Regardless of definition, transnationals share the same two advantages with multinationals: the ability to capitalize on differences in production costs and access to bigger markets. Generally, transnationals originate in countries with a higher per capita GDP, which makes labor more expensive. By expanding to countries with lower per capita GDP, the corporation can gain access to workers who require a lower wage. The transnational can also establish its R&D, marketing and management divisions in countries which have a higher concentration of workers suited for those types of tasks, optimizing overall efficiency. Also, some nations have trade barriers that limit the amount of foreign-produced goods sold within the country. By locating some production capabilities within key countries, a transnational can avoid these limits and increase foreign sales.
