Price Effects on Compound Commodities

We examine the effect of simultaneous price changes on the total demand for a group of goods, which we call a compound commodity. Specifically, we consider unit and proportional cost components (e.g., taxes, transportation costs) imposed on compound commodities. If the unit cost is positive, then the proportional cost raises the relative price of the more expensive good, and thus induces substitution towards the less expensive good within this group. Then, the substitution effect of the proportional cost for a compound commodity is non‐negative if and only if the compound commodity and the other goods are, on average, not strongly substitutable.     

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.     

The designing of corporate accounting law in Japan after the Second World War

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.     

Competition and termination of the alliances between asymmetric partners: The case of Japanese department stores

To enrich the literature on alliance termination, we recognize that the dynamics of individual alliances are subject to the structural characteristics of the alliance portfolios in which they are embedded. We anchor our study in the context of large industry leaders partnering with multiple small partners, the latter of which can be viewed as competing for access to the formers’ resources. We expect that a small partner’s relative capability in relation to peer partners within a leader’s alliance portfolio is negatively related to the likelihood of alliance termination, since the leader acknowledges that partners with inferior capability do not deserve to be supported. Furthermore, this relationship would be moderated by alliance portfolio size, market overlap with peer partners, and with industry leaders. Using a unique dataset of 145 alliances between leading and small department stores in Japan in the period 1977-93, we found general support for the hypothesized relationships.     

Optimal privatization policy with asymmetry among private firms

We revisit the relationship between the optimal privatization policy and market competition indexes such as the Hirschman–Herfindahl index. It is affected by the number of the firms and asymmetry among the sizes of the firms; the smaller the number of firms and the more asymmetry among firms, the higher the market concentration index. The literature on mixed oligopolies suggested that the optimal degree of privatization increases with the number of private firms, and thus, decreases with the market competition index, assuming that all private firms are homogeneous. We investigate how asymmetry among private firms affects the optimal degree of privatization. We propose the simplest and natural model formulation to discuss asymmetry among private firms. We find that the optimal degree of privatization is either nonmonotone or monotonically increasing, and thus never monotonically decreasing, in asymmetry among private firms.     

Implicit protectionism via state enterprises and technology transfer from foreign enterprises

We formulate a mixed triopoly in which one state enterprise competes with one domestic and one foreign private enterprise. The private enterprise can transfer its technology to the private rival, which reduces the rival’s production cost. We show that if the privatization policy is endogenous, then the foreign firm voluntarily transfers its technology. We also show that the foreign enterprise may strategically raise its local ownership share. These results suggest that the existence of a state enterprise and its potential future privatization serve as an industrial policy that improves the domestic firm’s competitive advantage relative to the foreign enterprise.     

Regional Economic Integration and Article XXIV of the GATT

This paper studies the economic impact of regionalism under the realistic assumptions of constant tariffs and asymmetric bloc formation. As an extension of the Krugman framework, the impact is decomposed into several components, each of which has a clear economic implication. Economic integration definitely worsens outsiders' welfare even if the external tariffs of the bloc are unraised. Bloc members' welfare first increases with the expansion of the bloc; but when about half of the world is united into the bloc, welfare begins to decrease. Simulation results shed some light on the incentive structure of major participants, who face various configurations of regional integration.     

Investigating Collaborative R&D Using Patent Data: The Case Study of Robot Technology in Japan

The growing trend of collaborative R&D initiated by firms has been well documented. However, the evidences regarding basic questions such as the benefits of collaboration and the motives of firms are still mixed. The main novelty of this paper is to investigate these questions by using comprehensive patent data with a focus on information concerning inventors. We consider the case of robot technology in Japan since early 1990s and get the following results. First, collaboration with external research partners lead to a higher quality of the invention. Second, the determinants and motives, which encourage firms to engage in collaborative research, differ depending on the partner they are collaborating with. Copyright © 2011 John Wiley & Sons, Ltd.
