She is relatively moderate on many topics, including trade. Mr. Akerlof recalled in a biographical note in 2001 that when he met her: “Not only did our personalities mesh perfectly, but we have also always been in all but perfect agreement about macroeconomics. Our lone disagreement is that she is a bit more supportive of free trade than I.”
Ms. Yellen has been a major influence on leading officials at the Fed. John C. Williams, who worked for her in San Francisco, now leads the Federal Reserve Bank of New York. Mary C. Daly, who now leads the San Francisco Fed, cites Ms. Yellen as a key mentor.
That, along with Ms. Yellen’s experience working with Mr. Powell, could help facilitate the kind of close relationship needed between the Fed and Treasury, which are collaborating on a variety of crisis response programs.
Henry M. Paulson Jr., who served as Treasury secretary under President George W. Bush, praised the selection. He said Ms. Yellen “will have a tough job ahead of her, but she has the experience, talent, credibility and relationships with members of Congress on both sides of the aisle to make a real difference.”
While the other leading contenders for the job also had extensive experience that spanned fiscal and monetary policy, Ms. Yellen was seen as well placed to make it through Senate confirmation, even if Republicans maintain control of the chamber.
Lael Brainard, another top candidate for the role, is the only remaining Fed governor from the Democratic Party on the seven-member board, which currently has two open slots. She might have been difficult to replace at the Fed: Nominees have been hard to confirm over the past decade, and the Senate may remain under Republican control.
While leading the Fed, Ms. Yellen at times had a testy relationship with congressional Republicans. In one instance, Representative Mick Mulvaney, then a South Carolina Republican, said Ms. Yellen was overstepping her boundaries by talking about inequality.
