パーチェス法を用いたエージェントシミュレーションによる金融機関の合併に関するシステミックリスクへの影響分析

リーマンショック以降，欧州を中心にインターバンクネットワーク上の金融機関のシステミックリスクに対して関心が高まっている．本研究では，金融機関の破綻の影響がインターバンクネットワークにおいてどのように伝播するかについてエージェントベースシミュレーションを用いて分析した．シミュレーションでは，(1)市場性資産価格の下落率と(2)有価証券に与える損害率を変化させる2種類のシナリオを用意し，金融機関の合併の有効性・破綻リスクのモデル化を試みた．その結果，(1)金融機関の合併を実施した場合においても，多数行にわたる破綻のリスクは削減できない，(2)短期間で有価証券に損害が発生した場合，長期間にわたって損害が発生する状況よりもシステミックリスクが大きくなることが明らかになった．The aim of the present study is to evaluate systemic risks by manipulating the declining rate of marketable asset price and damaging of securities due to merger of financial institutions. An agent-based simulation platform with purchase method of international accounting standard is developed and analyse the influence of the goodwill (Noren), produced by merging financial institutions. The research revealed the following two points: (1) merger of financial institutions cannot prevent the failures of many banks; (2) systemic risk is more increasing damaging of securities than declining rate of marketable asset price

ウェルビーイング志向の価値共創とその分析視点

The purpose of this paper is to propose viewpoints for analysing well-being oriented value co-creation. We firstly explain the concept of transformative service research: TSR which centres on consumer well-being in service and discuss its importance in serviceology as well as service marketing. Based on the systematic literature review, this paper divided into four categories of TSR studies by using two axes of “resource scarcity and resource development” and “micro and meso-macro”. We analysed two Japanese transformative service cases which include capability development in both micro and meso-macro level as the final value of service, thereby proposing additional perspectives for analysing about the resource integration for well-being oriented value co-creation

社会的養護の変化動向と支援体制の在り方 ― 社会的養護制度の再編に向けて ―

The role of child protection is changing in a societal change. The purpose of this research is to examine the ideal method of carrying out support system based on the change situation of Japan’s the system of child protection.

The role of the care for an abused child is expected in recent years. And the importance to support of home rehabilitation is increasing. It was shown that the system of child protection is tinged with the character of family support. When examining the ideal method of carrying out support system, it is a subject in future what kind of therapeutic care is offered to the child who has abuse experience

DEAとInverted DEAのノンパラメトリック検定を用いたわが国の電力各社の生産性に対する電力自由化の効果検証

This paper is verifying of the effects on the electric power deregulation in Japan to the productivity of each electric power company by using the parametric and nonparametric test of the DEA (Data Envelopment Analysis) and the Inverted DEA (Inverted Data Envelopment Analysis). In this paper, the first step of the evaluation of the relative efficiencies and inefficiencies of each electric power company for a total of 21 years before and after electric power deregulation. The second step of the verification of the effects on the electric power deregulation in Japan to the productivity of each electric power company by using the parametric and nonparametric test of the DEA and the Inverted DEA are clarified. The verification of the effects on the electric power deregulation of the productivity of each electric power company was identified statistically
