From Input-output to SUT Jörg Beutel Productivity in the European Union: A Comparative Industry Approach Workshop Inter-Industry Accounts WP September 2005, Groningen
From Input-Output to SUT2 Introduction Objectives Outline of present data situation Discussion of missing data Transformation of use tables from purchasers prices to basic prices Transformation of supply and use tables to input-output tables The dual approach: Transformation of input-output tables to supply and use tables Empirical example of transformation for Austria 1995 Estimation of missing supply and use tables
From Input-Output to SUT3 Data Situation ESA 1995 Annual supply and use tables starting in year 1995 Five-yearly input-output tables 1995, 2000, 2005, etc. Submission mandatory for member countries of EU The tables Supply table at basic prices, including transformation into purchasers' prices Use table at purchasers' prices Input-output tables for total uses, domestic production and imports at basic prices Earlier years Very few supply and use tables available SUT mostly internal data for compilation of IOTs Various input-output tables with different classifications and price concepts were published
From Input-Output to SUT4 Period
From Input-Output to SUT5 Period
From Input-Output to SUT6 Challenge Collect supply and use tables from NewCronos (Eurostat) Compile missing supply and use tables Estimate valuation matrices (trade and transport margins, taxes) Establish supply and use tables at basic prices for total supply, domestic production, imports Earlier years Collect existing SUTs and IOTs Estimate supply tables for existing IOTs Various price concepts and various classifications Estimate use tables at basic prices for existing IOTs Estimate missing SUTs at basic prices for other years Comparison with National Accounts in NewCronos
From Input-Output to SUT7 Valuation matrices Different valuation matrices Trade margins (wholesale trade, retail trade) Transport margins (inland, water, air and other transport) Taxes on products (product taxes, VAT) Subsidies on products Price concept Transformation of use tables at purchasers prices to use tables at basic prices Transformation of input-output tables at producers prices to basic prices
From Input-Output to SUT8 Access to valuation matrices Access to valuation matrices for selected countries in the course of the Eurostat data submission programme Germany, Denmark and Austria Austria published valuation matrices on CD-Rom in Statistik Austria: Input-Output-Tabelle 1995 Tax matrices were published by Eurostat in Input-Output tables 1985 for Denmark, France, and Ireland covering 59 sectors.
From Input-Output to SUT9 Transformation of supply and use tables to basic prices
From Input-Output to SUT10 Price system of the input-output framework Basic Prices = +Taxes on products - Subsidies on Products = Producers prices (net of all VAT) + Non-deductible VAT = Producers prices (net of deductible VAT) + Trade Margins +Transport Margins = Purchasers prices (net of deductible VAT)
From Input-Output to SUT11 PRICE SYSTEM OF THE INPUT-OUTPUT FRAMEWORK FOR DENMARK 1985 (Mio. DKR)
From Input-Output to SUT12 Transformation of supply and use tables to IOTs Model assumptions Product technology assumption (Model A) Each product is produced in its own specific way, irrespective of the industry where it is produced. Assumption of fixed industry sales structure (Model B) Each industry has its own specific sales structure, irrespective of its product mix Industry technology assumption (Model C) Each industry has its own specific way of production, irrespective of its product mix. Assumption of fixed product sales structure (Model D) Each product has its own specific sales structure, irrespective of the industry where it is produced.
From Input-Output to SUT13 Transformation of supply and use tables to input-output tables
From Input-Output to SUT14 Model assumptions for transformation to IOTs Product technology assumption (Model A) Widely used by countries which publish product by product IOT Belgium, Denmark, Greece, Spain, France, Italy, Austria, Portugal, Sweden, UK, Estonia, Slovakia, Hungary Problems with negatives Analytical tables away from statistical sources Assumption of fixed product sales structure (Model D) Widely used by countries which publish industry by industry IOT Denmark, Netherlands, Finland, Canada, Norway, Hungary No negatives Close to statistical sources Other assumptions Hybrid technology (UK), Almon procedure (Test version for NL)
From Input-Output to SUT15 Transformation of input-output tables to supply and use tables
From Input-Output to SUT16 Transformation of input-output table to use table Data situation For earlier years often supply and use tables are not available If they exist they internal data of Statistical Offices for the compilation of IOTs. Required input data Input-output table and supply table Supply table can be derived from benchmark years and official national accounts data. The structure of supply tables is rather stable in time.
From Input-Output to SUT17 Model assumptions for transformation to SUTs Recommendation Use the complements of Model A for product by product IOTs and Model D for industry by industry IOTs. Product technology assumption (Model A2) Widely used by countries which publish product by product IOT Transformation to SUT is not creating negatives Assumption of fixed product sales structure (Model D2) Widely used by countries which publish industry by industry IOT Transformation may create negatives. If negatives are generated Model B2 is an option.
From Input-Output to SUT18 Transformation of SUT 1995 to IOT 1995 for Austria Statistik Austria Product by product IOTs were compiled which are based on product technology assumption (Model A) In the course of the transformation numerous small negative elements were generated. Large negatives are an indication for the mismatch of statistical sources with the technology assumption. The negatives were deleted in a manual balancing procedure. EUKLEMS transformation All 4 transformation models were compiled using SAS software with dynamic data exchange with Excel files The results of Model A were very close to the published IOTs.
From Input-Output to SUT19 Transformation of IOT 1995 to SUT 1995 for Austria EUKLEMS transformation Required inputs are IOT 1995 and supply table 1995 All 4 transformation models were compiled using SAS software with dynamic data exchange with Excel files The results of Model A2 were close to the published SUT. The manual balancing caused minor deviations for value added and intermediate inputs for most sectors. In some cases larger differences were caused which can be revised in a manual balancing procedure. GDP and components of value added and final demand are correct.
From Input-Output to SUT20 Projection of SUTs and IOTs Requirements Supply and use tables or input-output table at basic prices for base year Real growth rates for valued added of industries (EUK60) Real growth rates for final demand (private consumption, government consumption, gross fixed capital formation, change in stocks, exports) Real growth rate of imports
From Input-Output to SUT21 Updating input-output tables
From Input-Output to SUT22
From Input-Output to SUT23 Eurostat method The main advantages of the Eurostat update procedure Robust update procedure at low costs Limited data requirements Only official sources from New Cronos are used. Integrated estimation of all four quadrants of IOT No arbitrary changes of input coefficients as in RAS Row and column totals for intermediates derived not given Structure of final demand estimated during the iteration Consistency of supply and demand provided by io-model. Successfully implemented for DG Regio Evaluation of the European Structural Funds in Greece, Portugal, Ireland, Germany, Italy, and Spain Documentation of updating procedures in Eurostat Input-Output Manual
From Input-Output to SUT24 Updating supply and use tables
From Input-Output to SUT25 Recommendations Classification Data base of EUKLEMS should cover all 60 individual industries (A60) of ESA EUK60 requires the disaggregation of 10 additional industries. In consequence the supply and use tables will comprise 70 industries. The data base will always allow to aggregate the results to A60. Input-output tables Collect all input-output tables, also if supply and use tables are available. The input-output tables may be the only reliable source of import matrices. Transformation of use tables at purchasers prices to use tables at basic prices Establish a standard procedure for the transformation of use tables at purchasers prices to use tables at basic prices. Estimate or collect all recommended valuation matrices.
From Input-Output to SUT26 Recommendations Valuation matrices If valuation matrices are missing use reference year or reference country to blow up the valuation vectors of the supply table to a full size valuation matrix. Transformation of supply and use tables to input-output tables and vice versa Use appropriate technology assumption for the transformation of input- output tables to supply and use tables and the transformation of input- output tables to supply and use tables. Compilation of missing supply and use tables Use a projection model to compile the missing supply and use tables. The main aggregates (GDP, value added by industry, components of final demand) shall be compared with the macroeconomic data in NewCronos of Eurostat.
