Overview

With the conclusion of the Bali talks, trade ministers around the world will be seeking approval of the “Bali Package” in national forums. The Bali Package includes significant enhancements in trade facilitation. The impacts of trade facilitation can often be understood in two parts, direct and indirect impacts. Frequently, the indirect, time delay inducements of regulations, can have the most significant impact on a counties trade flows when compared to direct costs of trade and tariffs.

Direct customs costs and shipping costs are those which arise from the consumption of real resources in the movement of goods and are well represented by customs, shipping fees, and the costs of traders to manage the movement of goods.

Indirect costs (the subject of this database) are measured as importers willingness to pay to move goods faster, either by streamlining customs procedures, inspections or security requirements. The benefits of efficient (rapid) customs and shipping arise from manufactures need and willingness to pay to receive inputs in a timely manners (just in time delivery) and consumers’ willingness to pay for goods which have rapid market depreciation (e.g., smartphones, electronics, fresh fruit and flowers). Recent research has shown the indirect costs of customs procedures often exceed tariff barriers in many countries (Hummels et. al. 2007 see below).

Selected Literature

The following papers provide further information on the derivation of the value of time in trade and related applications in CGE modeling. We list, in many cases, official journal publications. However, we link to a free version, if available, which are often early working papers. Readers are encouraged to obtain official journal versions, where practical.
