  1. PRODUCER PRICE INDEX FOR WIRED, WIRELESS, SATELLITE AND TELECOMMUNICATIONS SERVICES IN GERMANY 2008 MEETING OF VOORBURG GROUP

  2. DEFINITION OF THE SECTORTelecommunications comprises transmission of • voice, data, text, sound and video • content, without being involved in its creation

  3. Structure of the German market • 63.6 Bill EUR turnover in 2006, thereof • - 20.5 Bill EUR fixed line telephony • - 22.1 Bill EUR mobile Phone services • - 0.8 Bill EUR leased lines • - 7.4 Bill EUR interconnection • - 3.0 Bill EUR cable TV • - 9.8 Bill EUR other services

  4. Challenges of TC for price statistics Market characteristics • rapid changes in technology • permanent introduction of new services • strong competition between companies • large changes in the market position of companies

  5. Challenges of TC for price statistics Statistical challenges • good timing for introduction/dropout of services • Handling of changes in the condition of services • quality adjustments for new services • handling of bundles • sensitiveness of data

  6. CPI and SPPI for TCcalculation within one unit • Advantages • persons have + a good expertise of the markets + good contacts to companies • dual use of information • but - separate calculation procedures for CPI and SPPI

  7. Development of the German SPPI for TC • In 2006 coordinated work started to revise the CPI and to develop the SPPI • Work in two stages: • obtaining the weighting data for CPI and SPPI • developing the current surveys for SPPI • The existence of a legal obligation made work much easier than in a previous pilot phase 2003/2004

  8. Cooperation with the regulator • In Germany the regulation authority is not allowed to pass individual statistical data to Destatis • but Destatis got much technical advice from regulator • regulator‘s annual questionnaires were used as a basis for statistical questionnaires • results were cross checked • statistical questionnaires contained weighting information required for CPI and SPPI

  9. Business to Business- and Business to All-approach • SPPI-concepts: • OECD/Eurostat task force: • all sectors including the public sector or private householders • EU-regulation 1158/2005 (concerning short term statistic  STS-regulation) • covers only services delivered to customers that are enterprises business to all business business to

  10. Business to Business- or Business to All-approach According to recent EU recommendations Germany follows the Business to All-approach

  11. Sample design - Cut-off sample of all companies with a turnover of 100 Mill EUR and more - sample comprises 30 companies - covers 95% of the whole turnover of TC

  12. Collection of information • Unit value approach • Units observed are: • - Turnover and • - number of .. (e.g. participants) or • - minutes of telephone calls or • - GByte of data transmission

  13. Survey programme • Division into two categories: • - Fixed line telephony and internet use • - mobile telephony

  14. Main activities observed • Fixed line telephony/internet use • - Private final clients (minute prices by type of call, VoIP, flat rates, bundled products by types etc.) • - Business final clients (same breakdown as above) • - Wholesale of phone calls (specific breakdown per company) • - Leased lines • - Internet (e.g. provision and access via broad band/narrow band by type, flatrates)

  15. Main activities observed • Mobile telephony • - Private and business final clients (basic fee, calls into different nets, flatrates, prepaid cards etc.) • - Wholesale (contract clients, prepaid cards, calls by nets, etc.) • - National roaming (language, SMS, MMS, etc.) • - International roaming (see above)

  16. Flat rates and bundled products • - Increasing importance since 2006 • - flat rates common for fixed line telephony, mobile phone, Internet • - bundled products mainly fixed line telephony and Internet • - all types of bundled products exist (combination of flat rates and/or quantity related tariffs) • - shift to higher data transmission standards in Internet use (quality change) • - regular update of survey programme necessary

  17. Burden for companies • - Specific questionnaires for companies according to their activities. • - These questionnaires form a subset of the complete survey programme

  18. Calculation procedure • Separate computation for the sectors • - fixed line telephony/internet (no separation because of bundling) and • - mobile telephony • Company specific calculation (drastic changes of market share of market participants)

  19. Calculation procedure • - Per company service output is divided into homogeneous subsets for which value and quantity data are available • - indices per service output are calculated and aggregated at the level of the company • - indices for companies are aggregated to sectoral indices • - sectoral indices are aggregated to TC total
