Abstract

In a simple OLG model, we analyze expectations coordination on a Stationary Sunspot Equilibrium (SSE), using an ‘‘eductive” approach in which agents forecast the forecasting of other participants through Common Knowledge assumptions. We characterize the local stability of a SSE in terms of labor supply elasticity, and we give two results of existence of locally stable SSE by means both of Poincaré-Hopf Theorem and a local bifurcation argument. Classification JEL : D84, D90, E37
