The laws that legislatures adopt provide the most important and definitive opportunity elected politicians have to define public policy. But the ways politicians use laws to shape policy varies considerably across polities. In some cases, legislatures adopt detailed and specific laws in efforts to micromanage policy-making processes. In others, they adopt general and vague laws that leave the executive and bureaucrats substantial autonomy to fill in the policy details. What explains these differences across political systems, and how do they matter? The authors address this issue by developing and testing a comparative theory of how laws shape bureaucratic autonomy. Drawing on a range of evidence from advanced parliamentary democracies and the American states, they argue that particular institutional forms have a systematic and predictable effect on how politicians use laws to shape the policy making process.

Building on a deep theoretical foundation and drawing on numerous examples, we examine how policies spread across the American states. We argue that for good policies to spread while bad policies are pushed aside, states must learn from one another. The three ingredients for this positive outcome are observable experiments, time to learn, and favorable incentives and expertise among policymakers. Although these ingredients are sometimes plentiful, we also note causes for concern, such as when policies are complex or incompatible with current practices, when policymakers give in to underlying political biases, or when political institutions lack the capacity for cultivating expertise. Under such conditions, states may rely on competition, imitation, and coercion, rather than learning, which can allow bad policies, rather than good ones, to spread. We conclude with lessons for reformers and policymakers and an assessment of our overall argument based on state responses to the COVID-19 pandemic.
