Redistributive Taxation under Ethical Behaviour*
研究了当纳税人根据税收是否道德来调整劳动供给时，再分配税收制度的效果，发现道德行为使劳动供给弹性降低，并比较了道德与利己行为下的均衡税率。
Abstract We consider the implications of ethical behaviour on the effect of a redistributive tax‐transfer system. In choosing their labour supplies, individuals take into account whether their tax liabilities correspond to what they view as ethically acceptable. If tax liabilities are viewed as ethically acceptable, a taxpayer behaves ethically, does not distort her behaviour, and chooses to work as if she were not taxed. On the other hand, if ethical behaviour results in tax liabilities that exceed those that are ethically acceptable, she behaves egoistically (partially or fully), distorts her behaviour, and chooses her labour supply taking into account the income tax. We establish taxpayers' equilibrium behaviour and obtain that labour supply is less elastic when taxpayers may behave ethically than when they act egoistically. We characterise and compare the egoistic voting equilibrium linear tax schedules under potentially ethical and egoistic behaviour. We also compare our results to those obtained under altruism, an alternative benchmark.
