The revolving door between Congress and lobbying firms appears to have been central to how the financial sector became deregulated, which effectively allowed excessive risk-taking in the run-up to the crisis. In another paper, Igan and Mishra, working with Thierry Tressel, found that firms taking more risks before 2008 were also engaged in more lobbying.
国会和游说集团之间的旋转门似乎是金融部门逐渐去监管化的关键，而去监管化又导致了过度的风险承担，引发了危机。在另一篇论文中，伊甘、米什拉和特雷塞尔（Thierry Tressel）一起发现，在2008年之前承担风险越多的公司，在游说中用力也最多。
