"One can define a bubble as a persistent increase in the price of an asset over and above its fundamental value with an abrupt fall in prices when no buyers are available to make purchases. The occurrence of market bubbles has a long history, starting with the Dutch Tulip Mania (1624-1637) to the South Sea and Mississippi Bubble (1716-1720), the British Railway Mania (1840´s) to the crash of 1929. Recent events have been the crash of 1987, the dot-com bubble (1990s) to the most recent housing crisis in early 2000. Even though bubbles, and a subsequent crash, may reallocate resources to more efficient activities, the economic costs of bubbles are large and sometimes felt for long periods of time."
