OECD – See Organization for European Economic Cooperation (OEEC).
The OECD’s main tasks are the discussion of problem areas and the analysis of economic data such as productivity flows of goods or capital. Based on the results, the OECD then makes “policy recommendations” to promote the free movement of goods and capital.
These results and recommendations are not legally binding on individual countries.
