Job Market Paper

Tax complexity imposes significant costs on society, yet we know little about its political determinants. Does political competition drive tax complexity? I examine this question in the context of the US. I capture political competition by the closeness of elections and tax complexity by the prevalence of tax expenditures (TEs) (exemptions, deductions, and credits). I use machine learning to identify TEs in a novel dataset of over 3.1 billion words of legislative text built from the State Session Laws spanning 121 years (1900-2020). I find that overall political competition leads to fewer TEs. Importantly, this effect varies by party control. When elections are close, Republican-led legislatures enact more TEs than Democrats, particularly when campaign contributions from wealthy donors are large. Their strategy is to obfuscate the true tax burden on high-income earners by increasing tax complexity via TEs in order to win elections. These results challenge the conventional view that political competition uniformly improves policy outcomes, showing instead that its effects depend on partisan incentives.

Working Papers

We study how national political shocks that reveal xenophobic sentiment affect hate crime. We develop a social-norms model in which individuals care about matching both local and national behavior, but only observe local attitudes toward immigrants. Electoral outcomes that unexpectedly signal strong national anti-immigrant sentiment therefore generate larger “belief shocks” in locally tolerant areas, encouraging xenophobic individuals there to express hostility more openly. We test the model using data on racially and religiously motivated hate crimes in all 304 Community Safety Partnerships in England and Wales from 2002–2019, combined with pre-event attitudes and beliefs from the British Election Study. Difference-in-differences estimates show that a one–standard-deviation higher pre-event pro-immigrant attitude is associated with a 0.11 standard-deviation increase in hate crime after the UK Independence Party’s 2014 European election victory and a 0.16 standard-deviation increase after the 2016 Brexit referendum. Belief-shock measures and survey evidence on the expression of anti-immigrant views support the proposed mechanism.

We study to what extent the implementation of evaluation laws affects reported tax expenditures. We exploit the staggered introduction of tax incentives evaluation laws (TIELs) in US states, from 1999 to 2019. Using a novel digitized database of states’ tax expenditures and an event study approach based on the year these laws were enacted, we show that evaluation laws matter for transparency. We find that following the implementation of TIELs, reported tax expenditures increased on average by 14%, equivalent to about 2.44 billion USD at 2023 prices. This effect persists even four years after the laws are introduced. However, we find no changes in states’ tax revenues and direct spending after the TIELs were passed, which indicates that the observed higher reported tax expenditures correspond to previously hidden undisclosed tax expenditures provisions. We explore some mechanisms and find that the results are driven by states that are “making progress” in strengthening evaluation practices and by those that have a long budget cycle. Moreover, we explore potential electoral consequences for the ruling party. We find no effect on incumbent voting share. Finally, using text analysis to identify tax expenditure provisions in the tax legislation, we do not find a similar transparency effect in trying to make tax expenditure clauses more understandable for taxpayers.

“Venezuela at the stage of macroeconomic collapse: A historical and comparative analysis” (with Jose Manuel Puente), Journal America Latina Hoy (2020).

This paper conducts a historical and comparative analysis of GDP for 192 countries over the period 1980-2018 using data from the IMF. Results show that Venezuela lost 49.32% of its total GDP in just five years (2014-2018). This negative performance represents the worst macroeconomic performance in magnitude and duration in Venezuela history (1950-2018), the worst in Latin America and the second worst in the world during the period 1980-2018.
