  1. EPUNet Training Course 2005Day 1Tutors: Olaf Jürgens and Christian SchmittBerlin, April 11th to April 15th 2005

  2. Overview • Questionnaires • PDB vs. UDB • Ex-Post vs. Ex-Ante Harmonization

  3. Questionnaires PDB Questionnaires (Production Data Base) PDB contains the following files: • Personal File • Household File • Personal Register File • Household Register File This is the data that was collected in the field

  4. Questionnaires UDB Questionnaires (User Data Base) UDB data is based on a conversion of PDB data that is similar for all countries Central tool for getting information • ECHP UDB Description of Variables (Doc-Pan 166) Codebook referring to ECHP contents and cross national differences

  5. ECHP Participation across Europe ECHP consists of 8 waves All countries 1994 to 2001 except: • Austria (1995-2001) • Finland (1996-2001) • Luxembourg (1995-2001) • Sweden (1997-2001 cross-section only!)

  6. From PDB to UDB ECHP Data generation – two step process • PDB vs. • UDB PDB: Collecting the data in the field by NDUs (National Data Units) Transmission of data to EUROSTAT UDB: Converting national data using a generalized algorithm into User Data Base format

  7. Ex-Ante (Input) Harmonization Concept: Unique set of questions as basis for a cross national comparable data-set True for all countries except • Luxembourg (PSELL, 1995-2001) • Germany (SOEP) • UK (BHPS)

  8. Ex-Ante (Input) Harmonization Concept: Unique set of questions as basis for a cross national comparable data-set Further Exceptions: • Timing of national panels • Cloning of national data sets • Differences in modes of data collection • Differences in national settings (policy settings, etc.)

  9. Ex-Post (Output) Harmonization Data is transformed (cloned) to fit a unique concept after data collection • Luxembourg (PSELL) (wave 2, 1995) • Germany (SOEP) • UK (BHPS) Both (bold) starting with wave 1 (1994) • Limitations • Advantages

  10. Ex-Post (Output) Harmonization Limitations • Different tracing rules • Different panel mortality structure Coverage of questionnaires: • Inconvertible variables • Unavailable variables • Different wording of variables • Different contents of variables

  11. Ex-Post (Output) Harmonization Unavailable Information: Luxembourg • Labour market related variables • Household durables • Education/Training • Health • Care • Migration • Life satisfaction

  12. Ex-Post (Output) Harmonization Unavailable Information: UK • Financial Situation (Household) • Employment related information • Health • Care • Life satisfaction

  13. Ex-Post (Output) Harmonization Unavailable Information: Germany • Household durables • Health • Care • Migration • Life satisfaction (problems of scale) • Current (Re-)Training and Education

  14. Ex-Post (Output) Harmonization Advantages • Reliable data sources • Available range and depth of information • Flexible integration of country-specific settings and concepts

  15. Input/Output Harmonization For more details on ECHP related harmonization see: Roland Günther (2003): CHINTEX Working paper #19.http://www.destatis.de/chintex/proj_des/wp_1.htm

  16. Files to use • PDB-UDB.xls • Country-File (as example for the two German samples)
