This paper studies the effects of trade policy uncertainty on the extensive and the intensive margins of trade for a sample of 149 exporters at the HS6 digit level. It measures trade policy uncertainty as the gap between binding tariff commitments under trade agreements (multilateral and regional agreements) and applied tariffs- what is also known as tariffs’ water. The results show that trade policy uncertainty is an important barrier to export. On average the elimination of water increases the probability of exporting by 12 percent. A one percent decrease of water also increases export volumes by one percent. Also, the negative impact of trade policy uncertainty is higher for countries with low quality of institutions and in the presence of global value chains. Finally, the findings show that on average trade policy uncertainty is equivalent to a level of tariffs between 1.7 and 8.7 percentage points.
