Universal basic income is a controversial policy which is causing a stir amongst academics, politicians, journalists and policy-makers all over the world. The idea of receiving 'money for nothing', with no strings attached, has for a long time appeared a crazy or radical proposal. But today, this policy is being put into practice. With more and more trials and experiments taking place in different countries, this book provides both the theory and context for making sense of different basic income approaches, examining how the policy can be best implemented. Unlike many other texts written on this topic, the book provides a balanced account of basic income, weighing up the pros and cons from a number of different positions. The book provides a theory chapter, enabling readers to grasp some of the complex philosophical ideas and concepts which underpin universal basic income, such as social justice, equality and freedom. It also provides an examples chapter, which examines both historical and contemporary basic income studies to have taken place from around the globe. The book also features chapters on the environment and the work of women, as well as an 'against' universal basic income chapter, which specifically draws on the criticisms of the policy. This volume is an essential resource for anyone who wishes to get to grips with universal basic income.
