Income inequality and economic growth in an open economy

Income inequality has a strong impact on fiscal policy when majority voting enables those individuals with less-than-average income to decide on tax rates. This study analyzes the impact on economic growth of income inequality in an open economy where tax revenues are partially used for international transfers. In any case, income inequality is harmful for growth. In an economic union, positive effects of international integration raise the growth rate as long as net transfers do not grow proportionally. In a political union, unionwide voting makes distributive politics depending on the union's median voter. In this case, additional output growth on aggregate level is a necessary, but not sufficient condition for a majority of voters to accept union membership.
