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. Academics and students of Law, Economics, Ethics and Communication Science will find policy making insights in this collection. In addition, The Regulation of Social Media Influencers will be essential reading for regulators. Contributors include: E. Apa, M. de Cock Bunning, S. de Jans, M. de Veirman, R. Ducato, I. Ebert, C.
