| Title Alternative | A Note on Exchange Rate Dynamics of a Small Country Exposed to the Global Business Cycle |

| Abstract | 本稿では，開放マクロ経済学でよく利用される Mundell-Fleming モデルの動学版を２つの方向に拡張し，そこから得られる為替レートの変動を調べる。第１の拡張は，定常状態での局所的な Marshall-Lerner 条件を維持しつつ，大域的にはそれが満たされない状況を定式化することである。より詳しく言うと，通常の定常状態の近傍では小国である自国の通貨の減価は純輸出を増加させるが，為替レートがその範囲を超えると，逆に自国通貨の減価が純輸出を減少させるという状況である。第２の拡張は，大国である外国，あるいは世界経済，が持続的かつ周期的な景気循環に曝されている状況をモデルに組み入れることである。このような設定のもとで，為替レートが自国通貨高均衡と自国通貨安均衡のそれぞれの周囲を経巡るような複雑な変動を生じることを計算機による数値計算により観察する。 |

| Title Alternative | For further improvements of the short-term homestay programme |
| FullText URL | 41_3_001_017.pdf |
| Author | Hirota, Yoko| Oka, Masumi| |
| Abstract | In 2001, Advisor's Room in International Centre, Okayama University, initiated the short-term (one day or overnight) homestay programme. The aim of this paper is to improve the implementation process of the programme by reviewing the homestay between 2001 and 2008, especially focusing on the period 2004 – 2008 based on the survey of hosts and international students participating in the programme. A total of 133 students (a response rate 95%) and 136 hosts (a response rate 97%) responded to the survey. The findings show a fairly high level of student satisfaction with the programme and a good level of communication between hosts and students. The survey results also suggest some problems identified in earlier studies by Hirota & Oka have been resolved. However, 25 percent of the students surveyed still did not write thank you notes to their hosts promptly while many hosts expected them to do. In addition, it was revealed that the passive attitude of some students discouraged their hosts from communicating with them. So the coordinator needs to encourage students to be active and make the most of the opportunity, and students’ personalities can be taken into consideration at the time of matching students to hosts. Lastly, the current matching system also needs to be improved because a limited choice of dates undermined the success of the homestay. Under the current system, there are only four choices of dates which the coordinators arrange based on the university's schedule. Consequently several students have to choose a date even though they have something to do on that day and it also takes a long time to find available hosts. The current matching process is based on student's application including their choice of date and hosts choose which student to take in. So an alternative for more effective matching should be considered: hosts provide their information such as possible dates for stay, number of family members, their pets, and so on, and students choose which family to stay with based on their preference and convenience. |

| Title Alternative | Evaluation Method of Total Risk and Additional Private Risk of Investment Project −Investment Criteria for Companies Considering Stakeholders Interest− |
| FullText URL | 41_2_021_038.pdf |
| Author | Koyama, Yasuhiro| |
| Abstract | 機関投資家が資産運用としての証券投資を評価する場合と異なり、企業が事業投資を実施するかどうかの意思決定を行う場合、市場リスクのみをリスクとして評価するのは企業の実情に添わない。たとえば、企業の規模に比較し、取り上げる新規案件の規模が非常に大きく、仮にその案件が失敗した場合に企業自体の存立も危うくなるような場合、市場リスク以外に案件が抱える総リスク（total risk）の評価も重要な意思決定上のポイントとなるであろう。特に主要株主が分散投資していない集中投資家やオーナー経営者である場合、あるいは日本企業のように企業に経営資源をコミットしている経営者や従業員等の利害関係者（stakeholders）の立場も考慮している場合には、事業投資の意思決定を行う際、市場リスク料に追加個別リスクも含めた総リスクを評価して意思決定を行うことが求められるであろう。総リスクに含まれる追加リスク料としては、例えば、企業規模に伴うリスク料、業界別リスク料、カントリー・リスク料等が指摘され、実証的な計数化や検証がなされてきている。リスク評価の方法としては、リスク料をリスクフリー・レートに追加したリスク調整割引率で期待キャッシュフローを割り引いて現価を求める方法と、期待キャッシュフローからリスク額を控除した確実性等価を求め、リスクフリー・レートで割り引いて現価を求める方法がある。前者の方法は「リスク調整割引率法」であり、実務では「Build−up法」や「追加リスクを加えたCAPM 法」が用いられている。後者の方法は「確実性等価法」であり、理論的には前者よりも優れているとされるが、実務ではあまり採用されていないのが実情である。この研究ノートでは、①リスク調整割引率法で割引率に追加する追加リスク料と、確実性等価法で控除される個別リスク額の相互の関係を検討し、案件評価における両手法の互換性を検討した。また、②実務上必要となる、追加個別リスク料の見積もり方についての検討も行った。最後に、③利害関係者を重視した企業の事業投資の意思決定または評価基準についての検討も行った。 |

| Title Alternative | Were Privileges and Restrictions given to Japanese Postal Savings as a Government Enterprise balanced in the 10 years before Privatization? |
| FullText URL | 41_2_001_020.pdf |
| Author | Nishigaki, Narunto| |
| Abstract | The reason why public financial institutions that should tightly regulated have great power and oppress the private sector, which has been significantly deregulated in recent years, is often thought to be that so many privileges are given to public financial institutions as government enterprises. Indeed, we agree that government enterprises have had privileges, but if total size of them is smaller than that of their restrictions as government enterprises, it is difficult to say that they are the main cause of competitive dominance of government enterprises. Nishigaki (2009a) re−estimated sizes of privileges given to Japanese Postal Savings in the 10 years before privatization (1997FY-2006FY), and found that the size as to the accumulated amount of the 10 years was considerably smaller than that in the method of Japanese Bankers Association (2002, 2004), to which Yamori and Nishigaki (2004) had pointed its irrationality and great possibility of overvaluation. This paper firstly estimates sizes of restrictions (such as universal service obligations, social contribution activities, and opportunity costs caused by regulations of investments and businesses) given to Japanese Postal Savings in the same term, and secondly compares the total size with that of privileges in time−series. We will find the facts that, in the first half of the period, the privileges and the restrictions were almost balanced, so that in this regard no evidence can be confirmed that Postal Savings should have been oppressing private banks in Japan, and in the latter half (age of Japan Post), the balance came to be collapsed because of the large reduction of the privileges and of the rapid increase of the opportunity costs, as a result, its social contribution activities had to be reduced sharply. |

| Title Alternative | Study on retirement program of Japanese Companies : Interview for employee's work contribution. |
| FullText URL | 41_1_001_029.pdf |
| Author | Wu, rina| Matsuda, Yoichi| |
| Abstract | This paper examines to what degrees employees' work contribution to Japanese companies is currently reflected in their retirement program, by using interview as research method (July−Dec., 2008 ; on eight companies and two public offices). It also examines the content of the programs, such as social environment surrounding the system, company policies, and problems and solutions involved in the operation, as well as the transition of the system after Meiji era. Major findings include the followings. Firstly despite some changes occurred in the system as a result of diversification of employment types and styles and also alteration of company policies, the system itself will be maintained in the future. Secondly, although many companies modified conventional seniority−based salary systems for a retirement program that reflect employees' work contribution more clearly through an adoption of 'point system' and other measures, they still find some problems in new systems in their operation and practicality. |

| Title Alternative | Note on Gentaro Oe, a JapaneseWorker of the Pacific Northwest Lumbering Industry |
| FullText URL | 40_4_143_157.pdf |
| Author | Kurokawa, Katsutoshi| |
| Abstract | At the mid−1920s, the Japanese exclusion movement by the labor unions, which had been stilled since the late 1910s, resurged in the Pacific Northwest. Disappointedly, many Japanese in the Pacific Northwest lost their respect for the cause of the labor movement of the United States in the late 1920s and 1930s. A few people, however, continued to seek the organization of the Japanese workers and their solidarity with the white labor unions. Gentaro Oe, a Japanese worker of the Pacific Northwest lumbering industry was one of them. There are not many historical documents that mentioned Oe and I can clarify his life and accomplishment very little. He was, however, one of the diligent contributors of the Taihoku Nippo (Great Northern Daily News), one of the vernacular newspapers in Seattle in those days. He gave his comments on the problems concerning the situation of Japanese workers in the lumbering industry of the Pacific Northwest in many articles published in this newspaper. I introduce some of them in this note. From them, it is clear that he was proud of being a sawmill worker in the Pacific Northwest and hoped that the fellow Japanese workers also would respect themselves. For that purpose, he wished the organization of the Japanese workers of the lumbering industry. |

| Title Alternative | Laws and Union-Management Relations : Union-Management Agreements and ‘Cadres’ Issue in the French Metal Industry facing the 35-Hour Working Week |
| FullText URL | 40_4_093_114.pdf |
| Author | Shimizu, Koichi| |
| Abstract | In 1998, the French socialist Government stipulated the first law on the 35-hour working week, which fixed the conditions for a company receiving a reduction in social security payments. That is, the company had to conform working hours to the legal 35 hours a week by concluding a union-management agreement. In this paper, we show the strategies of the French Employers’ Association of the Metal Industry (UIMM) facing such a situation by analysing its agreements concluded with unions. The first issue treats the reaction of the UIMM, which aimed to sidestep the impact of the 35 hours law, but had to make a concession facing the critique coming from the socialist Government. Second, we explain what the French ‘cadres’ are, and the UIMM’s strategy to accord a qualification of the cadre to lower hierarchy of managers for assuring sufficient working hours of these people. This is because the 35-hour working week is not applied to the cadres. Third, we show the modifications of the union-management agreement after the right-wing Government amending the working hours laws, stipulated by the left-wing Government. Showing the dynamic relations between laws and union-management agreements, we can explain the dynamics between the law as a rule of the game and the behavior of the players, i.e. the employers’ association and the unions, as well as the importance of the union-management relations in deciding labor conditions even in the France. |

| Title Alternative | Evaluation Criteria for Investment Project − Comparison between Quadratic Utility Function and Other Methods − |
| FullText URL | 40_4_073_091.pdf |
| Author | Koyama, Yasuhiro| |
| Abstract | The purpose of this article is to clarify the usefulness of quadratic utility function in evaluating investment projects. In the field of corporate finance, the standard technique used to evaluate proposed investment projects is capital asset pricing model and its graphed security market line. According to CAPM, the market risk is the risk to be quantified as risk premium in estimating the cost of equity capital. CAPM assumes that marginal and important investors are well−diversified institutional investors like pension funds, insurance companies and investment funds. To such investors, private risk of each project is negligible, because it is diversifiable. However, many top management in Japan believes that other stakeholders like employee, commercial banks, suppliers and etc are equally important. Their loyalty and contribution to the company is a vital factor to the success of company. Their fate or success becomes dependent on the growth and viability of the company, as they often commit their resource to the company for life or for a long period of time. In this case, Japanese top management should try to maintain and strengthen their long−term sustainability, which is more important than the short−term increase of shareholders wealth. In this context, evaluating proposed investment projects, private as well as market risk should be included with equal importance in calculating the total risk. In this article, I tried to compare such technique as SML (CAPM), Capital Market Line and quadratic utility function and clarified their difference in their evaluation results. CML and quadratic utility function are useful in evaluating private and total risk of investment projects, because their formula, different from other utility functions, contain the standard deviation to represent investment risk. Quadratic utility function seems to be a proper method in evaluating the investment project which involves unique or different type of business risk and requires relatively huge amount of investment. Dealing with utility function, I demonstrated to quantify utility value in terms of absolute amount of money rather than indicating the value in commonly used percentage. This would enable us to compare with the other traditional technique of net present value. |

| Title Alternative | Formative Process of Regional Concentration in a JapaneseWhaling Fishing Ground in the Edo Period : Analysis of the Particularity of the SaikaiWhaling Industry Area |
| FullText URL | 40_4_049_072.pdf |
| Author | Sueta, Tomoki| |
| Abstract | The whaling industry in early modern Japan was the greatest fishery in Edo period. At the time, whaling was mainly conducted in four districts (i.e. Kishu, Tosa, Tyosyu, and Saikai). whaling industry was carried on by large−scaled industrial management object which was called “whaling organization (kujira−gumi)”. I have for my object to make the regional concentration process of the whaling fishing ground in Goto Han clear about a whaling industry in Goto Han who didn’t also aim so much in the Saikai area this time. That was separated 3 periods in an extended period from Enpo and a Genroku period to Bunsei and a Tenpo period here in particular, and a change and the development process of the “whaling organization (kujira−gumi)” in Goto Han were considered, also considering a relation with a financial problem of Goto Han. When saying a whaling industry in Saikai area in the Edo Period up to now, I was very strong in an image of an achievement of Fukazawagumi of Omura han and a big “whaling organization (kujira−gumi)” of 3, Nakao, Doi and Mastomi. On the other hand, activity of the Eguchi family of Arikawa village was learned about in Goto Han, too. But development of the “whaling organization (kujira−gumi)” of the former and the latter has been talked on separately without associating. But, the Saikai area “whaling organization (kujira−gumi)”which can have talked on individual “whaling organization (kujira−gumi)” management and its development process independently respectively up to now was intermingled in a whaling fishing ground of Goto Han actually by this analysis. Moreover it was revealed that habitat segregation was done by a fishing ground as for the latter period in the Edo Period. And when it was considered from a geographical side, regional centralization in a whaling fishing ground in Nishiumi area was seen, and moreover it was revealed that a differentiation phenomenon in a winter fishing ground and a fishing ground in spring has formed. It’s understood to be different from a whaling industry area of 3, other Kishu, Tosa and Nagasu from the thing.In other words, it was being enabled that management activity in fishing ground area of sea of a whaling industry in this Saikai area is formed beyond the Han. Development of a whaling industry management was seen aggressively in the the inter−han whaling industry which is the characteristic of the Saikai whaling industry area here. That led to successive development by the “whaling organization (kujira−gumi)” from formation in the first term in the Edo Period in this whaling industry area to the latter period. Above, the geographical angle as well as the historical science−like angle of the ancient document emphasis were taken in by the main subject. And I made it clear about formative process in a whaling industry area in Japan in the Edo Period when I had almost no studies up to now by that. Moreover the local industry as a large− scale whaling industry and concerning in Han fief were made clear. |

| Abstract | In 1993, Menshikov and Zuev introduced ρ−percolation model, in which a path of a graph is ρ−passable in a bond percolation configuration if the concentration of open bonds on it is at least ρ, and concerning this model, they gave four open problems. In this paper, we answer three problems out of them : the first one is whether the ρ−percolation critical probability is equal to the critical probability corresponding to finite/infinite expectation of the number of ρ−connectable vertices from a fixed vertex, the second is whether the 1-p ercolation critical probability is equal to the Bernoulli bond percolation critical probability, and finally the third is whether the probability of the existence of ρ−passable path of length exceeding n starting from a fixed vertex always decays exponentially in the subcritical phase. |
