December 17, 2008 / SFI External Professor Peyton Young and coauthor Dean Foster show how hedge funds have the power to deceive you in their study; The Hedge Fund Game: Incentives, Excess Returns, and Performance Mimics. They show how vulnerable the market is to unskilled traders. The unskilled trader may appear skilled and you wouldn’t know the difference until it is too late and the fund blows up.
December 16, 2008 / SFI External Professor Daniel Rockmore and coresearchers study the complex systems of the financial markets. Rockmore and colleagues created the “partition decoupling method” (PDM) which combines the partition scrubbing method and the hierarchical spectral clustering method. The PDM would be used for decomposing the correlation networks of the markets. The end result would reveal interdependencies in the network components. This information would be useful in risk management and portfolio construction.
Bette Korber, of the Santa Fe Institute, along with 21 other researchers — including Robert Gallo, co-discoverer of the AIDS virus- signed a short opinion piece recently published in the Journal of Science. The scientists believe that a $119 million federally funded experiment in which an AIDS vaccine is being tested on 16,000 volunteers in Thailand is doomed to fail and should never have been started. "They are taking two failed products and hoping that if they are combined that they are going to work," said Dennis Burton, an AIDS researcher at the Scripps Research Institute in La Jolla. "Everything I've seen about the Thai trial suggests that it doesn't have a prayer." The experiment is funded by the National Institutes of Health and the Pentagon and is being carried out by the Thai government.
December 1, 2008 / SFI Postdoctoral Fellow Elhanan Borenstein and SFI Resident Professor David Krakauer developed a computational model which successfully illustrates the genotype-phenotype relationships in development and evolution. The model relates how a genetic input determines the phenotypic output. It also describes the phenotypic diversity across phylogeny.
