Methods for constructing joint confidence bands for impulse response functions
which are commonly used in vector autoregressive analysis are reviewed.
While considering separate intervals for each horizon individually still seems
to be the most common approach, a substantial number of methods have been
proposed for making joint inferences about the complete impulse response
paths up to a given horizon. A structured presentation of these methods is
provided. Furthermore, existing evidence on the small-sample performance
of the methods is gathered. The collected information can help practitioners
to decide on a suitable confidence band for a structural VAR analysis.
