| Outline of Final Research Achievements |
This research explores stock bubble in an asymmetric information environment. We consider two uncertainties, uncertainty of the asset value and the existence of informed traders. Our model has three types of market participants: a market maker, informed traders, and noise traders. The market maker updates his asset value belief through transactions. There are two types of markets, one with informed traders and one without. The market maker does not know which the market is. The market maker also updates his belief about the existence of informed traders through transactions. We find that when informed traders actually do not exist, the asset price systematically deviates from its fair value causing asset bubble. However, after the market maker sufficiently updates his belief, he adequately finds the non-existence of informed traders. Our model contributes alternative explanation about stock bubble process. We also confirm this process using numerical simulations and experiments.
