Influences on Intergovernmental Implementation: The States and the Superfund

What factors influence the successful implementation of intergovernmental policy? Many scholars have noted the influence of state-level factors on the implementation of such policies. However, much of the research on the United States Environmental Protection Agency's Superfund program has focused only on national-level factors. This study addresses this discrepancy in the literature. State Superfund implementation from 1987 to 1994 is examined using Goggin et al.'s (1990) Communications Model. Pooled cross-sectional time-series analysis with an event-count model is employed to capture the comparative and longitudinal nature of state implementation. The results suggest the importance of state-level factors in Superfund implementation.
