Chapter 32 Sunspot equilibria in sequential markets models Equilibrium with rational expectations is a central construct of modern economic theory. The chapter studies surveys which are primarily aimed at assessing the properties and relevance of this construct in a general equilibrium framework; in particular they are related to the issue of multiplicity of rational expectation equilibria. The viewpoint discussed in the chapter is associated with the so called concept of sunspot equilibrium. It focuses on aspects of general equilibrium with rational expectations that have been given a central role in recent literature. It presents the problem of sunspot equilibria in the broader perspective. It also discusses an example of sunspot equilibrium and a simple economic systemnamely a sequential economy with infinite horizon and time independent structure. Furthermore this economy is one step forward looking and has no predetermined variable.
