Unjust Enrichment and the Digital Economy

by Mark Hsiao

Abstract

This review examines Mark Hsiao’s contribution to the emerging literature on restitution in digitally mediated contexts. It highlights the book’s exploration of enrichment arising from electronic payments, data-driven value creation, and algorithmic systems. The reviewer evaluates the author’s success in integrating doctrinal analysis with technological insight, noting the book’s strengths in identifying conceptual tensions within unjust enrichment law. While acknowledging certain normative challenges, the review concludes that the book provides a timely and valuable framework for understanding how restitutionary principles may evolve in response to digital transformation.
