Discussion On The Cyclical Nature Of International Cotton Prices

2008/7/22 0:00:00 58

Abstract: Taking the average annual price of international cotton in recent forty years as the object, this paper discusses the cyclical nature of international cotton price fluctuation, and analyzes the causes of its cyclical fluctuation. The corollary is drawn: the world cotton end inventory consumption ratio fluctuation cycle is the main reason for the cyclical nature of the international cotton price fluctuation, and the two have a strong negative correlation. Under mild inflation, the fluctuation of world economic growth rate is more consistent with the international cotton price fluctuation; under severe inflation, the impact of inflation on international cotton price is more decisive than the inflation induced economic recession on the international cotton price, which will promote the rise of international cotton prices; in the light of the current cotton market situation, the international cotton price is in the rising stage.
 
In a market economy, the cyclical nature of economic process means that the changing process of economic variables is controlled by a certain mechanism, and is embodied as a regular form or pattern. At the same time, economic process is different from objective physical process. It may be influenced by some stochastic factors, such as climatic factors, political factors, psychological factors, etc. Therefore, in the course of the whole economic operation, the change of an economic variable may be dominated by periodic rules, showing a more obvious upward trend, downward downward, and then upward upward cyclical movement, with obvious rules. At the same time, it will be found that this rule is not simply repeated, and each repeating unit will be different.
 
As an important economic variable, price is not only affected by supply and demand factors and changes, but also influenced by the psychological factors and changes of participants, and it will also be influenced by inflation and other factors. Together, these factors form a mechanism that affects prices. If this price fluctuation is cyclical, it is possible to predict the future price trend from the historical price trend.
 
As one of the most important economic crops in the world, cotton, as one of the most important textile materials, is in a more competitive market economy environment, regardless of its trade or textile industry. This article will take the international cotton price CotlookA index (annual average price, 1969/70 year 2008/09 year) as the object, from the international cotton price (nominal price) cyclical existence, the international cotton price cycle causes, as well as the international cotton price cyclical to the present cotton market enlightenment three aspects to discuss the cotton price cyclical. In this discussion, the data required are shown in Table 1.
