Power laws and market crashes Empirical laws on bursting bubbles
In this paper, we quantitatively investigate the statistical properties of a statistical ensemble of stock prices. We selected 1200 stocks traded on the Tokyo Stock Exchange, and formed a statistical ensemble of daily stock prices for each trading day in the 3-year period from January 4, 1999 to December 28, 2001, corresponding to the period of the forming of the internet bubble in Japn, and it...
متن کاملPower Laws of Wealth, Market Order Volumes and Market Returns
Using the Generalised Lotka Volterra (GLV) model adapted to deal with muti agent systems we can investigate economic systems from a general viewpoint and obtain generic features common to most economies. Assuming only weak generic assumptions on capital dynamics, we are able to obtain very specific predictions for the distribution of social wealth. First, we show that in a ’fair’ market, the we...
متن کاملBubbles and Market Crashes
We present a dynamical theory of asset price bubbles that exhibits the appearance of bubbles and their subsequent crashes. We show that when speculative trends dominate over fundamental beliefs, bubbles form, leading to the growth of asset prices away from their fundamental value. This growth makes the system increasingly susceptible to any exogenous shock, thus eventually precipitating a crash...
متن کاملLiquidity and Market Crashes
In this paper, we develop an equilibrium model for stock market liquidity and its impact on asset prices when participation in the market is costly. We show that, even when agents’ trading needs are perfectly matched, costly participation prevents them from synchronizing their trades, which gives rise to the endogenous need for liquidity. Moreover, the endogenous liquidity need, when it occurs,...
متن کاملShakeouts and Market Crashes
Stock-market crashes tend to follow run-ups in prices. These episodes look like bubbles that gradually inflate and then suddenly burst. We show that such bubbles can form in a Zeira-Rob type of model in which demand size is uncertain. Two conditions are sufficient for this to happen: A declining hazard rate in the prior distribution over market size and a positively sloped supply of capital to ...
