Introduction
This chapter introduces the book by presenting the case for institutional change. It starts by explaining what institutions are and subsequently argues how RTI is a valid case of institutional change. It poses the core research puzzle and the guiding research questions. It engages with the existing alternate scholarly explanations, point to the gaps, and suggests an alternate explanation. It proposes an endogenous model of institutional change that builds on gradual and incremental ideational shifts over time to finally reach a ‘tipping point’. In this chapter the entire book plan is laid out by indicating that this volume, spread over six chapters, deals with two distinct yet interrelated layers of the ideational and policy moves within the state apparatus and related institutions. The socio-political processes within both state and society and the role of global norms are part of these phases/layers.
