ACTA UNIVERSITATIS DANUBIUS Vol 7, No. 4/2011 The Analysis of the Evolution of the Gross Domestic Product by Means of Fourier Development Catalin Angelo Ioan1, Gina Ioan2 Abstract. In this article, we will carry out an analysis on the regularity of the Gross Domestic Product of a country, in our case the United States. The method of analysis is based on the consideration of the development in the Fourier series of a function and testing in terms of the average absolute error of the nearest polynomial Fourier of real data are considered. The obtained results show a cycle for 13 years, the average absolute error being 3.69%. The method described allows an prognosis on short- term trends in GDP. Keywords. GDP; cycle; Fourier JEL Classification: C65, E17 1. Introduction In the literature, the economic cycle designate the fluctuations which accompany the evolution of a nation or, sometimes, it simply is associated with the increasing and decreasing of an economy.
