Stanford economist Nicholas Bloom discusses the research he's conducted showing what\u2019s really driving the growth of income inequality: a widening gap between the most successful companies and the rest, across industries. In other words, inequality has less to do with what you do for work, and more to do with which specific company you work for. The rising gap in pay between firms accounts for a large majority of the rise in income inequality overall. Bloom tells us why, and discusses some ways that companies and governments might address it. He\u2019s the author of the Harvard Business Review article, \u201cCorporations in the Age of Inequality.\u201d For more, visit hbr.org/inequality.
