The Substitution Effect of Mobile Games on Console Games: An Empirical Analysis of the Japanese Video Game Industry

In this paper, we discuss the substitution effects between mobile games and console games. We estimate such effects by a fixed-effect regression with instrumental variables using panel data of about 100,000 observations. The results showed that the substitution effects of playing smart devices on 3DS, Wii, and PSP were recognizable, but did not have significant effects on PS3, and the substitution effects on PSP were very small. Therefore, mobile games had a substitution effect on casual console games, or on console games in which the play situation resembled mobile games. In addition, the substitution effects were at most about 0.1. The substitution effects were small. Our results indicate that mobile games represent the pioneers in the new market of gaming at least during our observation period. But new games and traditional games will coexist for a while.     

An alternative approach to community-based ecotourism: a bottom-up locally initiated non-monetised project in Papua New Guinea

Community-based ecotourism (CBET) is presented as a tool for conservation and sustainable development by conservation practitioners and development agencies, but is reported to have achieved little. Several scholars argue that many problems stem from inadequate power relationships between external actors and local communities, leading to low community participation. This study opens a debate on governance and social enterprise in CBET by examining a bottom-up approach to community-based ecotourism based on a small-scale CBET initiative in an amenity-poor remote indigenous community in Papua New Guinea. This initiative is unique in the following aspects: it was initiated by a community member; external assistance was advisory only; no external financial assistance was given; and it has taken place in a non-monetised economy. Participant observation and in-depth interviews with local key informants were used to identify community-defined positive/negative impacts and community participation processes. Overall, there was substantial support for the project; it contributed to community welfare, generated economic benefit, had positive conservation outcomes and from the viewpoint of the community had no adverse cultural impacts. One of the keys for success was the development of a strong community agency that led to high community participation and individual rather than the community ownership.     

A Theory of the Demand for Underwriting

We examine the demand for underwriting and its effect on equilibrium in an insurance market in which insureds know their risk type, but insurers do not. Our analysis indicates that a set of policies including one that requires buyers to take an underwriting test can constitute a full coverage Nash equilibrium when perfect classification is possible. We also find that underwriting equilibria, in which low risks obtain greater coverage than they would without underwriting, widely exist in a Wilsonian market with nonmyopic insurers. Our findings provide a potential explanation for why empirical evidence on adverse selection is mixed.     

Complementarity,fiscal decentralization and economic growth

Theories of the voluntary provision of public goods and development economics have clarified that complementarity in the production process is a crucial ingredient to understanding how alternative economic environments affect economic performance. This paper examines how the structures of intra- and inter-regional complementarity affect the relationship between economic growth and fiscal decentralization. We provide a theory that describes how fiscal decentralization affects economic growth under various structures of regional complementarity. Our empirical analysis, based on a panel data set of the fifty states of the United States over the period of 1992–1997, supports our theoretical specification of the production function. Also, we observe a hump-shaped relationship between fiscal decentralization and economic growth that is consistent with our theoretical result. Our analysis also shows that the optimal degree of fiscal decentralization conducive to economic growth is higher than the average of the data in some cases, and hence further decentralization is recommended for economic growth. The previous version of the paper was presented at the 59th Congress of the International Institute of Public Finance (University of Economics in Prague, Prague), the 2003 Fall Meeting of the Japanese Economic Association (Meiji University, Tokyo), the 60th Annual Meeting of the Japanese Institute of Public Finance (Kansai University, Osaka), and in seminars at Yokohama National University and the University of California, Irvine.

PACIFIC RIM TRADE AND DEVELOPMENT: HISTORICAL ENVIRONMENT AND FUTURE PROSPECTS

Pacific Asia is deep rooted in its cultural heritage and historical background, which have set the tone for regions success. These same factors also have created rather different trading practices, compared with those of the West — practices that are less transparent and full of hidden private trade barriers.
Interdependence within the region suggests integration, but Pacific Asia has taken a course of non-exclusive cooperation rather than following the exclusive course of the European Community (EC) and of the North American Free Trade Agreement (NAFTA). The latter two trade blocs threaten the continued success and development of Pacific Asia. Although the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) sends relief, fostering a cooperative rather than a retaliative Asian Pacific Economic Cooperation (APEC) organization offers the most promise.
