Bounded Rationality in Economics: A Game Theorist's View

In this paper, we argue that it is essential to incorporate bounded rationality into game theory. Game theory has been applied to aspects of economics such as industrial organizati on on the basis of the naive interpret ation of game theory, which requires players to be ideally rational in an extremely unrealistic way. We stress the importance of establishing the perceptive interpretation of game theory by taking boundedly rational players' inductive reasoning processes into account. We explain my recent work, Matsushima (1997), which shows that the subjective games perceived by players in the long run are entirely different from the true objective game, and are trivial games in the sense that there exists a strictly dominant and subjectively Pareto-efficient strategy profile among the set of pure strategy profiles.

Mixed oligopoly and spatial agglomeration

Abstract We investigate a mixed market where a state‐owned welfare‐maximizing public firm competes against profit‐maximizing private firms. We use a circular city model with quantity‐setting competition. In contrast to a pure market case discussed by Pal (1998a) , spatial agglomeration of private firms always appears in equilibrium. All private firms locate at the same point, and the public firm locates at the opposite side. We also find that this equilibrium pattern of the location is second best provided that output of each private firm cannot be controlled by the social planner. JEL Classification: H42, L13
Oligopole mixte et agglomération spatiale Les auteurs examinent un marché mixte où une entreprise publique possédée par l'État et cherchant à maximiser le niveau de bien‐être est en concurrence avec des entreprises privées qui cherchent à maximiser leurs profits. On utilise un modèle de cité circulaire où la concurrence se fait en choisissant la quantité produite. En contraste avec le cas du marché parfait discuté par Pal (1998a), l'agglomération spatiale des entreprises privées paraît être en équilibre. Toutes les entreprises privées se localisent au même point, et l'entreprise publique se localise du côté opposé. Il appert que ce pattern d'équilibre de localisation est un équilibre de second ordre compte tenu du fait que la production de chaque entreprise privée ne peut être contrôlée par le planificateur social.     

An analysis of geographical agglomeration and modularized industrial networks in a regional cluster: A case study at Yamagata prefecture in Japan

In a regional innovation system, a dense inter-organizational network within the region is recognized as a key factor in enhancing knowledge diffusion, regional learning, and effective resource transfers. Therefore, understanding the network structure and physical proximity of organizations is essential. In this paper, we investigated the industrial structure of Yamagata prefecture in Japan as a case study. Because Yamagata is a representative industrial region, the analysis can also provide an insight into other industrial regions. Initially, we investigated the geographical dispersion of firms and found them to be agglomerated along Route 13 and the Tohoku Shinkansen railroad, indicating that infrastructures for transportation still have a decisive role in terms of site location. Subsequently, we analyzed the modular structure of the inter-firm network. The results showed that hub firms construct a different type of network and play different roles within the inter-firm network, reflecting their strategic choice. The results also showed that there is a tendency for firms to transact with those in close proximity, and that firm location is also affected by the location of the hub firm in the module in addition to the infrastructures.     

Current accounts of Japanese airports

The paper examines the current account of 41 major airports. When we exclude depreciation costs, only seven airports are profitable. When depreciation is excluded, only three airports are making profits. Airports managed by local governments are very difficult to sustain financially without subsidies. Airports with more than 5.2 million passengers are profitable when depreciation is taken into account, however most local airports have fewer than 2.5 million passengers. When depreciation costs are excluded, airports need at least 2.7 million passengers to be viable.     

Founders' experiences for startups' fast break-even

While some previous studies have found that the role of founders' collective experiences is paramount in resolving problems inherent in startups, others have failed to substantiate this. This study claims that this incongruence is attributable to a failure to consider organizational processes in which founders' experiences translate into organizational assets through information distribution and interpretation. Using the data from the Panel Study of Entrepreneurial Dynamics, this study demonstrates that startups reach their break-even point faster when their founders have had work experience in the same industry, and that this effect becomes stronger when these firms commit more resources to information distribution and interpretation.     

Profit-enhancing competitive pressure in vertically related industries

Under a simple Cournot model with vertical relations, when downstream firms engage in process R&D, the profits of input suppliers for which upstream competition exists may be larger than those in which each input supplier has a bilateral monopoly relation with its buyer (downstream firm). This is because upstream competition leads to higher levels of investment by the downstream firms. Furthermore, we incorporate the decisions of downstream firms to acquire the ability to procure input from potential outside suppliers, which has the effect of placing competitive pressure on existing input suppliers. We show that no downstream firm acquires such an ability to procure its input from potential outside suppliers in some cases although the acquisition could benefit the input suppliers.     

财政联邦制、产业政策与丰田公司在中国的“南北分治”

"南北分治"是丰田公司进入中国市场后投资活动的结果,也是丰田公司在其海外直接投资中绝无仅有的现象.这一现象是由中国向市场经济过渡中的经济体制衍生出来的.这一现象产生的制度环境以及政策因素,是中国地方政府之间的竞争使丰田公司有激励做出"南北分治"这一帕累托非效率的行动选择,由此产生的效率损失则可以通过地方政府为引进外资而采取的一系列优惠政策所带来的超额利润弥补.     

Integrating business modeling and roadmapping methods - The Innovation Support Technology (IST) approach

The purpose of this paper is to report the integration studies of business modeling and roadmapping methods for the “Innovation Support Technology (IST)” and the IST's practical application to real-world cases. The IST is conducted for the purpose of offering a convenient tool for engineers and researchers in order to enhance corporate value from R&D outputs. “Japan's lost decade” has forced companies to change R&D management and R&D operation style, especially regional industries. We propose the framework for revitalization of regional industries by using the Strategic Technology Roadmap made by the Ministry of Economy, Trade and Industry (METI-TRM) with business modeling. We applied this IST method to several real-world cases to show its effectiveness. This study represents the result of over four years (fall 2002) of work with the value creation framework of the business modeling method for R&D outputs, done by a group of researchers from JATES (Japan Techno-Economics Society).     

Dynamic analysis of innovation and international transfer of technology through licensing

This paper develops a quality-ladder type dynamic general equilibrium model with endogenous innovation and technology licensing as a major source of international technology transfer in developing countries. Examining the dynamic characteristics of the model fully, we explore the short- and long-run effects of both an improvement in the probability of reaching a licensing agreement with a given effort and an increase in the license fee rate. The model shows that the former promotes innovation and technology transfers in both the long and short run, while the latter discourages them.     

Uncertainty of voters' preferences and differentiation in a runoff system

Haan and Volkerink (Haan, M., Volkerink, B., 2001. A runoff system restores the principle of minimum differentiation. European Journal of Political Economy 17, 157-162, this journal) show that the principle of minimum differentiation holds in two-round elections for any number of candidates. We show that the principle of minimum differentiation may not hold, when uncertainty of the position of the median voter is introduced.
