If two variable Xt and Yt are cointegrated, then the OLS estimator of the cointegrating coefficient is consistent. However, the OLS estimator has a nonnomal distribution, to have right inferences we have to use ……
a- The DOLS (Dynamic OLS) estimator with HAC standard errors.
b- The DOLS (Dynamic OLS) estimator only.
c- The OLS estimator with HAC standard errors.
d- B or C.
