                The Importance of Facilitating Imports for International
                Trade Flows: Evidence from the Auto Industry

                       mports are becoming more important than ever in world trade in the face of rapid globalization and the
                       spread of global supply chains. One way to boost imports is through e cient regulations and practices.
                       While the impact of regulatory restrictions is well established for exports, their e ect on imports has
                been studied to a lesser extent across countries. is Brief aims to help ll that gap. Focusing on the auto
                industry, it analyzes the relationship between e cient import procedures and international trade ows in
                190 economies. An analysis of the data at the global level suggests that economies where importing auto parts
                is relatively fast and inexpensive tend to have not only higher imports of auto parts (in terms of volume and
                value) and a higher ratio of imports of auto parts to total GDP, but also a higher ratio of imports of overall
                manufactured products to total GDP. Similarly, economies with e cient procedures when importing auto
                parts tend to have a greater share of automobile exports of total GDP. e Brief does not provide a causal
                interpretation and more analysis will be needed to understand the direction of the relationships. But given
                the strong positive association between the e ciency of import procedures and international trade,
                streamlining import regulations appears to be an important aspect for policy makers to focus on in
                formulating trade policy.

                are no less important. As David Ricardo noted centuries ago in                        Why Are Efficient Import Regulations and

Note: The sample includes 180 observations for panel a and 135 observations for panel b. The figures use country codes from Doing Business.
Further regressions for panel a and panel b highlight that the relationships are significant at the 1 percent level and remain significant after controlling for
income level, population, and tariff rates for HS8708 (auto parts and other vehicle parts). A further check on robustness added controls on natural resource
endowment and share of value added of manufacturing sector of total GDP; the results remain significant at the 1 percent level. After adding the respective
controls, the sample reduces to 106 observations for both panels. Data for the following are from the World Development Indicators database (2018): (1)
gross national income (GNI) per capita, a proxy for income level; (2) exports of fuel as a share of merchandize exports (2018), a proxy of natural resources
endowment; (3) value added of manufacturing sector as a share of GDP (2018); and (4) on population size (2018). As a proxy for tariff levels, data on the
tariff level from the HS of Tariffs for HS 8708 (auto parts and other vehicle parts) are taken from ITC Trade Maps from 2018.

A futher regression highlights that the relationship is significant at the 1 percent level and remains significant after controlling for income level, population,
and tariff rates for HS8708 (auto parts and other vehicle parts). A further check on robustness added controls on natural resource endowment and share of
value added of manufacturing sector of total GDP; the results remain significant at the 1 percent level. After adding the respective controls, the sample
reduces to 106 observations.
