  2. Background • Trade margins are an important input factor in the SNA • Trade margins in today’s Swedish SNA is deficient • Higher quality would be a significant improvement of the SNA Trade Margins

  3. 511 Trade agents; 34 146; 3% 519 Other wholesale; 3 666; 512 Agricultural raw 0% materials and live animals; 518 Machinery, equipment 17 739; 2% and supplies; 223 035; 21% 513 Food, beverages and tobacco; 174 189; 17% 514 Household goods; 234 798; 22% 515 Non-agricultural intermediate products, waste and scrap; 366 761; 35% NACE 51 in Sweden 2006 Turnover, SEK million Total turnover: 1 054 SEK billion (≈160 USD billion) No. of enterprises: 44 000 Trade Margins

  4. Stratification and sample • Aim: cover all products required by NA • 4- or 5-digit NACE level • Larger heterogeneous industries -> larger samples • Smaller homogeneous industries -> smaller samples • Cut-off strategy – largest enterprises within each industry Trade Margins

  5. Estimation [ 27 * (1 - 0,18) = 22,14 ] etc. Trade Margins

  6. Estimation etc. Trade Margins

  7. Estimation etc. Trade Margins

  8. Variables • 41 turnover variables in SBS • 250 goods product groups in SNA • 129 variables in TMS with turnover and margin required • Excluding VAT and other taxes Trade Margins

  9. Coordination with SBS • Minimise sample size • Total trade turnover and cost available in SBS, considered to be of good quality • Reduction of sample size from 3 000 to 600 • Simplify for respondents • Possible to pre-print as much information as possible (total turnover, trade turnover, trade cost, some turnover specifications) Trade Margins

  10. Questionnaire design • Basic information (total turnover, trade turnover etc.) • Specification of trade turnover and margin per detailed product group • Pre-printed if possible • Variation depending on sub-industry and possibly previous information (SBS) Trade Margins

  11. Example of questionnaire – pre-printed Trade Margins

  12. Example of questionnaire – not pre-printed Variables depending on industry Trade Margins

  13. Response rate • 67 % un-weighted, 55 % weighted • Possible reasons: • Response burden (SBS) • Sensitive information Trade Margins

  14. Results matrix Trade Margins

  15. Problems • Sensitive information • Problems with getting hold of the information • Refined / non-refined goods • Response burden Trade Margins

  16. Conclusions • Preliminary analysis show results are satisfying • NA will make a more thorough analyse • Business Structure Unit will also analyse results to see if they could be used internally • Decision on if / when to conduct survey again Trade Margins
