This paper studies relationships between the 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 economies where agents forecast only one perods...

Bubble solutions of rational expectations models are identified by extra components that arise in addition to market fundamentals. In general there still exist many equilibrium paths relying on a minimal set of state variables, i.e., along which the number of lags that influence the current...
