In 2003, the BEA undertook comprehensive revisions of all NIPA data series. This resulted in a number of changes of data classification and data measurement, see [BEA Revision Notes] for more details.
In 2008, the Board of Governors revised the data construction of the financial wealth series in the flow of funds, see [BoG Revision Notes] for more details.
While the cointegration and forecasting results are all robust to the change in the data, the revision has affected the point estimates of the cointegration vector.
