Encyclopedia - Classical dichotomy.
Distinguish between nominal and actual variables.
1 + real growth rate = (1 + nominal growth rate) (1 + inflation rate).
This formula variant is:
Nominal growth rate = real growth rate + inflation rate + real growth rate Inflation rate
Due to the last item "Real growth rate Inflation rateThe value of " is very small and negligible, so this formula is usually written as:
Real growth rate = nominal growth rate - inflation rate
Your question is whether this growth is nominal or real, if the nominal growth is 10%, inflation is 11%, the real growth is -1%; If real growth is 10% and inflation is 11%, nominal growth is 21%.
Generally speaking, the officially advertised GDP is nominal GDP, while the growth rate is the real growth rate.

Demand = supply and demand (equilibrium state).
That is, demand = p = a - bq = supply p = c + dq
Launched a-bq=c+dq
So q=(a-c) (b+d).
Substituting Q=(a-C) (B+D) into Demand=P=A-Bq or Supply=C+Dq or the same method can be used to find the equilibrium P=(Ad+BC) (B+D).
So when a=12, b=2, c=2, d=3, the equilibrium price p=(12*3+2*2) (2+3)=8, and the equilibrium quantity q=(12-2) (2+3)=2
When a is shifted to 22, the easiest way is to substitute the calculation, so p=14, q=4
-
The demand is equal to **, i.e. the two formulas are equal p(d)=p(s). q=(a+b) (c+d) p=a-b(a+b) (c+d), just bring the number in when it changes.

In the ascending phase, TP also rises, when MP reaches the maximum, the rise rate of TP is the maximum, when MP is greater than 0, TP rises, when MP is equal to 0, TP reaches maximum, and when MP is less than 0, TP decreases. Relationship: The slope on the TP curve is equal to the MP value.
Intersect with MP, before the intersection point, MP is higher than AP, after the intersection point, MP is lower than AP, because, before the intersection point, the MP curve pulls the AP curve up, and after the intersection point, MP pulls the AP curve down. Relationship: When MP is greater than AP, AP rises, when MP is less than AP, AP drops, and AP reaches the maximum value when MP is equal to AP.
11.Select the second stage. Because in the first stage, the AP is greater than the MP, the TP is always increasing, at this time it is profitable to increase the input, all the way to the second stage, and the third stage AP is continuously decreasing, the MP is negative, and the TP is on a downward trend, at this time, even if the element is free, it will not increase again, but will decrease until the second stage.
So choose the second stage of production.
12.Isoyield line: The trajectory of all the different combinations of the two factors of production that produce the agreed output when the technology is constant.
Features: 1. There are an infinite number of isoyield lines between any two curves, 2. Any two curves do not intersect, 3. The curve is convex towards the origin. Economic Significance:
Similarities: The final yields are equal. Differences:
The marginal substitution rate between factors is different, and the factor cost paid to achieve this output is different.
13.The title asks whether there are points with the same economic significance, and if so, I need to find different economic meanings. So, I think this topic is a bit problematic, how can you ask that?
First ask if there is a same, and answer yes, since it is the same, how do you ask me to find the difference? If you ask your teacher, the following is a personal answer: there are similarities, that is, the marginal substitution rate of this point is the same, that is, the proportion of the elements is fixed.
Difference: The yield they represent is not the same.
14.The slope of the change point on the yield curve is the marginal technology substitution rate. Economic Significance:
At a constant equivalence curve, the decrease in yield caused by decreasing l(k) and the increase in yield caused by increasing k(l) are equal. The marginal technology substitution rate of the relationship is equal to the ratio between the two elements (i.e., the value of the division).
15.When the output is constant, when the input of one factor is increasing, the quantity of each factor that can replace another factor decreases. Economic Implications:
The production technology of any kind of product requires an appropriate proportion between each factor, that is, the substitution between the factors is limited, and there will be an optimal substitution rate.

First of all, your first question, economics exam questions, of course, you should refer to the primary macro and micro, each question is to write a lot of words, because every concept of economics is very rich, and is interrelated, the questioner hopes that you do not know a little about this concept, but understand it more comprehensively. If you really learn more solidly, you will find that you can associate a lot of each noun, and you will naturally gush endlessly.
It is said that the mathematical requirements of economics are high, in fact, we have to talk about the development of economics, because the research of economics at the beginning was qualitative, and now the country pays more attention to quantitative analysis, and the deeper the economics is, it is to engage in mathematical models, data analysis, and graphical analysis. to intermediate and advanced macro and micro, that is, the master's and doctoral stage. The study of mathematical methods is more important in colleges and universities, after all, you can't be called ** without data and models in it.
There are many branches of economics, and if you study quantitative economics, mathematical economics, statistics, etc., you will definitely focus on mathematics. But if you study the history of economic thought and things like that, you don't pay much attention to mathematics.

Of course, you have to memorize to cope with the exam, but studying economics is not for exams, the ideas expounded in actual economics will change your view of the world, and now many people on the Internet always have the same opinion on certain things, and they are constantly arguing, if you systematically study economics, you will find how ridiculous some people are.
Finally, I quote Mrs. Robinson, a famous British female economist: "I studied economics just to avoid being deceived by economists!" ”

Economics is interesting! In fact, any knowledge will be interesting if you delve into it!
Economics is not a science subject in the full sense, many aspects also focus on analysis, and economics is mainly to solve the problem of life and social management, ** in life, and higher than life! Macro and micro analysis of socio-economic phenomena from all aspects!

Economics is very interesting, I don't study economics in college now, but I still have time to go to the library to find some economics books to read, you will understand how the world's best economists can destroy a country without Dong a soldier and a cannon, her requirements for mathematics are not very high, you can find one or two books about economics to see, such as the financial predator Soros.

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. >>>More
