Initial 2003 Scottish Input-Output Tables

1. Initial 2003 Scottish Input-Output Tables

2. Changes in the New System • Producing a Combined Use matrix • Balancing at Purchasers’ Prices • Manual Balancing – more focussed • Less Reliance on RAS

3. Changes in the New IO System • More Efficient IT system • Flexible System • Tax and Margins System rewritten

4. Current Position • System has now been almost fully run • Initial 2003 balance produced • Manual Balancing has been heavily used in this process • Coding to produce the symmetric tables has still to be incorporated

5. Methodology Changes • GCS Imports data • PRODCOM data imputed for missing values • 2003 Purchasers Inquiry • More use of ABI data • Combined Tables • Manual Balancing

6. RASing Process • Manual balance adjusts total intermediate consumption in USE table (Input of industries) • Adjust Make table to match USE (Output of industries) • Increases to Make subtracted from Imports to keep balanced commodities • 9 IOCs excluded from Make adjustments because imports less than required increase in Make • Adjusted Supply totals provide desired column and row totals for USE table

7. Future developments • Production of Consistent Time Series of Input-Output tables. • Work will begin on a detailed revisions policy for Input-Output • Tailor-made responses to queries
