The proliferation of open banking and open finance regimes across the globe demonstrates an ever-increasing interest of policymakers in empowering customers to take control of their data through innovative data sharing frameworks. These frameworks mostly operate within a single (e.g., financial services) sector but are poised to extend to other parts of the economy in the future - and eventually apply economy-wide.This book articulates the concept of economy-wide customer data sharing (CDS) frameworks, analyses in detail the main challenges associated with the development of such frameworks and is informed by the lessons learned from Australia's world-first cross-sectoral Consumer Data Right regime. It develops a first comprehensive taxonomy of CDS frameworks and offers valuable insights on crucial issues of customer trust, information security, consumer protection and participant regulation.This study, apart from its scholarly importance, has clear practical value. It formulates twelve lessons that will assist governmental officials and other policymakers engaged in establishing and revising data sharing frameworks across the globe. It is essential reading for anyone interested or involved in the law and policy related to the sharing of a most precious resource in the modern economy - customer data.
