Proposing innovative ideas on the links between taxation, citizenship and democracy, this multidisciplinary book contributes to ongoing research and scholarship by emphasizing the importance of taxation to the functioning of modern democracy. This book provides methodological and theoretical research tools from various disciplines such as law, economics and sociology. It considers, among other research questions, the disciplinary boundaries surrounding taxation, citizenship and democracy; the taxation of migrants in an era of globalization; and the role of procedural safeguards in legitimizing the use of automated risk management systems. Featuring contemporary case studies from the perspectives of taxpayers, legislators and tax administrations, it presents new perspectives on capital migration, social security and noncitizen farmworkers, as well as cooperative compliance policies in Nordic countries. Examining the tax systems of a number of countries across the globe, this book is an essential resource for scholars of constitutional and administrative law, economics of social policy, inequality, tax law and fiscal policy, and welfare states. It will also be a helpful resource for students in these disciplines.
