The main benefit of trade facilitation is that it enables countries to specialize in the areas in which they are most capable. As Ralph Ossa showed in a working paper for the US National Bureau of Economic Research, if Germany did not have access to international markets, its standard of living would be half of what it is now.
贸易促进的主要好处是使各国专注发展自己最为擅长的领域。正如拉尔夫·奥萨向美国国家经济研究局提交的工作报告所显示的那样，如果德国没有利用国际市场，其生活水平可能只有现在的一半左右。德国经济研究所的Gabriel Felbermayr表示跨大西洋贸易和投资伙伴关系可以让德国生活水平提高3-5%。
