It’s an institution—a phrase we have all come across or may have used. We intuitively understand what it means. There is something special, perhaps mythical, about them. We value these institutions. We may even find it hard to imagine a life without some of these institutions. In this chapter, we offer a definition of institutions and introduce our theoretical framework (based on the work of Philip Selznick). We introduce the case studies in this book and identify patterns of institution building.
