We present a model where heterogeneous districts choose both whether to experiment and the policies to experiment with. Since districts learn from each other, the first-best requires that policy experiments converge so that innovations are useful also for neighbors. However, the equilibrium...

Tax benefits to owner-occupied housing provide incentives for housing consumption, offsetting weaker disincentives of the property tax. These benefits also help counter the penalty federal taxes impose on households who work in productive high-wage areas, but reinforce incentives to consume...

Federal deductibility for state and local taxes constitutes one of the largest tax expenditures in the federal budget and provides a significant source of federal support to state and local governments. Deductibility was restricted in the Tax Reform Act of 1986 by removing the deduction for...

Fourteen U.S. states recently pledged to adopt limits on greenhouse gases (GHGs) per mile of light-duty automobiles. Previous analyses predicted this action would significantly reduce emissions from new cars in these states, but ignored possible offsetting emissions increases from policy-induced...

Victory in the War for Independence brought a vast amount of land within the grasp of the new American nation -- territory stretching from the Appalachian Mountains to the Mississippi River between the southern shores of the Great Lakes and Spanish Florida. These lands were initially claimed by...
