Micro economy and virtual currency

1. I don't know who knows how BTC coin makes money. Now there are many platforms that use blockchain to cheat money. Each platform has different operations. Some platforms make money when you buy a bitcoin and sell it when it goes up, and lose when it goes down. There is also a platform for you to buy a bitcoin and transfer it to your wallet. No matter whether the coin goes up or down, there will be income every day. If the coin goes up, there will be more income and the coin goes down, there will be less income. Anyway, there will be income every month.

2. digital currency is the proct of currency development to a certain stage. The issuance of digital currency is mainly to make transportation more convenient and also concive to the supervision of the economy.

3. 1. Elasticity is equal to the slope multiplied by Y / X. the slope of a straight line is equal at every point, but the Y / X of a straight line is obviously different at every point, unless the line is vertical or horizontal. It's right to be uncertain about the price of a proct. It depends on the amount of translation. If the demand increases more, the price will rise, and if the supply decreases more, the price will fall

4. It's called exchange or transaction

e-money is e-money; digital money e-cash e-currency electronic cash electronic money electronic wallet A means of payment that can be made on the Internet or by other means of electronic communication. This kind of currency has no physical form and is the holder's financial credit. With the rapid development of the Internet, this kind of payment method is becoming more and more popular

at present, bitcoin, Fuyuan coin, Laite coin and doggy coin are popular in China. It can be exchanged at home, which is also legal.

The answer is:

(1) the procer's supply curve moves downward to the right, and the vertical distance is equal to the unit cash subsidy
(2) the procer's supply curve moves upward to the left, and the vertical distance is equal to the unit sales tax
(3) the implementation of price floor or price ceiling is the government's intervention in the market mechanism, which may result in the failure to reach the equilibrium point of commodities. In the first two cases, the equilibrium point will change, but it still occurs at the intersection of the supply and demand curve. This means that the government is acting through the market, rather than interfering in the operation of the market

6. First of all, remember that this is an isoline, not a proction function curve. Each point on the line represents the combination of labor and capital to be invested under the same output
on the left side of MPL = 0, when the total output is the same, more labor can rece capital input, that is, labor has a positive contribution to output, that is, the marginal output of labor is positive; On the right side of MPL = 0, when the total output is the same, more labor and more capital are needed to maintain the original output. It can be seen that more labor has a negative contribution to the output, that is, the marginal output of labor is negative.

7. Note: AC=3000/Q+40
TC=AC×Q
TC=3000+40Q
MC=TC '= 40
P=200-Q/5
TR=200Q-Q ² / 5
MR=200-2Q/5
orderMR=MC, which is:
200-2Q/5=40
1000-2Q=200
Q=400
P=160

This is in the intermediate microeconomics, in order to meet the requirements of mathematical proof, we use the anti demand function to dece the consumer surplus

In primary microeconomics, the demand function can be used to dece

1. Derivation of demand function

consumer surplus refers to the difference between the highest price consumers are willing to pay for a certain number of goods and the actual market price of these goods. The demand curve not only shows the relationship between price and demand of goods, but also can be understood as the highest price consumers are willing to pay when purchasing a specific quantity. But for consumers, the market price is given, so there is a difference between their willingness to pay and the actual payment, which constitutes a "psychological surplus". The difference between the amount that consumers are willing to pay and the amount that they actually have to pay in order to get a certain amount of a certain commodity is called consumer surplus

the total consumer surplus can be expressed by the area of the triangle formed by the demand curve, the price line and the price axis
