We assess the business provisions of the 2017 Tax Cuts and Jobs Act, the biggest corporate tax cut in US history. We draw five lessons. First, corporate tax revenue fell by 40 percent due to the lower rate and more generous expensing. Second, firms with larger declines in their effective tax...

In the second half of the 2010s more than 100 countries--including all large offshore financial centers--started to automatically exchange bank information with foreign tax authorities. This informational big-bang marks a break with the situation of offshore bank secrecy that prevailed before....

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...

The real economic cost of homeownership depends on an intricate system of taxes and subsides that vary over time and across the United States. We incorporate the key features of this system into a framework for measuring the annual user-cost of housing and we use it to document how housing costs...

By preemptive austerity, we mean a policy that increases taxes to deter potential rollover crises. The policy is so successful that the usual danger signal of a rollover crisis, a high yield on new bonds sold, does not show up because the policy eliminates the danger. Mechanically, high taxes...

Employment and participation rates for US prime age women rose steadily during the second half of the 20th century. In the last 30 years, however, those rates stagnated, even as employment and participation rates for women in other industrialized countries continued to rise. I discuss the role...

Inefficiencies from tax competition may result in governments seeking to limit fiscal competition via tax treaties, harmonization, minimum tax rates, or interjurisdictional cooperation. I propose a general model applicable to studying many types of taxing instruments, which allows for the...

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,...

A key contention in economics is the discrepancy between micro and macro elasticities of labor supply with respect to marginal tax rates. We revisit this question, focusing on the role of dynamic returns to effort among top earners. We develop a new model of earnings responses to taxes in the...

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...
