The nature of asset price bubbles
A steep and sustained price rise and then its precipitous collapse, both unrelated to the asset's properties - that is the pattern of events which has characterised hundreds of episodes from the "South Sea Bubble" of the 17th century to the housing bubbles of the early 21st century. There is no objective way of assessing the truth of any of the various explanations that have been advanced for them. Their "information cascade" component has been observed in other contexts [1], and the "herding" behaviour that they exhibit has characterised the conduct of the subjects of many experimental studies of human behaviour[2]. A surge in share prices has been termed "irrational exuberance"[3]
