Does traditional economic theory apply to mathematical economy?

First, China had economic thoughts as early as the Spring and Autumn Period, but it was not until the 20th century that economics began. /kloc-economics also appeared in the west in the late 20th century. Why is economics different from economic thought?

The key lies in whether there is a systematic analysis framework, which is not only conducive to the falsification of theoretical assumptions, but also convenient for the accumulation and inheritance of subject knowledge! In the current state of human knowledge, mathematics is the best tool to establish this framework. Second, yes, the existing mathematical economic theory has great limitations, and people who like these models have seen it, but it just shows that we still need to work hard, and we need more generations to work hard instead of giving up. Why is the existing mathematics limited? In the past, physical phenomena were the main reason for the development of mathematics. When they are used to analyze human society, it is not surprising that there are some mismatches. But the situation is changing, and more and more economic phenomena, including the financial crisis, are catalyzing new mathematics. Third, economics is one of the most suitable subjects for mathematicization. For example, next month's inflation, stock market, output, climate, agricultural output and so on.

Full of unknowns, these are the research objects of probability theory and stochastic process theory. Why shouldn't economics borrow them? Everyone who does business knows that it is easy to make money when the business is small, and the profit rate will be lower and lower when it is big. Isn't this a concave output function? Being an enterprise hopes to earn the most money. Isn't this an optimization problem? Fourth, is the institutional economics that everyone likes inseparable from mathematical economics? Zhang Wuchang denounced mathematical economics in this way. Is his theory possible without the influence of his previous mathematical model of economics? In fact, the most powerful thing about domestic mathematical models is that they either don't understand the essence of thorough mathematical economics, or they don't even know themselves after benefiting. Pick up the bowl and eat the meat, put down the chopsticks and curse the mother! Without the application of mathematics, there would be no modern economics. It may be said that Coase's theory is simple and easy to understand.

Mathematics, and the mathematics used in the new economic model is more and more abstract and biased! Frankly speaking, any use of mathematics in economics in the early 20th century was rejected. If we were not used to the authority of mathematics at that time and rejected all mathematics, would there be a later new institutional economics? New property right theory? Who can predict what mathematics will succeed in the future? Still have an open mind, people who use mathematics and those who don't use mathematics should be respected. 6. How can business and finance promote the development of mathematics? Why can't economics be separated from mathematics? Two thousand years ago, the ancestors of the Han Dynasty published the seventh volume of Nine Chapters Arithmetic, in which they asked, "Some people in Shu today hold money, thirteen. The first time 14000, the second time 13000, the second time 12000, the second time1000, and then 10000. Every five times, the profit dries up. Ask this how to hold money for mutual benefit? " Today's China Classic

Economics surpassed the Han Dynasty? Seven, write these, 1 Looking at many papers in domestic economic and social sciences in recent years, they basically stay in fact descriptions, repeat each other, and are irrelevant. Obviously, because of the lack of a logical and self-consistent analytical framework, the research is empty; It is hoped that more young students will come into contact with the mathematical economic model and understand its essence before commenting. Nobel Prize is not a fool. Mathematical models are indeed subject to human ability, but who knows where the limit of Taoist ability lies?
