We show that, in a setting where tax competition promotes efficiency, variation in the extent to which firms can use public goods to reduce costs brings about a reduction in the intensity of tax competition. This in turn brings about a loss of efficiency. In this environment, a `minimum tax'...

This paper argues that, because governments are able to relax tax competition through public good differentiation, traditionally high-tax countries have continued to set taxes at a relatively high rate even as markets have become more integrated. The key assumption is that there is variation in...

In a classic model of tax competition, we show that the level of public good provision and taxation in a decentralized equilibrium can be efficient or inefficient with either too much, or too little public good provision. The key is whether there exists a unilateral incentive to deviate from the...

We introduce a subsidized Vickrey auction for cost sharing problems. Although the average, marginal, and serial cost sharing mechanisms are budget-balanced, they are not allocatively efficient and they do not induce players to truthfully reveal their values as a dominant strategy. The...

The paper assumes a government advantage in collecting income contingent payments and develop a proposal for a government loan program that is an integral part of the tax system. The focus is on administrative costs and the difference between the collection technologies available to the public...

Comparative static properties of the solution to an optimal nonlinear income tax problem are provided for a model in which the government both designs a redistributive income tax schedule and provides a public input into a nonlinear production process. These assumptions imply that wage rates are...

The impacts of changing the number of individuals of a particular skill level on the solutions to two versions of the finite population optimal nonlinear income tax problem are investigated. In one version, preferences are quasilinear-in-leisure. For this version, it is shown that it is possible...

Comparative static properties of the solution to an optimal nonlinear income tax problem are provided for a model in which the government both designs an income tax schedule for redistributive purposes and provides a public good optimally. There are two types of individuals, distinguished by...

The welfare gains from adopting a zero nominal interest policy depend on the implementation details. Here I focus on a government loan program that crowds out lending and borrowing and other money substitutes. Since money can be costlessly created the resources spent on creating money...

Diamond and Mirrlees have shown that public sector shadow prices should be set equal to the private producer prices in some circumstances even if taxes are not optimal when the public production technology is convex and some of the private sector firms have constant-returns-to-scale...
