Futures market may help predict bird-flu chances

first_imgATLANTA – Think bird flu will become a worldwide threat this summer? Wanna put some money on that? In an unusual effort to better predict the advance of a potential flu pandemic, public health experts will be staked about $100 apiece to bet on the spread of bird flu. This type of grim futures market has also been created to predict hurricanes and temporarily, a few years ago, terrorist attacks. In this case, the goal is to develop a faster way to collect expert opinion about the potential spread of a deadly disease outbreak. “Farmers have used futures markets for decades to make decisions about what crops to plant. We’re just borrowing that concept to help people in public health and health care make decisions about the future,” said Dr. Phil Polgreen, a University of Iowa assistant professor of medicine who helped create the project. It’s being funded by the Robert Wood Johnson Foundation, which is donating nearly $250,000 to the effort. The University of Iowa, which set up futures exercises for hurricane predictions, box office receipts and presidential elections, will operate the bird flu enterprise. Organizers hope to recruit at least 100 epidemiologists, veterinarians and other medical experts from around the world for the two-year project. They will be asked to join an online trading system akin to agricultural futures markets, in which an investor buys contracts that businesses will be able to deliver certain volumes of, say, corn or pork bellies. But in this project, the contracts represent not the likelihood of a good corn harvest but the odds that deadly bird flu will infect a human in Hong Kong by July 1. “Yes” contracts on that prediction are currently trading at 43 cents. That means the experts think there’s a 43 percent chance of that occurring. At issue is the deadly H5N1 strain of bird flu, which has killed 167 people in 10 countries since 2003, but so far hasn’t been easily spread from person to person. Health officials fear that it will mutate into a highly contagious form that could kill millions worldwide. Health officials have been closely monitoring reports of human and animal infections, but what will happen next is a matter of assorted speculations. Since 1988 the University of Iowa has operated a project called the Iowa Electronic Markets (IEM), which aggregates predictions to forecast major events. Much of the focus has been elections, and the Iowa markets have generally outperformed political polls. A predictive market for seasonal flu, operated in Iowa and North Carolina, correctly predicted the current level of flu activity in an area 71 percent of the time, even though the predictions were made before any solid surveillance reports. The market had a 50 percent success rate at predicting flu activity a week in advance, according to a recent report in the journal Clinical Infectious Diseases. Such markets have sometimes proved controversial. In 2003, the Pentagon dropped plans for a futures market that would have allowed traders to profit from accurate predictions on terrorism, assassinations and other events in the Middle East. Some lawmakers attacked the idea as immoral; U.S. Sen. Tom Daschle of South Dakota described it as a “plan to trade in death.” Organizers predicted that the bird flu market should prove less controversial, and the New Jersey-based Robert Wood Johnson Foundation cautiously agreed. “It might be considered controversial if it’s not well understood,” said the philanthropy’s Robert Hughes. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
