This new edition of The Economics of Business Enterprise provides a comprehensive survey of the theory of the firm from the perspective of New Institutional Economics. It continues to emphasise the role of the entrepreneur within the firm and the emergence of institutional responses to rent seeking. Neoclassical, Transactions Cost, Austrian, Public Choice and Property Rights perspectives are contrasted and used to analyse private governance arrangements, contemporary developments in organisational form such as ‘the sharing economy’ and the regulatory framework.
