Interpretation Of Seasonal Fluctation Of Prices By Means Of Fourier Series In The Regional Market Agricultural Products

This paper studies the analysis of price fluctuation with periodic functions as infinite trigonometrically series in sine and cosine terms and presents the basic analysis of Fourier series with regard to its applications in price fluctuation. Data used for the analysis was collected by ZEF/UNESCO Khorezm project over a 97 month on weekly basis, during 01.05.2002–01.05.2013 yr. on Urgench market for ten commodities. The findings show that seasonal fluctuation is very high for fruits and vegetables in harvesting and before harvesting period, while it is not high for livestock productions, rice and wheat.
