Diploma Thesis focuses on Fed Model testing and its credibility on market data. The research is based on Gordon Model and Capital Asset Pricing Model (CAPM), it explains, what the basic features of the Fed Model are and describes its derivation from Gordon Model. The Thesis shows possible Fed Model limitation. It uses the US market, Great Britain and Germany 1979 -- 2011 data to demonstrate validity of the model. Eventually possible reasons of Fed Model development in period 2002 -- 2011 are presented.

隨著金融市場的開放，越來越多的金融商品被開發出來以迎合市場參予者的需求，利率衍生性金融商品是一種以利率為標的的一種新金融商品，而這種新金融商品的交易量也是相當的可觀。我們在設計金融商品的第一步就是要去定價，在現實社會中利率是隨機波動的而不是像在B-S的選擇權公式中是固定的。隨機利率模型的用途就是在描述利率隨機波動的行為，進而對利率衍生性金融商品定價。本文嘗試以隨機利率模型估計台灣公債市場的殖利率曲線，而殖利率曲線的建立對於固定收益證券及其衍生性金融商品的定價是很重要的。在台灣大部分的利率模型的研究都是利用模擬的方式做比較，這也許是因為資料取得上的問題，本文利用CKLS(1992)所提出的方式以GMM(Generalized Method of Moment)的估計方法，利用隨機利率模型估計出台灣公債市場的殖利率曲線。本文中將三種隨機利率模型做比較他們分別為: Vasicek model (Vasicek 1977),、隨機均數的Vasicek 模型 (BDFS 1998) ，以及隨機均數與隨機波動度的Vasicek 模型 (Chen,Lin 1996). 後面兩個模型是首次出現在台灣的研究文獻中。在本文的附錄中將提出如何利用偏微分方程式(PDE)的方法求解出這三個模型的零息債券價格的封閉解(Closed-Form Solution)。文中利用台灣商業本票的價格當作零息債券價格的近似值，再以RMSE (Root mean squared Price Prediction Error)作為利率模型配適公債市場價格能力的指標。本文的主要貢獻在於嘗試以隨機利率模型估計出台灣公債市場的殖利率曲線，以及介紹了兩種首次在台灣研究文獻出現的利率模型，並且詳細推導其債券價格的封閉解，這對於想要建構一個新的隨機利率模型的研究人員而言，這是一個相當好的一個練習。 / With the growth in the area of financial engineering, more and more financial products are designed to meet demands of the market participants. Interest rate derivatives are those instruments whose values depend on interest rate changes. These derivatives form a huge market worth several trillions of dollars. The first step to design or develop a new financial product is pricing. In the real world interest rate is not a constant as in the B-S option instead it changes over time. Stochastic interest rate models are used for capturing the volatile behavior of interest rate and valuing interest rate derivatives. Appropriate models are necessary to value these instruments. Here we want to use stochastic interest rate models to construct the yield curve of Taiwan Government Bond (TGB) market. It is important to construct yield curve for pricing some financial instruments such as interest rate derivatives and fixed income securities. 　In Taiwan Although most of the research surrounding interest rate models is intended towards studying their usefulness in valuing and hedging complex interest rate derivatives by simulation. But just a few papers focus on empirical study. Maybe this is due to the problems for data collection. In this paper we want to use stochastic interest models to construct the yield curve of Taiwan’s Government Bond market. The estimation method that we use in this paper is GMM (Generalized Method of Moment) followed CKLS (1992). I introduce three different interest rate model, Vasicek model (Vasicek 1977), Vasicek with stochastic mean model (BDFS 1998) and Vasicek with stochastic mean and stochastic volatility model (Chen,Lin 1996). The last two models first appear in Taiwan’s research. In the Chapter 3, I will introduce these models in detail and in the appendix of my thesis I will show how to use PDE approach to derive each model’s zero coupon bond price close-form solution. In this paper we regard Taiwan CP (cmmercial Paper) rates as a proxy of short rate to estimate the parameters of each model. Finally we use these models to construct the yield curve of Taiwan Government Bonds market and to tell which model has the best fitting bond prices performance. Our metric of performance for these models is RMSE (Root mean squared Price Prediction Error). The main contribution of this study is to construct the yield curve of TGB market and it is useful to price derivatives and fixed income securities and I introduce two stochastic interest rates models, which first appear in Taiwan’s research. I also show how to solve the PDE for a bond price and it is a useful practice for someone who wants to construct his/her own model.

This diploma thesis deals with financing of central government deficit through the issue of government bonds and with overall context which is inextricably linked with this area. There is defined and discussed a basic terminology in terms of bond, budget system, budget deficit and public debt in the introductory theoretical chapters. We can find a description of development and management of central government debt in the Czech Republic in the next practical chapter of this diploma thesis. The gross borrowing requirements of the Czech Republic are largely covered by issue of government bonds and also by savings government bonds since 2011. The last chapter is devoted to the description of the process of a new euro-denominated issue of government bonds which is again shown on the example of the Czech Republic and its Ministry of Finance.

2014年保險法第146條之4修正，增列保險業依保險法規定投資於國內證券市場上市或上櫃買賣之外幣計價股權或債券憑證之投資金額，可不計入其國外投資限額。本研究探討台灣壽險業投資外幣計價國際債券不納入國外投資限額對於台幣公債市場籌資之影響，並分析壽險業投資國際債券之贖回風險。 主要研究結果發現：(1)開放投資國際債券後，壽險業資金運用增加國外投資，但減持公債及國庫券。依據統計分析，顯示壽險業資金運用於國外投資佔比大幅增加時，除專案運用及公共投資外，其餘項目之佔比皆減少。其中台灣公債及國庫券佔比與國外投資佔比呈高度負相關。(2)壽險業對公債需求程度影響國庫籌資之成本，需求程度越低，國庫長天期籌資成本越高。透過複迴歸模型分析發現，壽險持券比(即壽險業持有公債餘額佔公債未償還餘額比例)越低，30年期公債殖利率越高。 透過本文模型，投資國際債券時，應考量可贖回國際債券相對公債之加碼、閉鎖期、國際債券再度發行之可能性與未來市場利率可能走低之幅度。以投資30年期債券為例，當可贖回國際債券相對公債之加碼減少，閉鎖期縮短，利率走跌幅度增加時，贖回風險將增加。因可贖回國際債券之高利率僅為收益率錯覺，利率走低時之贖回風險將抵銷此高利率。依據2014年至2016年債券市場資訊，本文模型評估投資人提前贖回風險為52.45bps。 / The 2014 amendment of Article 146-4 of Insurance Act extending the overseas investment ceiling to the value for foreign currency denominated listed or over-the-counter certificates of domestic stocks or bonds that are invested in by insurance enterprises in accordance with provisions of Insurance Act. This paper investigates the impact of funding in Taiwan government bond market under the overseas investment ceiling with the exclusion of international bonds investment in Taiwan life insurance industry, and analyzes the call risk of international bonds. The main results show that: (1)After the 2014 amendment of Article 146-4 of Insurance Act, foreign investments are increasing, while government bonds holdings are decreasing in investment portfolio of life insurance industry. Based on statistical analysis, as the ratio of foreign investments surging, only the ratio of authorized projects or public investment is increasing, others are falling. Especially, the ratio of government bonds and that of foreign investment are strongly negative correlation. (2) Demand of government bond of life insurance industry has impact on the funding cost of Taiwan government. The lower the demand, the higher the funding cost. Through multiple regression model, the result shows, the lower the bond holding ratio of life insurance industry, the higher the yield of Taiwan 30-year government bonds. According to the model in this paper, spread between callable international bond and government bond, lock-up period, the probability of re-issuance in international bond market, and the downtrend of interest rate should be all considered when investing in international bonds. The high yield of callable international bond is yield illusion to investors,since is largely offset by call risk. According to the model with bond market data between 2014 to 2016, the assessment of call risk is 52.45bps.

本研究計畫探討以RN神經網路模型預測國內債券價格的效度。目前一般用於財務預測的神經網路論著主要為BPN模型，惟BPN模型有其限制，所以本研究計畫將（1）分析比較統計計量模型，BPN神經網路，RN神經網路系統對國內公債價格之預測績效。（2）分析不同時期的預測能力，找出景氣和預測變數的關係，同時將比較各個時期統計計量模型和神經網路模型是否同時有效， 抑或有些有效， 有些無效，以探討各工具是否具有互補性或替代性。並探討預測績效是否受到背後經濟環境的影響。 我們研究對象為國內公債，其每日交易資料取樣時間自民國八十一年開始。影響債券價格的因素可拆解成實質利率，預期通貨膨脹率和風險貼水三層面，本研究總體變數之選取，亦循此三項範疇以求周延。 本研究之研究成果對理論及實務應用將有下列三項預期貢獻：（1）比較不同其常的債券在不同景氣狀況下，各不同預測模型的預測效度差異，探討各時期各工具之預測能力，可提供投資實務界對預測工具之選擇，應用與搭配。（2）對債券報酬率預測研究，分析總體變數，利率風險等變數對債券報酬率的影響，可進一步暸解影響債券價格的相關因素及程度。（3）以往神經網路應用在財務預測領域上， 皆以BPN 神經網路為主，此處引進RN神經網路，比較兩者的表現，可提供學術理論界之驗證。 / This research project empirically investigates the accuracy of Reasoning Neural Networks (RN) in forecasting Taiwan's bond prices. We explore (1) the relative predictive abilities of Vector Error Correction Model (VECM), which serve as a representative econometric model, Back Propagation Neural Networks (BPN), which is adopted by most current studies in the application of neural networks in finance, and RN, and (2) th3 potential variations in the three models' predictive power in different phases of economic cycle. Specifically, we aim to study if the three models substitute or complementone another. In addition, we explore the extent to which the relativepredictive abilities of the three models varies with underlying macroecomonic factors. The explanatory variables adopted in this study include all potential drives to (real) risk-free rate, expected inflation rate, and riskspremiums. In this study, we examine the government bond terms to maturity,coupon rate, and prices of government bonds during 1992-1995. This project would contribute to both academic and application researchin the following three aspects : (1) Few, if any , prior study explores whether and how various neuralnetworks and/or eco- nomic models perform under different macro-economicvariables. Our empirical results may indicate an appropriate model ( ormodels ) to improve forecasting of bond prices. (2) This study shows how RN, BPN, and VECM models perform in forecastinggovernment bonds yields to maturity. (3) The BPN model prevails in financial forecasting. Nevertheless, BPNis subject to a few short comings and may thus be a sub-optimal model. This study analyzes if RN is more cost-effective in forecasting bond prices than BPN.

近年來，政府會計之改革為各國探討之議題，本研究探討當政府公部門財務報告採用國際會計準則編製，並且經過獨立審計機關查核後，對其發行公債之殖利率利差之影響。本研究從英國債務管理辦公室及倫敦證券交易所之資料庫，蒐集英國中央政府發行公債之資訊，以 2006 年至 2014 間有交易行為之公債為樣本，進行迴歸分析。結果顯示，公債殖利率利差與採用國際會計準則呈現顯著負相關，意即政府報表採用國際財務報導準則，會使市場投資人獲得更透明之財務資訊，而預期公債之無法償還風險降低，且更加願意投資公債。除此之外，當政府提供依國際財務報導準則編製之政府財務報告，再經過會計師查核，審計效果與殖利率利差亦呈現負相關。敏感性測試則指出，當不考慮金融危機的非常規狀況時，同樣可以顯示出相同結果。 / The reform of government accounting systems has become a trend in many countries during recent decades. This study investigates the effect on sovereign bond yield spread of adopting IFRS in government sector, and how yield spreads might be affected after financial reports are audited. Data of tradable UK sovereign bonds are collected from UK Debt Management Office and London Stock Exchange for the period of 2006-2014. Based on the results of regression analysis, the adoption of IFRS by UK governments is negatively associated with gilt bond yield spreads, which means sovereign risk is perceived to be lower by the investors after the adoption of IFRS by central government. When the IFRS-based government financial reports are audited, negative connections between audited reports and yield spreads provide further evidence that investors show higher faith in the sovereign bonds. Additionally, the results remain the same when data of 2009, an abnormal year because of world financial crisis are added back to the regression.

Themes my diploma is ,,Bonds trading on the capital market in the Czech Republic``. In introductory part of my thesis I deal with theoretic summary and functioning of capital market, regulation and supervision of capital market and individual subjects acting in this market. In more detail I deal with describeing the Prague Stock Exchange and company RM-System. I further define conception the bond and I describe long bonds, theirs basic kinds and conceptions used in the bonds. I also allude to series of different kinds of the bonds, that the offer on the international markets. Next part of my thesis is aimed to describe the development of the Czech market of bonds. I analyze the development of bonds trading in the last of several years on the regulated markets and the OTC-markets in the Czech Republic. In the close of my thesis I analyze the development of bonds trading on the Czech market of bonds in comparasion with Slovakian, Polish and Hungarian markets. This analysis was take in on comparision of the Stock Exchange of chosen countries.

The main aim of this diploma thesis is to analyze benefits of the establishment of the European Rating Agency. The partial aim is to determine the influence of the credit ratings on economics situation in selected European countries and to analyze problems of current credit rating industry. A slight impact of the credit ratings on the observed countries has been found by way of the analysis of evolution of the yields of ten-year government bonds and the prices of CDS contracts on these bonds. Non-perfect competition, weak transparency of the rating process and conflict of interest are considered as the most important problems of the credit rating agencies. By way of the analysis of the ability of the European Rating Agency to remove or at least to partially eliminate discussed problems has been found that the European Rating Agency would not be able to remove all problems of the credit rating industry. The uncertainty about the independence of the European Rating Agency is the biggest weakness of this agency. For this reason, we can't expect that the European Rating Agency would be able to make the credit rating process more efficient and improve the situation in the credit rating industry.

Il est des notions servant d’architecture aux opérations d’épargne tellement anciennes, voire un tantinet désuètes et « exotiques », qu’elles finissent par n’intéresser qu’une poignée de spécialistes. C’est le cas de la tontine qui occupe une place résolument atypique et différenciée. Son traitement est tout aussi significatif que paradoxal. À son évocation, contrairement aux autres techniques juridiques et malgré sa relative confidentialité, n’importe quel particulier est capable de tracer une trame, peu ou prou précise, mais néanmoins avec une constance dès lors qu’il s’agit de ses deux points cardinaux que sont la survie, comme condition exécutoire, et la mort, comme condition résolutoire. Mais là s’arrête la bonne intuition et commencent un ensemble de malentendus ainsi qu’une certaine amphibologie. De prime abord, l’histoire de la tontine ne peut être écrite au singulier. Elle a changé d’objet à trois reprises, de 1653 à nos jours. Quand bien même son régime est parvenu à se stabiliser, la tontine est redevenue multiforme, faisant intervenir alternativement la vie et le décès comme fondement de l’extinction des obligations. Ensuite, sa représentation est toujours occultée par des récits des abus alors que la loi du 17 mars 1905 est parvenue à les sécuriser définitivement. Enfin, les démarches d’introspection ont été continuellement ramenées à la comparaison avec l’assurance vie. Peu convaincantes, elles butent toutes sur le postulat intangible qui sépare la tontine de l’assurance. De là, il faut définitivement se convaincre que la tontine est une opération d’épargne sui generis, définie par huit éléments constitutifs, dotée d’un droit spécial et couverte par le Code des assurances (articles R.322-139 à R.322-159). / There are architectural notions related to savings’ plans so ancient, even indeed slightly outmoded and « exotic », that they end up interesting only a handful of specialists. This is the case of tontine which fills a resolutely atypical and differentiated niche. Its processing is as significant as it is paradoxical. In fact, unlike other legal techniques and despite its relative confidentiality, any individual is capable of drawing a more or less accurate yet constant framework, that it includes two cardinal points which are survival as an execution clause, and death as a cancellation clause. But good intuition stops there and a whole series of misunderstandings begin, as does a certain amphibology. At first sight, tontine history cannot be written in a singular mode. Tontine has changed its object three times, from 1653 to this day. Although its system had become reliable, tontine merged again into a many-faceted profile, applying alternately, life and death events as a foundation of obligation extinction. Furthermore, tontine representation is always overshadowed by a sulphurous reputation even though the March 17th 1905 bill managed to definitely secure these operations. Finally, introspection initiatives have been continuously reduced to a comparison with life insurance. Unconvincing, they always trip over the intangible premise which separates tontine from insurance. From there, it is unequivocal that tontine is a sui generis savings’ plan, defined by eight constitutive elements, endowed with a specific legal system and covered by the insurance code (articles R.322-139 to R.322-159).

Cette thèse s'intéresse aux questions d'accès aux marchés financiers dans les économies émergentes et en développement. La première partie donne un aperçu général des conséquences macroéconomiques de l'un des régimes de politique monétaire le plus favorable au marché - le ciblage d'inflation - en utilisant le cadre d'analyse de la méta-analyse. La deuxième partie analyse le risque et la stabilité des marchés obligataires des États. La troisième et dernière partie examine les effets disciplinaires résultant de la participation aux marchés obligataires souverains. Plusieurs résultats émergent. Au chapitre 1, les résultats indiquent que la littérature sur les effets macroéconomiques du ciblage d'inflation est sujette à des biais de publication. Après avoir purgé ces biais, le véritable effet du ciblage d'inflation reste statistiquement et économiquement significatif à la fois sur le niveau de l'inflation et la volatilité de la croissance économique, mais ne l’est pas sur la volatilité de l'inflation ou le taux de croissance économique réel. Aussi, les caractéristiques des études déterminent l’hétérogénéité des résultats de l'impact du ciblage d’inflation dans les études primaires. Le chapitre 2 montre que l'adoption d'un régime de ciblage d'inflation réduit le risque souverain dans les pays émergents. Cependant, cet effet varie systématiquement en fonction du cycle économique, de la politique budgétaire suivie, du niveau de développement et de la durée dans le ciblage. Le chapitre 3 montre que les envois de fonds des migrants, contrairement aux flux d'aide au développement, permettent de réduire le risque souverain. Cette réduction est plus marquée dans un pays avec un système financier moins développé, un degré d'ouverture commerciale élevé, un espace budgétaire faible et sans effet dans les pays dépendants des envois de fonds. Le chapitre 4 montre que les pays ayant des contrats d’échange sur risque de crédit sur leurs dettes sont plus sujets à des crises de dette. Il constate également que cet effet reste sensible aux caractéristiques structurelles des pays. Le chapitre 5 montre que la participation aux marchés obligataires de long terme (domestiques et internationaux) encourage les gouvernements des pays en développement à accroître leurs recettes fiscales intérieures. Il révèle également que l'effet favorable dépend du niveau des recettes de seigneuriage, d’endettement, du régime de change, du niveau de développement économique, du degré d’ouverture financière, et du développement financier. Le chapitre 6 montre que la présence de marchés obligataires domestiques, de long terme et liquides réduit considérablement le degré de dollarisation financière dans les pays en développement. Cet effet est plus important dans les pays avec un régime monétaire de ciblage d’inflation ou de change flottant, et à règles budgétaires. Enfin, il constate que la présence de marchés obligataires domestiques réduit la dollarisation financière à travers la baisse du niveau et de la variabilité de l'inflation, de la variabilité du taux de change nominal, et des revenus de seigneuriage. / This thesis focuses on some critical issues of the access to international financial markets in developing and emerging market economies. The first part provides a general overview of the macroeconomic consequences of one of the most market-friendly monetary policy regime—inflation targeting—using a meta-regression analysis framework. The second part analyses government bond market risk and stability. The last part investigates the disciplining effects of government bond market participation—bond vigilantes. In Chapter 1, the results indicate that the literature of the macroeconomic effects of inflation targeting adoption is subject to publication bias. After purging the publication bias, the true effect of inflation targeting appears to be statistically and economically meaningful both on the level of inflation and the volatility of economic growth, but not statistically significant on inflation volatility or real GDP growth. Third, differences in the impact of inflation targeting found in primary studies can be explained by differences in studies characteristics including the sample characteristics, the empirical identification strategies, the choice of the control variables, inflation targeting implementation parameters, as well as the study period and some parameters related to the publication process. Chapter 2 shows that the adoption of inflation targeting regime reduces sovereign debt risk in emerging countries. However, this relative advantage of inflation targeting—compared to money or exchange rate targeting—varies systematically depending on the business cycle, the fiscal policy stance, the level of development, and the duration of countries’ experience with inflation targeting. Chapter 3 shows that remittances inflows significantly reduce bond spreads, whereas development aid does not. It also highlights that the effect of remittances on spreads arises in a regimes of lower developed financial system, higher degree of trade openness, lower fiscal space, and exclusively in non-remittances dependent regimes. Chapter 4 indicates that countries with credit default swaps contracts on their debts have a higher probability of experiencing a debt crisis, compared to countries without credit default swaps contracts. It also finds that the impact of credit default swaps initiation is sensitive to several structural characteristics including the level of economic development, the country creditworthiness at the timing of credit default swaps introduction, the public sector transparency, the central bank independence; and to the duration of countries’ experiences with credit default swaps transactions. Chapter 5 shows that bond markets participation encourages government in developing countries to increase their domestic tax revenue mobilization. Finally, it finds that bond markets participation improves the mobilization of internal taxes, compared to tax on international trade, and reduces their instability. Chapter 6 shows that the presence of domestic bond markets significantly reduces financial dollarization in domestic bond markets countries. This effect is larger for inflation targeting countries compared to non-inflation targeting countries, is apparent exclusively in a non-pegged exchange rate regime, and is larger when there is a fiscal rule that constrains the conduct of fiscal policy. Finally, it finds that the induced drop in inflation rate and its variability, nominal exchange rate variability, and seigniorage revenue are potential transmission mechanisms through which the presence of domestic bond markets reduces financial dollarization in domestic bond markets countries.
