We consider the stability under adaptive learning of the complete set of solutions to the model when . In addition to … representation used by agents in the learning process. Only the finite-state Markov sunspot solutions can be stable under learning. …

The recent macroeconomic literature stresses the importance of managing heterogeneous expectations in the formulation of monetary policy. We use a stylized macro model of Howitt (1992) to investigate inflation dynamics under alternative interest rate rules when agents have heterogeneous...

We study the properties of generalized stochastic gradient (GSG) learning in forward-looking models. We examine how the … conditions for stability of standard stochastic gradient (SG) learning both differ from and are related to E-stability, which … governs stability under least squares learning. SG algorithms are sensitive to units of measurement and we show that there is …
