Despite the increased research interest in the economic effect of policy uncertainties, trade behavior during such times is still not fully understood. Using the trade gravity model, this study examines the effects of economic policy uncertainty on trade in 22 countries from 1997 to 2020, finding that both domestic and foreign policy uncertainties negatively and significantly affect bilateral trade, exports, and imports. Additionally, there are substantial variations in trade reactions to policy uncertainties across countries, with more export-sophisticated countries being resilient to domestic policy uncertainties and vulnerable to foreign policy uncertainties, while less export-sophisticated countries are doubly vulnerable to both types of uncertainties.
In spite of the recent surge of research interest on the economic effect of policy uncertainties, trade behaviour during times of policy uncertainties is still not fully understood. We use the trade gravity model to examine the effects of economic policy uncertainty (EPU) on the trade of 22 countries over the period 1997-2020, based on the argument that EPU inflates bilateral trade costs. Overall, our results indicate that bilateral trade, exports, and imports are all negatively and significantly affected by both domestic and foreign policy uncertainties. Moreover, we document substantial heterogeneous trade reactions to policy uncertainties across countries. Specifically, in more export-sophisticated countries, our results show that only foreign policy uncertainty has a significant and negative effect on trade; whereas in less export-sophisticated countries, trade is significantly and negatively affected by both domestic and foreign EPU. These findings point to the double vulnerability of less export-sophisticated countries to domestic and foreign policy uncertainties and, to the resiliency of more export-sophisticated countries to domestic policy uncertainties and to their vulnerability to foreign policy uncertainties.
