Bonswanger (economics, the University of Applied Sciences, Switzerland) sheds new light on the role of speculative bubbles in the stock market and argues that bubbles may have a positive effect. He refutes arguments that bubbles increase instability, and contends that bubbles may provide additional investment opportunities with the potential to increase aggregate profits. He demonstrates that highly sophisticated financial systems are needed in order to allow for positive effects to develop, and examines recent experience in Asia where destabilizing effects of bubbles outweighed potential benefits.
