Nonlinear Considerations on Economic Systems’ Behaviour

Recent work done within the CNCSIS IDEI ID_1046 financed project has resulted in some ideas related to complex system behaviour and to certain ways in which this behaviour may be described using nonlinear models especially in relation to the evolution of the PIB and its components. We are presenting here some of these results and the way an oscillatory response in industrial production may be used to determine the associated differential equation of evolution.
