摘要翻译:
我们分析了一个在实验室进行的受控价格形成实验,该实验显示了泡沫的证据。我们校准了两个模型,它们以高统计意义证明,由于正反馈,这些实验室气泡有比指数增长更快的趋势。我们发现,正反馈是由交易者根据过去的价格而不是已实现的回报,不断提升对未来回报的过于乐观的预期而运作的。

英文摘要:
We analyze a controlled price formation experiment in the laboratory that shows evidence for bubbles. We calibrate two models that demonstrate with high statistical significance that these laboratory bubbles have a tendency to grow faster than exponential due to positive feedback. We show that the positive feedback operates by traders continuously upgrading their over-optimistic expectations of future returns based on past prices rather than on realized returns.
