Across the globe, governments are developing policies that increase transparency and accountability in politics. A key initiative of this is the regulation of lobbying. Building on the landmark first edition, Regulating lobbying updates its examination of all jurisdictions with lobbying regulations, from the Americas to Europe, Middle East, Asia and Australia. It provides unique insights into how the regulations compare and contrast with one another, and offers an up-to-date theoretical classification of different regulatory environments. The book comprehensively examines jurisdictions worldwide and investigates whether some measurements of the robustness of lobbying laws are more valid and reliable than others. This second edition covers more countries than its predecessor, and draws on the authors' experience of advising governments in order to provide a no-nonsense guide on how to make or amend a lobbying law. This book will appeal to an academic readership, to those teaching courses on lobbying and regulatory politics and to those researching in the field. It will also be of great interest to practitioners, including legislators, civil servants and lobbyists themselves.
