Behavioral Responses to Wealth Taxes: Evidence from Sweden
利用瑞典行政数据，估计财富税对应税财富的弹性在0.09到0.27之间，并发现约三分之一的弹性来自资产价值低报，反应更多体现为逃税和避税而非储蓄变化。
This paper provides an empirical assessment of an annual wealth tax. Using Swedish administrative data, I estimate net-of-tax-rate elasticities of taxable wealth in the range [0.09, 0.27]. Cross-checking self-reported assets against asset data unavailable to the tax agency reveals that around a third of the elasticity estimates are due to underreporting of asset values. Difference-in-difference designs further suggest that the responses reflect evasion and avoidance rather than changes in saving.
