In this interview, Marriane Bertrand and Luigi Zingales talk about their views on how lobbying in the U.S. Congress exists, how effective it is, what its impacts are, and how it may have shaped the 2008 financial crisis. In the first half, the focus is on explaining lobbying and how it affects the government. The rest of the interview is spent on questioning the Booth professors on how Lobbying may have affected the regulation that was implemented on banks and other financial institutions before the 2008 financial crisis.
