Robustness

31 Dec 2013 RDP 2013-14
Isaac Gross and James Hansen
An important question is whether the estimated VAR is consistent with our theoretical model. ... VAR, but are assumed to be a statistically independent AR(1) process in the theoretical model.

Motivation

31 Dec 2013 RDP 2013-14
Isaac Gross and James Hansen
In addition to the VAR IRFs, we also report the IRFs from our theoretical model in general equilibrium with endogenous reserves. ... Nevertheless, in view of the theoretical model's overall ability to match the VAR IRFs, we use these GMM estimates to
