Abstract [sv]

Under 2000-talets början har inkomstojämlikhet ökat i världen. Det är omdebatterat vilka faktorer som ligger bakom och vilka medel som ska hantera problematiken. Uppsatsen undersöker ett av de vanligaste verktygen för att stävja inkomstojämlikhet, nämligen inkomstskatt. Syftet är att mäta vilken effekt inkomstskatt har på inkomstojämlikhet. För att uppfylla syftet tillämpas en instrumentvariabel regressionsanalys för att studera om inkomstskatt kan förklara inkomstojämlikhet i svenska kommuner under tidsperioden 2003–2017. Studien utmärker sig från tidigare studier inom området då en instrumentvariabel regressionsanalys använts för att exkludera att inkomstojämlikhet kan påverka nivå av inkomstskatt i en region. Statistiskt signifikanta resultat påvisar att inkomstskatt har negativ effekt på inkomstojämlikhet. Där en 1 procentenhets ökning i inkomstskatt leder till 2,08 procents minskning i inkomstojämlikhet.

Abstract [en]

During the beginning of the 21st century, income inequality has risen in most countries. What has caused this and how it should be solved is well debated. This paper intends to research one of the most well-known instruments to decrease income inequality, income tax. Our aim is to measure what effect income tax has on income inequality. To reach this aim we have applied an instrument variable regression analysis on income tax and income inequality, with Swedish municipalities during the timespan 2003-2017 as our selection group. This study distinguishes itself from previous studies in the area since we have used an instrument variable analysis to exclude the fact that income inequality can affect the level of income tax in a region. We have found significant results that income tax have a negative effect on income inequality and have concluded that a 1 percent increase in income tax will decrease income inequality with 2,08 percent.
