At macroblog, Julie L. Hotchkiss, a research economist and senior policy adviser at the Atlanta Fed, and Fernando Rios-Avila, a research scholar at the Levy Economics Institute of Bard College look at the relationship betwen education and inequality:
... There is little debate about whether income inequality has been rising in the United States for some time, and more dramatically recently. The degree to which education has exacerbated inequality or has the potential to reduce inequality, however, offers a more robust debate. We intend this post to add to the evidence that growing educational attainment has contributed to rising inequality. This assertion is not meant to imply that education has been the only source of the rise in inequality or that educational attainment is undesirable. The message is that growth in educational attainment is clearly associated with growing inequality, and understanding that association will be central to the understanding the overall growth in inequality in the United States.
