As Judge Calabresi has argued, preemption decisions are, at their core, a choice about which tier of government should have policy-making authority. In prior work, Mark Seidenfeld and I argued that the choice of whether or not to preempt state law decisions should be based explicitly on "fiscal federalism" considerations. The economic discipline of fiscal federalism attempts to measure the welfare effects of situating a given policy either locally, nationally, or somewhere in between.
