Publisher's Note: Error in section: Re-evaluating the Data: Inconsistencies and Omissions

We replicated the author's fixed effects model (Arellano-Bover/Blundell Bond model).

There was an error in the second paragraph of this section. The correct sentence is: We approximated the author’s fixed effects model and Arellano-Bover/Blundell Bond model.

Note: Since the specifications for these models have not been disclosed, the authors approximated them without including controls for GDP and general government expenditure.
