Workpackage 5: Development of EU KLEMS Database (24 months)


  • Integration of data from WP1-4 and WP8 into a database that can be used to calculate related measures of output, inputs and productivity.
  • Make database available for internal use by consortium, European Commission and restricted number of third parties between months 15 and 24, from month 24 database is public.

    Description of work
    Development of a system where meta-data describing the underlying data sources and the relationships between the various classification schemes (industries, labour input categories, asset-types) and between the economic concepts (output, intermediate inputs, factor inputs, PPPs) are separated from the statistical routines and growth accounting algorithms used to manipulate the data.

    Development of methods to treat confidential and proprietary data separate from public data, and to distinguish between statistical and analytical module of the database.

    Application of database software using SQL – Structured Query Language.

    Develop methods for integration of results with KLEMS databases outside EU, including U.S., Canada and Japan.

    Development of internal and external access to EU KLEMS Productivity Database.
