Rescaling the State provides a theoretically-informed and empirically-rich account of the processes of devolution undertaken in the UK since 1997, focusing in particular on the devolution of economic governance. Using case studies from England, Scotland, Northern Ireland and Wales, the book examines the purported reasons for, and unintended consequences of, the UK’s asymmetrical devolution settlement. As well as comparing policy and practice across the four devolved territories, the book also explores instances of good practice associated with devolution. The book advances our knowledge and understanding of devolution on both a theoretical and empirical front, and develops the novel concept of ‘filling in’ to advance our understandings of the particularities of the devolution settlement in each of the four territories, as new configurations of state-society relationships have emerged.
