中文摘要
我们研究分权化财富税对流动性的影响，以及税收协调在缓解税收竞争方面的有效性。我们利用西班牙财富税的重新引入作为研究情境；此后，除马德里外，所有地区均征收正税率。我们发现，对财富税的流动性反应处于既有关于所得税估计的范围内。然而，财富税流动性反应导致的个人所得税收入损失，是财富税直接损失的六倍。若同意采用协调一致的正税率，马德里可以实现更高的地区总收入。(JEL D31, G51, H24, H71, H73, H77)
Abstract
We study the effects of decentralized wealth taxation on mobility and the effectiveness of tax coordination at mitigating tax competition. We exploit the reintroduction of the Spanish wealth tax, after which all regions except Madrid levied positive tax rates. We find the mobility responses to wealth taxes are within the range of prior estimates with respect to income taxes. However, wealth tax mobility responses generate losses to personal income tax revenues that are six times larger than the direct losses to wealth taxes. Madrid could achieve higher total regional revenues by agreeing to a harmonized positive tax rate. (JEL D31, G51, H24, H71, H73, H77)
