Elgar Research Agendas outline the future of research in a given area. Leading scholars are given the space to explore their subject in provocative ways, and map out the potential directions of travel. They are relevant but also visionary. This Research Agenda considers the future direction of research in tax law, channeling creative thinking from leading tax scholars around the world who explore potential routes for further development in both traditional and more unconventional areas of tax law. Showcasing visionary and provocative thoughts from leading international tax scholars, each chapter follows a clear methodological structure, setting each specific topic in context before identifying research gaps indicating potential avenues for future research. These developments are discussed in relation to tax law's interaction with a myriad of cutting-edge topics such as environmental challenges, new technologies, racial and immigration issues. The expert authors astutely draw out the social implications of tax law in order to present a case for developing a more global and interconnected approach to contemporary research ventures. A Research Agenda for Tax Law will provide guidance and inspiration for future researchers, doctoral students and scholars in the field of tax law and fiscal policy who wish to dive into some deeper, and perhaps unknown, waters of taxation.
