This book surveys the main rules of Company Law governing the making of contracts with companies. It adopts an economic perspective, examining these rules in terms of the risks they apportion between companies and parties contracting with them. It reviews the use that has been made of economics in the analysis of Company Law and considers what guidance this can provide in analysing corporate contracting. The book then examines the relevant law and the issues raised by this law, covering the role of corporate constitutions as the source of the authority of corporate agents, the mechanisms of corporate activity and decision-making, the identification of corporate contracting parties, pre-incorporation contracts and other contracts with non-existent companies, the contractual power of a company's board, the protection of parties dealing with subordinate corporate agents and the regulation of contracts in which a director has a conflict of interest.
