Abstract: | ABSTRACT How do public agencies respond when reform proposals threaten downsizing, reduction in functions, or termination? Agency survival during administrative reform is conventionally explained by structural characteristics, informed by the hardwiring thesis derived from the politics of the U.S. federal government. Parliamentary systems provide greater opportunity for agency reform, but there is little evidence of how agencies respond to such proposals or how proposals are altered prior to decision. We consider agencies as active participants in the reform processes, using strategic-relational theory to analyse their strategizing. The article employs detailed empirical evidence on 12 agencies subject to reform by the UK government between 2010 and 2013. We identify three archetypical defence strategies—technical expert, network node, and marginal adaptor—and argue that coding agency strategies alongside structural analysis can help better explain reform outcomes. |
