Amateur creations are one source of Japan’s competitiveness in the content industry. This study summarizes prior research on amateur manga (comic), called doujinshi, in terms of its history and current status, overseas trends, gender aspects, and copyrights. This study then develops a research model with three hypotheses on the relationship between creation and monetization across multiple content categories. To test these hypotheses, an online survey of 2,593 individuals was conducted on the creation and monetization of manga and music. The survey’s findings were as follows: (1) Consumers who create works in one content category tend to do so in other categories. (2) Consumers who monetize their own work in one content category tend to do so in other categories. (3) Consumers who create works in multiple content categories tend to monetize their own works. This study also shows the current status of creation and monetization in Japanese manga and music.

The relationship between innovation and consumption among internet users is not uniform. This research shows different relationships between innovation and consumption in terms of the level of involvement in music from an internet survey of 1,000 music users. We measure the level of involvement in music using the two levels of components of involvement suggested by Lastovicka and Gardner (1979). For the analysis, we divide the samples into the “high involvement” and “low involvement” groups and examine each group for their relationship between innovation, indicated by “making one's own music and posting one's songs or performances on the internet,” and consumption, indicated by “average amount of money spent on music downloads per year.” The results show that there are heterogeneous characteristics among high and low levels of involvement groups in the aspects of consumption and innovation behavior. In the low involvement group, users actively innovating are also actively consuming. However, in the high involvement group, there is no clear relationship between innovation and consumption. To put it concretely, the consumption per innovating user is approximately four times more than that of non-innovating users in the low involvement group, but it is about the same in the high involvement group. In addition, the consumption per innovating user in the low involvement group is approximately two times more than that of innovating users in the high involvement group.

This study examines how the performance of startups during the time period up to their initial public offering (IPO) is affected by the macro environment, a topic that has not been given much consideration to date. Taking the end of 2012 (the beginning of Abenomics), when Japan’s economic environment shifted to a hot market, as the transition point, we analyzed companies that did IPOs in terms of such variables as the target market, the attributes of the companies in the sample (type of entrepreneurship), and the date of their actual establishment. We found that for those companies operating in an economically favorable environment, the average time period from startup to IPO was relatively long. This could be because an economically favorable environment and improved business conditions spurred startups that had been implementing a wait-and-see attitude. We have some reservations about using “time to IPO” naively as a performance indicator, and caution should be exercised when using it.

When a market grows and matures so that its product becomes commoditized, we can usually expect product prices to decline due to price competition. However, in the digital camera market, although prices started to decline after they first went on sale, camera prices then began to rise. This was not because mass consumers shifted from the low-priced segment to the high-priced segment. Prices went up across all segments of the market. (A) In the low-priced segment, companies making low-priced products exited the market, and the remaining companies raised their prices by focusing on higher-quality products. (B) In the higher-priced segment, the number of major makers started declining, and prices steadily rose because products priced close to the highest-class products were released into the market. (C) In the mid-priced segment, two types of companies entered the market: companies in the low-priced segment that had developed higher-quality products and companies in the high-priced segment that added mid-priced products as alternatives.
