The research interests of Obama's pick to chair his Council of Economic Advisers (with highlights):
[Princeton economist Alan] Krueger has done leading research on why a minimum wage does not increase joblessness and why job growth can lag during otherwise prosperous economic time. [uncertainty?] He served as chief economist in the Treasury Department from March 2009 until November 2010 ....
During his time at Treasury, Krueger advocates a number of key administration measures designed to stimulate the economy, including a tax cut for businesses that hire new workers, the "cash for clunkers" auto trade-in program, and "Build America Bonds" that allowed states and localities to raise funds for building roads and other construction projects.
BTW, I don't know why the Senate has to confirm the President's advisers. But the hearings could be amusing.
