The United States of America (USA) have by far the highest negative trade balance among the world countries in absolute terms. At the same time they have continuously reduced the tariffs imposed on imports over the last decades (average import tarriff rate has gradually fallen from about 20% in the 1930’s to less than 2% currently). Please, provide your comment on this situation! Would you suggest the USA to impose more trade barriers in order to reduce their trade deficit – why or why not?
