This book is novel in that it reveals significant issues of economics, management and business fields currently observed in network industries such as public utilities and transportation, and provides empirical evidence of their mechanisms and policy implications from various perspectives. This is a holistic collection of literature on public utilities economics and management, since the industries discussed include a wide range such as electricity, water supply, sewerage, transport, and postal service, which compound social infrastructure as public benefit service, and the issues examined contain not only economics topics such as cost, efficiency, and productivity, but also management topics such as governance, strategy and organizational restructuring. The book also investigates general private companies to derive future implications for policy and governance of public utilities, and covers multiple countries such as Japan, the US, and Vietnam. It demonstrates various empirical approaches and methodologies for public utility analysis through 17 chapters by experts in each field, which contributes to further cultivation of empirical studies in public utilities.
