Yellen is considered by many on Wall Street to be an Inflation Dove (as concerned with unemployment as inflation) and as such is less likely to advocate Federal Reserve interest rate hikes, as compared, for example, to William Poole (St. Louis Fed President) an Inflation Hawk (see definitions under Inflation).

In July 2009, Yellen was mentioned as a potential successor to Ben Bernanke as chairman of the Federal Reserve System, before he was renominated by Barack Obama.

On April 28, 2010, President Obama nominated her to be the successor to Donald Kohn as vice-chairman of the Federal Reserve System.

She is married to George Akerlof, a Nobel prize-winning economist and professor emeritus at the University of California, Berkeley.

According to Fed Salary figures released for 2010 she earns $410,000 per year, more than the Chairman Ben Bernake ($199,700) whose pay is limited by law. (WSJ 5/25/10)
