This paper considers questions about the implications of rising inequality for the theory and practice of public finance. It begins by addressing fundamental reasons why the distribution of income or wealth on an annual basis before taxes and transfers offers insufficient information: (1) it...

Economists often regard broad-based carbon pricing (whether in the form of a carbon tax or cap and trade) as the most efficient policy to reduce carbon dioxide emissions. Relative to a narrower policy that exempts some emissions sources, a broader policy is often favored because it can exploit...

A unilateral carbon tax trades off the distortionary costs of taxation and the future gains from slowing down global warming. Because the cost is local and immediate, whereas the benefit is global and delayed, this tradeoff tends to be unfavorable to unilateral carbon taxes. We show that this...

We study carbon border adjustment mechanism (CBAM) policies, as currently being implemented by the EU and UK. Policy discussions have cited three motivations and one concern. CBAMs can improve domestic competitiveness in regulated markets, reduce emissions leakage to unregulated markets, and...

In our analytical general equilibrium model where two polluting inputs can be substitutes or complements in production, we study the effects of a tax on one pollutant in two cases: one where both pollutants face taxes and the second where the other pollutant is subject to a permit policy. In...

This paper considers how policy updates and trading of regulated quantities over time changes the traditional comparative advantage of prices versus quantities. Quantity regulation that can be traded over time leads firms to set current prices equal to expected future prices. A government...

The philanthropic sector is highly consequential, particularly in the United States, and the most important policies directed toward this sector are tax policies. Yet most economic analysis of the optimal tax treatment of charitable giving is ad hoc, treating it as a subject unto itself. This...

This paper reviews the literature on the incidence of consumption and labor taxes and focuses on the empirical results that show stark departures from the canonical model of tax incidence, which I refer to as anomalies. In particular, there is mounting evidence questioning three fundamental...

Carbon taxation is a widely proposed and in some countries already adopted means to limit anthropogenic climate change. This paper studies carbon taxation using an 18-region, 80- period overlapping generations model. We focus on carbon policy that delivers present and future mankind the highest...

Experiences in real-world pollution markets suggest that firms make persistent errors in forecasting allowance and credit prices that inform their investment decisions. The residual uncertainty characterizing allowance and credit trading means that pollution markets may fail to deliver...
