Who Benefits from State Corporate Tax Cuts? A Local Labor Markets Approach with Heterogeneous Firms [JOB MARKET PAPER] 
    (with Juan Carlos Suárez Serrato)
    Manuscript, December 2013. Slides, January 2014.
                  
Abstract: This paper estimates the incidence of state corporate taxes on workers, landowners, and firm owners in a spatial equilibrium model in which corporate taxes affect the location choices of both firms and workers. Heterogeneous, location-specific productivities and preferences determine the mobility of firms and workers, respectively. Owners of monopolistically competitive firms receive economic profits and may bear the incidence of corporate taxes as heterogeneous productivity can make them inframarginal in their location choices. We derive a simple expression for equilibrium incidence as a function of a few estimable parameters. Using variation in state corporate tax rates and apportionment rules, we estimate the reduced form effects of tax changes on firm and worker location decisions, wages, and rental costs. We then use minimum distance methods to recover the parameters that determine equilibrium incidence as a function of these reduced form effects. In contrast to previous assumptions of infinitely mobile firms and perfectly immobile workers, we find that firms are only approximately twice as mobile as workers over a ten-year period. This fact, along with equilibrium impacts on the housing market, implies that firm owners bear roughly 40% of the incidence, while workers and landowners bear 35% and 25%, respectively. Finally, we derive revenue-maximizing state corporate tax rates and discuss interactions with other local taxes and apportionment formulas.

Tax Cuts for Whom? Heterogeneous Effects of Income Tax Changes on Growth and Employment 

    Slides and Manuscript from NBER Summer Institute - Public Economics. July 2013.

Abstract: This paper investigates how tax changes for different income groups affect macroeconomic activity. Using historical tax return data from NBER’s TAXSIM, I construct a measure of who received (or who paid for) postwar tax changes for each income and payroll tax change that Romer & Romer (2010) classify as exogenous. At the national level, I aggregate tax changes for all taxpayers in the bottom 90% and the top 10% of AGI and relate these aggregates to output, employment, and consumption growth. At the state level, I construct Bartik instruments for state tax shocks using national tax changes and each state’s share of high income taxpayers. If tax cuts for high income earners generate substantial economic activity, then states with a large share of high income taxpayers should grow faster following a tax cut for high income earners. I find that the negative relationship between tax changes and real GDP growth over a two year period is almost entirely driven by tax changes for the bottom 90%. The empirical relationship between tax cuts for the top 10% percent and job creation is negligible in magnitude, statistically insignificant, and much weaker than that of equivalently sized tax cuts for the bottom 90%.

Resume Padding Among Economists
    (with Christopher Snyder)
    Manuscript. December 2011.

Abstract: The policy of the American Economic Review (AER) to publish unrefereed papers in the same volume as refereed ones gives economists the opportunity to pad their resumes by trying to pass Papers & Proceedings off as refereed AER articles. Using unique data on curricula vitae of economists at the top 25 U.S. economics departments, we provide preliminary evidence in support of deliberate obfuscation. Economists with more Papers & Proceedings are more likely to list them in a way that is difficult to distinguish from refereed ones. We then go on to provide support for a more benign explanation, that the convention guiding how one should document Papers & Proceedings is in transition and varies across communities of scholars. We provide a series of difference-in-differences analyses of citation behavior, both at the level of demographic groups and individuals, showing that economists who cite Papers & Proceedings more tend to be the ones who “pad” more, suggesting both are correlated with an additional latent factor — a judgment about the journal’s prestige.

Campaigning in Poetry: Candidates' Choice of Words in the 2008 Election
    (with Bruce Sacerdote)
    Manuscript. January 2008.

Abstract: We construct and analyze a database consisting of the words used in speeches made by the candidates in the 2008 Democratic and Republican Presidential Primary. We present findings in two key areas. First, we estimate which candidates are more negative by counting the number of times they mention their opponents by name. Both Obama and Clinton are among the least negative. John Edwards is 3.7 times more negative than Barack Obama and Mitt Romney is 4.7 times more negative than Obama. We also compare the speeches of the candidates to speeches delivered by famous political figures and orators such as Martin Luther King, Ronald Reagan, and John F. Kennedy. For example, we can ask whether a candidate's words are more like those of MLK versus Ronald Reagan. Using our metric, John McCain and Mitt Romney are the most like Ronald Reagan whereas (within the set of primary candidates) the words of Mike Huckabee and Barack Obama are the closest to those of Martin Luther King. Hillary Clinton is by far the candidate closest in oratory to Bill Clinton.
