This up-to-date and informative book provides a comprehensive treatment of the costs of trading across borders and of trade facilitation policies. While traditional tariff and non-tariff barriers to trade have been reduced, international trade continues to involve higher costs in money and time than domestic trade. These include not only transport costs, that are determined by distance and commodity characteristics, but also at-the-border and behind-the-border costs which can be reduced by appropriate policies. Research on trade costs has flourished since the turn of the century, and this book by Patricia Sourdin and Richard Pomfret, takes stock of our increased knowledge of the nature and magnitude of trade costs, analyzing why they are high and how they can be reduced to increase the gains from trade. will appeal to economists and policy makers at the national level and in multinational institutions, researchers and postgraduate students interested in international trade and trade policy, as well as students in international business.
