Job transitions in the US banking between the regulatory and private sector – or the revolving door – have been under intense scrutiny, receiving both criticism and more benign views.

The results suggest lower employment spells of regulatory personnel in more recent years and for workers with higher education. Tightening the revolving door without altering other aspects of worker incentives may further create challenges for regulatory agencies to seek and retain talent.
