Modern DSGE models are microfounded and have deep parameters that should be invariant to changes in economic policy, so … issues also cause parameter instability after policy changes in DSGE models. This paper will look at the implications of … parameter shifts for econometric policy evaluation, to see whether policy advice derived from DSGE models would have differed …

DSGE models in small samples. We compare these tests with ones based on direct inference (using the Likelihood Ratio, LR …
