Mark Buchanan, a theoretical physicist, is the author, most recently, of “The Social Atom: Why the Rich Get Richer, Cheaters Get Caught and Your Neighbor Usually Looks Like You.” He explains in the NYTimes how physicists are creating models to explain the markets. He offers examples of three models one of which explores how a very small, such as .1%, transaction tax can actually stabilize some markets. The tax slows down speculation, especially in foreign currency markets.
