This book advances existing work on pockets of effectiveness (PoEs) by systematically investigating the link between political context and bureaucratic performance, by presenting a new theoretical framework in conjunction with a comparative research design, and by linking PoEs research to broader debates about the politics of state-building. Based on a critical assessment of the book’s contributions and limitations, this commentary suggests some future directions for PoEs research. It first discusses the reframing of PoEs suggested by the authors, their power domains framework, the distinction between PoEs emergence and persistence, the role of ideas for PoEs, and the generalizability of the book’s findings. Future directions for PoEs research are then discussed, covering theoretical framework and methodology, and suggesting a move from a PoEs focus to a broader perspective on ‘topographies of state performance’ into which the study of PoEs can be embedded.
