Research output: Contribution to journalArticle


We show that the two-variable VAR model of Blanchard and Quah (1989) produces results identical to those based on the Sims (1980) orthogonalization if the first-ordered variable is not caused in the long run by the second-ordered variable. Some illustrative examples are provided to demonstrate the usefulness of this result.
