Relationship between Managerial Compensation and Business Performance in Japan: New Evidence Using Micro Data*

This paper examines the relationship between the level of managerial compensation and the quality of corporate governance in Japan in the period following the bubble burst of 1991–1995. There are three main findings. First, Japanese firms with weaker governance have greater agency problems in that managerial opportunism extracts higher compensation and the firm performs relatively worse. Second, these agency problems were more severe during the recessionary period of 1994–1995. Finally, governance structures in industries with higher managerial compensation are relatively weaker than in other industries.     

Business process semi-automation based on business model management

It is important to respond to customers' requirements more rapidly than ever before due to the recent trend in e-business and its technologies. In order to achieve an agile response, we have to manage business models, to reflect the changes in the models and to develop or modify IT systems for further chances. This paper proposes a management framework of layered enterprise models. The proposed framework consists of a business model repository and a software repository, and defines three different grain sizes of modeling layers, namely business modeling, business process modeling and business application modeling, in order to support business modeling and application development. This framework helps us to develop business application in incremental deployment of analysis, design, and implementation to execute business processes. We have implemented a prototype environment using Java. Each repository's contents are described using XML so that the repositories are interoperable. Copyright © 2003 John Wiley & Sons, Ltd.     

On the Role of Monetary Policy in a Deflationary Economy: The Case of Japan

In this paper we review the role of monetary policy for a country facing deflationary pressure based on the recent experience of the Japanese economy. We discuss economic background of inflation policy in Japan and analyze the impacts of the policy. We made simple calculations regarding how much the debt of selected companies and government can be reduced by mild inflation. Noting that the Fisher effect does not work perfectly under liquidity traps, the effect of inflation on debt issue appears quite large. To maintain controllable stable inflation, inflation targeting is a good candidate for the policy rule. J. Japan. Int. Econ., December 2000, 14(4), pp. 238–260.

An Emergency Evacuation Planning Model Using the Universally Quickest Flow

In recent years, catastrophic disasters by massive earthquakes have been increasing in the world, and disaster management is required more than ever. In the case of disasters such as tsunamis, a slight delay in evacuation may deprive evacuees of life. In this article, we formalize the emergency evacuation planning model for evacuation from tsunamis and other disasters based on the idea of the universally quickest flow. We show that there does not always exist a universally quickest flow when the capacity constraint of refuges is taken into account. Therefore, we propose an alternative criterion that approximates a universally quickest flow, and presents an algorithm for finding an optimal flow for this criterion. Numerical experiments are carried out for the evacuation of a local city in Japan where tsunami damages are assumed to occur when a large earthquake occurs in the ocean nearby.     

Dynamic Investment Strategy with Factor Models Under Regime Switches

A model for dynamic investment strategy is developed where assets’ returns are represented by multiple factors. In a mean–variance framework with factor models under regime switches, we derive a semi-analytic solution for the optimal portfolio with transaction costs. Due to the existence of transaction costs, the optimal portfolio is characterized as a linear combination of current and target portfolios, the latter of which maximizes the value function in the current regime. For some special cases of interest, we also derive simplified analytical solutions. To see the effect of regime switches, the proposed model is applied to US equity market in which small minus big and high minus low are employed as factors. Investment strategy based on our model demonstrates empirically that the regime switching models exhibit superior performance over the single regime model for such performance measures as realized utility and Sharpe ratio which are of particular interest in practice. Taking a close look at the time series of portfolio returns, the result shows the usefulness of the regime switching model as investors flexibly optimize asset allocations depending on the state of the market.     

Securing basic well-being for all

The purpose of this article is to examine the possibility of a social choice rule to implement a social policy for “securing basic well-being for all.” The article introduces a new scheme of social choice, called a social relation function (SRF), which associates a reflexive and transitive binary relation over a set of social policies to each profile of individual well-being appraisals and each profile of group evaluations. As part of the domains of SRFs, the available class of group evaluations is constrained by three conditions. Furthermore, the non-negative response (NR) and the weak Pareto condition (WP) are introduced. NR demands giving priority to group evaluation, while treating the groups as formally equal relative to each other. WP requires treating impartially the well-being appraisals of all individuals. In conclusion, this article shows that under some reasonable assumptions, there exists an SRF that satisfies NR and WP.     

MNC's competitive strategies,experiences, and staffing policies for foreign affiliates

This study investigates the relationship between the strategic role of a multinational corporation's (MNC) foreign affiliates and its international staffing policy. Specifically, this study examines how an MNC's decision on expatriation is affected by strategic roles assigned to foreign affiliates: global integration of activities versus local market seeking. An empirical study is conducted using a sample of 808 foreign affiliates of Japanese firms. The research findings suggest that strategic roles of foreign affiliates alone may not adequately explain the international staffing policies of Japanese MNCs. Rather, we found a significant moderating effect of international as well as host country experience on staffing practices for foreign affiliates. While the staffing policies of MNCs striving for improving global efficiency of their operation are moderated by both international and host country experience, those seeking a specific local market position are influenced only by host country experience.     

Extracting the commercialization gap between science and technology — Case study of a solar cell

In this paper, we compared structures of the citation network of scientific publications with those of patents, and discussed the differences between them. A case study was performed in a solar cell to develop a method of detecting gaps between science and technology. Scientific research has tended to be more basic, especially in terms of cell design, whereas patents have focused on more applied technology used in solar cell modules. Of the major citation clusters of scientific publications, only two, namely silicon and compound solar cells, corresponded semantically with patent clusters. Conversely, there were no patent clusters corresponding to the other two scientific research fronts, namely dye-sensitized and polymer solar cells. These research areas could be regarded as opportunities for industrial commercialization because scientific activities exist but not technological applications. Our results could offer an intellectual basis for discovering potential opportunities for industrial commercialization.     

RESOURCE ALLOCATION AND EFFICIENCY OF SHARECROPPING UNDER UNCERTAINTY*

The paper examines how efficiency of sharecropping under uncertainty can be tested empirically. It demonstrates even under uncertainty, equality of factor ratios between sharecropped land and owner-cultivated land supports the hypothesis that the terms of share contracts are effectively enforced by landlords, so as to achieve socially optimum resource allocation and risk sharing, unless the direct elasticities of substitution are identically equal to one. It also provides evidence, that the comparative yield tests conducted in different parts of South and Southeast Asia support the efficiency view of sharecropping.     

The Kigyo Keiretsu Organization and Opportunism in the Japanese Automobile Manufacturing Industry

This paper contends that the distinguishing feature of the subcontracting system for the manufacture and distribution of auto-parts in the Japanese automobile manufacturing industry can be explained by the opportunism hypothesis of transaction cost theory. Opportunism may arise when the parts-supplier uses its information advantage to obtain more favorable contract terms with the manufacturer. It is argued that in response to this kind of informational opportunism, the automobile manufacturer institutes a special form of vertical arrangement, called the kigyo keiretsu group. The kigyo keiretsu group consist of an association of vertically related parts-makers held together by a high degree of sales and technological interdependence, by partial stock ownership, by interlocking boards of directors and by long-term contract. This study raises the possibility of mitigating opportunism among the kigyo keiretsu group firms throughout the core automaker's shareholdings of its parts-supplier.
