Aggregation problem in DSGE model

Abstract

The aim of this paper is investigating the estimation bias of the standard New Keynesian DSGE econometric procedure in an environment comprising heterogeneous and interactive agents. In this case, the standard New Keynesian DSGE econometric procedures may generate spurious evidence in aggregate equations. On simulating the Ising model and processing the standard New Keynesian DSGE econometric procedure with Dynare, dramatic estimation bias is found. Particularly, the IS puzzle is found in the Ising model with different network structures. © 2015 IEEE.
