I have read the research disclosure policy. My funding sources are as follows: the E. Morris Cox fund at the University of California, Berkeley, the Presidential fund at USC, the Schaeffer Center for Health Economics and Policy at USC, and National Institute on Aging (NIA) grants No. P01 AG005842 to the NBER and No. RC4 AG039036 to USC. I have no financial conflicts of interest.
