ABSTRACT
In this article, we examine the effect of estimation biases – introduced by model misspecification – on the impulse responses analysis for dynamic stochastic general equilibrium (DSGE) models. Thereby, we use full and limited information estimators to estimate a misspecified DSGE model and calculate impulse response functions (IRFs) based on the estimated structural parameters. It turns out that IRFs based on full information techniques can be unreliable under misspecification.

Notes
1 Giesen-Scheufele (Citation2013) show that the systems approach is much more efficient than a single-equation set-up and both are equally robust to typical forms of misspecifications.
