Understanding Contract Law provides an accessible, in-depth analysis of the purpose of contracting and the role of the law of contract, as well as theories that inform it. Assessing the historical development of this cornerstone of law, the book provides detailed analysis of some of the leading theoretical explanations, and how they are applied in jurisdictions throughout the world. With a new chapter examining the impact of globalization on contract law, this new edition also includes recent behavioural research around responses to contract breach. The book's accessibility is enhanced by text boxes defining key concepts and terms, and biographical notes of leading figures and scholars. This ensures that readers are able to gain a clear understanding of the narratives and theories explained in the book, and to appreciate how contract law has evolved. Uniquely, the book is not limited to one jurisdiction, making this an essential text for students wishing to expand their knowledge of this fundamental area of law around the world.
