Alistair Ulph has made a major contribution to the literature on trade-environment issues. This impressive book gathers together a selection of his most influential papers covering the last eight years, paying special attention to strategic environmental policy and its implications. The book addresses the often expressed concern that globalization and trade may have a detrimental effect on the environment. Drawing on the tools of modern trade theory, Alistair Ulph argues that even if governments seek to use their environmental policies to secure strategic trade advantages, this need not imply they will necessarily set too weak environmental policies and regulations. The extent to which governments set these environmental policies to secure competitive trade advantage is also examined. Environmental and trade economists, policy advisors to national governments and international trade and environment agencies, will find this book of immense value in understanding the links between trade and environment policies.
