Occupy This: The Effect of Income Inequality on GDP Per Capita Growth Using Panel Data in the United States from 1963 to 2009

Income inequality and its relationship to long-term GDP per capita growth has been researched for decades since the development of the Kuznet’s Curve. Theoretical and empirical research has shown mixed results including positive, negative, non-existent, or statistically insignificant relationships. Empirical research on income inequality and economic growth in the United States has also shown mixed results. In addition to using existing data, this paper uses originally-constructed Gini Coefficients from 2005 to 2009. A statistically significant negative correlation between income inequality, and both short-term growth and long-term growth is found in the analysis of this data. Finally, this paper attempts to justify a causal relationship between income inequality and long-term growth.
