Wealth inequality has prompted calls for higher taxes on capital income and wealth but also concerns that rich households would respond by concealing their assets offshore. We use a general equilibrium model to study how taxing capital more heavily would affect offshore tax evasion and how this would affect the broader economy. Without evasion, tax revenue could be increased dramatically, inequality could be reduced, and widespread welfare gains could be achieved. After accounting for evasion, however, tax revenue would rise marginally or even fall, inequality would increase, and widespread welfare losses would result.

逃税和资本税


财富不平等引发了对资本收入和财富征收更高税收的呼声，但也有人担心富裕家庭会通过将资产隐藏在海外来应对。我们使用一般均衡模型来研究对资本征收更重的税将如何影响离岸逃税，以及这将如何影响更广泛的经济。如果不逃税，税收收入就可以大幅增加，不平等就可以减少，并且可以实现广泛的福利收益。然而，在考虑逃税之后，税收收入将小幅上升甚至下降，不平等现象将加剧，并导致广泛的福利损失。
