This article employs the Johansen and Engle–Granger methodology to determine if there is a cointegrating relationship between household debt and income inequality as measured by Atkinson, Piketty and Saez (2011). The results suggest a cointegrating relationship between the two series. A vector error correction model is estimated showing that a shock to household debt has statistically significant effects on income inequality in the United States over the time period 1919–2009.
