Chapter 2 develops the analytical framework employed in the six country cases in this volume, highlighting the importance of state capacity—captured by the concept of state infrastructural power—and political competition. In doing so, the discussion confronts important debates in the politics of development and political science that have relevance well beyond social protection. The first of these debates concerns the relative importance of historical legacies and contemporary political dynamics for explaining state performance and service delivery. The second debate concerns the relevant unit of analysis in political research. In contrast to the considerable degree of ‘methodological nationalism’ in much research in comparative politics and the politics of development, this study contributes to a growing literature that examines sub-national political processes.
