In this study, we have constructed a trading market of ideas. Using this market, we have conducted an experiment. First, in the form of answers to a given problem, the subjects submit ideas. Next, the market organizer picks some good ideas to be listed on the stock exchange. Lastly, the subjects buy or sell the securities of those ideas. By market mechanism, the prices change depending on the quality and the needs of those ideas. Through financial incentives, market mechanism reduces the influence from others upon one's decision-making. It also makes one tell the truth. Based on the findings of this experiment, this paper summarizes the issues to be aware of, when building a market of ideas in organizations and firms.

Affiliate Advertising is a type of advertising in social media, which empower consumers to insert advertising. Thus we can call it Consumer Generated Advertising Media. We conducted Web-based surveys for bloggers including affiliates and for blog readers including ones who have bought from any affiliate. By analyzing the data, we found a paradox that affiliates are more reluctant to reveal profiles of affiliates than others while it is effective to promote purchases. Based on these findings, we discuss the possibility of advertising in social media.

IT investment portfolio model proposed in this study consists of three portfolios: IT strategy, IT infrastructure, and IT engagement portfolios. The best balance among the three portfolios determines a success of the portfolio management. By utilizing this model, a company can define an IT investment portfolio in the light of alignment with business strategy and foundation for execution, coordination among different organizational layers, and IT investment risk.

Proposed is the foundation of a first-person perspective systems analysis (1ppSA) that utilizes Activity Theory (AT) as diagrammatic resources and phenomenology as a meta-methodology. We exemplify the usefulness of 1ppSA by showing some examples of practicing phenomenological reduction. As mentioned by sociologists, if we can become aware of them, we are liberated from conditions and structures, thereby can have more capabilities of innovations and collaboration for better organizations and information systems. By artificially replacing conditions and structures that we are usually unconscious of by the use of each element of AT diagrams, we can appreciate consistencies and conflicts among the conditions and structures. This means doing eidetic reduction, which results in becoming aware of the conditions and structures.

These days, many organizations have been paying increased attention to evaluation system to change the behavior of the workers. According to an official survey, about 20% organizations point out that “the result of evaluation cannot be accepted by workers" is a problem. In the research of equity, individuals compare the ratio of their outcome to input with others'. Recently various types of indices are commonly used in evaluation systems. This partly implies that the reason why the result of evaluation is hardly accepted lies in the difficulty of knowing others input. We focus on the difficulty of knowing others input, and analyze the effect of evaluation system on equity and organizational performance by using agent-based-social-simulation.

There are some research reports that promoting taking holidays with pay gives a positive impact on the economic system. The rate of holidays with pay taken by Japanese employees is remarkably lower than that in Europe and US. One reason of such a low rate in Japan is due to the working environment as organizational culture. We need to consider individual situations of organizations for exploring promotion policies of holidays with pay. In this study, using an agent-based model where agents select their actions based on the norm of the organization, we conduct simulation to examine the effectiveness of the policies for planned holidays with pay in different situations.

As consumers have been becoming to get a lot of information through social networking services such as “Twitter" and “Facebook", the elucidation of consumer behavior considering the effect of social networking service is required. The purposes of this study are (i) to elucidate the impact of social networks on consumer behavior and (ii) to demonstrate the effective way of advertising. We construct a consumer behavior model considering the effect of social networks with movie market by using multi-agent model. Simulation results show that the impact of social networks on diffusion process varies according to the characteristic of movies. Furthermore we demonstrate the effective time-series allocation of advertising budget in appropriate to the characteristic of movies.
