This paper studies how to design a fiscal constitution that, by capitalizing intergenerational spillovers into land values, is able to protect future generations from expropriation and to generate optimal investment in intergenerational public goods. In particular, we study how to accomplish...

The provision of public services through national legislatures gives legislators the chance to fund locally-beneficial public projects using a shared national tax base. Nationally-financed, local public goods will be purchased at a subsidized price below marginal cost and may be inefficiently...

We study the dynamic taxation of capital and labor in the Ramsey model under the assumption that taxes and public good provision are decided by a self-interested politician who cannot commit to policies. We show that, as long as the discount factor of the politician is equal to or greater than...

When comparing marginal costs and benefits of a public project, most economists think in terms of adding together the marginal costs of production plus marginal costs of additional distortionary taxation. This paper clarifies how the "revenue effect" offsets the "distortionary effect." For...

This paper illustrates how one can use causal effects of a policy change to measure its welfare impact without decomposing them into income and substitution effects. Often, a single causal effect suffices: the impact on government revenue. Because these responses vary with the policy in...

Tax reforms are sometimes touted to have strong macroeconomic growth effects. We consider the impact of a major tax reform on the long-term growth rates of the U.S. economy using three approaches. The first approach is to examine the historical record of the U.S. economy to evaluate whether tax...

South Africa's transition from apartheid to democracy stands as one of the past century's most important political events. The transition has been successful to this point because the new constitution adopted a form of federal governance that has been able to provide protection for the economic...

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...
