This paper proposes a simple model composed of an investment equation and a productivity relationship. It shall serve as a vehicle to investigate the dynamics of changing growth paths. While descriptive analysis of the growth rates of such time series on a disaggregated level has typically shown cyclical movements or structural cycles the process of identifying growth traverses in two variables of central importance for the growth process has not received much attention. But instead of analysing the full set of economic sectors of an economy this paper will concentrate on the aggregate. After a short introduction into the basic economic assumptions an empirical study of the French growth process will be presented. As basic tool this investigation uses the smooth transition regression approach. Starting from linear specifications the model will be tested for missing nonlinearities. After appropriate re-specification and tests for no remaining nonlinearity the model is analysed as to its dynamic properties.
