the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

National income is one of the basic theories in macroeconomics. National income (Ni) = total expenditure (AE). In terms of use value, national income is composed of means of proction and means of consumption that reflect the new value creation
The simple theory of national income determination in macroeconomics only includes proct market, that is, national income (Ni) = total expenditure (AE)it should be divided into two departments, three departments and four departments. The more departments there are, the more complex they are. Two departments are C + S = C + I; three departments are C + S + T = C + I + G; The four sectors are C + S + T + k = C + I + G + (x-m). C is consumption, s is savings, I is investment, t is government net income, G is government purchase, K is domestic residents' transfer payment to foreigners, and (x-m) is net export
extended data:
the basic model describing the equal relationship between national income and aggregate demand in macroeconomics. Where Ni is national income and AE is total demand. This model discusses the relationship between national income and aggregate demand. In the two sector (consumer goods sector and investment goods sector) model, net tax NT, government purchase expenditure GP and net export NX are equal to zero
where C is consumption and MPC is marginal propensity to consume., It means that I investment is an exogenous variable, because Ni = AE, under the condition of given marginal propensity to consume, every quantity of I will lead to an equilibrium national income Ni. In essence, what is described here is the multiplier effect in the general theory
a fully competitive market refers to a market structure in which competition is free from any hindrance and interference
the difference between many suppliers in the proction and sales of similar procts in a monopolistic competitive market is that the competitive factor in the market is the monopoly factor of the existing market structure
oligopoly refers to the market structure in which a few manufacturers control the proction and sales of the whole market
the market structure of a monopoly market as a whole instry means that there is only one procer< The characteristics of perfect competition in the four level market are as follows:
quantity of procts, low price, high efficiency
monopoly competition: a little higher price, high efficiency
oligopoly: a small amount of high price, low efficiency
monopoly: the most expensive, The most effective
relationship between marginal propensity to consume and average propensity to consume
the least number: average propensity to consume refers to the percentage of consumption in income, APC: APC = b = C / y
for example, a social income of 200 billion yuan, consumption expenditure of 150 billion yuan, average propensity to consume is 0.75 (1.5 / 2)
marginal propensity to consume is the proportion of increased consumption to increased income, MPC, that is, MPC = △ C / △ y
the marginal propensity to consume is 0.5 (0.5 / 1) when income increases by 300 billion yuan (1 trillion yuan) and consumption increases to 200 billion yuan (0500 billion yuan)< The basic rules of APC and MPC are as follows:
(1) the average propensity to consume APC and the marginal propensity to consume MPC decrease. As income increases, consumption also increases, but the growth rate of consumption is lower than that of income (APC decreases), and the growth rate of consumption is smaller and smaller (MPC decreases). APC and MPC, from the perspective of Keynesianism, explain one of the three laws of Keynesian effective demand shortage
(2) the slope of the consumption curve C = C0 + of MPC should be equal, but in the long run, the slope of the consumption curve will be smaller and smaller< br />
3APC> MPC, as you can see, compares APC and MPC numbers in table 10-1. This is because even if the income is zero, it will be the consumer's basic C0. MPC should be less than 1, but greater than zero< (4) the relationship between consumption and income can be divided into three situations:
C & gt; Y,APC> < br />
C APC> < br />

What is the average nominal interest rate in three years (2) when the nominal interest rate is 10% and the real interest rate is only 5%, what is the expected inflation rate 6 points for this question)
6. Short answer question (6 points for each question, 18 points in total)
1. From the perspective of three sector economy, what are the main factors that affect the movement of is curve? How do they affect is curves
2. What is open market business? How does the central bank conct open market operation in the period of economic depression
3. What is acceleration principle? How to explain the cause of business cycle with multiplier accelerator model< In 2008, 670000 small businesses in China were forced to close down under the pressure of the global financial crisis. Chen Quansheng, counsellor of the State Council, said at a forum in Beijing on December 18, 2008 that about 6.7 million jobs have evaporated, mainly in Guangdong, the export base, making the number of unemployed far higher than the official figure of 8.3 million. The rising unemployment rate has exacerbated people's concerns about social stability. China's economic growth rate is expected to be less than 8% next year, which is regarded as the lowest level to maintain social stability
Chen Quansheng urged the vigorous development of labor-intensive instries to create employment opportunities and make up for the loss of employment opportunities e to shrinking exports and the government's control of growth in the past. In order to stimulate domestic demand, Beijing issued an economic stimulus plan worth 586 billion US dollars in November 2008, focusing on infrastructure construction

1. × two × three × 4.√ 5. × 6.√ 7. × eight × 9.√ 10. ×< Solution: (1) NDP = GDP depreciation = GDP (total investment net investment) = 5400 (2 points)
(2) net export = GDP consumption total investment government purchase = 100... (1 point)
(3) because: government budget surplus = government tax government purchase transfer payment
so: government tax transfer payment = government budget surplus + government purchase = 1130... (2 points)< (4) personal disposable income = GDP tax + transfer payment = GDP (tax transfer payment) = 6000-1130 = 4870)...... (2 points)
(5) personal savings = personal disposable income personal consumption = 870)...... (1 point)
2. Solution: according to y = C + I, y = 800 + 0.6y + 7500-20000r, According to m / P = L, LM equation is y = 6 + 10R (2 points)
simultaneous is and LM equation is r = 0.4, GDP = y = 10 (2 points)
3. Solution: (1) according to known conditions, y = C + I + G = 5 + 0.75 (y-4) + 6-0.25r + 18, The is equation is y = 104-r (2 points)
let L = m / P, and the LM equation is y = 200 / P + 12.5r (2 points)
combine is and LM equation, and the total demand equation is y = 96.3 + 14.8 / P (2 points)
(2) substitute P = 4 into the total demand equation, The results are as follows: (1) according to the real interest rate = nominal interest rate - inflation rate,
nominal interest rate = real interest rate + inflation rate,
the annual nominal interest rates are 14%, 16% respectively 19%... (3 points)
the three-year average nominal interest rate is 16.3%... (1 point)
(2) according to the real interest rate = nominal interest rate inflation rate, we get:
inflation rate = nominal interest rate real interest rate, so the expected inflation rate is 5% (2 points)
1, That is, the change of spontaneous consumption and spontaneous investment. The increase of spontaneous expenditure leads to the increase of the intercept of the is curve on the vertical axis, which leads to the right shift of the is curve. Its economic meaning is: even if the interest rate r remains unchanged, the national income y will increase 2 points)
(2) changes in government expenditure. When the government expenditure increases, the intercept of the is curve on the vertical axis becomes larger, so the is curve moves to the right, and the range of movement is △ y = kg ·△ G. This reflects the impact of expansionary fiscal policy 2 points)
(3) tax changes. When the tax increases, the intercept of the is curve on the vertical axis becomes smaller, so the is curve moves to the left, and the range of movement is △ y = kt · △ t
No, propensity to consume includes average propensity to consume and marginal propensity to consume. The average propensity to consume refers to the proportion of consumption expenditure to disposable income, and the marginal propensity to consume refers to the ratio of the increased consumption to the increased disposable income (the ratio of the increased consumption to the increased disposable income)
consumption tendency can not summarize all the factors that affect consumption. It's just one aspect of consumption. Consumption will also be affected by the level of commodity prices, interest rates and other factors. Keynes believes that the most decisive factor in influencing consumption is household income. Therefore, Keynesian theory analyzes the influence of disposable income on consumption separately
extended data
average propensity to consume, also known as propensity to consume, refers to the proportion of consumption in income. If expressed by formula, it is: APC = C / y
for example, a social income is 2 trillion yuan, consumption expenditure is 1.5 trillion yuan, and average propensity to consume is 0.75 (1.5 / 2)
The changes of APC and MPC have the following basic rules:(1) the average propensity to consume APC and the marginal propensity to consume MPC are decreasing, that is, because of the increase of income, consumption also increases, but the growth rate of consumption is smaller than the growth rate of income (APC decreasing), and smaller and smaller (MPC decreasing). The decline of APC and MPC is an important viewpoint of Keynes, which is one of the three laws of Keynes to explain the lack of effective demand
(2) MPC is the slope of the consumption curve C = C0 + by, and the slope of each point on the consumption curve should be equal, but in the long run, the slope of the consumption curve is getting smaller and smaller3APC> MPC, as can be seen from the comparison of APC and MPC figures in table 10-1. This is because even if the income is zero, there will be basic consumption C0. MPC should be less than 1, but greater than zero
wealth effect in a broad sense refers to a broader concept covering all wealth, including material and spiritual effects. Wealth is the material goods that can meet your needs in proction and life; Wealth is what makes you happy in spirit
