This paper studies relationships between the local determinacy of a stationary equilibrium in the perfect foresight dynamics, and its local stability in dynamics arising from econometric learning procedures. There is no clear links in linear scalar economieds where agents forecast only one...

This paper studies the relationships between determinacy and stability under recurdive learning of rational expectations equilibria. The analysis is carried out within a non-stochastic linear temporary general equilibrium framework with predetermined variables (or memory). Determinacy of the...

This paper analyses an example of nonstationary stochastic endogenous fluctuations. It studies the existence of Markovian sunspot equilibria on the rates of growth in a linear one step forward looking economy with one predetermined variable. It is shown that asymptotically stable stochastic...

This paper compares the most significant expectational stability criteria that have been used to assess the plausibility of perfect foresight trajectories in forward-looking dynamical systems: determinacy of trajectories, absence of neighbour sunspot trajectories, and convergence of "evolutive"...
