                    Data Policy Issues
• Prerelease policy in presence of multiple
  prereleases
• Pricing of version 5
• Distribution of old versions of GTAP data
• Future directions: open-sourcing of the
  GTAP data base


April 12-14, 2000        Advisory Board Meeting   2
              Prerelease of version 5
• Initial prerelease will be rough
• Plan several updates to bring in new
  information on:
      – bilateral trade in services and margins
      – improved protection data
      – updates to key IO tables
• Very important to keep prerelease in-
  house

 Distribution of Old GTAP Data
• Distribution of old versions free if either:
      – two releases old, or
      – five years since public release
• What about version 4?
      – we will offer discounted versions of
        GTAPagg at the conference in June
      – thereafter for others

       Open-sourcing: Motivation
• Tension between proprietary database
  and need for replication
• Addition of special modules more
  efficient with source-code
• Sustainability of the project
• Natural evolution from cottage industry
  to manufacturer to service industry

April 12-14, 2000   Advisory Board Meeting   6
        Open-sourcing: Feasibility
• Data base is organic whole -- modules
  cannot be fully independent
• Need for common skill-set
• Web-based dissemination
• Short courses to train database contributors
• GTAP advisory board guides project
• Technical input from group of power users

April 12-14, 2000   Advisory Board Meeting   7
          Open-sourcing: Viability
• Data base sales have become important
  source of revenue
• Revenue replacement:
      – additional consortium members
      – database course revenues
      – special projects
• Adjust length of time to public release in
  order to create necessary incentives for
  continued consortium membership
April 12-14, 2000   Advisory Board Meeting     8
        Open-sourcing: Next steps
• Prepare NSF proposal: deadline is
  August 1
• Input from Advisory Board needed
