built by Wang Ba and sold them to the pigs at a higher price. The repayment period of the pigs is getting longer and longer, the food is getting worse and worse, and the piglets do not dare to give birth. As the number of pigs became dwindling, the wolf felt that he had no pork to eat and would have to starve to death, so he began to regulate the rats from borrowing any more money. But Wang Ba has not stopped building houses, and has put all the money he earned and the money he borrowed into production. There are a lot of hoards in the pig's nest in the hands of donkeys, and they can't sell them anymore and are trapped. As a result, the mouse, the king, and the donkey all earned a lot of pig nests. In the end, the money went to the wolf. Now, everyone is waiting for the wolf to take out the money to save their lives. Smart you, who will you save first?

This is the financial crisis.

Case 5:

Two people sell baked cakes, each person sells 20 pieces a day (because the demand for the whole baked cakes is only 40), the price of one yuan is one, and the output value is 40 yuan per day

If the price of the baked cake is 5 yuan, the trading volume is 1040 yuan per day, at this time, A and B will rise the market baked cake to 2 yuan, some people hear that the baked cake is selling for 5 yuan 1, and when they see that the market baked cake is only 2 yuan, they hurry up to buy it

If you can't make the pancakes all at once, you buy forward cakes. On the one hand, A and B increase the number of baked cakes (up to 100 or more per day), on the other hand, sell forward baked cakes, and also start the transaction of issuing bonds of baked cakes, and the purchasers buy them with cash and mortgage loans---

Some people wanted to buy it, and they had neither cash nor collateral, so A and B issued subordinated bonds and bought insurance from insurance agencies, and --- subordinated bonds sowed the seeds of the subprime mortgage crisis

One day, I found that I couldn't eat the baked cakes I bought, and I wanted a place to store them, and I wanted to be moldy, so I quickly sold them, even if the price was lower

And so the financial crisis broke out: the bakery laid off workers (only 40 baked cakes a day) -- unemployment, the burnt cake bonds turned into waste paper -- the subprime mortgage crisis

Mortgages (collateral is worthless) cannot be recovered, lending banks are in a liquidity crisis, insurance companies are facing bankruptcy, etc. --financial crisis

Case 6:

Once upon a time, there was a mountain, and there was a village in the mountain, and this village was called a mountain village. There is a primary school in the mountain village, and the children in the school like to eat marshmallows, and there happens to be a marshmallow master in the mountain village, but the marshmallow master has a rule that he can only make 100 marshmallows a day.

One day, the classmates in the class heard that Xiao Ming got a lot of New Year's money.Xiao Hei said to Xiao Ming: Lend me 100 yuan to buy marshmallows.Xiao Ming: Isn't the marshmallow just 1 yuan?Don't worry, I'll pay you back 150 yuan tomorrow.So Xiao Ming lent Xiao Hei 100 yuan.

The next day, Xiao Hei ran to the marshmallow master early in the morning and slapped 100 yuan on the table: The boss brought me 1 catty. (Note: 1 catty = 100) marshmallow master: Xiao Hei, when did you become so rich.

In the class, the students are discussing: Why are the marshmallows sold so fast today? I didn't buy any of them. Isn't it Xiao Ming..?? Among the countless people's discussions and speculations, only Xiao Bai knew Xiao Hei's plan, and he secretly decided to stop Xiao Hei before he arrived...

School Gates.. When Blackie walks to the classroom... Xiaobai suddenly rushed out of the corner.

Xiao Ming thought oops... The cost of 200 yuan will be 300 yuan tomorrow..

Xiao Hei thought, oops.. I made 50 yuan without much effort.I was afraid of taking the risk of being despised by the public....

Xiaobai thought, oops, is there a way not to sell it yourself... But who wants to take on this role that is spurned by everyone? Xiao Hei must have been ready to be scolded by thousands of people and sprayed by thousands of people, and then go to him to try.

So Xiaobai said to Xiaohei: Now that we have a monopoly on today's marshmallow market, the price can be set however you want, and you can buy it back for 350 yuan... I have to bear a little public opinion, but think that the risk is directly proportional to the profit... Besides, weren't you ready for this result at the beginning? Now that your profits have doubled, you still have to bear so much reputation loss. Why don't you do that? Xiao Hei thought about it, too, so he asked Xiao Ming to borrow money, and said to lend me 300 yuan, and pay you back 350 yuan tomorrow.

Is Xiao Ming still rich?

Suppose that Xiao Ming's New Year's money N=200

Then, at this time, Xiao Ming will say:

You have borrowed all the money, how can you still have money...

Xiaobai borrowed my money, Xiaobai, can only sell marshmallows to his classmates at a high price, but will his classmates buy marshmallows at such a high price?

There are 4 scenarios for this story.

1. Xiao Ming's New Year's money has been borrowed, and his classmates are reluctant to buy high-priced marshmallows.

First Ending:

The next day, Xiao Bai's marshmallow rotted, Xiao Ming's money could not be recovered, only Xiao Hei, the last trader, made a small profit.

But Xiao Ming has no money to lend others to make money.And even if Xiao Ming has money, he no longer trusts others and no longer borrows money casually.Xiao Bai and Xiao Ming's snack career has a crisis..

2. Xiao Ming's New Year's money N=200, but although the classmates despise Xiaobai's approach, they can't resist the temptation of snacks. Xiaobai, who has made a lot of money, decided to continue this tactic tomorrow, but the protagonist changed from Xiaohei to Xiaobai, because of the desire for profit, Xiaobai pushed the price to a new height, but this time the classmates didn't buy his account....

Ending: See First Ending

3. Xiao Ming has a lot of New Year's money, which may be 300, 400 or 1000.

4. Xiao Ming has a lot of New Year's money, which may be 300, or 400 or 1000. (It's a small odds, but it's still counted.)

Ending: See Outcome 1.

Thus, the financial crisis was born.

The economic crisis needs to be added to the section of the marshmallow master.This story needs to be changed.The high price makes the marshmallow master and the cost of the marshmallow rise, and when there is no money to fry the marshmallow, the price drops sharply, and the marshmallow master goes bankrupt.No one makes marshmallows anymore.Who will solve the snack problem.
