Full textThe goal of this dissertation is to study a valuation method of contingent claims in incomplete markets given that the investor tries to maximize his expected wealth with his attitude towards risk. We make the assumption that there exists at least one untraded source of risk in the financial market and that contingent claims written on this source of risk are illiquid. We also make the assumption that it is possible to hedge the investor’s position with a liquid proxy. The first contribution of this work is to show that the price of the contingent claim, namely the indifference price, lies between financial and actuarial pricing. We show the this price can be expressed as the certainty equivalent with a modified risk aversion parameter and under a given probability measure which is not the historical one. The second contribution is directly linked to the first one as it is an empirical illustration of the theoretical result for different types of contingent claims: weather derivatives and options on funds. As for weather derivatives, we consider different valuation approaches and compare them to the indifference price. As for options on funds, we give the price of both a standard option and a barrier option. Lastly, the third contribution provides comprehensive coverage of macro-economic derivatives as inflation-linked options and options written on the French Livret A

Full textThis thesis gathers a set of studies dealing with the problematic of numerical procedures and with the problematic of market data modelling met during the development of an equity derivatives valuation tool. The first part relates to the use of Monte Carlo and Quasi-Monte Carlo simulations in order to price derivatives. It insists more particularly on the choice and the implementation of uniform generators, on the techniques employed to simulate Gaussian variables and on the variance reduction procedures that can be applied to improve the convergence rate of the estimators. The second part relates to the modelling of the market parameters, which influence the stock price dynamic. The first two chapters deal successively with the zero curve construction and the implied volatility surface fitting under the no-arbitrage assumption. The third chapter resolves the European option-pricing problem in the presence of discrete cash dividends

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

Full textThis thesis studies the mechanisms at work when agents exchange derivatives in networks. The general conclusion of this work is the following: when one models simple mechanisms between agents who have different risk tolerances, one obtains behaviors which are similar to those observed in reality, and which are sometimes the source of major trouble. To reach this conclusion, this work uses mathematical modeling based on financial risk measures, made more complex over the chapters and extended using computer simulation. At first, the model shows that agents tend to establish chains of dependence when they have the freedom to trade derivatives. Their behavior leads to the emergence of a point of systemic failure. When modeling incorporates counterparty risk, chains of dependence can worsen general bankruptcy. A computer method is then developed to extend the analysis to the most general case possible; it enables to design optimal derivative products within a very broad framework. Applied to the problem of network derivatives, this method leads to the emergence of more realistic derivatives than previously, such as options. Systemic risk persists, however, raising the threat of general bankruptcy if one of the financial positions is misjudged. Finally, this thesis work proposes a reflection on the scientific value of computer simulations in social sciences. Adopting a point of view stemming from the philosophy of Karl Popper, this thesis proposes to consider simulations as logical counterexamples to firmly established theoretical presuppositions

Full textTwo main classes of theories explain why risk management activities are undertaken by firms. The first one relies on the risk aversion of corporate insiders and states that managerial agency costs may influence the corporate hedging decision. The second one is based on shareholders value maximization and states that hedging can enhance the firm value by reducing various costs implied by highly volatile cash flows. In this study, we examine derivatives holdings by French firms to identify which of the proposed incentives and imperfections lead to corporate hedging. We also explore the effect of hedging on the extent of asymmetric information faced by the firm. We investigate whether the derivatives use determine analysts' earnings forecasts errors. A part of our research investigates the foreign exchange exposure of French exporting firms before and after the introduction of the euro. The determinants of the estimated exposure are finally examined

Full textLicensed products (i. E the declension of literary or artistic work's notoriety and its marketing through numerous articles) destined for children are the results of a process in which cartoons shows on television promote these products. Licensed products, because they allow different cultural industries to be linked and to reach their goals (recognition and increased revenue) are also ways to communicate. At the crossroads of cultural industries and mass communication, this process is similar to advertising and organizational communication. Not studied in any of the fields of communication and information sciences, it is analyzed here through the prism of this communication process that is being played out between 4 poles : the cartoon, toy, and television industries and two state bodies : the conseil superieur de l'audiovisuel (csa, high council for audiovisual affairs. ) and the centre national de la cinematographie (cnc, national center on cinematography. ). The following main lines emerge from this analysis : 7 caracteristics of these licensed products for children ; 7 players involved in this arena and their complex relationships ; 7 other fundamental cultural, political and economic problems

Full textThis thesis examines in three empirical essays levels and changes of CDS spread related to largest European companies. In the first chapter, we aim at identifying most important variables that drive CDS spreads in normal market conditions We suggest a list of new microeconomic variables and we find there exist some remaining sector wide common factors. In chapter two, we examine credit risk spillovers of CDS and equity markets under extreme conditions. To this end, we implement among other the very recent CoVaR technology of related entities. We also find here indirect evidences that sectors govern the behavior of individual CDS. In chapter three, we finally undertake a number of event studies on CDS and Equity daily data making use of hand-collected credit rating changes. Among other things, we evidence that both CDS spreads and equity prices move as the rating changes but also that movements differ according to upgrades, downgrades, succession and turnovers

Full textIn this thesis, we analyse the problem of water shortage which concerns many countries in the world. This problem has many dimensions: social, economic and political in particular. In this work, we are interested by the economic dimension. Our objective is to give some solutions to this problem with the framework of real options. The methodology proposed in this thesis takes into count the implicit flexibility of investment projects. Multiple evaluating methods of modern finance are used to determine the exact price of real options related to water shortage problems. The Black & Scholes model and its extensions are used (Exchange option, American option, etc. ), in the special case of the option of importing water. The comparison of all result helps to give some conclusions about which technique must be used
Nguyen, Huu Adrien Hieu. "Valorisation financière sur les marchés d'électricité." Paris 9, 2012. http://basepub.dauphine.fr/xmlui/handle/123456789/10456.
Full textThis Ph. D. Dissertation deals with the pricing of derivatives on electricity price. The first part is a theoretical extension of Arbitrage Pricing Theory: we assess the problem of pricing contingent claims when the financial agent has the possibility to transform assets by means of production possibilities. We propose a specific concept of arbitrage for such portfolios in discrete time for markets with proportional transaction costs. This allows to show the closedness property, portfolio optimization problem or a super-hedging theorem. We then study such portfolios with financial possibilities in continuous time, with or without frictions. We apply these results to the pricing of futures contract on electricity. In the second part we introduce a class of models allowing to link the electricity spot price with its production cost by a structural relationship. We specify a two combustibles model with possible breakdown. It provides explicit formulae allowing to fit several pattern of electricity spot prices. Using the minimal martingale measure, we explicit an arbitrage price for futures contracts minimizing a quadratic risk criterion. We then specify the model to obtain explicit formulae, calibration methods and statistical estimation of parameters. We address in a second time the question of the risk premium associated to the holding of a European option upon a non-yet available futures contract. We essentially apply the ideas of Bouchard and al. (2009) to the semi-complete market framework and propose numerical procedures to obtain the risk premium associated to a given loss function

Full textModeling the Term Structure of Interest Rates refers to a dual problem in finance. The first one is to replicate yield curves extracted from observed bond prices. The second is to capture its dynamics. To address these issues, many models have been developed. The purpose of this thesis is to explore one of them: the Quadratic model. Quadratic Term Structure Models first assume a quadratic relationship connecting the instantaneous interest rate and latent variables describing the evolution of the theoretical economy. Second, latent variables’ are assumed to follow Ornstein-Uhlenbeck processes. Quadratic Term Structure Models were introduced to address structural problems encounter by other types of models. This thesis deepens the theoretical framework of Quadratic Term Structure Models in discrete time. We exploit these results to assess their ability to reproduce Term Structure of Interest Rates. Their use in bond portfolio management is also investigated theoretically and empirically. Finally, we study the price of a European option written on bonds within this framework

Full textCette thèse est consacrée à des techniques de réduction de variance pour l'approximation de fonctionnelles de processus de diffusion, motivées par l'évaluation et la couverture de produits dérivés en mathématiques financières. Notre principal outil est le calcul de Malliavin, qui donne des expressions simulables des sensibilités et de la stratégie optimale de réduction de variance. Dans une première partie on donne une présentation unifiée des méthodes de variables de controle et d'échantillonage préférentiel, ainsi qu'une factorisation opératoire des stratégies optimales. On introduit un algorithme d'échantillonnage préférentiel paramétrique dont on mène l'étude détaillée. Pour résoudre le problème d'optimisation associé, nous validons deux procédures basées respectivement sur l'approximation stochastique et la minimisation du critère empirique. Plusieurs exemples numériques illustrent la portée de la méthode. Dans une deuxième partie nous combinons intégration par parties et transformation de Girsanov pour proposer plusieurs représentations stochastiques des sensibilités. Au-delà du cadre strictement elliptique, on montre sur le cas d'un modèle HJM à volatilité stochastique une construction efficace de vecteur couvrant au sens de Malliavin-Thalmaier. Le dernier chapitre, de nature plus appliquée, présente un cas réel d'évaluation et de couverture d'options exotiques sur taux

Full textThe last few decades have witnessed a considerable increase in the weight and influence of finance in contemporary societies, a phenomenon that social scientists have begun to study with the concept of financialization. Financialization remains rarely studied in law. This dissertation contributes to its study by adopting a socio-legal approach: it assumes that such a transformation of social and economic relations must have given rise to controversies in the legal arena, from which one could better understand what financialization means in law. I have chosen to approach these controversies through a specific question, that of financial innovation. I took as a case study a particular type of financial instruments, which have transformed the financial landscape since their invention in the 1980s: swaps, or over-the-counter (OTC) derivatives. Based on the analysis of contractual documents crafted by the industry, of the professional literature in financial law, and of the case law arising from swap disputes, this study recounts the legal history of these financial instruments. It shows that legal practitioners, through the legal shaping of financial innovation, have not only fostered the success of the new markets for financial instruments, but have also initiated a profound transformation of business’s legal culture. Financialization thus coincides, in law, with a renewal of concepts, values, practices, instruments and modes of argument deployed by financial lawyers. I argue that, under the influence of the latter, it is ultimately the law itself that was financialized, in a way that significantly increased the legal autonomy of the financial industry

Full textLn the aftermath of the 2008 financial crisis, the authorities tackled the issue of counterparty risk associated with OTC derivatives. The ten years that have passed since then allow us an opportunity to take stock of the effectiveness of the regulatory framework then put in place. This study aims to map the different elements that make up or feed the counterparty risk in OTC derivatives and analyzes the effectiveness of the various techniques deployed to manage it. The management tools used in OTC derivatives to mitigate counterparty risk rely on a variety of legal mechanisms. If some are at the free disposal of the parties, others are imposed by the regulations. All these instruments participate -alone or jointly-in actually mitigating the counterparty risk. But each of them only deals with a particular aspect of this risk and none of them can completely neutralise it. Some situations even sometimes disrupt the effectiveness of counterparty risk management tools and negate their beneficial effects. Ultimately, it is understood that the effective management of counterparty risk requires three stages: the identification of the risks attached to each operation, followed by the development of relevant management tools with a view to the mitigation of such risks, and finally steps to avoid the risk of inefficiency of the tools used. ln any case, counterparty risk management in OTC derivatives is not only imperfect but also eminently fragile

The derivative is usually used in international tansactions, and several legislative orders are in competition to govern the contract. The rules for choising a national law are confronted with the parties’ freedom and with the financial markets’ imperatives. The markets’ stability and security are very important. Parties can chose the law applicable to the contract. But the derivative can also be contracted on multilateral system, parties are abble to take financial collateral arrangements, and others laws can be involved

Full textThe financial crisis started in 2007 has raised a number of issues including systemic risk and its regulation, and the role of derivatives in the banking sector. The thesis discusses these questions in the light of the European banking sector. ln particular, we show that the interdependence of the individual risks measured by copula functions increased significantly at the onset of the crisis that resulted in a spectacular upsurge in VaR (Value-at-Risk) of the European banking sector. We have also established that starting from 2003 the risk dependence pattern has been symmetric, that is characterized by equal probabilities of simultaneous increases and decreases of banking risk returns. ln accordance with regulation of global systemically important banks adopted in 20 Il, banks which play a significant role in the stability of the financial system should face capital surcharges. By applying game theoretical approach, we find that the side effect of such measures would be an increase in market interest rates and a decrease in loan supply. Besides regulation of systemic risk, derivatives are a matter of concern. The thesis aims at finding empirical evidence for these arguments. Contrary to the majority of previous studies that do not document the relevance of derivatives for banking efficiency, we find a positive impact of both hedging and trading derivatives on efficiency. The scale of operations with derivatives measured by notion al amounts does not increase the volatility of return in the banking sector. However, the credit risk of derivatives, especially in the case of trading contracts, proxied by positive fair values contributes to higher volatility

Full textThis thesis uses quarterly and annual data on capital market prices covering the period 2003-2009 additionally to annual accounting data during the period 2003-2010 of banks in both emerging and recently developed countries. The purpose of the thesis is to investigate empirically the effect of using derivative instruments (forwards, swaps, options and futures) on bank risk and performance. Main results reveal that in except to options the other derivative types decrease bank risk. Thus, there is no proof that derivatives can be the cause of bank failure or distress. In addition, results show that using derivatives in the whole diminish bank performance. Indeed, adjudication that derivatives are beneficial is not allowed. Finally, comparing results expose that the effect of derivatives on bank risk and performance is almost the same either in banks from emerging or recently developed countries. Ultimately, the ongoing debate on implication of derivatives in the recent financial crises should be revised
Daudignon, Sandra. "Three essays in monetary and financial economics." Thesis, Paris 1, 2020. http://www.theses.fr/2020PA01E063.
Full textThe first chapter analyses the impact of the central clearing requirement for swaps, which entered into force in 2013, on the derivatives activity of US banks. Part of treated banks, ie banks that are not eligible to the "end-user exception", reallocate their portfolio by substituting OTC interest rate swaps (regulated products) for OTC interest rate options (unregulated products). This suggests that these banks might engage in regulatory arbitrage. The second chapter allows for an integrated natural rate of interest in a new Keynesian mode! and studies its implications for optimal monetary policy under commitment. It shows that systematic increases in the optimal rate of inflation become warranted in response to downward shocks to the long-run natural rate, once this drifts below 1%. Nevertheless a constant price level targeting rule of the form put forward in Eggertsson and Woodford (2003) continues providing a good approximation to optimal commitment, as long as the long-run natural rate remains in positive territory. The third chapter investigates the link between micro-uncertainty, defined as the cross sectional dispersion of firms' idiosyncratic productivity, and the allocation of credit across firms. It analyses the equilibrium of a collateralized debt market where banks and financial investors internet in presence of adverse selection and signaling. The mode) predicts that a jump in micro uncertainty may generate a change of the information regime which may translate into a credit crunch. In this case, a high micro uncertainty restores the efficient allocation of credit as banks finance only high quality projects

Full textFrom 1970s, the questioning of the monetary system of the fixed parities causes the appearance of new risks on markets, and leads financial players to look for new techniques to master the effects: the first derivative financial instruments arise from this will. However, at the time of recognizing legally these instruments, the legislator as for him plans no precise qualification and no definition and adopts the little decisive technique of the enumeration. What leads to predict that derivatives cannot base a unitarian legal notion but constitute simply the addition of heterogeneous financial models. From then on, the research for the legal nature of derivative owes demonstrate its specificity as instrument of transfer of the full financial risk and to characterize it with regard to the other families of named contracts. Besides, if the derivative operates a transfer of risk, it turns out itself generator of a specific risk, at the same time for the parties which conclude it and for thirds in connection with the latter: by its intrinsic attributes, it is fundamentally carrying risk to the whole financial system. The necessity of recognizing this risk and of controlling it closely settles then in compelling objective

Full textThe currently prevailing position among Islamic Finance’s jurists and theorists being to prohibit derivative products in Islamic Financial Institutions, the search for an “Islamic” alternative to these products, in particular for market risks’ management, constitutes one of the fundamental axes of research concerning the future of this school and type of institutions. Thus, this doctoral work deals with the inference of the possible contemporary meanings of the Islamic concept called “prohibited Gharar” (litt. “prohibited risk”) while opposing it to the permissible risk-taking, then, based on the corresponding findings, it deals with the exploration and proposal of alternative instruments to derivatives. On the first aspect, this research used texts of Islamic Fiqh (“jurisprudence”), and mobilised qualitative and numerical tools of analysis, while drawing on Max Weber’s method of the idealtype. On the second, it implemented a survey combining literature and field study, before passing the obtained instruments through a filter constructed from the results of the first aspect. This work has mainly contributed to shed a new light on the theories of risk-taking and Gharar in Islam, to identify and discuss the shadow areas behind contemporary debates, to draw up an inventory of research on alternatives, to identify and understand a phenomenon called replication trap, and especially, to propose a general way out, using the Islamic theory of need and public interest, the idea of risk-sharing and that of alternative

Full textIn its first part, this thesis studies the optimal use of derivatives contracts for risk management by financial intermediaries, focusing especially on interest rate derivative contracts. It models the optimal capital structure policy of a bank and shows how the optimal use of derivatives affects a number of oft-studied decisions in corporate finance: bank lending, maturity mismatching, payout policy or default probabilities. The second part of the thesis, in contrast, studies derivatives market as a system on its own. The second chapter uses a new and unique dataset of bilateral exposures to CDS contracts in order to provide a detailed description of the network structure of exposures. The third chapter focuses on the regulation of derivatives markets. It studies central clearing of standardized derivatives contracts and the collateral demand induced by the reform at a global scale, under a variety of hypotheses regarding the market microstructure

Full textFollowing the financial crisis of 2007, a set of regulations was implemented, including EMIR in Europe. Among the obligations arising from this text, there is an obligation to declare to the regulatory authority all OTC transactions. The goal is to increase transparency on OTC markets. My objective is to demonstrate that this is not actually the case. For that, I explore two main axes. The first one concerns the implementation of the reporting obligation and the analysis of this data by regulators. For this purpose, I use the public data on this issue and also the private data from my work. The data are relatively well reported but not fully exploited by the regulatory authorities. The second axis is more theoretical. Information does not necessarily lead to transparency. The symmetry of information and trust between OTC’s participants are the most important
Guillotte, Delphine. "Les Equity Swaps." Thesis, Paris 11, 2011. http://www.theses.fr/2011PA111005.
Full textThe purpose of this study is to qualify and, consequently to specify the governing laws applicable to a derivative called “equity swap”.Equity swap is a bilateral contract which allows one of the parties to acquire economic ownership of some shares indicated by the parties. Those shares are called “underlying shares”. They are not due to be delivered by the parties. The parties to an equity swap are only due to pay to each other cash amounts representing values of the underlying shares. That is these very particular obligations which enable to qualify the equity swaps as derivatives.Thus, the underlying shares are used in order to calculate those cash amount so that they represent the economic ownership of the underlying shares. That is the reason why equity swaps are an original kind of derivatives.The economic ownership created by the equity swaps results in some legal uncertainty. Equity swap do not provide for assignment of legal ownership. And none of the parties is due to be the legal owner of the underlying shares. But a shareholder may enter into an equity swap in order to transfer the economic ownership of its shares and equity swaps are often used by investors in order to acquire hidden ownership in listed companies. In other words, parties do not enter into equity swaps for financial purpose only. Determining the laws applicable to the equity swaps requires to analyze companies law and stock exchange law.At last, as a derivative the equity swap is supposed to be governed by financial regulation. This regulation does not fit with derivatives. It needs to be specified

Full textArtificial intelligence has become more and more popular in quantitative finance given the increase of computer capacities as well as the complexity of models and has led to many financial applications. In the thesis, we have explored three different applications to solve financial derivatives challenges, from model selection, to model calibration and pricing. In Part I, we focus on a regime-switching model to price equity derivatives. The model parameters are estimated using the Expectation-Maximization (EM) algorithm and a local volatility component is added to fit vanilla option prices using the particle method. In Part II, we then use deep neural networks to calibrate a stochastic volatility model, where the volatility is modelled as the exponential of an Ornstein-Uhlenbeck process, by approximating the mapping between model parameters and corresponding implied volatilities offline. Once the expensive approximation has been performed offline, the calibration reduces to a standard & fast optimization problem.In Part III, we finally use deep neural networks to price American option on large baskets to solve the curse of the dimensionality. Different methods are studied with a Longstaff-Schwartz approach, where we approximate the continuation values, and a stochastic control approach, where we solve the pricing partial differential equation by reformulating the problem as a stochastic control problem using the non-linear Feynman-Kac formula

To conduct the econometric analysis, Vector Autoregressive model and Granger causality test (Granger 1988) are used. It then studies the impact of the introduction of derivatives trading market on the price volatility of physical market through an econometric study with GARCH model. Finally, it examines the potential effect of changing reforms on electricity prices and security of supply and analyses the interaction between UK reforms and EU regulation

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 textWe investigate the impact of option listing on the underlying stock dynamics and the informational efficiency of the stock market, using data from the French Euronext Paris stock market about new option listing that occurred over the period 1996 – 2006. We take into account the implementation of a new trading system after the Euronext merger with the Liffe market in 2002 and the macroeconomic changes over the period.Considering different characteristics of stocks, we observe (i) no effect on both volatility and systematic risk measured by the beta, (ii) a negative price effect, although insignificant at the majority of times, (iii) a significant rise in the volume and, finally (iv), a significant decrease in the spread bid-ask. By estimating a VAR model, we highlight a better adjustment to new information, observable jointly through contemporaneous and delayed relations between volume and volatility. However, when decomposing volatility into the contributions of informed and non-informed agents, we cannot document any migration of informed traders to the underlying stock market after option listing. We confirm the absence of impact of option listing on the underlying stock pricing efficiency by examining the stock price duration dynamics, using a modified Log-ACD model that accounts for liquidity captured by trade size.On the other hand, we show that in high volatility periods (low volatility periods), the option market plays a hedging role (speculation and/or arbitrage). The implementation of the new trading system after the Euronext merger with the Liffe market in 2002 appears to have no significant impact on the underlying stock. The global result about the absence impact of option listing is justified by the underlying stock’s volatility-driven trading. These strategies disturb the connection between option and underlying stock markets and the predictive power of option prices

Full textNowadays, since financial crisis, « credit derivatives » are famous. Born in 1990’s, they transfer the credit risk. They are speculation’s instrument or margin’s instrument. International Swaps and Derivatives Association (ISDA), and the Fédération Bancaire Française (in France), point to pattern juridical agreement. Credit derivatives include five big sort of agreement : « credit default swap » (« contrat d’échange sur le risque de crédit »), « credit linked notes » (« dérivé de crédit titrisé »), « credit spread option » (« option sur écart de taux »), « credit spread forward » (« dérivé sur écart de taux ») and « total rate of return swap » (« dérivé de transfert total de rendement »). Their variety and essence ask difficult question of juridical appreciation in many countries. In French law, credit derivatives are « instrument financier ». But this juridical appreciation is incomplete. Every sort of agreement must being individually studies

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
Lopez, Hechem Ana Margarita. "Contribution à l'étude du financement de la transition énergétique : l'exemple des centrales électriques marines au Mexique." Thesis, Paris 1, 2014. http://www.theses.fr/2014PA010284.
Full textThe complexity of infrastructural offshore projects, in particular the installation of electric utilities, as a consequence of a non-adapted legal framework applicable to both electricity and to the exploitation of the maritime space and of marine resources, as well as the complexity of bilateral relations existing between the neighboring countries of the Gulf of Mexico, should be seen as an argument in favor of the use of public private partnerships rather than traditional forms of partnerships, especially because the Mexican energy market's structure has just been reformed, giving thus place to changes in existing paradigms, in the applicable legislation and regulation and in the role of existing authorities. Nevertheless, in its current state, the Mexican electricity market remains likely to impede a free and healthy competition, situation that emphasizes the importance of preserving investors' legal security, especially in the case of complex infrastructural projects. Conceived within the framework of public private partnerships, it is proposed a financial scheme based on the use of financial derivatives having for underlying asset electricity indexes, accompanied by its legal framework conceived on the basis of European texts. In fact, because of the cross-cutting nature that characterizes the right of electricity, its study should not be limited to the mere installation of material infrastructures, but should also justify the creation of a wholesale electricity market and the setting of bases for the negotiation of new financial instruments

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
