(The model has a common trend which limits the number of independent long-run restriction to just one.)

See here for more on our paper as well as Chapter 10 of the Kilian and Luetkepohl book.

Here is a figure from our paper that shows the range of impulse responses consistent with the BP news-shock identification:
