The difficulties associated with the appraisal of the determinacy properties of a three-dimensional system are circumvented by the introduction of a new geometrical argument. It first brings about a complete and easy-to-use typology of the eigenvalues moduli in discrete time three-dimensional...

In this paper, we consider a discrete time version of the endogenous growth model developed by Barro [1], but augmented in order to consider public production. Policy solutions are characterized to maximize the social welfare and stabilize the economy. More intervention is required under a...
