A research paper written on the effects of taxation and the tax and transfer sys

A research paper written on the effects of taxation and the tax and transfer system on inequality. I want to specifically look at negative income tax, corporate tax rate, and the earned income tax credit. How would changing to either of these help shift inequality and the income distribution to be more equal? Specifically, if we expand the earned income tax credit to help those in poverty.
