Book excerpt: This edited volume covers the challenges currently faced by consumer law in Europe and the United States, ranging from fundamental theoretical questions, such as what goals consumer law should pursue, to practical questions raised by disclosure requirements, the General Data Protection Regulation and technology advancements. With governments around the world enacting powerful new regulations concerning consumers, consumer law has become an important topic in the economic analysis of law. Intended to protect consumers, these regulations typically seek to do so by giving them tools to make better decisions, or by limiting the consequences of their bad decisions. Legal scholars are divided, however, regarding the efficacy and effects of these regulations; some call for certain policies to be abolished, while others support a regulatory expansion.
