Infrastructure only tends to be noticed when it is absent, declining, or decrepit, or when enormous cost overruns, time delays, or citizen protests make the headlines. If infrastructure is indeed a fundamental driver of economic growth and social development, why is it so difficult to get right?In addressing this perennial question, this volume-the fourth edition in an annual series tackling different aspects of governance around the world-makes the case for a governance perspective on infrastructure. This implies moving beyond rational economic analysis of what should be done towards an analysis of the political, institutional, and societal mechanisms that shape decision-making about infrastructure investment, planning, and implementation. Engaging with theories from sociology, political science, and public administration, and drawing on empirical analyses bridging OECD and non-OECD countries, the contributions to this volume dissect the logics of infrastructure governance in a novel way, providing timely analyses that will enrich both scholarly and policy debates about how to get infrastructure governance right.
