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...

Using data on U.S. state and federal taxes and transfers over a quarter century, we estimate a regression model that yields the marginal effect of any shift of market income share from one quintile to another on the entire post tax, post-transfer income distribution. We identify exogenous income...

US universities have attracted hundreds of thousands of international students each year for the last decade. Some of these remain in the US after graduating and contribute to the high skilled labor supply in US labor markets. In this paper, we identify and estimate by how much one more...

We use an instrumental-variables estimator reliant on variation in congressional representation to analyze the effects of federal aid to state and local governments across all four major pieces of COVID-19 response legislation. Through September 2021, we estimate that the federal government...

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...

The COVID-19 related public health emergency led to federal legislation that changed the landscape of Medicaid coverage for low-income people in the United States. Beginning in 2020, policy responses led to a surge in Medicaid enrollment due to federal rules preventing Medicaid disenrollment,...

We study the relationship between housing supply and political partisanship in US cities using a new database of mayoral elections combined with local housing permits since 1980. Endogeneity of which party holds the mayoral office is addressed via a regression discontinuity design that relies on...

This paper develops a new approach to detecting electoral fraud. Our context involves repeaters, individuals voting in multiple states in the U.S. during 19th Century Congressional Elections. Given high travel times, and the associated difficulties of voting in multiple states on the same day,...

Our purpose is three-fold. First, we summarize some of the core insights from both classic and more recent papers in the literature on the role of intergovernmental grants in systems of fiscal federalism. Second, we provide an updated look at some of the key institutions through which...

We collect detailed data on U.S. state personal income, corporate, sales, cigarette, gasoline, and alcohol taxes over the past 70 years to shed light on the determinants of state tax policies. We provide a comprehensive summary of how tax policy has changed over time, within and across states....
