** FILE ** Nobel Prize winner and economics professor Daniel McFadden receives a congratulatory phone call as he walks to a news conference on the University of California, Berkeley campus in Berkeley, Calif., Wednesday, Oct. 11, 2000 after McFadden won the Nobel Prize in economics. McFadden joins five other prominent professors and scientists at UCB and the Lawrence Berkeley National Laboratory doing philanthropic work with the East Bay Community Foundation, who converted his prize winnings into a donor advised fund at the Foundation in 2000. McFadden was awarded the prize that year for his work in "microeconometrics," the study of how individuals and households make economic choices. "I do not think of philanthropy in abstract terms, as a moral imperative or as a prerequisite for a virtuous life," said McFadden. "I think of it in personal terms, helping family and helping your community as your extended family." (AP Photo/Paul Sakuma)
