Sociopsychological Analysis of Japanese Industrial Policy: The Sumitomo Metals Incident

Abstract:  In the 1960s, the former Japanese Ministry of International Trade and Industry (MITI) controlled key industries through its industrial policy. It is commonly believed that this policy was based on an economic rationale. In particular, the MITI justified what are known as recession cartels on the grounds that reducing production volume would prevent destructive competition. Our purpose is to go beyond this current economic understanding via a sociopsychological analysis. We focus on the so-called Sumitomo Metals incident of 1965 when the Sumitomo Metals Company refused to follow the MITI guideline demanding a reduction in steel production. This was the first such incident in which a private company explicitly refused to abide by MITI administrative guidance. We hold that the industrial policy was not necessarily based on an economic rationale. Sumitomo was alone enjoying profit while all other companies were suffering loss. The MITI and major steel manufacturers insisted, without economically sound reasoning, that Sumitomo should reduce its steel exports. On an economic basis, however, steel exports should have been promoted, not restricted, to counterbalance the domestic recession. The whole incident was a sociopsychological battle disguised as an economic debate, and the economic argument of the MITI and other steel manufacturers was actually an elaborate scheme of psychological rationalization. Their severe denouncement of Sumitomo is best explained by the psychological defense mechanisms of projection and displacement. Furthermore, the recession cartel in this case was essentially a ritual of collective suffering under the orchestration of state authority.     

A preliminary study on quantitative relations among growth, reproduction and mortality in fishes

Summary As a quantitative approach to the life histories of fishes, the present paper attempted to predict a relation among reproduction, growth and mortality numerically with a technique of control theory, the discrete maximum principle. A method for predicting the relation was derived on the postulate that natural selection maximized the net reproductive rate subject to a few constraints. The derived method was applied to Atlantic cod and Atlantic herring populations in the Southern Gulf of St. Lawrence as numerical examples. The examples demonstrated that the theoretical reproductive effort and body weight were well consistent with the observed ones every age but the theoretical survival rates were slightly different from the observed ones. For the reasons mentioned below, however, it should be interpreted that the examples rather support the adopted postulate to a certain degree. First, in general, it is very difficult to obtain good estimates of the rates with traditional methods. Second, intense fishing pressure possibly changes the life history parameters to some extent in fish populations. Moreover, the examples also suggested that, to examine the postulate in further detail, similar analyses had to be made with the data of many fish populations on which intense fishing pressure had not been exerted.

Marital Status and Self-Rated Health in Rural Inhabitants in Japan: A Cross-Sectional Study

Poor self-rated health is considered to be a predictor of short survival, and self-rated health is associated with several lifestyle and sociodemographic factors. To determine whether marital status is an independent risk factor for poor self-rated health among inhabitants in rural areas, we conducted a cross-sectional survey of inhabitants in Japan. Complete responses were obtained from 10,268 individuals. Self-ratings of mental health, demographics, and symptoms were used to predict self-rated health. Being male; having disease, questionnaire-based physical complaints, and depressive state; having lower levels of education; and being divorced resulted in higher odds (95% confidence interval) for poor self-rated health, presenting 1.41 (1.18–1.69), 10.8 (8.62–13.7), 1.11 (1.09–1.12), 1.11 (1.08–1.13), 1.22 (1.02–1.46), and 1.53 (1.01–2.31), respectively. In contrast, age, friendship, and other marital status such as single or bereaved showed no significant relationship with poor self-rated health. To improve self-rated health among rural inhabitants, attention should be focused on divorced inhabitants, especially men.     

Resource exploitation of larvae ofGastrophysa atrocyanea Motschulsky andgalerucella vittaticollis Baly (Coleoptera: Chrisomelidae) under a limited resource condition

Summary Resource exploitation by and intraspecific competition in larvae ofGastrophysa atrocyanea andGalerucella vittaticollis were investigated in field and laboratory experiments. Larvae of both species frequently suffered from food shortages in the field. WhenG. atrocyanea larvae suffered from a food shortage, severe intraspecific competition occurred because of lack of predation and parasitism. This exploitive competition was caused by a local food shortage of the host plant. Individuals survived by fast exploitation when food became abundant (contest type competition). TheG. atrocyanea larvae were wasteful of the food resource, and no mechanism by which to economize on the utilization of the resource was acquired because of their exploitation of the abundant resource. In contrast, theG. vittaticollis population probably is regulated by extrinsic factors such as predation and parasitism. Those larvae grew into smaller adults than those ofG. atrocyanea under a food shortage, so that their wasted food consumption was lower than that ofG. atrocyanea. Although intraspecific competition was similar to that forG. atrocyanea, it was not as severe. The food forG. vittaticollis was apt to be appropriated by other wasteful exploitators such asG. atrocyanea, which was superior in resource exploitation; thereforeG. vittaticollis frequently suffered a food shortage. Consequently selection in relation to tolerance to starvation became more acute forG. vittaticollis than forG. atrocyanea, and individuals ofG. vittaticollis that could endure starvation better may have been selected.     

Population dynamics of the green leafhopper,Nephotettix virescens Distant (Hemiptera: Cicadellidae) in synchronized and staggered transplanting areas of paddy fileds in Indonesia

Summary The population dynamics ofNephotettix virescens, a vector of rice tungro virus disease was investigated in a synchronized transplanting area at Jatisari (1984–1986), West Java and in a staggered transplanting area at Sidan (1986–1988), Bali, Indonesia. The FARMCOP suction sampler was employed for population censuses ofN. virescens and its natural enemies. The population growth pattern was affected by transplanting pattern: In the staggered transplanting area, the population density increased from the immigrant generation to the first generation, and sharply decrease thereafter, while in the synchronized transplanting area the population density often reached the highest peak in the second generation. The degree of contageousness in the spatial distribution ofN. virescens was negatively correlated with population density of the immigrant generation.

Measuring Information Behavior: A Time Budget Survey in Japan

This paper discusses the results of a time budget survey which was conducted nationwide in Japan in 1995 on ‘information behavior’, that is, the amount of time people spent communicating and using information media ranging from conversations to computers. We propose a three-dimensional time budget survey as a method for measuring information behavior in actual life. The method classifies information behavior into 24 categories and measures them with respect to three factors, i.e. time, location and purpose of behavior. Our survey revealed that the total time spent on information behavior was about seven hours per day, of which about 45% was spent watching TV. The displacement effect of PC use on TV watching was estimated by a “time-shift matching” design. The results demonstrated that use of a PC does not significantly affect TV viewing, despite a large difference in TV viewing time between PC users and non-users.

Income earning opportunity and work performance affect donating behavior: Evidence from dictator game experiments

Using dictator game experiments, the authors investigate the effect on donation of the dictator and/or recipient working prior to the dictator donating. We focus on two issues that previous studies have not considered. First, we examine the impact on donating behavior of a difference in endowment caused by the dictator's work performance. Second, we explore donation behavior when the recipient's work does not yield income or affect the dictator's endowment, but the recipient's work performance is made known to the dictator. Experimental results indicate that donating behavior is affected not only by the dictator working, but also by the recipient working. In addition, donating behavior is affected by income level, as determined by the dictator's work performance, and is influenced by the recipient's work performance, two findings not previously reported.     

A new destructive Poisson odd log-logistic generalized half-normal cure rate model

We propose a new cure rate survival model by assuming that the initial number of competing causes of the event of interest follows a Poisson distribution and the time to event has the odd log-logistic generalized half-normal distribution. This survival model describes a realistic interpretation for the biological mechanism of the event of interest. We estimate the model parameters using maximum likelihood. For different sample sizes, various simulation scenarios are performed. We propose the diagnostics and residual analysis to verify the model assumptions. The potentiality of the new cure rate model is illustrated by means of a real data.
