A new robust sign test for cointegration


  • Yujin Oh
  • Beong Soo So


We propose new tests for cointegration based on signs of the residuals of the conventional t-test. Our tests have the limiting normal distribution under the null hypothesis and are robust to heavy tailed disturbances. A Monte-Carlo simulation shows the new tests have a stable size property and are locally more powerful than that of Engle and Granger (1987) for heavy tailed error distribution.
