One of those workshops covers an area that has excited me for several years now, The Third Workshop on Prediction Markets. Prediction markets aggregate information quite efficiently in ways we don't yet fully understand and remains a fertile area of study. Legal limitations on betting have restricted the applications of prediction markets, particularly in the US, but that might change soon. The Commodity Futures Trading Commission (CFTC) is asking for public comment for regulations of prediction markets. Their concept release gives a nice discussion of the legal issues. Will this lead to more legitimate real money markets in the US? Time will tell.
