Sequential Action and Beliefs under Partially Observable DSGE Environments

  • Seong-Hoon Kim

This paper introduces a classification of DSGEs from a Markovian perspective, and positions the class of POMDP (Partially Observable Markov DecisionProcess) to the center of a generalization of linear rational expectations models. The analysis of the POMDP class builds on the previous development in dynamic controls for linear system, and derives a solution algorithm by formulating the equilibrium as a fixed point of an operator that maps what we observe into what we believe.
