The US needs more flexible labor markets (Ryan Nunn, Brookings)

The United States is often thought to have an exceptionally fluid labor market, with workers able to easily move across states in response to changing economic conditions. Unfortunately, the famously flexible U.S. labor market has quietly become much less so. Workers are switching jobs at ever lower rates and moving across states less frequently since at least the 1970s. These declines are uneven in magnitude but consistent across states. Workers are also changing occupations atlower rates than in previous decades. On the employer side, firms are creating and destroying fewer jobs over time.
