This book examines in detail the process of change in 240 city, county and state public bureaucracies responsible for local finance administration. Using the longitudinal method of analysis, the data show organizational structures to be much less stable than conventional stereotypes have suggested. Variables such as organizational leadership, claims to domain, and survival (as opposed to replacement or reorganization) were found to mediate environmental effects on bureaucracies. The book also discusses traditional theories of bureaucracy, theories emphasizing the importance of environment for organizational theory is possible. The concluding chapter draws extensive theoretical implications from the empirical findings of the study.
