Your problem is exactly what Japan has been doing for years, that is, interest rates are close to zero, and GDP growth is slow, or even negative. To solve this problem, the Bank of Japan (BOJ) implemented a monetary policy called quantitative easing (QE) for seven years from 2000 to 2006, and when it ended it in 2006, the Japanese economy remained unremarkable, and it still is. The Japanese have not finally figured out the real reason for this phenomenon.

The United States has faced the same problem since 2007, and in order to avoid repeating the mistakes of Japan, the Federal Reserve launched its famous second quantitative easing policy, or QE2 for short, in November last year. Now the yield on US Treasury bonds has risen from 2-3% to 3-4% instead of lowering as expected, and the market is already feeling inflationary pressure. The question is whether the current inflation in the United States is a sign of economic recovery or the beginning of severe inflation.

The current difficulty for the United States is that in the next 3-5 months, the issuance of national bonds will reach the ceiling of 15 trillion US dollars, and whether the United States will pass a bill to raise the national debt ceiling in time has become the focus of market attention. The Fed's QE2 program is also facing difficulties as it is accused of exacerbating inflation.

Therefore, the lower the interest rate, the more investment is certainly not a universal economic principle. No one has yet given the ultimate answer to this phenomenon, otherwise there would be no QE story. I tried to explain as follows:

1.Due to the development of the U.S. financial industry, too much dollar liquidity has been absorbed, resulting in a relative shortage of liquidity in the production field, and although the various bailout and financial transfusion policies of the U.S. Treasury and the Federal Reserve, as well as the subsequent liquidity injection policy, have increased the total amount of liquidity, the flow of liquidity is still not inclined to the production sector.

2.In both the U.S. and Japan, the increase in industrial investment was hampered by low expectations for economic growth prospects.

3.The excess liquidity in the financial sector has led to an increase in commodities such as oil and iron ore**, which directly increases costs in the production sector and reduces investors' willingness to invest in these sectors.

In short, there is some kind of vicious circle.

Everyone has a sense of speculation and crisis. Take gambling size as an example, when there are 20 small handfuls in a row, do you still think that the next handful will be small? I don't think so!

Since you don't believe that you will continue to be small, then you will choose to be big in order to avoid losses (this is your rationality, and it is also the premise of economics, and the rational person hypothesis).

Back to the question, the interest rate is so low that anyone knows that it is impossible for him to continue to go down (** cannot continue to grow online), when it is basically impossible to obtain higher benefits, who will continue to invest, let alone at the cost of vested interests. Rational people will not, they will only choose to sell** to increase their cash holdings to ensure that their interests do not suffer a greater loss. As a result, there is a lack of investment.

PS: I hope this answer satisfies you. Know that you are anxious to find an answer that satisfies you, but you should also pay attention to your attitude when asking questions.

muy==(1/2)[x^(1/2)]*a*y(-1/2)

mux/muy=8/py

8x+py*y=656

The equation of the demand curve for y is synapsion-specific.

1. y = [b/(a+b)]*m/py] = [b/(a+b)]*656/2]

2. x = [a/(a+b)]*m/px] = [a/(a+b)]*656/8]

Knowing the equation, substituting the cross-elasticity formula and the income elasticity formula leads to the second question.

When the py drops to 1 yuan, while keeping the original consumption level unchanged, it is equivalent to an increase in income (2-1) (y when py=2 yuan)=? Yuan, this is the biggest price he is willing to join. The same is the biggest cost of his membership in the other two cases.

As long as there is a maximum cost greater than 176, join the union. As for which right to choose, it depends on the utility.

For example, the original utility is u=xayb <==, and you can get it by substituting the demand curve equation of x y.

v = a} *b} (note, a denotes the power exponent).

It's best to write this thing on paper... It doesn't seem that complicated ...

After joining this club, the income m = 656 - 176 = 480

So, the functions of x y have changed...

50% buy xx = [a (a+b)]*m px] = [a (a+b)]*480 4].

y = [b/(a+b)]*m/py] = [b/(a+b)]*480/2]

> v = ..

50% Buy YX = [A (A+B)]*M Px] = [A (A+B)]*480 8].

y = [b/(a+b)]*m/py] = [b/(a+b)]*480/1]

> v = ..

75% buy x and y

x = [a/(a+b)]*m/px] = [a/(a+b)]*480/6]

y = [b/(a+b)]*m/py] = [b/(a+b)]*480/

> v = ..

Then the ratio with the original utility is larger, and then the largest utility is selected.

There is a conclusion

Calculation Questions:1The elasticity of cigarette demand is that if a box of cigarettes is now 12 yuan, you want to reduce the amount of cigarettes you smoke by 20%. How much should it be raised?

2.The original ** of a product is 10 yuan kg, the sales volume is 1000kg, the demand elasticity of the product is, if the price of the product is reduced to 8 yuan kg, what is the sales volume at this time? Does the total gain increase or decrease after the price reduction?

3.The demand function of the commodity is: qd=1000-p, and the supply function is: qd=200+p, Q:

1) What is the demand when ** is 500? What is the supply?

2) What is the equilibrium** of the commodity? What is the equilibrium** at this point?

High-quality answers. 1.Due to Demand**Elasticity = Percentage Change in Demand**% Change.

Therefore, **% change = 20%.

12*50%=6 yuan.

**Should be increased by $6.

2.**Percentage drop = (10-8) 10 = 20%.

Percentage increase in sales = 20%*

Sales volume = 1000 * (1 + 48%) = 1480kg

The total income after the price reduction = 1480 * 8 = 11840 yuan, which is higher than the total income of 10,000 yuan before the price reduction.

3.Substituting p=500 into two formulas, we get:

Demand qd=500, supply qs=700

Let qd=qs, find the equilibrium **p=400, equilibrium = 600

1. Net domestic production NDP = GDP - depreciation = 4800 - (800-300) = 4300;

2. Obtained by GDP=c+i+g+nx, nx=gdp-c-i-g=4800-3000-800-960=40;

3. **Income after tax minus transfer payments = **purchase + **budget surplus = 960 + 30 = 990;

4. Personal disposable income = GDP - **tax t = 4800-990 = 3810;

5. From GDP = C + S + T, national savings S = GDP - T - C = 4800-990-3000 = 810, and national savings = private savings + public savings (** savings), so private savings = national savings - public savings = 810-30 = 780.

1. Buy two get one free is a terminal model that can quickly start the market, but it is actually a kind of discrimination, taking advantage of the asymmetry of information between buyers and sellers, which is a means to reduce profits and get more sales for Weishi sellers.

2. It is empirical analysis, empirical analysis is what reality looks like, and normative analysis is what the economy should look like. Empirical tends to explain (why), while norms are (how).

3. When entrepreneurs enter an undetermined field, they will seize the market of the original enterprise under the condition of loss, so that after they obtain a certain amount of monopoly power, they will stop losing money and make their own business, and then Shenshan World will make a profit.

Some companies are losing money at the beginning, such as **.com, Alibaba, etc., which have to lose a few years at the beginning before entering the profit stage.

Hope the answer is helpful to you. As for the more in-depth ones, they need to be studied more.

It's not that there is no truth at all, but from the perspective of making money, he made two fundamental mistakes, first, the risk-return ratio, his annual salary of 120,000 plus the façade to eat and rent let's count it 180,000, the sum of the two is 300,000, in order to keep a good note. However, when Mr. Zhang opened his own restaurant, he lost the above two incomes, which means that at this time, it is not that there is basically no cost as his best friend Mr. Wang said, but that there is 300,000 yuan of original income as a risk that needs to be offset, that is, if he can't earn back 300,000 yuan a year, it will be a loss. As for the risk, Mr. Zhang will offset the increase in income by what percentage, the subject did not write, but even if it is calculated with a return rate of 30%, it should be more than 400,000 yuan per year.

Second, and the key point, the subjective and objective factors are confused, Mr. Zhang's best friend only said that he should open a distinctive restaurant, but Mr. Zhang himself only has some objective advantages in Mr. Wang's mouth for opening a restaurant, and Mr. Zhang does not have any subjective innate conditions for opening a restaurant. Therefore, Mr. Wang's remarks are suspected of putting the cart before the horse.

The Lagrange multiplier method finds conditional extremums.

t is given by finding the partial derivatives for x and y, respectively, and is equal to 0.

2-2x+y=0

2-2y+x=0

The solution is x=y=1, t=3

Then find the second-order derivative verification, and it is easy to know that the second-order partial derivative is -2<0 for both x and y, so the maximum value is obtained.

The less monopoly factors there are, the higher the economic efficiency, so perfect competition monopolistic competition oligopoly is a complete monopoly. Obviously, in order to improve economic efficiency, monopolies will be limited and competition will be promoted. On monopoly and innovation, you can read Schumpeter's writings.

As for why this is the case, I will simply say that monopoly will lead to high monopoly profits, and because of its monopoly position, there are no foreign competitors to share or divide this part of the profits, monopoly enterprises will consolidate their monopoly position through various means, maintain monopoly profits, then there will be rent-seeking behavior, rent-seeking is a non-productive behavior, will lose part of the resources, the higher the degree of monopoly, the more resources are lost, so it is necessary to limit monopoly and promote competition. Theoretically, perfect competition is the most economically efficient without resource loss.

On the other hand, monopoly is not only bad, but also that monopoly gathers a large amount of money, and if this money is used for innovation or other productive activities, then the wealth of the whole society will increase.
