The role of policy design in policy continuation and ratcheting-up of policy ambition

Effectively addressing grand societal challenges like climate change and environmental degradation requires policy intervention that is not only continuous but also increasing in ambition over time. However, negative feedback could lead to policies being weakened or even discontinued after a while. An important but unresolved policy question, therefore, is whether policies can be deliberately designed to survive (i.e., to “stick”) and, ideally, be replaced with more ambitious ones over time (i.e., to “ratchet up”). We bridge policy feedback and policy design scholarship to derive hypotheses on the effects of two policy design features-“intensity” (i.e., a measure of policies' overall design) and “specificity” (i.e., a measure of policies' targeted focus)-on policy (dis-)continuation and ratcheting-up (-down) of ambition. Focusing on policy design, we contribute to the theorization and empirical understanding of endogenous factors behind policy change. We test our hypotheses with an event history dataset of 627 low-carbon energy policies in eight developed countries. Conducting a multilevel survival analysis, we find statistically significant evidence of more intense policies being replaced with less intense ones, i.e., more intense policies lead to ratcheting-down of ambition. We also find that more specific policies are more likely to be replaced with more intense policies, i.e., more specific policies lead to ratcheting-up of ambition. Based on these novel insights, we discuss how policy design can navigate these complex dynamics. In this sense, our approach also contributes to the discussion about the “forward-looking” potential of the policy sciences.
