Ha-Joon Chang evaluates the role of the state in economics and development. In this collection of essays, he reviews theories and practices of state intervention as they have developed over two centuries of modern capitalism. He develops an institutionalist approach to the role of the state in economic change, and examines the issues involved in particular settings including industrial policy, trade policy, intellectual property rights, regulation, and strategies towards transnational corporations. He mounts a sophisticated theoretical and historical case for the continuing essential and constructive roles which the state can and must play in economic development.
