Book excerpt: This title was first published in 2000: In examining the domestic politics of international co-operation, this book addresses two important questions: 1. Why do governments often take different positions in negotiations about common problems - why do some states push for international regulation while others hold back? 2. How can variance in the domestic implementation of and compliance with, international agreements be explained - why do some states deliver more than they have promised, others less? The authors report findings and observations from a major study which focused on efforts to establish international regulations to cope with the problem known as acid rain. They provide in-depth case studies of nine European countries as well as a comparative analysis searching for patterns and general conclusions.
