Anderson showed that if developing countries cut their tariffs by the same proportion as high-income countries, and services and investment were also liberalized, the annual global gains could climb to $120 billion, with $17 billion going to the world's poorest countries by 2015.
Anderson的研究显示如果发展中国家降低关税的幅度和高收入国家相当，并同时让服务和投资自由化，那么到2015年全球的年收益将会达到1200亿美金，而其中的170亿美金将会流向世界上最贫穷的国家。
