Former Treasury Secretary Timothy Geithner’s book tour promoting Stress Test, his memoir of the 2008-9 crisis, has gotten eclipsed by Hillary Clinton’s book tour.  But the questions his apologia raises about if and when bailouts are appropriate, and whether our largest financial institutions are still “too big to fail,” still have not been resolved.  My instincts tend to be completely different than Geithner’s (no doubt one of the many, many reasons he’s the one who was Treasury Secretary), as reflected in this little column.
