Corporate Restructuring in Japan Part I: Can M‐Form Organization Manage Diverse Businesses?

The purpose of this paper is to examine the recent organizational restructuring in Japan in the framework of organizational economics, assuming that the product/market portfolio of the firm is fixed. How does a firm set about organizing its internal divisions? I first summarize some stylized facts on corporate diversification strategy and multi‐divisional (M‐form) organization in large Japanese firms from different perspectives. I then analyse the problem of choosing an organizational form. In particular, I argue that, precisely because of its related diversification, the multi‐business Japanese firm adopting the M‐form finds it difficult to differentiate its diverse businesses internally.     

Monopoly,product differentiation and economic welfare

This paper discusses the pricing behavior of a monopolistic producer supplying several quality-differentiated goods by using a model of a Lancasterian characteristic approach with consumer's taste pattern dispersed. It examines how finer product differentiation, which is made by the producer by means of the introduction of a new good, changes the price structure and consumer's welfare. It will be establised that the entry of a new good imposes quite different impacts on the price of the goods of higher quality and on those of lower-quality goods.     

Recovery Process Model for Two Companies

The quantification of the recovery rate for the debt of the defaulted small company is one of the most important problems for banks and their supervisors. However, the data of the real recovery rates is seldom available for academic study. Therefore, there have been a few studies for the recovery rate for the debt. The recovery process model for a single company is introduced by Itoh (Asia Pac Financ Mark 2008). In this paper, we extend the model of Itoh (Asia Pac Financ Mark 2008) to two defaulted companies, and we model the recovery processes using an inhomogeneous bivariate compound Poisson process with the delays. In other word, we assume that the recoveries are occurred by the shocks, and that there are individual shocks that affect only one company and common shocks that affect two companies. Moreover, we assume that there are delays between the shock points and the recovery points. Therefore, the recovery points of two companies are correlated, but the recoveries do not occur synchronously almost surely. We derive the correlation of the recovery rates of the debts of two defaulted companies, and the expected value and the standard deviation of the recovery rate for the defaulted debt portfolio. Furthermore, we present two methods based on the Vernic recursion formula and the Monte Calro simulation for calculating the probability distribution function of the recovery process, and illustrate several numerical results.     

ENDOGENIZING CONSUMPTION IN THE INPUT‐OUTPUT MODEL: THEORY AND APPLICATION

Since the basic model of input‐output analysis does not take into consideration the income effect on consumption expenditure, we constructed a model which endogenizes consumption and breaks down integrated production inducement into Leontief and Keynesian effects in a generalized context and in two solution approaches. Using short‐term marginal consumption propensities, we estimated that Keynesian effects make up about 14% of the integrated inducement effects for Japan. The public services sector, which is not influential in the basic model, becomes very influential in consideration of Keynesian effects. Manufacturing and service sector products are the main targets of the expanded consumption. The impact of a change in exogenous final demand can be easily simulated by applying the suggested apparent input coefficient matrix to the integrated inverse matrix.     

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.

结构性困境中的日本经济

日本经济自2002年开始复苏,但复苏的国际环境充满不确定性,同时内部经济仍面临结构性困境。日本从20世纪80年代初起为了减少国家财政赤字而实施的新自由主义政策持续地遭遇失败,未偿公债不减反增,而政府每年的公共支出又很难降下来,加上日本向老龄化社会的快速转化使得福利政策的总体预算很难削减,以致国家财政危机不断加深。另外,劳动者工作条件和社会生活条件的恶化以及人口下降的威胁,使得新自由主义在其框架内难以解决日本面临的结构性问题,因而有必要对于马克思关于资本主义的学说进行再思考。
