Full textThe main function of derivatives markets is to transfer uncertainty- bearing from investors who want to get rid of it to those who are more eager to carry that burden. Their specific feature is to make the separation of risk management from the underlying assets possible. A higher degree of specialization of tasks results from this. However, a realistic theory requires that one takes into account uncertainty as something which is not reducible to probabilistic risks. It must then end up demonstrating that specialization extends the division of labor only indirectly. This outcome is essentially obtained through an increase in savings –as a counterpart to increased specialization- and the corresponding fall of interest rates. If the derivatives markets’ existence then seems to be a factor of increased prosperity, their effects on the price discovery process are more ambiguous however, and we identify several weaknesses in the literature which suggest the necessity of further theoretical advances in order to be able to provide a definitive assessment. We also explain how some derivatives foster increased indebtedness and in particular how they can feed the current sovereign debt crisis. In order to do so, we focus on credit default swap contracts. Finally, we argue that these credit default swaps magnify the moral hazard which results from the very existence of fiat money, by making some especially risky endeavors affordable through a transfer of uncertainty-bearing to unwilling third parties. Hence an explanation of the growth of volumes on these markets and an account of their meaning is provided

Full textThe influence of derivative markets on the volatility of the underlying claims can be viewed with a theory or empirical approach. A first theoretical approach is based on the efficiency theory. It concludes to a stabilizing influence of the future markets if the two other theoretical functions of the future markets are realized, i. E. The diffusion of information with the publication of the future prices and the transfer of the risk to the agents who accept to support it. A second theoretical approach concludes to a destabilizing influence when the efficiency is rejected. This rejection can take two forms: first, the hypothesis of the efficiency model can be rejected, because of asymmetric or imperfect information. Secondly, the efficiency can be rejected ex post, because of the adoption of destabilizing behavior like mimetism or short horizon by the participants on the markets. The empirical approach is based on a model which multiplies the indexes of the stabilizing or destabilizing influence. So the study of interactions between the prices of the two markets, in an error correction model, allows us to analyses the informational effect of the derivative market and its correction effect on the spot market. These two elements, if they are significative, indicate a stabilizing influence. In an other hand, the study of the interactions of the volatility of the two markets indicates the presence of a propagation of instability of the future markets on the spot market. The application of this model to the CAC 40 contract has showed its stabilizing influence in general and even in a period of financial crisis. On the contrary, the notional future contract is showed to have a destabilizing influence on the underlying market, both in general and in a period of financial crisis

Full textNotional bond futures volatility, which measures the sensibility of the contract to movements in financial market, is estimated from different types of options on long bond futures evaluation models. Whaley model (with classical hypothesis of Black and Scholes model, American option) gives the best result within the different models which were tested. The quality option gives the futures seller the choice of delivery bond at the expiry date. Obtained by arbitrage, it always seems to be under evaluated by the market. It can be explained by the fact that the market limits the official bond list with two or three deliverable bonds, and when a bond goes out of the official list, the next delivery month, it's almost the cheapest to deliver

This, by transcribing certain concepts of derivatives markets at the level of the market of the reinsurance. This research articulates around three main questions : What is the analogy between the financial market and the market of the reinsurance? In other words, how a "financial" option can converge on an insurance premium?. What are the advantages of derivatives markets of the reinsurance?. How can we explain the success or the failure of these derivatives markets of the reinsurance?

Full textThis work deals with the process of price formation in the french stock index market and stock index futures market. Most of the analysis is concerned with the role arbitrageurs play in this join dynamics. The investigation is based on intraday time stamped data (price, quotes, orders and depth at the best quotes) recorded in 1994 and 1995 by the sbf, the french stock exchange, and the matif, the french futures markets. We first show that the market frictions make the arbitrage decision a strategic one, what is in accord with empirical findings. The action of arbitrageurs depends on liquidity pressure and/or information arrival. The hypothesis of an informational advantage of the futures market is also analyzed. We show that half of the conditional variance of the stock index returns, as represented by a garch process, is indeed explained by arbitrage trading, but only twenty percent of the variance of the futures. We next analyze the competitive structure of arbitrage trading in paris. We cannot reject the hypothesis of a competitive/oligopolistic structure of arbitrage. Mispricings are then quite we find evidence for both an information effect and a liquidity effect of arbitrage trading, even if the behavior of the basis is taken into account. Nevertheless, the liquidity effect does not affect the price formation process in the long run. The incentive mechanism of liquidity provision explains this empirical finding

Arbitrage opportunities and possibility of making porfits on the basis dependencies in the past prices are examined in terms of "nationnel" contract traded on the matif. On the basis of the results this market appears to be inefficient. In addition the forcasting ability of: the futures prices in the notionnel contract and the long interest rates in the cash market, is examined, the matif is efficient in this sens. The matif has increased the prices of the underling bonds at the bigining of the trading in this market. The analusis of the influence of the matif on the cash market shows us that the matif has stabilized the cash market in the short term and sestabilized it in the long term. Finaly, the matif has functioned well during the crash of october 1987

Full textFor twenty years, futures markets of commodities and financial products have known a considerable development. This development has been intended to be an answer to the raise of price risks, interest rates and foreign exchange rates since 1973 thanks to its several economic functions, such as hedging, arbitrage, speculation, information and stabilization. Futures markets are an efficient tool of management of commodities price risks, interest risks of financial products and currency foreign exchange risks specific to all those risks. The economic costs resulting from the use of futures markets are often weaker than those depending on other organisations, national programmes, stabilization and national agreements ; however, the yields made are linked mainly to the opportunities grasped by the user of those markets. On february 15th, 1986, the futures markets of financial instruments (matif) was created in paris. The mecanisms of this type of market have already been working in many markets in the world. Indeed, the system of trading and the characteristics of the most negociated contract on the matif are inspired. To agreat extent, by those of chicago board of trade. Under the law 87-1158 of december 31st, 1987, the matif is the result of the fusion of the financial instruments futures markets and the commodities futures market existing in commodity exchange in paris

Full textThe application of derivative instruments to corporate finance is a vast and important field of research. The aim of this work is to study exotic options, i. E. Derivatives characterized by greater flexibility and greater precision than their traditional counterparts. First, we examine so-called fundamental exotic options. We present the most well-known products for each fundamental exotic option class, such as barrier options, compound options, options on average, pay-back options, extendible options and options on the minimum or the maximum of two risky assets, by successively analyzing their mechanisms, their valuation, their hedging, and their applications to companies' financial management. New, more complex types of exotic options are possible based on fundamental exotic options. In this perspective we propose extendible options with underlying asset changes, which have the particularity of simultaneously combining two exotic characteristics, that of extendible options and that of multi-asset options. Valuation and hedging of these options arc studied here in detail. Among numerous possible uses, this type of exotic options could interest firms in terms of their warrant issues so as to reduce the non-exercise risk of these securities and keep existing investors in the same group. Through a concret study of executive remuneration incitative schemes, we show in the final part of this thesis that by following a methodical procedure, firms can shape their exotic tools to best fit specific problems and specific goals

Full textThis dissertation provides some tools intend to improve valuation of risk and measurement of investment performance. The first two chapters discuss international markets and derivatives. The purpose of the chapter 3 is to develop some consequences of the assumption of no arbitrage opportunities on international markets. Especially, we derive a relationship between risk premium in two countries and the sole volatility of exchange rates. Then, we price cross currency option. Such an option provides an implied correlation coefficient between two currencies. In an empirical study we compare this coefficient with the historical coefficient. The chapter 4 deal with measure of performance using the statistical technique of bootstrap. This technique is attractive in order to resolve problems due to small sample that occur when we measure the performance of a portfolio during a krach, but also because, on every period, we observe only one path of returns and prices. This study includes an empirical part about the performance of a portfolio involving currencies and indices. In the last part, we evaluate the risk of default on future and forward contract and the impact of a margin call mechanism on the risk. For the two kind of contract some numerical simulations are run. The "option of default" is also priced when the future price is ruled by some circuit-breaker regulation

Our meta-case tool allows us to generate design tools based on a training system design method. To reach this goal, we developed a dual problematic : firstly we designed a method meta-model, specific to the educational domain that is based on three components (meta-concepts, meta-rules and metaformalisms) and secondly, we developed a complete set of rules concerning the method meta-model. These rules have three objectives : to ensure the designer's modelling integrity, to define the meta-case design process and to help the expert to use the meta-case tool

Full textIn the supply chain of investment services, trading activity is at the heart of several breakthroughs with the rise of new forms of competition and new regulations. The Market in Financial Instruments Directive (MiFID) constitutes a major revolution in the organization of the trading process in Europe, by abandoning the historical principle of order flow centralization. Innovation and strategic confrontation between market and bulge bracket firms determine the way that markets fragment. We analyze the conditions under which competition mechanisms between those actors can either converge or differ from the objectives of integrity and quality of financial markets. In light of existing complementarities between microstructure and industrial organization of financial markets, we elaborate an original analysis of the consequences of the new regulations. While competition between trading venues can generate positive externalities such as transaction cost decreases or incentives to innovate, it can also damage the price discovery process and market liquidity. However, two arguments can be advanced to support the idea of a virtuous circle. The first, highlighted with the help of a theoretical model of competition, is the lead position of the incumbent (the established market firm) and its interest in organizing competition in order to stimulate market liquidity as whole. The second, studied in an empirical analysis of Euronext Paris, is the difficulty for new entrants to divert order flows managed by regulated markets. Thus, market fragmentation would allow some previous unexpressed liquidity to find a place among new matching services and then, lead to additional transaction volumes

Full textThe writings of Mr. Haroun BOUCHETA, gathered for the title of Doctor of Laws, deal with financial law. Since 2005, drawing on his professional experience, the author regularly publishes articles for both practitioners and academics. The collected writings are of two kinds.First, the author is interested in the legal framework of certain players in the financial markets as well as those of financial instruments and financial techniques.Among the actors studied, central counterparties play an important role. The author's studies on this subject make it possible to understand the specific legal and regulatory environment and to understand its recent developments at European and French levels.As for financial instruments and financial techniques that have been the subject of publications, the author concentrated mainly on derivatives and commodities.Secondly, other writings are more cross-cutting and even forward-looking, as they relate to unavoidable European reforms in financial regulation. In addition to the EMIR regulation, the author devoted several in-depth studies on the reform of the Markets in Financial Instruments Directive (MiFID).These writings of financial law are accompanied by a general introduction. The first part is based on fifteen published articles from the author and is intended to highlight some of the shortcomings of post-crisis financial regulation. In the second part, the author examines the current physiognomy of the sources of financial law and the process of drafting the texts

Full textThe thesis objective is to price credit derivatives such as synthetic CDOs by using advanced quantitative methodologies. We describe the standard market model used for the pricing of synthetic CDO tranches. We then proceed to illustrate the limitations of the standard approach and introduce a new methodology using Normal Inverse Gaussian (NIG) distributions and historical correlations. We compare both approaches in terms of pricing and hedging capabilities and can deduce that our approach is more accurate on both a theoretical and empirical basis. We then extend our research to CDO^2 and introduce two new methodologies for pricing this type of structures. We aiso study the opportunities offered by hedging standardized tranches. We can then conclude that significant model and correlation risks exist in the credit derivatives market. These risks should be taken into account with the credit risk in these types of structured deals

Full textCommodity prices rise observed during the 2000s being concomitant with the increasing presence of financial agents has sparked the researchers’ interest. This price increase occurred while commodity markets have been transformed by new financial instruments or larger investments in these markets. The first chapter of this thesis are studying the impact on commodities of Exchange-Traded Products (ETPs) whose purpose is to provide investors a passive exposure to commodities. During this study, it is shown that the mechanism (called creation / redemption) used to deliver the performance of the underlying commodity to the investors has an impact on the price of the underlying asset, its volatility and its correlation with the stock market. The second chapter demonstrates that ETPs have become major contributors to the price discovery process whereas traditionally this function was performed by the futures market. The final chapter of this PhD thesis is studying seasonality in both the prices and positions of different types of agents on the futures market for agricultural commodities. The results show that seasonal positions in the futures market have been changed by the increased presence of financial agents. This thesis quantifies and demonstrates that new investment vehicles and an increasing number of positions of financial investors in the futures market have changed the financial and fundamental characteristics of commodity markets

Full textThis Ph.D. project aims to study the heterogeneity of information and beliefs among speculators on commodity markets to tackle the issues of the risk premium and volatility puzzles. The first step was to introduce information asymmetry in a storage model. The output is an efficient market where it is possible to distinguish a random informational effect from a deterministic physical effect. The second step is to estimate empirically the parameters of a modified version of the theoretical model above. The rationality hypothesis is relaxed."Chartists," who are trend-followers, are introduced. The goal of this paper is to estimate their influence on asset pricing. The chosen market for the empirical study is the Henry Hub natural gas market. The third step is a model where rational agents and bounded-rational agents interact together in a commodity market. This last chapter shows how trend-followers in the futures market can destabilize the spot market

Full textThis thesis aims to provide innovative theoretical and empirical methods for valuing securities to economics researchers, market makers, and participants, including brokers, dealers, asset managers, and regulators. We propose an extension of the Fundamental Theorem of Asset Pricing (FTAP) tailored to markets with financial frictions. Hence, our asset pricing methodologies allow for more tractable bid and ask prices, as observed in the financial market. This thesis provides both theoretical models and an empirical application of the pricing rule with bid-ask spreads.In our first chapter, we introduce two straightforward closed-form pricing expressions for securities in two-date markets, encompassing a variety of frictions (transaction cost, taxes, commission fees). This result relies on a novel absence of arbitrage condition tailored to the market with frictions considering potential buy and sell strategies. Furthermore, these asset pricing models both rely on non-additive probability measures. The first is a Choquet pricing rule, for which we offer a particular case adapted for calibration, and the second is a Multiple Priors pricing rule.In the second chapter, as a step toward generalizing our asset pricing models, we provide the necessary and sufficient conditions for multi-period pricing rules characterized by bid-ask spreads. We extend the multi-period version of the Fundamental Theorem of Asset Pricing by assuming the existence of market frictions. We show that it is possible to model a dynamic multi-period pricing problem with a one-stage pricing problem when the filtration is frictionless, which is equivalent to assuming the martingale property, which is equivalent to assuming price consistency.Finally, in the third chapter, we give the axiomatization of a particular class of Choquet pricing rule, namely Rank-Dependent pricing rules assuming the absence of arbitrage and put-call parity. Rank-dependent pricing rules have the appealing feature of being easily calibrated because the non-additive probability measure takes the form of a distorted objective probability. Therefore, we offer an empirical study of these Rank-Dependent pricing rules through a parametric calibration on market data to explore the impact of market frictions on prices. We also study the empirical validity of the put-call parity. Furthermore, we investigate the impact of time to expiration (time value) and moneyness (intrinsic value) on the shape of the distortion function. The resulting rank-dependent pricing rules always exhibit a greater accuracy than the benchmark (FTAP). Finally, we relate the market frictions to the market's risk aversion

Full textCommodity futures markets have a long history. However, since the beginning of the 21st century, both the financialization process and the development of futures markets on a non-storable commodity (the electricity) have shake up their functioning.The three essays of this thesis study theoretically and empirically commodity futures markets in different situations of functioning.The first essay is an empirical study that shows that the Samuelson effect exists on electricity derivative markets. As a consequence, it shows that storage is not a necessary condition for such an effect.The second essay is a model that shows how the dynamic behavior of storable commodity prices on a segmented futures market is affected by its physical characteristics, and more precisely by the cost of storage.Further, the third essay is a model that shows that financialization changes the risk sharing function of commodity futures markets, whatever the concerned maturity

Full textThe Market Operator is the for-profit company in charge of organizing and exploiting a regulated market. It has at its disposal several prerogatives it can use to issue binding rules and decisions toward both contractors and third parties. The model of the Market Operator poses certain questions, however. Sound and efficient regulation by the French Financial Market Authority can resolve the issue of conflicts of interest, though the question of the legal qualification of the prerogative remains. To resolve the ambiguity of the model, it is mandatory to take a full understanding of the notion of Market Interest. This collective interest, structuring the legal model of Market Operator, can have two different meanings. It would be legally qualified as a Common Interest in a model of true private law. This model would be built on prerogatives born from private power. These prerogatives grant rights to the Market Operator to accept as binding private rules and decisions for the contracting parties, but not toward third parties. Conversely, it is possible to integrate the Market Interest into the General Interest and create a public model of Market Operator. The official powers held by the Market Operator would permit the issuance of administrative rules binding for everyone
Deng, Shuoqing. "Robust finance : a model randomization approach." Thesis, Paris Sciences et Lettres (ComUE), 2019. http://www.theses.fr/2019PSLED005.
Full textThis PhD dissertation presents three research topics. The first two topics are related to the domain of robust finance and the last is related to a numerical method applied in risk management of insurance companies. In the first part, we focus on the problem of super-replication duality for American options in discrete time financial models. We con- sider the robust framework with a family of non-dominated probability measures and the trading strategies are dynamic on the stocks and static on the options. We use two differ- ent ways to obtain the pricing-hedging duality. The first insight is that we can reformulate American options as European options on an enlarged space. The second insight is that by considering a fictitious extensions of the market on which all the assets are traded dynamically. We then show that the general results apply in two important examples of the robust framework. In the second part, we consider the problem of super-replication and utility maximization with proportional transaction cost in discrete time financial market with model uncertainty. Our key technique is to convert the original problem to a frictionless problem on an enlarged space by using a randomization technique to get her with the minimax theorem. For the super-replication problem, we obtain the duality results well-known in the classical dominated context. For the utility maximization problem, we are able to prove the existence of the optimal strategy and the convex duality theorem in our context with transaction costs. In the third part, we present a numerical method based on a sparse grid approximation to compute the loss distribution of the balance sheet of an insurance company. We compare the new numerical method with the traditional nested simulation approach and review the convergence of both methods to estimate the risk indicators under consideration

Full textCurrently, econometric modelling's contribution, both to economic forecasting and economic policy valuation, is signifiant. However, models term (about five years) is sometimes inadequate. It it possible to extend it? Specifications properties in a long term perspective, and their compatibility, were theoretically studied. Those works pointed out the relationship between long term properties of macroeconomic models and results of theory of growth. So far, questions raised by long-run modelling practise can be expressed using theory of growth's framework: existence and properties of a steady state growth path, and its stability. First, models must provide an analytical framework that allows organisation of inputs contribution to growth. From this point of view, production function is the significant concept. It is widely studied, both using a putty-putty assumption, and a vintage approach. Simulation experiments are used to fith the practical consequence of our results. Yet, it will not do simply to superimpose a model of the business cycle on an equilibrium growth path. In the short run, disequilibriums are explicitly registered in models. Theoritical models of economic growth with disequilibrium can provide interesting exploratory sketchs, that could allow to improve long term properties of econometric models. Concerning disequilibrium on the financial market. .

Full textIn current market conditions, companies in emerging markets have the choice between a short-term debt in local currency and a long-term hard currency financing from international sources to finance their long-term investments. This practice would create either an interest rate gap or a currency gap. As an extent of previous researches and studies covering the question of currency risks diversification in mature financial markets, this thesis is quite distinctive from the existing literature as it focuses on emerging market currencies for which there are little or no hedging options of currency and interest rate risks. The proposed model is based on a fundamentally different approach from existing risk models, seeking to mitigate risks internally through portfolio diversification, rather than by matching supply and demand. This, by analyzing both correlations between emerging market currencies in a portfolio composed of African, Asian, South American and Eastern Europe currencies and the effect of diversification on market risk reduction. The main objective of this thesis is to contribute to the specification and the identification of a risk diversification model while demonstrating that the establishment of a diversified portfolio of emerging market currencies not covered by the commercial banks is a lucrative business over the long-term. With an efficient information system, the proposed model attempts to demonstrate the effect that such hedging products would have on reducing the credit risk of borrowers and hence the lenders. To achieve this aim, the different risks associated with these activities have been identified while choosing the methods for their effective management as well as the modeling of hypothetical exposures created by this activity. The impact of reducing market risk exposure through the usage of interest rate and currency hedging products on the credit risk rating of companies in emerging countries has also been modeled. The current research claims that the choice of currencies does not significantly impact the results as long as the proposed regional limits are respected. The simulation’ results show that managing a diversified currency portfolio under an optimal risk management guidelines can be a lucrative business for banks as the risk mitigation can be effectively done through portfolio diversification

Full textThe thesis is a collection of six papers, all dealing with the yield curve and interest rate risk management. The first paper provides a framework to manage a portfolio of interest rate sensitive instruments. After exhibiting appropriate risk factors, the sensitivity matrix of a portfolio is defined and remarkable strategies illuminated. The second and third paper study the french futures contract on "notionnelle", both in terms of comparing volatility of cash and futures prices during trading and non-trading hours and also of examining the efficiency of this contract in hedging and defining optimal asset allocation. The fourth paper presents the latest tools in asset liability management while the fifth focuses on the use of arbitrage arguments to define the value and interest rate risk of floating-rate instruments, as well as the markup risk. The last paper introduces a "forward-neutral"probability to get a simple expression of the value of a call or of the forward price of any financial asset

Full textThe objective underlying the three chapters of this thesis is the understanding of the functioning of the labor market to make a diagnosis about the potential regulatory role of a public authority in this market. ln the first chapter, I analyze, from a purely "positive" point of view, the ability of the model with search and matching frictions to reproduce short-term fluctuations of labor market variables in the United States. I propose a new calibration strategy, within a general equilibrium framework with sticky prices. In the second chapter (co-written with F. Langot), we study the determinants of changes in the labor supply over the last fifty years. Changes in the tax wedge, and two variables reflecting the institutional framework (the generosity of income in case of "non-employment" and workers' bargaining power), can explain the different trajectories of the rate employment and hours worked observed in the United States and three European economies (France, Germany and the United Kingdom). ln the third chapter, I analyze the performance of two alternative systems of social security, within the framework of a model with heterogeneous agents in terms of wealth. The agents are subject to a risk of unemployment, and the planner can provide insurance through a redistibutive tax system, based on a progressive tax and / or unemployment insurance. The progressive tax system is superior in terms of aggregate welfare to the insurance provided through unemployment benefits, through its effect on the functioning of the labor market

Full textThe contractual freedom of the banker is a freedom among the others. However, it is the most sensitive in so faras it can affect on his activity. Apparently unlimited today, this freedom would have even undeniableconsequences on the safety of the financial system by facilitating the phenomenon of “speculative bubbles”. Thecontract, situated in the heart of the banking and financial activity, would be thus the cause of this reality. Therecent shocks, such as financial crises, require the detailed examination of the national but also internationalbank transactions, especially the most dangerous. Still ignored, the measurement of the contractual freedom ofthe banker proves to be necessary to propose a review. The aim is not thus to rule any banker’s freedom out butto define the degree of contractual freedom to grant to him for each transaction. The idea being to grant him asatisfactory level of freedom while ensuring the safety of financial system. The stake rests finally on theconciliation of the contractual requirement, resulting from the contractual freedom of the banker, with the safetyrequirement of the financial system, necessary for the sustainability of banks and worldwide economy
