Bharat Hazari 
Routledge Revivals: International Trade (1986) [PDF ebook] 
Theoretical Issues

First published in 1986, this book examines international trade, offering different theories and considering contemporary developments. Professor Hazari connects these theories and developments, such as theories of comparative advantage and factor-price differentials, to economic expansion and terms of international trade. Many key economic problems are related to the theory of international trade, problems such as tariffs, the dependency of developing countries and changing patterns of world trade, and the book shows how theory impinges on these other important issues. The theory of international trade is a popular and widely taught specialism within economics. This book surveys the pure theory which forms the core of the topic.
