Technological revolutions and speculative finance: evidence from the British Bicycle Mania
研究了1895-1900年英国自行车狂热中股价暴涨暴跌的现象，发现基本面或风险变化无法完全解释，支持技术革命、高短期利润和宽松货币导致投机脱钩的假说。
Technological revolutions are often accompanied by substantial stock price reversals, but previous literature has produced competing explanations for why this is the case. This paper brings new evidence to this debate using data from the innovation-driven British Bicycle Mania of 1895–1900, in which cycle share prices rose by over 200% before collapsing by more than 75%. These price patterns are not fully explained by fundamentals or by changes in the nature of risk associated with cycle shares. Instead, the evidence from the Bicycle Mania supports the hypothesis of Perez (2009), who argues that new technology, high short-term profits and loose monetary conditions increase the level of speculative investment, ‘decoupling’ share prices from fundamentals.
