On statistical inference on the mean-variance efficient set

A proof of the asymptotic distribution of the estimated mean-variance frontier is given. A Bayesian prediction interval is derived for the capital asset pricing model. Numerical illustrations show that the prediction intervals for the CAPM are smaller than those for the constant mean model, if the fit of the CAPM is better than that of the constant mean model.     

Customer behavior analysis using motion pictures： Research on attractive flier design method

In this report, the authors would like to propose CMP-FDM （Customer Motion Pictures-Flier Design Method） to increase the willingness of consumers to visit the automobile dealership. CMP-FDM is a method of creating attractive fliers while using customer behavior analysis with videos. According to the analysis of how customers see fliers, the authors classify their behavior into three types and create attractive designs so that each guarantees each customer＇s satisfaction. Finally, the authors integrate the three types of fliers into one attractive to all customers by organizing the design features （design elements）, and then validate the method.     

How does environmental performance affect financial performance? Evidence from Japanese manufacturing firms

This paper examines the effects of environmental performance on financial performance using the data of Japanese manufacturing firms from 2004 to 2008. As the environmental performance, our study considers the two different environmental issues of waste and greenhouse gas emissions in capturing the effects of corporate environmental management on financial performance. In addition, to clarify how each financial performance responds to a firm's effort in dealing with different environmental issues, we utilize many financial performance indices reflecting various market evaluations. Our estimation results show the different effects of each environmental performance on financial performance. Waste emissions do not generally have significant effects on financial performance. On the other hand, greenhouse gas reduction leads to an increase in financial performance in the whole sample and clean industries, although it does not have significant effects on financial performance in dirty industries. Furthermore, as the firm growth rate increases, the partial effects of waste emissions on financial performance decrease, whereas the partial effects of greenhouse gas emissions on financial performance increase.     

The moral–emotional foundations of political discourse: a comparative analysis of the speech records of the U.S. and the Japanese legislatures

There is a growing body of research that focuses on the supposedly close association between an individual’s moral–emotional behavior and his/her political ideology. A prominent example is Haidt’s “moral psychology,” which claims that political liberals and conservatives draw on mutually different sets of moral foundations. However, this and other arguments, which have mostly been advanced in the social context of the United States, lack a comparative perspective. In this study, we examine these arguments in broader spatio-temporal settings by way of a comparative analysis of public deliberations in the U.S. and Japanese legislatures. More specifically, with the help of well-established moral- and emotional-word dictionaries, and employing advanced computational techniques for systematic data collection, we analyze a large volume of speech data that records floor debates over decades in the U.S. Congress and the Japanese Diet to derive longitudinal moral–emotional dynamics. We then use multilevel modeling to regress the derived moral–emotional patterns of legislative deliberations in each country on various covariates to locate possible drivers of these patterns. The results of these analyses reveal more qualified relationships between a moral–emotional framework and political ideology than preceding arguments have suggested, casting serious doubt on the widespread tendency in the literature to quickly rely on an ideological explanation. The findings suggest the need for a more comprehensive approach to handling moral–emotional phenomena in political science.     

A bayesian analysis of a random coefficient model in a simple keynesian system

The marginal propensity to consume in a simple Keynesian model is treated as a random coefficient. This gives rise to the problem of quotient of random variables, i.e., the Fieller-Creasy problem. The Bayesian and maximum likelihood estimators are compared in sampling experiments. The Bayesian estimators have smaller mean squared errors than the maximum likelihood estimators. Marginal posterior probability density functions for a given sample are also presented.     

Japanese–American Joint Restructuring of National Steel Corporation

In 1984, NKK corporation, a leading Japanese steel maker, acquired from the National Intergroup Inc. (NII), an American holding company, its 50% equity interest in National Steel Corporation (NSC), the fourth largest integrated steel firm in the US. In spite of the US economic recovery that began in 1992, NSC continued to operate in deficit and in June 1994 NKK brought in a new management team consisting of six American executives and one Japanese executive. Since the third quarter of 1994, NSC has turned its financial performance around. In this paper, using Bayesian estimation procedures, we estimate the join point or the time at which the productivity of NSC's major production lines experienced an upward shift; if the join point occurs after an appropriate gestation period of the new management team, NSC's recovery may be said to be due to the efforts by the new management team. After confirming that indeed this is the case, we discuss how the management team achieved the turnaround. The organization of the paper is as follows. The next section presents the background. In the third section Bayesian procedures for estimating a join point are presented. In the fourth section we discuss restructuring at NSC and the Japanese Total Quality Control system. Conclusions are given in the final section. © 1997 John Wiley & Sons, Ltd.
