On Identifying Structural VAR Models via ARCH Effects

George Milunovich / Minxian Yang
Published Online: 2013-05-03 | DOI: https://doi.org/10.1515/jtse-2013-0010

Abstract: We consider the local identification of parameters in structural VAR models with ARCH type errors. By establishing a mapping between the structural and reduced-form models, we provide a set of sufficient conditions for the joint identification of all parameters. Under these conditions, as the structural parameters are identified, various restrictions on the parameters can be tested in a standard manner. For example, the significance test for the ARCH effect in the usual GARCH formulation for a structural shock does not suffer the complications caused by a lack of identification encountered in univariate GARCH models.

Keywords: structural vector autoregression; SVAR; ARCH; GARCH; local identification
