Policy Reversal and Changing Politics: State Governments and Dam Removals

Abstract

Does the type of policy being considered determine the politics surrounding it? In this article, I examine how policy reversals may produce different politics than initial policy adoptions in the context of state river management policy. Traditionally, dam building was the dominant management policy, but in recent decades, efforts to restore rivers to their natural conditions through the removal of dams have become more prominent. I find that the patterns of state policymaking for policy reversals are generally similar to those that have been documented for policy adoptions, but with some important differences. Diffusion of reversals involves more states outside of active regions than is seen typically with policy adoption, and reversal diffusion occurs more gradually than adoption diffusion with many policy innovations. Finally, the most important determinants of these state policy reversals are a state's fiscal health and the presence of relevant interest groups.
