Abstract

Tariffs impede trade. They are the most visible instrument for protecting domestic companies against foreign competition. So-called non-tariff barriers to trade (NTBs) are less visible. NTBs include restricting import quantities, registration formalities for imports or state aid for domestic suppliers. Our study shows that NTBs implemented worldwide between 2010 and 2015 have been responsible for roughly 16 percent of missing global trade in 2015, amounting to about USD 512 billion. German exports could have been at least USD 43 billion higher in 2015 if these NTBs had not existed. The value of German imports in 2015 would have been at least USD 34 billion higher than the actual volume of imports.
