4. 2. Some features of the present SUT-system • SUT leading for estimates of (volume growth of) GDP and details, annual and … quarterly! • Final annual estimates (year t-3): 250 industries x 800 product groups • Provisional annual estimates (years t-2 and t-1) and quarterly estimates: 100 industries x 200 product groups • Annual change of weighting scheme for volume and price measurement, including chaining

5. 2. Some features of the present SUT-system • Simultaneous integration of SUT in current prices and prices of the previous year: 6-pack approach: • Laspeyres volume index and Paasche price index => additivity of data in prices of previous year • Fully automated derivation of input-output tables (industry x industry) • Description Data • T at current prices Price index 215 102.4 • T at prices of T-1 Volume index 210 105.0 • T-1 at prices of T-1 Value index 200 107.5

6. 3. Organisation and process • Centralised input of source data (except for government and financial corporations) • Further processing of source data by “column” specialists (industry resp. final expenditures): adjustments for discontinuities, hidden activities, ESA-definitions, etc. • Integration by “row”: project leader and “column” specialists • Check and double-check meeting: • Confrontation with sector accounts and labour accounts • Plausibility checks and discussion • Advice to management

7. The making of... • Dutch practice • From source to I/O • Source data • surveys and register data • Adjustments to national accounts requirements • Exhaustiveness, definitions, price and volume, specifications, plausibility checks (volumes) • Balancing • Globalization, black economy, sampling errors, plausibility checks (prices and volumes) • Transformation to I/O-tables • Industry by industry

8. 3. Organisation and process • Relationship with providers of source data: • Service Level Agreements (SLA): planning and contents of data deliveries, quality indicators, contents of quality reports • Communication and feedback (subject for further improvement): e.g. meetings and discussion between NA-specialists and data providers

9. 4. Benefits of SUT system • Benefits: • Reliable estimates for macro-economic variables: check for basic identities, detect inconsistencies & white spots • Provides detailed picture of production processes in a country: what produced, with what inputs, and sold to whom • But: • The higher the level of detail and/or • The more recent the covered time period (quarters!) • The larger the influence of assumptions!

10. 5. Future challenges and redesign of NA-system • External developments: • More data from registers, less data from surveys • Globalisation => measurement and conceptual problems • Transparency and reproduction • Efficiency and budget cut backs • Redesign of NA-system: • Discussion with major users • Benchmarking with other NSI’s • Research future methodology and architecture => consequences for statistical process as a whole

11. 5. Future challenges and redesign of NA-system • Research future methodology and architecture • From goods to services • From SUT to income data (what about prices?) • Less details in SUT • Consequences for statistical process as a whole: • Focus of NA on integration of data (adjustments at the source) • Micro-integration of large and/or “complicated” enterprises • Estimates for small/medium enterprises: almost fully register based • National data => European data
