[pt] A globalização dos mercados financeiros das últimas décadas trouxe ao centro da discussão de finanças internacionais o conceito de risco-país. A importância do risco para a economia de um país está relacionada ao fato de que, em um ambiente de alta mobilidade de capital, ele acaba sendo um importante balizador da taxa de juros doméstica. Para que se possa compreender a evolução do risco de um país, medido pelo spread de seus títulos no mercado internacional, não basta entender a influência das características específicas dos países, mas é fundamental também avaliar o papel dos choques internacionais. Dentro deste arcabouço, o objetivo central desta dissertação é avaliar de maneira mais precisa o papel das variáveis externas na determinação dos spreads dos países emergentes. Mostraremos que para entender os choques externos sobre os spreads emergentes não basta observar os movimentos da taxa de juros livre de risco, como se supõe na literatura tradicional, mas também é preciso fazer considerações acerca da aversão ao risco dos investidores internacionais, e do contágio entre os países emergentes durante períodos de crise. / [en] The globalization in the financial markets during the last decades brought the concept of country risk to the center of the discussion in international finance. The importance of country risk is related to the fact that, in a high capital mobility environment, it becomes a important determinant of the domestic interest rate. To understand the evolution of the risk of a country, measured by the spread of its bonds in the international markets, it is important not only to comprehend the influence of its specific fundamentals, but also to evaluate the role of the external shocks. In this framework, the central goal of this dissertation is to evaluate more accurately the role of the external variables in the determination of the spreads of the emerging countries. It will be shown that to understand the external shocks it is not enough to observe only the movements of the free risk interest rate, as the traditional literature assume, but it is also necessary to take into account the risk aversion of the international investors, and the contagion between emerging economies during crisis time.

我國自91年4月1日推動「產險市場費率自由化時程計畫」且分三階段實施， 在第一階段允許產險公司「附加費用」自由化，產險公司若簡化行政流程、降低人事成本，就能調降附加費用率。第二階段費率自由化，產險公司除了「附加費用」自由化外，更允許「危險保費」有限度的偏離；也就是說「危險保費」是有條件自由化。自98年4月1日起正式實施第三階段，也就是意味著各產險公司均應在第一階段及第二階段之緩衝時期做好萬全之調適與配套措施，產險業進入全面競爭之時代。 費率自由化第三階段正式的實施，其相關的監理配套措施及內容，遷動著未來汽車保險市場之發展，而汽車保險業務一直都是產險市場的最大宗業務。但在核保、理賠及行銷等方面處處受到車商保代通路的限制、影響，若能進一步在車險通路行銷制度問題上加以改善，對我國未來汽車保險市場將有很大的發展空間。 本篇論文主要目的係探討我國費率自由化相關議題。透過98年4月1日費率自由化第三階段的正式實施，我國產險市場邁入全面自由化階段，除了對費率自由化第三階段的相關監理配套措施內容作深入瞭解外，並針對費率自由化第一、二階段實施過程中所產生的諸多相關議題作深入研究，且借鏡鄰國日本產險費率自由化之經驗作為參考，並搭配我國汽車保險市場的實際現況，提出費率自由化第三階段實施對未來汽車保險市場的預期影響，並藉由個案公司的研究分析，提出個案公司未來車險通路最適行銷策略，以期盼產險業在面臨全面費率自由化之際，提出個人的幾點因應淺見，能提供給產險業者作為參考，並亟盼未來我國汽車保險市場運作能更佳健全蓬勃發展。 / Taiwan’s Non-life Rate Deregulation Plan has put into practice since April 1, 2002 with three phases. The first phase is to liberalize the restrictions of the loading expense. The non-life insurers can flexibly reduce the loading expenses by way of a more simplified administration process and lower personnel costs. The second phase further allows for a limited deviation rate applicable for the risk premium, namely, a conditioned deregulation for the risk premium. The third and last phase begun from Apr. 1, 2009 is to entirely liberalize all relevant expenses and premium rates. It also means that all non-life insurers should have worked out a set of comprehensive measures in preparation for a completely competitive market. The future development of motor insurance, which ranks largest among all lines of business, is subject to the corresponding supervisory measures to be taken at the third stage. However, the agents of motor companies regularly dominate the non-life insurers’ operations in the aspects of underwriting, claim and market strategy. Hence, if the existing problems related to the marketing channels encountered by the non-life insurers can be resolved, a more prosper development for motor insurance market is anticipated. The thesis mainly studies the relevant topics in relation to the rate deregulation in Taiwan. In line with the rate deregulation implemented in the third stage, the thesis not only has an in-depth study of the corresponding supervisory measures, but also discusses many related subject matters arising from the implementation process between the first and second phases. Meanwhile, the expected effects resulting from the third phase has been submitted based on Japanese same experiences in the past and domestic motor insurance market. Furthermore, by means of a specific case study, the thesis also proposes some optimal marketing strategies, which might be helpful to insurers as well as to develop a sound and stable motor insurance market in the future.

Through integrated modeling of power system operations and market risks, this thesis addresses a variety of important issues on market signals modeling, generation capacity scheduling, and electricity forward trading. The first part of the thesis addresses a central problem of transmission investment which is to model market signals for transmission adequacy. The proposed system simulation framework, combined with the stochastic price model, provides a powerful tool for capturing the characteristics of market prices dynamics and evaluating transmission investment. We advocate the use of an AC power flow formulations instead since it allocates transmission losses correctly and reveals the economic incentives of voltage requirements. By incorporating reliability constraints in the market dispatch, the resulting market prices yield incentives for market participants to invest in additional transmission capacity. The second part of the thesis presents a co-optimization modeling framework that incorporates market participation and market price uncertainties into the capacity allocation decision-making problem through a stochastic programming formulation. Optimal scenario-dependent generation scheduling strategies are obtained. The third part of the thesis is devoted to analyzing the risk premium present in the electricity day-ahead forward price over the real-time spot price. This study establishes a quantitative model for incorporating transmission congestion into the analysis of electricity day-ahead forward risk premium. Evidences from empirical studies confirm the significant statistical relationship between the day-ahead forward risk premium and the shadow price premiums on transmission flowgates.

Um agente soberano sujeito a um choque estocástico deve tomar emprestado para suavizar seu consumo. O mercado financeiro internacional oferece seus fundos, contudo cobra um prêmio por dividir o risco sobre o choque com o governo. O FMI, embora sênior, empresta a uma taxa menor. Encontramos as condições sob as quais a presença do FMI em tal mercado é relevante e positiva ao agente emprestador. Tais condições dependerão do tamanho do prêmio de risco cobrado, que em nossa análise é dado exogenamente. / This paper addresses the role of the International Monetary Fund in the international monetary economy as a senior agent, as observed empirically. A sovereign agent subject to a stochastic shock must borrow to smooth out consumption. The international financial market offers fund, however it charges a premium for sharing the risk over the shock with the government. The IMF, however senior, lends at a lower rate. Hence, the sovereign government must choose its borrower. We find conditions under which the IMF presence in such market is relevant and positive to the borrowing agent. Such conditions will depend on the size of the risk premium charged, which in our analysis will be exogenously given

Usando o modelo de custo de carregamento, compara-se o futuro observado com o justo no período de 04/01/2010 a 18/08/2010. Em um mercado eficiente, esses dois preços não podem divergir, pois eventuais diferenças geram oportunidades de arbitragem. O propósito desta dissertação é investigar duas questões: a primeira, se o modelo de custo de carregamento explica a dinâmica de preços observada; a segunda, se existem possibilidades de arbitragem entre os mercados à vista e futuro. A base de dados é composta de dados intradiários de compra e venda do Ibovespa à vista e futuro, calculados em intervalos de um minuto. Verifica-se que o modelo de custo de carregamento não explica o comportamento do mercado e que maiores discrepâncias de preços ocorrem longe do vencimento. Considerando-se custos de transação e prêmio de risco, existem inúmeras possibilidades de arbitragem no mercado, principalmente na operação que o mercado denomina como 'reversão'. / This study investigates the price efficiency of the spot and futures Ibovespa index. Using the cost of carry model, the “fair” price is compared to the actual price from 04/01/2010 to 18/08/2010. In an efficient market those prices cannot be different because they would lead to arbitrage opportunities. The purpose of this work is to answer two questions: first, if the cost of carry model can explain the market dynamics; second, if there are arbitrage opportunities between spot and future markets. The data set contains intraday bid and ask quotes for the Ibovespa spot and futures calculated every one minute. The findings suggest that the cost of carry model does not explain the market dynamics and that most of the arbitrage opportunities occur far from the maturity of the contract. Considering transaction costs and risk premium, there are many arbitrage opportunities, especially in an operation called “reversion”.

Adicionalmente, a inflação implícita terá uma seção de resultados semelhante ao encontrado para o prêmio de risco de inflação. Foram encontradas na literatura, tanto local quanto na estrangeira, poucas referências que tinham como tema central o prêmio de risco de inflação, a literatura encontrada é mais vasta ao buscarmos por inflação implícita ou taxa natural de juros. Os modelos construídos para mercados estrangeiros visam eliminar o problema da defasagem nos indexados de inflação dos títulos reais, como tanto no trabalho de Evans quanto de Grishchenko e Huang onde, para os mercados britânico e americano, respectivamente, aplicam um modelo que visava reduzir o ruído gerado pela defasagem no indexador de inflação. Para o mercado local, temos uma literatura mais focada em inflação implícita, no qual podemos notar em Vicente e Graminho que realizam a decomposição de todos os componentes da inflação implícita, inclusive o prêmio de risco de inflação. Foi possível tirar algumas conclusões sobre quais variáveis podem afetar o prêmio de risco de inflação e de qual forma, destas, destacou-se o CDS e as expectativas de inflação para períodos condizentes com os analisados para juros reais e nominais. / In this work many regressions towards the inflation risk premium for the Brazilian economy will be estimated, with data from January 2006 to December 2017. In addition to that, there will be a topic where we can find similar results for the implicit inflation as the ones obtained for the inflation risk premium. In the bibliography we found a few references for both local and foreign studies about the main topic, the inflation risk premium, the bibliography is more common to implicit inflation and natural interest rates. The models constructed for the foreign markets focused on minimizing the inflation lag problem on the indexed real bonds, both Evans's work and Grishchenko and Huang tried to minimize this problem with their models, for the British and American economies, respectively, their models tried to build an alternative real termstructure without this inflation lag. For the local market we found a bibliography more focused on implicit inflation, such as in Vicente and Graminho who studied the implicit inflation and all of its components, including the inflation risk premium. It was possible to take a few conclusions about some economic variables and its relation to inflation risk premium, if it exists. From these variables, we highlight the CDS and inflation expectations in consistent periods with those used for real and nominal interest rates.

The aim of this paper is to present the main causes responsible for the behavior of Backwardation and to identify the properties that characterize the equilibrium in agricultural commodit y prices. Be the existence of risk premium or the convenience yield, the unders tanding of the effects on the replication of future price and on the term structure of commodity prices remains an open issue. On the other hand, t he p remise of perfect p ortfolio replication and the absence of market frictions imply that the understanding of c ommodity price Backwardation comes from the understanding of the stochastic process of the underlying asset itself . The risk - neutral pricing allied with signs of reversion in prices supports pricing models such as Schwartz and Smith (2000), whose calibration and results will be presented for soybeans. / A relação entre preços do mercado spot e do mercado futuro e a evidência de Mercado Invertido (backwardation) na estrutura a termo de commodities têm tido ênfase na literatura de economia e de finanças. O objetivo deste trabalho é apresentar as principais causas responsáveis pelo comportamento de Mercado Invertido e identificar as propriedades que caracterizam o equilíbrio de preços em commodities agrícolas. Seja pela existência de prêmio de risco ou do benefício de conveniência, o entendimento dos efeitos sobre a replicação do preço futuro e sobre a estrutura a termo de preços ainda permanece em aberto. A premissa de perfeita replicação de portfólios e a ausência de fricções de mercado implicam, por outro lado, que o entendimento do comportamento de Mercado Invertido advém da compreensão do processo estocástico do próprio ativo subjacente. O apreçamento neutro ao risco, amparado pelos sinais de reversão de preços, permite a modelagem de preços conforme o proposto em Schwartz e Smith (2000), cuja calibração e os resultados serão apresentados para a soja.

Les articles constitutifs de cette thèse analysent les défaillances des marchés financiers traditionnellement identifiées par les économistes (associées aux externalités, aux asymétries d'information et à l'incomplétude des marchés) et les réponses des pouvoirs publics. Une observation centrale est que les interventions publiques ne résultent presque jamais d'une analyse à froid de ces défaillances de marché, mais se décident dans l'urgence pour répondre aux dysfonctionnements les plus évidents observés lors d'une crise. Cette approche pragmatique et a-théorique conduit à des interventions mal calibrées. Ces articles s'attaquent notamment à la politique du prêteur en dernier ressort qui encourage l'endettement à court terme des institutions financières, et nourrit le risque systémique. Ils soulignent également les risques de certaines réformes décidées à la suite de la crise des « subprime ». Les pouvoirs publics devraient se concentrer sur la fourniture des biens publics clairement identifiés par l'analyse économique (contrôle des « agents » et information), et ne pas multiplier les interventions hasardeuses qui créent parfois plus d'imperfections de marché qu'elles ne prétendent en résoudre. / The constituent articles of this dissertation analyze the financial market failures traditionally identified by economists (associated with externalities, information asymmetries and incompleteness of markets) and the policy responses. A central observation is that public interventions have almost never resulted from a cold analysis of these market failures but are decided in a hurry to respond to the most obvious shortcomings observed during a crisis. This pragmatic and a-theoretical approach leads to poorly calibrated interventions. These articles are addressing in particular the lender of last resort policy that encourages the issuance of various short-term debts by financial institutions and feeds systemic risk. They also highlight the risks of certain reforms decided after the "subprime" crisis. Governments should focus on the provision of public goods clearly identified by economic analysis (control of "agents" and information), and should not multiply risky interventions that sometimes create more market imperfections than they claim to solve.

[pt] Na década de 1990, diversos países, inclusive o Brasil, entre 1996 e 2003, iniciaram a reestruturação de seus setores elétricos e criaram mercados livres para negociação de energia. O crescimento desses mercados tem demandado a adaptação de instrumentos financeiros de gestão de riscos e retornos as suas especificidades. No Brasil, o mercado tem, ainda, uma estrutura de balcão desorganizado e descentralizado, o que dificulta seu aprendizado. Os contratos a termo de energia elétrica, negociados bilateralmente, no país, são o principal instrumento para a mitigação de riscos e a avaliação de investimentos. Nesse contexto, o objetivo deste estudo é compreender melhor a dinâmica dos preços a termo de energia elétrica praticados no Brasil. Assim, é proposto um método para construção de curvas a termo com base apenas em informações de mercado e feita uma primeira aplicação dessa metodologia. Alguns indícios ficaram, então, evidentes sobre o comportamento do mercado brasileiro a termo de energia elétrica: configuração de contango em alguns períodos, presença de elevados prêmios de risco e aderência apenas relativa dos preços a termo às expectativas de futuros preços à vista. Estudos realizados a partir de mercados estruturados de energia elétrica suportam essas evidências. / [en] In the 1990s, several countries, including Brazil, between 1996 and 2003, began to restructure their electricity sectors and established free markets for energy trading. The growth of these markets has required the adaptation of financial instruments for risk management and return to their specifications. In Brazil, the market has still a disorganized and decentralized OTC (over the counter market) structure, which hinders their learning. The forward contracts for electricity, negotiated bilaterally, in the country, are the primary instrument to mitigate risks and evaluate investments. In this context, the objective of this study is to better understand the dynamics of the forward price of electricity negotiated in Brazil. Thus, we propose a method to construct the forward curve based only on market information and made a first application of this methodology. Some clues were then evident on the behavior of the Brazilian forward market of electricity: contango set in certain periods, presence of high risk premiums and only partial adherence of forward prices on the expectations of future spot prices. Studies based on structured electricity markets support these evidences.

Cette thèse étudie le rôle joué par les investisseurs financiers sur les marchés des matières premières, connu sous le nom de financiarisation des matières premières. Elle est constituée d’une partie théorique et d’une autre empirique. Les recherches menées visent à étudier la participation des investisseurs, détenant des portefeuilles d’actions, aux marchés à terme de matières premières, pour des raisons de diversification. De plus, cette diversification peut être obtenue en investissant dans un panier de produits de base. Le premier chapitre analyse théoriquement l’interaction entre le marché des matières premières et celui des actions. Le deuxième chapitre étudie empiriquement l’impact du choix des investisseurs financiers sur la prime de risque des contrats à terme sur les matières premières. Il s’intéresse principalement à trois produits de base : pétrole brut (WTI), fioul pour chauffage et gaz naturel. Le troisième chapitre étudie théoriquement l’intégration de deux marchés de matières premières. Nous clarifions certaines considérations concernant l’effet de la financiarisation sur lesquelles la littérature existante reste hésitante. Nous démontrons le pouvoir d’influence qu’exercent les investisseurs sur le marché des matières premières. Toutefois, ceci dépend de la nature de la position de l’investisseur sur le marché à terme. De manière générale, la financiarisation entraîne la hausse des prix spot, des prix des contrats à terme et des niveaux des stocks. Nous montrons aussi que les investisseurs représentent un canal de transmission entre les marchés de matières premières. Leurs effets étendus se limitent à la corrélation croisée des marchés de matières premières. Enfin, nous montrons que les rendements des marchés d’actions sont devenus un déterminant de la prime de risque des contrats à terme après la crise financière de 2008. Cet effet des rendements des actions est indifférent entre les maturités courtes et longues. / This dissertation studies the role of financial investors on commodity markets, which is referred as financialization of commodity. The content of the dissertation splits to theoretical and empirical work. The implemented researches are motivated by the participation of investors, who own stock portfolios, in commodity futures markets for diversification reasons. Furthermore, that diversification is likely achieved by investing in a basket of commodities. The first chapter investigates, theoretically, the interaction between commodity and stock markets. The second chapter studies, empirically, the impact of financial investors on the commodities futures risk premium. It focuses on studying three commodities: crude oil (WTI), heating oil and natural gas. The third chapter examines, theoretically, the integration between two commodity markets. We clarify the hesitating of the previous literature in finding evidences of the impact of financialization. We confirm the influential power of investment in commodity market. However, that depends on the financial investors positions taken in the futures market. Generally, financialization increases the spot prices, the futures prices and inventory levels. We find, also, that investors are a transmission channel between commodity markets. Their effects spread out restricted to the cross commodity markets correlation. Finally, stock market returns became effective determinant of the futures risk premium after 2008 financial crisis. Also, the effect of the stock returns indifferent between short and long maturities.
