Christina Romer is leaving the Obama administration.

Romer, who chairs the Council of Economic Advisers, announced Thursday night that she is returning to her previous job as economics professor at the University of California at Berkeley.

Her resignation follows that of budget director Peter Orszag.

In a statement, Romer called the her White House service the “honor of a lifetime.”

It will be interesting to see whether we’ll see any policy changes. Romer is an expert in the Great Depression and was instrumental in the stimulus package. In many ways she has served her purpose, and now the administration can shift to sustained growth as opposed to the crisis management of the past 18 months.
