Though scientists and environmentalists have long expressed concern over the rapid deterioration of the global environment, economists have largely failed to recognize the issue's relevance to their field. Salah El Serafy argues for an increased focus on the economic aspects of environmental degradation, calling for a fundamental shift in how economists measure and discuss national income. Through a combination of new material reflecting recent developments in the field and previously published essays that provide a history of green accounting, the author emphasizes the importance of considering natural resources as part of a nation's economic capital. Setting forth what has become known as the 'El Serafy Method', this fascinating and complex volume presents both the justification and the methodology for giving the environment a place in the global economic conversation. Students, professors, researchers and policymakers in the field of environmental and ecological economics will no doubt find much to appreciate in this thoughtful and comprehensive analysis of the intersection between economics and the environment.
