气泡破裂作为干扰相变
Bubble burst as jamming phase transition
摘要：
近年来，关于泡沫及其破裂的研究引起了经济学、物理学等各个领域研究者的极大兴趣。经济学家一直认为泡沫是一种价格紊乱。然而，这种研究策略忽略了交易量的重要性。在本文中，我们提出了一个泡沫破裂模型，通过集中的交易纳入一个交通模型，代表自发的交通堵塞。通过对美国房地产市场数据的比较，我们发现泡沫破裂现象与交通拥堵现象有许多相似之处。我们的研究结果表明，交易可能是一个驱动力的爆裂现象。
英文摘要：
Recently research on bubble and its burst attract much interest of researchers in various field such as economics and physics. Economists have been regarding bubble as a disorder in prices. However, this research strategy has overlooked an importance of the volume of transactions. In this paper, we have proposed a bubble burst model by focusing the transactions incorporating a traffic model that represents spontaneous traffic jam. We find that the phenomenon of bubble burst shares many similar properties with traffic jam formation by comparing data taken from US housing market. Our result suggests that the transaction could be a driving force of bursting phenomenon.
