Xiamen University's strongest guidance on economics review
This article will talk about how to cultivate economic thinking. With economic thinking, learning is easy.
Before we formally tell, let ’s take a look at the classic saying of the great economist Keynes: To some extent, a qualified economist must be both a mathematician and a historian, as well as a politician and philosopher. He must be as far away from the world as an artist and down to earth like a politician. It can be seen from this sentence that to study economics well, mathematics, history, and philosophy are essential, because it helps to learn economics better.
So, how to cultivate economic thinking? Candidates can start from the following aspects:
1. The foundation is not strong, it is tantamount to an air tower
Economic thinking can not be cultivated in one day or two. Without a solid economic theory foundation, talking about cultivating economic thinking is tantamount to building in the air. Therefore, the most important thing for candidates in the early stage is to lay a good foundation. in particular:
(1) Refer to the reference book designated by the reported institution to review and prepare for the exam. You can follow the beginner-intermediate-advanced difficulty review first. Candidates must remember: the foundation is not strong, shake the mountain! Lay the foundation honestly first.
(2) In the preliminary review, be sure to do the after-class exercises of the designated reference book. By doing exercises after class, on the one hand, you can judge whether the knowledge content in the book is mastered, and on the other hand, you can exercise your answering skills and improve your ability to solve problems by answering.
(3) Don't be content to understand the contents of the book. Understanding is useless. You must be able to explain the knowledge clearly in your own language, and will do the problem.
2. Mathematics is a tool, it is a lore weapon
As far as the postgraduate entrance examination is concerned, in most universities, the difficulty of postgraduate entrance examination for economics is intermediate or intermediate. Intermediate economics, with special emphasis on mathematical analysis ability. With a strong background in mathematics, it is easy to learn intermediate economics. It is important to note that candidates must continually try to clarify economic issues in mathematical language. To improve mathematical level, we can start from the following aspects:
(1) Try to transform economic problems into mathematical problems, because mathematics is rigorous and concise. For example, consumers pursue utility maximization, and the constraint is the budget constraint equation. Therefore, consumer theory can simply understand that maximizing utility under budget constraints. With the objective function and constraints, the next problem is a mathematical solution process.
(2) Students who are admitted to prestigious schools of economics recommend buying a reference book: Jiang Zhongyi, "Basic Methods of Mathematical Economics", Peking University Press. This book can be used as a reference book, which introduces a lot of mathematical analysis methods, and it is particularly beautiful.
(3) Mathematical analysis in the appendix of the textbook is very important, don't take it lightly. For example, in the appendix of Van Lien's Microeconomics: A Modern Perspective, candidates must take it seriously and deduce it.
(4) Remember: the derivation process is a method of solving problems! Candidates must think more and analyze more in the derivation process.
3. No matter how busy you can't stop thinking
Candidates must be aware that they cannot be content with reading alone and should keep thinking. For example:
(1) Consider the logical relationship between chapters and sections. Economics pays special attention to the analysis of the framework system. There is a strict logical relationship between chapters and sections. For example, the national income determination theory has three classic models, namely the simple national income determination model, the IS-LM model, and the AD-AS model. There is a deep relationship between these three models. (Product market), expanded to two markets (product market and currency market), and then to three markets (product market, currency market, and labor market).
(2) What is behind the knowledge points, such as why the long-term output is determined by aggregate supply and the short-term output is determined by aggregate demand? These contents are not summarized and summarized in the book, but they are indeed very important.
(3) Routine questions, such as calculation problems related to third-level price discrimination. Thinking generally will tell you what known conditions and what are required to solve. Remember: you can't just be satisfied with the problem, you must think more and analyze the problem routine. Once you have mastered the problem routine, you can write the problem yourself, and there is no problem in solving the problem.
4. After studying, we must pay more attention to the economic world
