In this article, we develop an analytical general equilibrium model of the equilibrium exchange rate. This theoretical framework allows us to identify the relevant set of variables which determinate the equilibrium exchange rate and to explore how theses variables influence the trajectory of the...

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...
