"Permanent and Transitory Responses to Capital Gains Taxes: Evidence from a Lifetime Exemption in
Canada"
(with Adam Lavecchia) NBER Working Paper 28514 Non-technical summary Slides
Using panel data on a 20% random sample of Canadian taxpayers, we study behavioral responses to the cancellation of a lifetime capital gains exemption that resulted in increased capital gains taxation for some individuals. The unique setting allows us to distinguish between short-term avoidance responses and permanent responses to capital gains taxes. We show that the exemption did not change the number of taxpayers reporting positive capital gains, and thus unlikely resulted in increased participation in capital markets. However, the exemption cancellation slightly increased capital gains realizations of the existing traders.

"What Drives Tax Policy? Political, Institutional and Economic Determinants of State Tax Policy in the Past 40 Years"
(with Sarah Robinson)
We use data on U.S. state tax rules over the past 40 years to shed light on the determinants of U.S. state tax policy. Our analysis generates three key results. First, we show that after a period of similarity during the 1990s, tax policies of Republican and Democratic states started to diverge, with Democratic states exhibiting higher tax rates on average. Second, we find that this divergence is not due to convergence within Republican/Democratic states. Instead, we observe large heterogeneity in tax levels and in the frequency, direction, and magnitude of tax changes that is not explained by party control, tax structures or by the size of tax changes. Third, we show that the timing and magnitude of tax changes are difficult to predict. Overall, federal changes, economic needs, neighborly competition, institutional features, political factors and demographics explain less than 15% of variation in the timing and magnitude of tax changes.

"Labor Supply Responses to Payroll Taxes in the UK"
I study behavioral responses to changes in marginal tax rates of social security and income taxes. I find that responses depend on individual’s employment status: whether a worker is a wage earner, self-employed, or a proprietor. In line with the existing literature I document weak (but statistically significant) bunching at kink points of the tax schedule among wage earners. Starting from 1999, wage earners accumulate pension credits when they exceed a certain threshold, however, no contributions are due until earnings reach a second, higher threshold. Even 10 years after this reform I find no bunching to the right of the eligibility threshold, suggesting that individuals do not assign a high value to pension benefits. Lack of bunching is persistent across age groups and unlikely to be explained by friction costs as individuals are able to bunch at other kink points. I find strong responses to tax incentives among the self-employed but the responses differ by the type of kink. I find sharp bunching at the first kink, medium bunching at the top kink and weak bunching at the middle kink. Comparing responses before and after a tax reform that changed the magnitude of kinks I find that self-employed individuals aggressively reduce earnings to bunch at the lower, more salient kink points. Finally, I document large income shifting by proprietors: many firm owners report most of income as dividends thus avoiding social security taxes. Nevertheless many proprietors choose to pay themselves sub-optimally high wages thus incurring an unnecessarily high tax liability. I show that some of these proprietors pay multiples of £5,000 or £6,000.
