This book is the first full-length treatment of the desirability and feasibility of implementing a citizen's income (also known as a basic income). It tests for two different kinds of financial feasibility as well as for psychological, behavioral, administrative, and political viability, and then assesses how a citizen's income might find its way through the policy process from proposal to implementation. Drawing on a wide variety of sources of evidence from around the world, this new book from the director of the Citizen's Income Trust, UK, provides an essential foundation for policy and implementation debates. Governments, think tanks, economists, and public servants will find this thorough encompassing book indispensable to their consideration of the economic and social advantages and practicalities of a basic income.
