Purpose The principal aim of this paper is to review three basic theoretical growth models, namely the Harrod-Domar model, the Solow model and the Ramsey model, and examine their implications for economic policies. Design/methodology/approach The paper utilizes a positivist research framework...

We provide sufficient conditions on the objective functional and the constraint functions under which the Lagrangean can be represented by a l'1 sequence of multipliers in infinite horizon discrete time optimal growth models

In this paper, we make use of the Sobolev space W 1,1 (R +, R n) to derive at once the Pontryagin conditions for the standard optimal growth model in continuous time, including a necessary and sufficient transversality condition. An application to the Ramsey model is given. We use an order ideal...
