26. It is a kind of consumer utility that reaches the maximum and remains unchanged. In the sense of cardinal utility, the condition of consumer equilibrium is MU/P=λ, where λ is the marginal utility of money; In the sense of ordinal utility, when the indifference curve is tangent to the budget constraint line, consumers are in equilibrium, provided that RCS1,2=P1/P2.

27. It refers to an industry in which the cost of manufacturers does not change with the increase of the number of manufacturers in the industry (or the total output in the industry).

the long-term supply curve of this industry is a horizontal straight line.

28. Also known as monetary GDP, it refers to the market value of all final goods and services of a country calculated at current prices. The level of nominal GDP is influenced by price factors, and the actual productivity may be overestimated or underestimated by using nominal GDP.

29. in a two-sector economy, a function that represents the relationship between residents' consumption and total income. The function form is: C=C(Y), consumption is the increasing function of income, but with the increase of income, the increase of consumption quantity can't keep up with the increase of income.

IV. Calculation problem (8 points)

3.(1)IS curve: 3-1r=-2+.2Y

LM curve: .4Y-5r=25

(2) Solve: 3-1r =-2+.2y

.4y-5r = 25

and get: Y=1

r=3

(3)C=1, Then the IS-LM equation is

1+3-1r =-2+.2y

.4y-5r = 25

and the solution is: Y=11, so the national income increases by 1.

31. Generally speaking, the higher the price of a commodity, the smaller the quantity of the commodity that consumers are willing and able to buy, that is, the demand; On the contrary, the lower the price of goods, the greater the demand. In western economics, this feature is called the law of demand. The demand curve that meets the demand law is inclined to the lower right. The law of demand gives the basic characteristics of consumers' demand for goods. But this does not mean that all consumers' behaviors strictly obey this rule. The following three situations can be regarded as special cases of demand law.

first, consumers need something.
