"Local Exchange Trading Systems (LETS), the subject of the book, is a novel and interesting social phenomenon which seems to constitute a more ecologically rational and socially inclusive form of economic activity. LETS is a system for exchanging goods and services without the use of formal, legal tender. Unlike barter, LETS members buy and sell using their own nominal currency units, but the currency in which trade is conducted is purely a means of exchange, not a commodity in itself or a store of value." "The authors in this book examine LETS in detail, and in particular they discuss whether LETS can be viewed as an aspect of the 'greening' of citizenship, with the potential to contribute to the transition to, and maintenance of, a more sustainable society." "This book will be of interest to all social scientists interested in social movements, environment and citizenship, and in particular those wanting to understand the application of Q methodology for social science research."--Jacket.
