We have developed several agent-based models to analyze microscopic and macroscopic links between investor behaviors and price fluctuations in a financial market. The models are characterized by the methodology that analyzes the relations among micro-level decision making rules of the agents and macro-level social behaviors via computer simulations. In this chapter, we report the outline of recent results of our analysis. From the extensive analyses, we have found that (1) investors’ overconfidence behaviors plays various roles in a financial market, (2) overconfident investors emerge in a bottom-up fashion in the market, (3) they contribute to the efficient trades in the market, which adequately reflects fundamental values, (4) the passive investment strategy is valid in a realistic efficient market, however, it could have bad influences such as instability of market and...

In the asset management in finance task domain, although there exist various text data like accounting settlement or analysts’ reports, few research and development have been conducted. In this paper, we will explore the feasibility to extract valuable knowledge for asset management

As a result of intensive experiments in the market, we made the following findings: (1) fundamental indexing works as effectively as price indexing in the market when market prices reflect fundamental values; (2) fundamental indexing contributes to market efficiency.

In this research, we apply Business Game method to financial education. Especially we focused on learning of asset allocation. As a result of intensive experiments, we found that (1) players learned not to take excessive risk through business game and

In this paper, we discuss the effects of passive investment strategies and asset fluctuation phenomena using our agent-based simulator. Main results include that (1) passive investment is usually effective ...

Although the Passive Investment Strategy is an effective way in efficient markets, Behavioral Finance points out that markets aren’t always efficient. We build a virtual financial market which consists of a thousand investors and allows them to trade two types of assets:

We build a virtual financial market that contains two types of investors: fundamentalists and non-fundamentalists. As a result of intensive experiments in the market, we find that (1) the traded price agrees with the fundamental value and the fundamentalists survive according to the principle of natural selection in the case that the market contains the same number of fundamentalists and trend predictors (investors who make trend prediction), (2) the traded price largely deviates from the fundamental value and the non-fundamentalists frequently obtain excess returns and therefore the fundamentalists are eliminated according to the principle of natural selection in the case that the proportion of trend predictors is extremely high or in the case that the investment ratio of the risk asset is restricted, and (3) the traded price ...

In this research, we apply business game method to financial education. Especially we focused on learning of asset allocation. As a result of intensive experiments, we found that (1) players learned not to take excessive risk through business gaming and (2) they recognize the importance of risk control by our experiments. These findings indicate that our approach is valid for financial education.
