Incidents in the semi-public sector regularly reveal the underlying problems of managerial mania and decline. Since the Parliamentary Committee of Inquiry into Housing Associations and the new Housing Act, there have been fewer incidents involving managerial hubris and risky projects. However, in the event of incidents, the share of administrative decline of often long-serving directors of small corporations in particular is still considerable. The question in this article is what forms of managerial mania and decline occur among corporation directors and what internal and external supervisors can do to identify and mitigate this in a timely manner. To answer that question, this article examines the theory and practice of managerial mania and decline. Case analysis shows which manifestations of managerial mania and decline there were in the housing association sector. Internal and external supervisors can counter managerial mania and decline by exchanging knowledge with each other about the weak signals of decline and effective forms of countervailing power.
