Optimal tax theory has difficulty rationalizing high marginal tax rates at the upper end of the income distribution. In this paper, I construct a model of optimal income taxation in which agents' preferences are interdependent. I derive a simple expression for optimal taxes that accommodates...

We develop a three stage game model composed of a regulator and two firms. These firms compete on the same market where they offer the same homogeneous good, and can invest in R&D to lower their emission/output ratio. By means of a tax per-unit of pollution and a subsidy per-unit of R&D level,...

This paper analyzes the effects of consumption externalities on optimal taxation and on the social cost and optimal levels of public good provision. If public and private goods are Hicksian complements and no lump sum taxes are available, the second-best level of public good provision can exceed...

This paper analyzes the effects of non-atmospheric consumption externalities on optimal commodity taxation and on the social cost and optimal levels of public good provision. A negative consumption externality, by lowering the social cost of public good provision, may require the second-best...

This paper deals with tax policy responses to charitable giving, defined in terms of voluntary contributions to a public good, to which the government also contributes through public revenue; the set of tax instruments contains general, nonlinear taxes on income and charitable giving. In addition...

In light of the increasing inequality in many countries, this paper analyzes redistributive charitable giving from the rich to the poor in a model of optimal nonlinear income taxation. Our framework integrates (i) public and private redistribution, (ii) the warm glow of giving and stigma of...
