For almost three decades, the European Union (EU) has adopted measures to regulate consumer transactions within the internal market created by the EU Treaties. Existing legislation is largely based on directives harmonizing aspects of national consumer laws. This Brief argues that a more appropriate approach for EU consumer law would be legislation in the form of a regulation which is applicable to cross-border transactions only. The author considers the constitutional constraints of the EU Treaties, before examining the case for a cross-border-only measure. He argues that the cross-border approach is preferable, because it would provide clearer benefits for consumers seeking to buy goods and services across borders, while not upsetting domestic law unnecessarily—in particular in the context of e-commerce, with implications for industry, policymaking, and regional development. The Brief concludes by suggesting that a successful EU measure on cross-border consumer transactions could create a template for global initiatives for transnational consumer law.

Big Data collected by customer-facing organisations – such as smartphone logs, store loyalty card transactions, smart travel tickets, social media posts, or smart energy meter readings – account for most of the data collected about citizens today. As a result, they are transforming the practice of social science. Consumer Big Data are distinct from conventional social science data not only in their volume, variety and velocity, but also in terms of their provenance and fitness for ever more research purposes. The contributors to this book, all from the Consumer Data Research Centre, provide a first consolidated statement of the enormous potential of consumer data research in the academic, commercial and government sectors – and a timely appraisal of the ways in which consumer data challenge scientific orthodoxies. Praise for Consumer Data Research 'An insightful, state-of-the-art guide into the social and commercial value of applying geographical thinking to the study of consumer data.' Professor Richard Harris, University of Bristol 'An excellent guide to leveraging the value of academic research on valid data. Partnerships based around consumer data should be encouraged and supported by all and their outputs used to better the way we manage the world we live in.' Bill Grimsey, retailer and author of The Vanishing Highstreet 'The use of data from everyday consumer transactions is a potential game-changer for understanding economic and social patterns and trends. This is an excellent overview of the field.' Dr.Tom Smith, Managing Director, Office for National Statistics Data Science Campus

The product of a unique collaboration between academic scholars, legal practitioners, and technology experts, this Handbook is the first of its kind to analyze the ongoing evolution of smart contracts, based upon blockchain technology, from the perspective of existing legal frameworks - namely, contract law. The book's coverage ranges across many areas of smart contracts and electronic or digital platforms to illuminate the impact of new, and often disruptive, technologies on the law. With a mix of scholarly commentary and practical application, chapter authors provide expert insights on the core issues involving the use of smart contracts, concluding that smart contracts cannot supplant contract law and the courts, but leaving open the question of whether there is a need for specialized regulations to prevent abuse. This book should be read by anyone interested in the disruptive effect of new technologies on the law generally, and contract law in particular.

Consumer law, particularly consumer credit law, is characterised by increasingly complex regulation in Western economies. Reacting to the Global Financial Crisis, governments in the UK, the EU, Australia, New Zealand and the United States have adopted new laws dealing with consumer credit, responsible lending, consumer guarantees and unfair contracts. Drawing together authors from all of these jurisdictions, this book analyses and evaluates these initiatives, and makes predictions as to their likely success and possible flaws.
