Supply and use tables Sector accounts SAM NAMEA RA TSA 1. Dutch system of NA in general Labour accounts

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

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) DescriptionData T at current pricesPrice index T at prices of T-1Volume index T-1 at prices of T-1Value index

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

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

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

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!

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

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
