Unit Root Tests Based on Instrumental Variables Estimation


  • Lee, Junsoo
  • Schmidt, Peter


This paper develops new tests of the unit root hypothesis based on instrumental variables estimation. The tests are asymptotically valid in the presence of moving average errors and they are quite accurate in finite samples. They are more powerful against stationary alternatives than other tests that are equally accurate under the null.
