Trade facilitation has come to be widely recognized as an important part of regional and multilateral efforts at promoting trade integration.

By identifying and promoting aspects of trade facilitation policies with particular impacts on fixed costs, developing country policymakers can make concrete progress towards the long-held goal of export diversification.
