International Economics (Routledge Revivals) [PDF ebook] 

Most of the existing textbooks on international economics – a widely taught and ighly popular subject – are long and too detailed and advanced for many students. This book, first published in 1983, and written by a respected leading authority, presents the essentials of the topic in a simple and straightforward way. The book contains the minimum of algebra and avoids detailed proofs. It incorporates the most recent theoretical advances and discusses current issues in comercial policy. Moreover, it puts less emphasis than other textbooks on trade theory and more on balance of payments theory and on questions of international finance and international finance anf international monetarism which are the areas of current concern.
