Resumen de Introducing the random wolf of Wall Street
Financial booms and busts occur when traders all rush to purchase or sell stock just because others around them are, says Alessandro Pluchino of the University of Catania, Italy. Pluchino and his colleagues wondered whether it was possible to stop this cascade of copycat behavior by introducing a random element--traders who ignore all available information and instead buy or sell with equal probability. They found that increased numbers of coin-flipping investors reduced the size and frequency of extreme financial events. In the real world, Pluchino says central banks could take on the role of random traders to calm markets.
