Evolution of Economic Growth Models

Abstract

The economic growth models based on linear structures masked for a long time the instability phenomena. The nonlinearity concept seems relevant to explain many phenomena and in particular the economic fluctuations.In this chapter, firstly, we endeavor to describe the evolution of growth models: The linear models, then, models that highlight unstable behaviors (which do not necessarily result from nonlinear systems1) and finally models whose structure are of nonlinear type.
