Principles of Ring Linking 1. Ring product list is created (because Regional lists have limited overlap); 2. Regional fixity is retained at BH level; 3. Regional BH parities are produced with CPRD; 4. Ring Region is used for linking only [with a CPRD- style index].
FIXITY Item level BH level GDP level All aggregates
Fixity at the GDP level (OECD) Version 1. Running full global BH matrix, with each OECD country as a separate entity, then the OECD total is redistributed on the basis of the regional OECD comparison. Version 2. Creating an OECD country to be included in the global comparison, then the OECD countrys GDP is redistributed on the basis of the regional OECD comparison.
