Question 2

The following is not a consequence of Xt and Yt being cointegrated:
 
  A) if Xt and Yt are both I(1), then for some , Yt   Xt is I(0).
  B) Xt and Yt have the same stochastic trend.
  C) in the expression Yt   Xt ,  is called the cointegrating coefficient.
  D) if Xt and Yt are cointegrated then integrating one of the variables gives you the same result as integrating the other.
