Yes, but research proposals must be approved by both BEA and the other agencies.  In addition, BEA and other agencies do not use common identifiers, so staff of BEA and those other agencies must prepare ID bridges between their surveys.  At this time, ID bridges have been created only between BEA surveys and the Census’s economic surveys and only for the years 2007-2013.  The bridges provide a link between the BEA enterprise identifier and the Census firmid.
