In dieser Dissertation erfolgt eine Analyse des Schutzes von Biodiversität durch Payments for Environmental Services (PES) und, insbesondere im empirischen Teil, innerhalb des Ansatzes Reducing Emissions from Deforestation and Forest Degradation plus (REDDplus). Die Anwendung von PES-Programmen zum Schutz von Biodiversität gewinnt im umweltpolitischen Bereich immer mehr an Bedeutung. Gleichzeitig ist die Umsetzung solcher Schutzprogramme jedoch mit erheblichen Transaktionskosten und damit der Gefahr von Ineffizienzen verbunden. Die Möglichkeit der Bündelung von Biodiversität mit einer weiteren Ökosystemleistung, hier der Speicherung von Kohlenstoffdioxid, wird hinsichtlich der Wirkungen auf die Schutzniveaus beider Ökosystemleistungen und der Veränderung der Produktionsweise des landwirtschaftlichen Sektors in einem monopsonistischen Modelansatz analysiert. Durch die formale Analyse zeigt sich, dass für einen effizienteren Schutz der beiden Ökosystemleistungen economies of scope bei den Transaktionskosten mit der Bündelung von PES-Programmen realisiert werden müssen. Ein Beispiel für die praktische Umsetzung von Payments for Environmental Services ist der REDDplus-Ansatz. Das Ziel ist die Reduzierung von Treibhausgasemissionen durch den Erhalt und die nachhaltige Bewirtschaftung von tropischen Wäldern, aber auch der Schutz von Biodiversität. Innerhalb des empirischen Teiles der Dissertation wird untersucht, inwiefern es durch die Verfolgung beider Ziele zur Realisierung von economies of scope bei den Transaktionskosten kommt. In die Analyse werden sechs Länder (Costa-Rica, Indonesien, Mexiko, Kambodscha, Peru und Vietnam) einbezogen. Die Analyse erfolgt auf der Grundlage von Szenarien, welche mit Hilfe der Readiness Proposals der Länder für den Zeitraum von 2008 bis 2030 erstellt wurden. Anhand der Ergebnisse kann gezeigt werden, dass es nicht automatisch durch die Zusammenlegung von PES-Programmen zu einer Realisierung von economies of scope kommt. Eine Bündelung solcher Programme ist daher nicht in allen Phasen ihrer Umsetzung ratsam. / This thesis conducts an analysis of conservation of biodiversity through Payments for Environmental Services (PES) and, particularly in the empirical part, within the approach of Reducing Emissions from Deforestation and Forest Degradation plus (REDDplus). In the field of environmental policy the use of PES programs to conserve biodiversity becomes increasingly important. At the same time the implementation of such programs is associated with significant transaction costs and the risk of inefficiency. The possibility of pooling biodiversity with other ecosystem services, here carbon sequestration, is analyzed in a monopsonistic model with regard to the effects on the level of conservation of both ecosystem services and the change in the production process of the agricultural sector. The results of the formal analysis pointed out that economies of scope must be realized in transaction costs for an efficient conservation of both ecosystem services. The REDDplus approach is an example of the practical implementation of Payments for Environmental Services. The target of this approach is the reduction of greenhouse gas emissions through preservation and sustainable management of tropical forests, but also the conservation of biodiversity. The empirical part of the thesis examines the possibility of realizing economies of scope in transaction costs if both targets are pursued. The analysis includes six REDDplus countries (Costa Rica, Indonesia, Mexico, Cambodia, Peru and Vietnam). The analysis is performed on the basis of scenarios that have been created using the Readiness Proposals of countries for the period from 2008 to 2030.The results show that merging PES programs does not automatically ensure a realization of economies of scope. A bundling of such programs is not advisable at all stages of implementation.

This study is to explore the future development of Bank of Kaohsiung (BOK), the only Kaohsiung based medium-size banking institute. Due to the close relationship between banking and economic development, banking institutes with headquarter at Kaohsiung serving the local enterprises in this region play a significant role. While¡Amost of the local banking institutions in Kaohsiung area moved their headquarters to Taipei or have been merged by Finance holding companies owing to their poor performance. BOK is the only one left. Nevertheless, BOK should not be satisfied with the advantage of being the only medium-size local bank, but has to seek the way to withhold the advantage from the market and survive even better when facing the severe competition from giant Finance holding companies. This research adopts the questionnaire research method of case study and carries on the research by exploring: 1.the viewpoint of the middle-ranked clerks of BOK for the value of the Bank¡¦s operation core resources. 2.the viewpoint of the bank clerks of BOK for their intention and cooperative willingness in the bank development, including bank organizational change and economies of scope. The conclusions of this study are presented as follows: 1.Most of the middle-ranked clerks of BOK agree to the view points of resource-based view that ability is more important than resources , intangible resources is more important than physical resources and finance resources. 2.42.5% of bank clerks agree that it is a major defect of BOK with most of their branch office located at the southern part of Taiwan. Over 70% of bank clerks agree to move of the poor performance branch office to other volatile city. However, 84.5% of the questionnaires insist that any assignment to serve in other area shall be volunteered. 3.Developing the wealth management business is mild positive to bank clerks of BOK, and young, new coming, high educated bank clerks are more optimism. Over 80% of bank clerks recognize that solid customer support is the great asset of their Bank. 4.Expanding the loaning business among the medium and small enterprises is mild positive to bank clerks of BOK, especially high educated young bank clerks. 5.Nearly half of bank clerks believe that there is a little chance that BOK will not become a financial holding company. Also, 42% of the employee reject or highly reject the Bank to carry out actively to merge with other financial holding company. This research attempts to make some contributions on this subject. We start from the viewpoint of the middle-ranked clerks and bank clerks of BOK, through the empirical questionnaire research. We hope this can provides an objective discussion platform for people who concern the future development of BOK in the relevant issues.

O monocultivo, delineamento da produção agropecuária mais tradicional, desde a Revolução Verde, têm sido relacionado ao desequilíbrio ambiental de ecossistemas, e escassez de recursos naturais. Neste contexto, sistemas integração lavoura-pecuária (ILP) tem se mostrado promissores em relação à benefícios ambientais e produtivos, quando comparada a sistemas de monocultivo. Existe, todavia, poucos trabalhos que abordam os benefícios econômicos potenciais dos sistemas ILP. O objetivo desta dissertação foi desenvolver análise econômica e financeira da produção de milho grão e bovinos de corte em sistemas de monocultivo e ILP. A primeira etapa para o desenvolvimento da pesquisa foi a coleta de dados do projeto intitulado Impacto ambiental, produtividade e viabilidade econômica de sistemas de monocultivo e integrado de lavoura pecuária, financiado pela Fapesp (Processo Nº 2014/24514-6) delineado a partir de seis tratamentos experimentais: T1) Monocultivo de milho grão; T2) Monocultivo Brachiaria brizantha cv. Marandu; T3) Integração entre milho e Brachiaria brizantha cv. Marandu, semeados simultaneamente; T4) Integração entre milho e Brachiaria brizantha cv. Marandu, semeados simultaneamente, com aplicação de herbicida; T5) Integração entre milho e Brachiaria brizantha cv. Marandu, tendo sido o capim semeado na adubação de cobertura do milho; T6) Integração entre milho e Brachiaria brizantha cv. Marandu, semeados simultaneamente, na linha e entrelinha do milho, com aplicação de herbicida. A segunda etapa foi a cálculo dos custos variáveis dos tratamentos experimentais. A terceira etapa consistiu no cálculo do custo total de produção de sistemas de produção representativos comerciais, que replicassem os manejos e tecnologias utilizados nos tratamentos experimentais. A quarta etapa consistiu na análise financeira, tendo sido o valor presente líquido (VPL), a taxa interna de retorno (TIR) e o PayBack os indicadores de tomada de decisão. O software Microsoft Excel® foi utilizado para o cálculo dos custos de produção, construção do fluxos de caixa e estimativa dos indicadores de viabilidade. Os resultados indicaram ganhos econômicos da ILP, em relação ao monocultivo, explicados pela teoria da economia de escopo. As fontes da economia de escopo identificadas nessa pesquisa foram: diluição de custos fixos e complementariedades técnicas compartilhadas. Os custos de produção unitários da lavoura e da pecuária foram menores na ILP do que nos sistemas de monocultivo. Os sistemas ILP e o monocultivo de milho grão foram considerados economicamente viáveis, com base no VPL, TIR e PayBack. O VPL do sistema ILP foi maior do que do sistema de monocultivo de milho, o que demonstrou outro benefício econômico dos sistemas integrados, se comparados ao monocultivo. A pecuária monocultivo foi economicamente inviável, baseado nos mesmos indicadores de viabilidade econômica. / Monoculture farming, the traditional agriculture approach since the Green Revolution, has been associated with the environmental imbalance of ecosystems and with the scarcity of natural resources. Within this context, integrated crop-livestock (ICL) systems have shown to be promising in terms of environmental and productive benefits when compared to monoculture systems. However, few studies have addressed the potential economic benefits of ICL systems. The objective of this dissertation was to perform an economic and financial analysis of corn grain and beef cattle production in monoculture and ICL systems. The first phase of the study consisted of the collection of data from the project entitled Environmental impact, productivity and economic viability of monoculture and integrated crop-livestock systems, financed by Fapesp (2014/24514-6) and designed in six experimental treatments: T1) corn monoculture; T2) Palisade grass (Brachiaria brizantha cv. Marandu) monoculture; T3) corn plus Palisade Grass sown simultaneously; T4) corn plus Palisade Grass sown simultaneously plus herbicide; T5) Palisade grass sown at topdressing corn; T6) Palisade Grass sown at the line and inter-line of corn. In the second phase, the variable costs of the experimental treatments were calculated. The third phase consisted of calculating the total production cost of representative commercial production systems that replicate the managements and technologies used in the experimental treatments. The fourth phase consisted of financial analysis using the net present value (NPV), internal rate of return (IRR), and payback as indicators for decision making. The Microsoft Office Excel software was used for the calculation of production costs, cash flow definition, and estimation of viability indicators. The results indicated economic gains of the ICL system compared to monoculture, explained by the theory of economies of scope. The sources of economies of scope identified in this study were the dilution of fixed costs and shared technical complementarities (fertilizers for example). The unit production costs of livestock and crop were lower in the ICL than in the monoculture system. The ICL systems and corn grain monoculture were considered economically viable based on NPV, IRR, and PayBack. The NPV of ICL systems was bigger than the NPV of corn grain monoculture, which has shown another economic benefit of the integrated systems compared to monoculture. The livestock monoculture system proved to be economically unviable because of the negative NPV and IRR below the minimum attractive rate considered.

The EU has been promoting unbundling of the transmission grid from other stages of the electricity supply chain with the aim of fostering competition in the upstream stage of electricity generation. At presence, ownership unbundling is the predominant form of unbundling in Europe. However, the benefits of increased competition from ownership unbundling of the transmission grid may come at the cost of lost vertical synergies between the formerly integrated stages of electricity supply. The policy debate generally neglects such potential costs of unbundling, yet concentrates on its benefits. Therefore European crosscountry evidence may shed some light on this issue. This study helps fill this void by empirically estimating the magnitude of economies of vertical integration (EVI) between electricity generation and transmission based on a quadratic cost function. For this purpose we employ novel firm-level panel data of major European electricity utilities. Our results confirm the presence of substantial EVI, which put the policy measure of transmission ownership unbundling into question.

本研究採用Translog多產品成本函數與要素份額方程式，組成一個二要素投入(勞動與其他支出)與二產出(經紀業務與其他收益業務)之聯立估計模型，利用1999年至2003年共五年度108家資料齊全之專營期貨商混合橫斷面與時間序列資料，運用實證方法採用近似無關迴歸估模型，以反覆近似無關迴歸估計方式，估計台灣專營期貨商成本函數之參數估計值，並進一步計算出射線與產品別規模經濟指標與多樣化經濟指標，來探討台灣專營期貨商整體產業及個別業務之規模與多樣化經濟。 實證結果發現，在規模經濟方面，射線與產品別規模經濟指標之估計值均具有1%的統計顯著性，且皆小於1，表示台灣專營期貨商無論是整體產出或個別產出均具有規模經濟的特性，此隱含台灣專營期貨商享有規模經濟，亦即平均成本將隨產出之增加而有逐漸下降的趨勢。再進一步對台灣專營期貨商經營規模大小來作分析，其結果發現：無論是射線規模經濟值或各產品別規模經濟值均與台灣專營期貨商之規模大小無明顯的關聯。而在多樣化經濟方面，經紀業務與其他收益業務兩項業務具有弱成本互補性，因此，經紀業務與其他收益業務兩項業務間具有多樣化經濟之特性。 根據上述實證結果，針對主管機關、台灣期貨交易所及期貨業者，本研究分別提出相關建議如下： 一、主管機關：主管機關應在許可的範圍下，考量市場風險管理，逐步 放寬國內外法人進行期貨交易之相關限制（如僅能從事避險交易 等），並參考國外期貨市場交易與發展經驗，使台灣專營期貨商 之業務種類及範圍能夠進一步擴大，促使產出更為多元，進一步擴 大整體市場規模。 二、台灣期貨交易所：隨著金融國際化的腳步，如何使台灣期貨交易所 所推出之商品成為全球交易的標的，並藉以協助台灣專營期貨商開 拓全球化市場，擴大其經紀業務及其他收益之產出水準（如受託買 賣、交易顧問、財務操作收益等）及整體市場規模，乃為台灣期貨 交易所的一項重要課題。 三、期貨業者：由於台灣專營期貨商在經紀業務和其他收益業務間具有 多樣化經濟之特性，所以，期貨業者在經紀業務手續費不斷下降的 狀況下，應可藉由發展期貨顧問業務，提供高附加價值的期貨交易 服務，吸引期貨交易人至該期貨商從事期貨交易，並提升受託結算 客戶比重，藉以擴大產出水準，獲取最大的利潤。

Much of industry is seeking scope economies, but this requires more complex and flexible product realisation. Modelling technologies have potential to support the life cycle engineering of both Economies of Scope and Scale (EoSS) manufacturing systems. However when companies operate in dynamic environments it is not sufficient to model manufacturing systems in isolation. Rather a holistic modelling methodology is needed which can create structural and behavioural models of dependencies between the manufacturing systems, and the business and engineering environments in which they operate; so that a suitable balance between economies of scope and scale can be achieved. This thesis describes the conception and development of a step wised Extended Modelling Methodology (EMM) which facilitates reasoning, and related decision making, about EoSS manufacturing systems. The EMM was conceived from exploratory research in two SMEs, following which it was applied and case tested in a large manufacturing company. Little academic attention to date has been paid to theorising about the link between ‘Economies of Scope and Scale (EoSS) phenomenon' and ‘manufacturing systems design'. Hence many questions about EoSS manufacturing remain unanswered, such as: (1) academic communities need to know what EoSS actually means and how state-of-the-art modelling can support qualitative and quantitative analysis of EoSS system phenomenon; and (2) industry needs to know how they can benefit from EoSS, what attended costs they might incur, and what best balance between scope and scale economies can be achieved. With these general requirements in mind the thesis reports on the conception and industrial application of the EMM. This has: (A) developed new ideas about EoSS, which can be used to characterise EoSS phenomenon; (B) introduced a new way of visualising architectural aspects of EoSS at multiple-levels of abstraction; and (C) with reference to case studies has illustrated the use of multi-level modelling to enable predictions to be made about EoSS benefits and costs.

本文將設定一 Translog 多產品成本函數模型，以估計台灣旅行業之規模 經濟 (Economies of Scale) 及多樣化經濟 (Economies of Scope)程度 。在 Translog 多產品成本函數模型中，係以廠商所經營之四項業務，包 括來華觀光、出國旅遊、國民旅遊及代辦業務等，當作四種不同的產品， 而要素投入則為勞動與資本租賃。實證結果顯示，台灣旅行業普遍存在規 模經濟的現象。此結果可能導致：第一，所謂``靠行''的形成；第二，規 模較小的廠商可能根據本身的競爭優勢與經營特色而採取市場區隔化策略 ，以服務某特定之顧客群；第三，現有旅行業廠商之間的合併，或是來自 產業外的廠商藉購併進入旅行業市場，以從事多角化經營。另外，就產品 生產效率而言，我們以多樣化經濟存在與否認為，來華觀光與出國觀光之 間、來華觀光與國民旅遊之間，以及出國觀光與國民旅遊之間，因其業務 關聯性不大，而無法發揮資源共用共享的效果，因此不適合聯合生產。而 出國觀光與代辦業務之間，因業務關聯性大，因此若能聯合生產，則必然 能夠產生綜效。至於來華觀光與代辦業務之間，以及國民旅遊與代辦業務 之間，雖無明顯之證據顯示其具有聯合生產之優勢，但若存在閒置產能， 或是因某種業務之專業性不高，致使人力資源之轉換成本不大時，亦不排 除聯合生產之可能。

This thesis explores the bilateral shipping and trade between Finland and Sweden during the post-war period. It comprises five articles and one introductory chapter for which the common point of departure is the growth and transformation of bilateral trade and shipping. The first two articles analyse the structural change of bilateral trade from a national and regional perspective. The three following articles provide an overview and analysis of the ferry shipping. By integrating the perspective in these articles in the introductory chapter and by providing a long historical record, the change of economic relations between Finland and Sweden in the post-war period is discerned. This thesis applies an economic historical approach and is founded on various fields of social science. The issue of trade is analysed within the framework of conventional and new trade theory, and the analysis of ferry shipping is governed by economic and geographic theories. The studies on trade shows that the transformation of production seen in Finland and Sweden meant that the trade increasingly became dependent on an exchange of products arising from matching industries. In turn the foreign trade arising from the Northern part of Finland and Sweden was still dominated by so called inter-industry trade. In addition to these results, the studies of ferry services shows that the growth of vehicles and passengers conveyance, together with the expanded onboard services, also intensified the commercial exchange. Due of the multi-output structure, the ferry service efficiently met the growing demand of travel and trade. The main conclusion of this thesis is that the convergence of incomes and economic structure had a significant impact on bilateral trade and ferry shipping. In addition the process of economic integration, technological advances together with specific policies issued on shipping also contributed to strengthen the economic ties between Finland and Sweden.
