FINAL "Who Really Benefits From Consumption Tax Cuts? Evidence From a Large VAT Cut in France" with Dorian Carloni (CBO). AEJ: Economic Policy, Forthcoming. NBER Working Paper No. 23848. Vox Summary, IPP Policy Brief, featured in Alternatives Economiques, Le Figaro, France 2, France 3, Liberation.
NEW "Are Taxes Turning Humans Into Machines? Using Payroll Tax Variation to Estimate the Capital-Labor Elasticity of Substitution." with Jarkko Harju (VATT).
This paper provides a quasi-experimental estimate of the micro capital-labor elasticity of substitution. We use a discontinuity in the average payroll tax rate to show that firms decrease both labor and capital when experiencing higher payroll tax rates. We argue that this is consistent with Leontief production functions, implying a micro capital-labor elasticity of substitution of zero. Using a conceptual framework to aggregate micro elasticities, we estimate a macro capital-labor elasticity of substitution of 0.17. Our finding sheds new light on the role of the substitution of labor with capital in the fall of labor shares and on the fiscal externalities imposed by payroll taxes.
Revised "What Goes Up May Not Come Down: Asymmetric Incidence of Value Added Taxes" with Dorian Carloni (CBO), Jarkko Harju (VATT) and Tuomas Kosonen (LIER). NBER Working Paper No. 23849. Featured in Les Echos, L'Express, Capital, LCI, Ouest France, BFM.
This paper shows that prices respond more to increases than to decreases in Value-Added Taxes (VATs). First, using two plausibly exogenous VAT changes, we show that prices respond twice as much to VAT increases than to VAT decreases. Second, we show that this asymmetry results in higher equilibrium profits and markups and, therefore, benefits mainly firm owners. Third, we show that the asymmetry persists several years after the VAT changes take place. Fourth, we document additional empirical features of this asymmetry that are inconsistent with standard incidence models. Fifth, using all VAT changes in the European Union from 1996 to 2015, we find similar levels of asymmetry for most commodities in the economy and across most EU countries. Using a survey of firm managers, we provide possible explanations for our empirical findings.
Revised “How Taxing Is Tax Filing? Using Reveal Preferences to Estimate Compliance Costs.” NBER Working Paper No. 23903.
Featured in the LA Times, Le Figaro, Time, the Blade, Quartz, NPR, Washington Post and the NBER Digest.
This paper uses a quasi-experimental design and a novel identification strategy to estimate the cost of filing income taxes. First, using US income tax returns, I observe how taxpayers choose between itemizing deductions and claiming the standard deduction. Taxpayers forgo tax savings to avoid compliance costs, which provides a revealed preference estimate of the compliance cost of itemizing. I find that this cost increases with income, consistent with a higher opportunity cost of time for richer households. Second, using my estimates and estimates of the time required to file other schedules, I estimate the cost of filing federal income taxes. I find that this cost has been increasing since the 1980's and has reached 1.2% of GDP in the most recent years.
"Should I Stay Or Should I Go? The Migration Patterns of High-Skilled Workers: Evidence From Alumni Databases."
This paper uses a novel dataset to provide new series on the international migration of high skilled workers educated in France from 1944 to 2012. I use alumni databases to track the location of graduates from leading French post- secondary institutions. The proportion of high skilled individuals working in France has been steadily decreasing from 1944 to 2004. Recent years have seen an increase in the percentage of graduates staying in France in contradiction with the view that high taxes and administrative costs have been leading high skilled workers to leave France.
