Clive George explained that the World Bank assessment of welfare gains
was based on full liberalization while the assessment done by the

Thomas Ruddy asked again about the differences and form of interplay

Colin Kirkpatrick replied that he had taken the Commission-wide IA into

journal entitled "Impact Assessment and Project Appraisal", the
September 06 issue of which will be on the SIA process.
