Tariff scheme choice

Review of World Economics - This paper examines the determinants of the probability that an exporter chooses between a most-favored nation (MFN) scheme and multiple regional trade agreement (RTA)...     

How does import processing time impact export patterns?

We examine how import processing time, which is one of the major obstacles in international trade, affects export patterns at the establishment level. Investigating the effect of such time costs on export patterns reveals how smoothness or sluggishness in operations at one stage affects all stages in an international production network. We first discuss the effects of import processing time on exports, export shipment frequency and exports per shipment from a theoretical standpoint. We employ highly detailed customs data for Thailand from 2007 to 2011 to empirically investigate our theoretical predictions. Import processing time is measured using the difference between the dates on which import shipments arrive in ports and when they were released from the container yard. Results suggest that longer import processing times reduce total exports, particularly as a result of decreasing export frequency; this testifies to the importance of time costs in international trade. It is also revealed that negative effects of import processing time on exports per shipment appear in some specific instances, such as in the case of sea transportation. These results imply that the time spent in one stage has significant effects on both upstream and downstream stages in international production networks.     

Impacts of common rules of origin on FTA utilization

This study empirically examines the impacts of sharing rules of origin (RoOs) with other ASEAN?+?1 free trade agreements (FTAs) on ASEAN–Korea FTA/ASEAN–China FTA utilization in Thai exports in 2011. Our detailed empirical analysis suggests that the harmonization of RoOs across FTAs plays some role in terms of reducing the costs yielded through the spaghetti bowl phenomenon. In particular, the harmonization to “change-in-tariff classification (CTC) or regional value content (RVC)” will play a relatively positive role in not seriously discouraging firms’ use of multiple FTA schemes. In contrast, harmonization to “CTC” or “CTC and RVC” hinders firms from using those schemes.     

Measuring the usage of preferential tariffs in the world

The preference utilization ratio, i.e., the share of preferential imports out of total imports, has been a popular indicator for measuring the usage of preferential tariffs vis-à-vis tariffs on a most-favored-nation basis. A crucial shortcoming of this measure is the data requirements, particularly for data on imports classified by tariff schemes, which are not available in most countries. This study proposes another measure for preference utilization, termed the “tariff exemption ratio.” This measure is a good proxy for the value of offered preferences by each importing country to the rest of the world. Importantly, it can be computed by employing only publicly available data, such as those provided by the World Development Indicators, for its computations. We can thus calculate this measure for many countries for an international comparison. Our finding is that tariff exemption ratios differ widely across countries.
