We study how government policies and corporate commitments to decarbonize interact under two externalities: environmental damages and green innovation spillovers. Unconstrained carbon taxes and innovation subsidies could achieve first-best outcomes, but when government policies face constraints,...

The quality and inequality of US drinking water investments have gained attention after recent environmental disasters in Flint, Michigan, and elsewhere. We compare the formula-based targeting of subsidized loans provided under the Safe Drinking Water Act with the targeting of congressional...

What is a feasible and efficient policy to regulate air pollution from vehicles? A Pigouvian tax is technologically infeasible. Most countries instead rely on exhaust standards that limit air pollution emissions per mile for new vehicles. We assess the effectiveness and efficiency of these...

We study the role of trade policy in one of the most pressing climate policy challenges that developing countries face: meeting voluntary emission restraints (VERs). To do so, we develop a general equilibrium trade model that extends Caliendo and Parro (2015) in three dimensions. First, we model...

This paper asserts that reporting of the ratio of welfare gains to tax revenue should be standard protocol in economic analyses of externality correcting taxes. That this comparison might matter is somewhat of a "blind spot" in most economic analyses, for it plays virtually no role when...

Entitlement programs have become an increasing component of total government spending in the US over the last six decades. To some observers, this growth of the welfare state is excessive and unwarranted. To others, it is a welcome counter-acting force to the rapid increase in income inequality....

This paper investigates the 2013 three-fold increase in the French dividend tax rate. Using administrative data covering the universe of firms from 2008-2017 and a quasi-experimental setting, we find that firms swiftly cut dividend payments and used this tax-induced increase in liquidity to...

While "'Tis impossible to be sure of any thing but Death and Taxes" (Bullock, 1716), the structure of taxes and their burden has undergone large and frequent changes over time. We provide a brief history of the U.S. federal income tax reforms since the 1960s, we calculate effective federal...

How do different income taxation systems affect household decisions and welfare? We answer this question by first documenting the strong labor supply disincentives for secondary earners of the U.S. tax system and by using variations from the Bush Tax Cuts to assess their effects on...

The share of pre-tax income flowing to the top of the UK income distribution increased continually and substantially in the three decades leading up to the financial crisis, but has changed little since 2013. Using microdata sampled from UK tax records, we describe the nature of top incomes in...
