Testing the unit root hypothesis against TAR nonlinearity using STAR-based tests

Author

  • Sollis, Robert

Abstract

This paper investigates the finite-sample power of STAR-based unit root tests when the data generation process is a globally stationary three-regime TAR model. Unit root tests are proposed derived from STAR models that nest TAR models.
