Abstract
The study concentrated on demonstrating how nonlinear modelling can be useful to investigate the behavioural of dynamic economic systems. Using some adequate nonlinear models could be a good way to find more refined solutions to actually unsolved problems or ambiguities in economics. Beginning with a short presentation of the simplest nonlinear models, then we are demonstrating how the dynamics of complex systems, as the economic system is, could be explained on the base of some more advanced nonlinear models and using specific techniques of simulation. We are considering the nonlinear models only as an alternative to the stochastic linear models in economics. The conventional explanations of the behaviour of economic system contradict many times the empirical evidence. We are trying to demonstrate that small modifications in the standard linear form of some economic models make more complex and consequently more realistic the behaviour of system simulated on the base of the new nonlinear models. Finally, few applications of nonlinear models to the study of inflationunemployment relationship, potentially useful for further empirical studies, are presented.
