IMPACT OF PROGRESSIVE TAXATION ON INEQUALITY: ANALYZING THE INEQUALITY DEPENDENCE ON INCOME DISTRIBUTION PARAMETERS AND TAX PROGRESSION
Ekon. teor. 2017; 3:23-38 | |
ABSTRACT ▼
The article presents an investigation of the direct influence of progressive tax on income distribution and inequality. The case of lognormal distribution and a tax power function is considered. The coefficient Gini is applied to measure income inequality. It is shown that given progressive tax function doesn’t change the initial income distribution law: it will be lognormal with parameters depending on initial distribution parameters, tax progression and non-taxable income. The obtained mathematical dependences allow analyzing each parameter’s influence on net income distribution and reducing inequality. It is found out that the dependence of Gini coefficient on tax progression is linear if the distribution parameter is a small values (a distribution has a small dispersion), and non-linear at big values. The applications of the obtained theoretical findings are presented with a case study on Ukraine.
