Top Income Shares and Budget Deficits

The paper argues that the concentration of income at the top of the distribution, along with a decreasing taxation imposed on high incomes, may have affected OECD countries’ fiscal performances in recent decades. Using a panel of 17 OECD countries between 1975 and 2005, the paper presents the first reported evidence of a positive relationship between the top 1 percent income share and budget deficits. The disaggregated analysis of the budget components suggests that such result is due to a negative relationship between the concentration of income at the top and budget revenues.
