"Costs of Gaming a Tax System: Evidence from Australian Taxation Data," with Robert Breunig, Shane Johnson and Miguel Olivo-Villabrille.

Abstract: We provide the first estimate of heterogenous costs of tax avoidance effort and elasticity of taxable income with respect to net-of-tax rate for high-income individuals. Despite the economic growth in recent years, income inequality has been on the rise worldwide. Governments use income taxes as a policy instrument to redistribute wealth from wealthy individuals to poor ones. However, there are concerns about the effectiveness of such policies as these policies themselves provide incentives for high- income individuals to take advantage of the complexity of the system, hide their wealth to reduce their taxable income. We exploit a unique policy change in Australian income tax schedule in 2009 which increased the top tax threshold to 180 thousand from 150 thousand. The marginal taxes below and above the threshold are respectively 40 and 45 percent. This policy change induces large incentives to game the tax system. Individuals face incentives to locate – “bunch”– right below the threshold where the marginal taxes are lower. After the policy change, some individuals bunch at the new threshold while some others continue bunching at the former threshold, suggesting that they face costs adjusting their income. We use the amount of bunching at the new and former thresholds to estimate an elasticity of taxable income respect to net-of-tax rate and heterogenous costs of tax avoidance effort that vary by individual’s potential income. We use administrative data from the Australian Taxation Office for our empirical analysis. Our study sheds light on individuals’ tax avoidance effort and channels through which they might game the system. Our findings would guide tax authorities where to target tax audits.

"Does More Information Results in Better Health- care? Evidence from National Broadband Network (NBN) Expansion in Australia," with Gideon Aschwanden and Diana Contreras Suarez.

Abstract: We investigate whether more information affects doctors’ behaviour in prescribing new drugs. Doc- tors have accesses to more health-related information where internet is the main source. More information should lead to better choices, but a doctor’s choice for adopting new drugs could be quite complex. We explore geographical discontinuity in the expansion of NBN as an exogenous source of variation in doctors’ access to the internet using a Regression Discontinuity Design (RDD) model. We use doctors’ information from the Medicine in Australia: Balancing Employment and Life (MABEL) data linked to doctors’ prescription data from the Medical Benefits Schedule (MBS) for our empirical analysis. A better understanding of the impacts of improved information access on health outcomes and health care utilization would help in designing more effective policies to improve the population health and maintaining the sustainability of the health care system.

"Working while Unemployed? Evidence from a Work While on Claim Program," with Claudio Labanca and Adam Lavecchia.

Abstract: We investigate how a change in work incentives in an Unemployment Insurance (UI) program affect the labor supply behaviour of its benefit recipients. We explore a policy change in a Working While on Claim (WWC) program in Canada which allows beneficiaries to work up to an exemption threshold while collecting UI benefits. The policy change increased the threshold to 75$ per week or 40% of their UI benefits from 50$ per week or 25% of their UI benefits in 23 Canadian regions with Unemployment rates of 10% or above. Using an administrative data, we estimate the intensive margin effects on labor supply of beneficiaries using a Difference-in-Differences (DD) framework. We use economic regions with unemployment rates lower than 10% as a control group. The policy change also can affect individuals’ decision to start working. We estimate the extensive margin effects using a Regression Kink Design (RKD). We use individuals’ UI benefit to recover their earnings before entering the UI program and use it as individuals’ potential earnings in our RKD model. Our findings have important implications for designing UI benefits.
