Specifying and estimating vector autoregressions using their eigensystem representation

Author

  • Krippner, Leo

Abstract

This article introduces the eigensystem vector autoregression (EVAR) framework, where VARs may be specified and estimated directly via their eigenvalue and eigenvector parameters. Eigensystem constraints control a VAR’s allowable dynamics, as illustrated with EVAR estimations guaranteed to be non-explosive.
