Laboratories of Power: Public Policy, Organized Interests, and Interdependence in American Federalism

State governments are now key policymakers in important areas including energy, education, labor, and criminal justice, so understanding the politics of public policy requires grappling with federalism as an institution. My book-style dissertation, Laboratories of Power: State Policy, Interest Groups, and Interdependence in American Federalism, amends and expands the classic logic of states as “laboratories of democracy.” The notion of laboratories of democracy proposes that successful state policy experiments diffuse across the federal system due primarily to mechanisms of learning and healthy competition. I argue that states can also act as laboratories of power. State-level reforms that benefit particular organized interests also strengthen them politically. These interests, in turn, often have an economic incentive to apply their newfound strength to seek to propagate reforms. Like learning and competition, the policy feed-in effects I study can drive policy diffusion—but the core mechanisms and central actors (organized interests) are different, with different implications for those seeking to change public policy over the long term.

In three policy areas, I demonstrate how mechanisms associated with laboratories of power drive processes of policy reform. First, in the case of rooftop solar policy, I show how solar power installers built their industry by first locating in states with favorable policy terrain, and then leveraged resources they accumulated to influence policy in other states, allowing them to expand into new markets. Turning to marijuana policy, the marijuana industry initially followed a similar pattern, but because of the context of a federal prohibition, industry political efforts soon focused much more heavily on influencing national policy than on spreading legalization state-by-state. I leverage exogenous variation in likelihood of legalization from ballot initiative rules (using instrumental variables analysis), and over-time variation in legalization (using difference-in-differences) to show that state legalization had a causal effect on support for marijuana policy reforms in Congress. Finally, in the case of charter school policy, I argue that as state-level experiments drove charter growth, charter advocates were able to recruit certain foundations—which saw charter schools as a vehicle for achieving their own education policy goals—as allies. Crucially, foundations used their extensive resources to promote pro-charter policies across the states and at the federal level—more broadly than charter school networks and other advocates would have been able to on their own.

By highlighting the national-level political implications of state-level policy decisions, the dissertation supports the notion that state politics and policy is more consequential than traditional perspectives on federalism suggest, and in doing so, helps to explain why national groups have made such massive investments in state politics in recent years. Indeed, findings suggest that state policy reforms can be a crucial ingredient in building coalitions for (geographically) broader policy change.
