Oscillatory Dynamics of GDP During the Crisis 2008-2013 Compared to the Industrial Production Evolution

GDP presents an oscillatory behavior in its dynamics that allows, as a different approach to usual cyclic behavior models, to analyze using various methods such as a Fourier transform of the data series and the roots of the associated second order differential equations that describe the process. Cycles are shown that correlate with the economic sectors to the generation of GDP. The approach based on an oscillatory system is giving a complementary method to understand economic dynamics.
