Lloyd Shapley, one of two Americans who were awarded the Nobel economics prize, is photographed at his home in the Pacific Palisades area of Los Angeles Monday, Oct. 15, 2012. Shapley, 89, and Alvin Roth were awarded the Nobel economics prize on Monday, for studies on the match-making that takes place when doctors are coupled up with hospitals, students with schools and human organs with transplant recipients. The work of Roth and Shapley has sparked a flourishing field of research and helped improve the performance of many markets, the Royal Swedish Academy of Sciences said. Shapley is a professor emeritus at University of California Los Angeles. (AP Photo/Reed Saxon)
