I want to know the answer to the following question:
Who was the U.S. Federal Reserve vice-chair in April 2009?
All the background I'm provided with is that "He spoke of the paradox of deleveraging, in which precautions that may be smart for individuals and firms—and indeed essential to return the economy to a normal state—nevertheless magnify the distress of the economy as a whole."". Is that enough to answer the question?
Answer: no
