Question 3/3

1. Motivation
   With the recognition of the importance of aligning the basic components of tariffs for international accounting purposes based on costs and on common costing methodologies, Study Group 3 should continue to carry out studies on a regional basis for the development of cost models.
   In view of different environments in various regions, studies under Questions 1/3 and 2/3 on a global basis should be supplemented by studies on the regional aspects of the issues concerned.
   The regional Tariff Groups can make input into Study Group 3 of their findings.



2. Question
   Regional studies for the development and application of cost models together with related economic and policy issues.



3. Tasks
   The studies are to be carried out on a regional basis by the regional groups set up within Study Group 3 to deal with international tariff and accounting principles, namely:
   • Regional Tariff Group for Africa (TAF)
   • Regional Tariff Group for Latin America and the Caribbean (TAL)
   • Regional Tariff Group for Asia and Oceania (TAS)
   • Regional Tariff Group for Europe and Mediterranean Basin (TEUREM)
   
   Results of the studies should be developed in the form of new or revised D.300R to D.600R series Recommendations, as well as regional inputs (reports and liaison statements) to the studies of Questions 1/3 and 2/3, as appropriate. In studying this Question, special explicit consideration should be given to the needs of developing countries.
