In this paper we present a theoretically founded procedure in order to check for saddlepoint stability of rational expectations models. The proposed device uses some specific perturbed finite time approximations of the models and allows for an explicit theoretical foundation. Numerical evidence...

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...
