The Effects of the Value-Added Tax on Revenue and Inequality
利用新发布的宏观数据，通过固定效应回归和工具变量分析，发现增值税的引入并未增加政府收入，反而加剧了收入不平等，但消费不平等未受影响。
This paper examines the impact of the introduction of the value-added tax on inequality and government revenues using newly released macro data. We present both conventional country fixed effect regressions and instrumental variable analyses, where VAT adoption is instrumented using the previous values of neighbouring countries’ VAT systems as an instrument. The results reveal – in contrast to earlier work – that the revenue consequences of the VAT have not been positive. The results indicate that income-based inequality has increased due to the VAT adoption, whereas consumption inequality has remained unaffected.
