The Single Windows electronic environment, introduced as part of the World Trade Organizatione DEGREES--s Agreement on Trade Facilitation (ATF) in December 2013, promises to bring meaningful gains to all parties involved in cross-border commerce. However, a common view in developing countries is that the systeme DEGREES--s implementation costs far outweigh its presumed (and questionable) benefits. Now, in this first book to critically examine the correlation between Single Windows and economic development, the author analyses key challenges facing the adoption of Single Windows and offers well-thought-out direction to developing countries preparing to enforce the relevant provisions of the ATF.
