Dummy variables and the VAR

Page 6: Dummy variables in the simple dynamic model.

The simplified model can be written as:

The expected value of the process and the cointegration relations becomes:

Page 7: Dummy variables in the simple dynamic model.

The dynamic properties of the data can now be expressed as:

where

It is easy to see that:
