Increasing number of countries has enacted competition laws over the past 20years. In preparing their own laws, these countries, most of which aredeveloping countries, benefit from the experiences of countries and communitiessuch as United States and the European Union. The other source that thecountries take into account in issuing or changing competition laws is the modelcompetition laws, prepared by the international organizations like UNCTAD.UNCTAD Model Law has been prepared in a flexible structure, by taking intoconsideration of the experiences of the developed and developing countries.Countries, who wish to benefit from the Model Law, have the possibility to use itby making the changes as they wish. Articles with regard to objective, scope, definitions, restrictive agreements,abuse of dominant position, mergers and acquisitions reflect the generalapproach of the Model law on the protection of competition. Taking intoconsideration developed countries’ legislations, such as the US’s and EU’s,which serve as a source to many countries’ competition laws, as well as theTurkish and other developing countries’ competition regulations, would help tounderstand the general approach of the Model law on the protection ofcompetition. Adoption or the use Model law by the member countries during the law=makingprocess, will make member countries legislations closer. Member countries,which own close competition legislations, would easily bring the positionscloser to each other during the negotiations in international arena andultimately may easily compromise on an international competition agreement.
