How to calculate effective demand in economics questions

Effective demand refers to the aggregate social demand that is expected to bring the greatest profit to the employer (enterprise), and the effective demand is the aggregate social demand that is equal to the aggregate supply and the aggregate demand so that it is in equilibrium, which includes consumption demand (consumption expenditure) and investment demand (investment expenditure), and determines the size of social employment and national income. That is, the aggregate demand of society that is equal to the total supply of society and thus in a state of equilibrium. In the twenties of the nineteenth century, the concept of effective demand emerged.

The theory of effective demand and supply is something that will be talked about in economics, so it is divided into two aspects to explain what is effective demand and what is called supply theoryI don't think it's difficult to do this, because when I studied microeconomics as an undergraduate, I should have talked about it. <>

Effective demand is to say that there is demand in the market for this thing, but these people who have demand are people who really have the ability to buy, suppose I am a provider of goods, I am now selling a mobile phone market ** price of 2500 yuan, want to form an effective demand, the person who meets the definition of effective demand must be he wants to buy my mobile phone, and then he also has the actual ability to buy, this is called effective demand, if Zhang San he likes my mobile phone very much, but he has no money, he said I will be 500 yuan, Can you sell it to me cheaply? I said no, he said I'm a student, I said no, you can't be a brute, so then he doesn't count as a valid need. <>

The supply theory is that the supply in the market is proportional to the change between the supply in the market, the higher the supply, the more, the lower the supply, the less, pay attention to the causal relationship, which is the impact of supply. Economically, supply and demand do affect supply and demand, but it also affects supply and demand, and vice versa. Or the above mobile phone, if the market is 3000 yuan, then I will definitely produce more of this mobile phone, because my cost has not changed anything, but my profit margin is moreIf it drops to 1500, then I think my cost hasn't changed, and I don't make any money now, so I'll produce less, or even not produce at all.

Therefore, the theory of effective demand and supply should be some conceptual things, which are a basis in microeconomics and macroeconomics, if you don't understand this effective demand, then it may be more difficult to involve some more complex concepts in the future, if you are studying economic management, financial management, financeYou may all learn that economics is Western economics, it is divided into the first volume, the second volume, macro and micro, this thing is good to learn, which is helpful for future learning.

Effective demand refers to the aggregate social demand that is expected to bring the greatest profit to the employer (enterprise), and the effective demand is the aggregate social demand that is equal to the aggregate supply and the aggregate demand so that it is in equilibrium, which includes consumption demand (consumption expenditure) and investment demand (investment expenditure), and determines the size of social employment and national income.

Effective demand means that what is given comes in handy right away. The assumption is the calculation, if there is a supply condition. What is the benefit to be obtained.

First of all, within a fixed period of time, to bring the owners the maximum profit of a demand, first of all, to meet the social supply and demand balance relationship, must achieve a very high consumption capacity and consumer demand.

Answers]: a, d

In economics, the demand refers to the quantity of a certain commodity that consumers are willing and able to buy at each ** level in a certain period of time. When a consumer wants to buy a certain kind of business resistance and has the ability to pay, the real demand can be formed.

Answer]: B As far as general commodities are concerned, the relationship between demand and ** shows reverse changes, that is, in the case of other factors, the higher the ** of the commodity, the lower the demand for the commodity, and vice versa. This kind of pure rotten relationship is called the law of demand.

Answer]: B As far as general commodities are concerned, the relationship between demand and ** shows reverse changes, that is, under the condition that other factors remain unchanged, the higher the price of the merchant is buried in the goods, the lower the demand for the commodity, and vice versa. This relationship is known as the Law of Demand.

You mistyped the numbers in your question, and you can't figure it out. (3) If G increases by 50, then there should be what the original G is, and the investment function should be i=20-2r. Here's the idea.

1) From y=c+i(+g), the IS equation (a relation between y and r) is obtained, and from l=m p, the lm equation (a relation between y and r) is obtained, and these two equations are the aggregate demand function.

2) Substituting p=20 and 5 into the lm equation obtained from (1), and then concatenating the IS equation to solve the total demand y

3) Same as (1), find the IS and LM equations (i.e., the aggregate demand function) and then substitute P=10 and 5 into the LM equation, and the simultaneous IS equation solves the aggregate demand Y(4)is equation is the same as that obtained from (1), and the money supply increases by 20, that is, M=70, then the LM equation becomes L=M P=70 P

Finally, the simplified is and lm equations are the aggregate demand function.

Curve: y=c+i+g=

LM curve: Combining the above two equations to obtain national income and interest rate.

2.At this point, g is assumed to be unknown. Bring Y 3600 into the LM curve to get the interest rate, then bring Y and R back to the IS curve to solve the new G, and then compare it with the original 100.

3.At this point, it is assumed that the money supply is unknown. Bring Y 3600 into the IS curve to get the interest rate R, bring Y and R back to the LM curve to solve the new money supply, and then compare it with the original 1000.

4.Similar practices to 2 and 3 will not be repeated.
