

Revised National Accounts Data



Revised SNA 68 -> SNA 93



Revised Base Year



Initially estimated lower due to lack of data or capacity



Most likely due to currency changes

Initially estimated higher, due to using “good economic year” as base year



No Revision

Conclusions/ issues to discuss

• Critical to publish updated ICP 2005 results

 Simple Economic Change  Revisions of methodology  Other

• Possible steps for updating 2005 PPPs

 Obtain revised 2005 National Accounts data from countries  Use revised 2005 Expenditure Data and ICP 2011 methodology to compute Final 2005 PPPs

• Issues

 Which level of revised expenditure data to ask for countries? (GDP/ Aggregates/BHs)  Use of other International Database  Timeline / coordination
