I'd reappoint him. If forced to choose between Yellen and Summers, I'd choose Yellen.
I agree. I think Bernanke has done a remarkable job, and I think his temperament is much better suited to the job than Summers' (not that it matters, I suppose, but I also prefer Bernanke's academic work to Summers'). I also worry about the appearance of having a Fed Chair who has taken such large speaking fees from companies that he would be regulating.
