The Regulation of Social Media Influencers
(Edward Elgar Publishing, Technology and Society Series 2020)
In today’s society, the power of someone’s reputation, or influence, has been turned into a job: that of being a social media influencer. This role comes with promises, such as aspirational work, but is rife with challenges, given the controversy that often surrounds influencers. This is the first book on the regulation of social media influencers, that brings together legal, economic and ethical angles to further unveil the implications of influencer marketing.
Thus far, influencers have been under scrutiny for not disclosing paid advertising, yet their activity has many more questionable implications. This edited volume combines insights from law, economics, ethics and communication science to reveal these implications and propose new ways in which public bodies, social media companies and citizens ought to relate to influencer marketing.

Time, Law, Change (edited with Yaniv Roznai)
(Hart Publishing, 2020)
Offering a unique perspective of an overlooked subject, the relationship between time, change, and lawmaking, this edited collection brings together world-leading experts to consider how time considerations and social, political, and technological change affect the legislative process, the interpretation of laws, and the definition of the powers of the executive and the ability of legal orders to promote innovation.
Divided into four parts, each part considers a different form of interaction between time and lawmaking. The first part offers both legal, theoretical, and historical perspectives on the influence of time and change on legal interpretation, legislative quality, and constitutional resilience. The second part offers the reader an analysis of the phenomenon of inter-temporality in the constitutional process as well as a theoretical and empirical reflection upon the meaning of the principle of legal certainty and legitimate expectations. The third part of the book analyses how specific times shape the law. By 'specific times' the editors wish to refer to situations that put the rule of law or citizens' protection at stake in different ways. The fourth part addresses the complex relationship between technological change and lawmaking.

The Judge and the Proportionate Use of Discretion: A Comparative Administrative Law Study (edited with Boudewijn de Waard)
(Routledge Publishing, 2015)
This book examines different legal systems and analyses how the judge in each of them performs a meaningful review of the proportional use of discretionary powers by public bodies. Although the proportionality test is not equally deep-rooted in the literature and case-law of France, Germany, the Netherlands and the United Kingdom, this principle has assumed an increasing importance partly due to the influence of the European Court of Justice and European Court of Human Rights. In the United States, different standards of judicial review are applied to review ‘arbitrary and capricious’ agency discretion. However, do US judges achieve a similar result to the proportionality or reasonableness test? Drawing together a selection of key experts in the field, this book analyses the principle of proportionality in the judicial review of administrative decisions from different perspectives.

Constitutional Sunsets and Experimental Legislation: A Comparative Perspective
(Edward Elgar Publishing, 2014)
This innovative book explores the nature and function of ‘sunset clauses’ and experimental legislation, or temporary legislation that expires after a determined period of time, allowing legislators to test out new rules and regulations within a set time frame and on a small-scale basis. Sofia Ranchordás presents a thorough analysis of sunset clauses and experimental legislation from a comparative perspective, and offers a clear legal framework for their implementation.
