Full textThe purpose of the regulated halts on stock exchange markets is to spread the information on the market and to protect the interests of the small shareholders. Thus, the main objective of trading halts is to reduce asymmetries of information and volatility. The aim of this work is to empirically investigate the trading halts on the French stock exchange (trading reservations and suspensions) market. To this end, we proceed to a detailed statistical study in order to analyze the impact of such halts on the main market parameters (returns, volatility and volume). Our study concerns intraday data relating to securities that belong to the CAC40 stock index over the period January 1998-December 2001. It shows that the trading reservations are much more numerous than the suspensions and there exists a parallel between the frequency of the reservations and the high magnitude of the crises. Finally, we put forward a mitigated effectiveness of the trading halts, depending on the period (before or after the 04/23/2001 reform)

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

Full textThis dissertation examines voluntary risk disclosures utility on French market. Empirical studies carried out in this research test short and long term effect between risk disclosures and information asymmetry. Short-term study shows that only operational and interest rate risk disclosures reduce investor disagreements about firms’ risk exposures. Quantitative disclosures are more likely to reduce investor disagreements. These disagreements are measured by transactions volume and seem to be less important for firms listed in the US market in which firms disclose more about their risks. We conclude on the existence of short-term effect of risk disclosures level. Throughout long-term study, we measure risk disclosures level for French market listed firms during three years. We examine the impact of this level on financial analysts’ forecasts. Our findings show no significant relationship between risk disclosures level and financial analysts’ forecasts errors and dispersion. However, disclosures level of reports issued by French firms reduces analysts’ forecasts errors and dispersion

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 textMarket concentration is often considered as a better mean for liquidity improvement. However, the needs expressed by traders in term of cost of trading, liquidity and rapidity of execution make trades more fragmented and stock markets segmented. These mutations are expressed through the alternative electronic trading systems (ATS and MTF) which have radically altered investors' practices. In Europe and more specifically in the London Stock Exchange (LSE), regulation is concerned that such competition is the best way to improve market quality. The novelty of this research is based on the LSE particularity. In fact, the LSE is one of the stock places based on both electronic (SETS) and quoted-driven (SEAQ) markets. Three objectives are discussed in this thesis. First, we study the effects of the crossing network POSIT on the LSE transaction and adverse selection costs. Does POSIT improve, or inversely, reduce the LSE competitiveness? Secondly, we observe informed traders' behaviour and the kind of stock that they use on both SETS and SEAQ markets. Finally, we analyse informed traders strategies and the trade size which they use in order to make the private information profitable

Full textThis thesis deals with the theoretical and empirical analysis of financial integration of capital markets. The first part is a review of the literature about the phenomenon. The first chapter presents, defines and measures financial integration. According to the law of one price, two assets which have the same characteristics, but which belong to two different countries, are integrated if they have the same expected return. This implies that the risk premia associated with international (common) factors are identical. The two following chapters present a re, view of the literature about financial integration in the context of two asset pricing models, which constitute the paradigm of the theory of international finance: the capm and the apt. Also, this part allows to study the impact of barriers to investment on the choice of portfolios, and to examine different forms of partial integration, i. E. Segmentation by zone, by access cost and by agent. From this review of the literature, an ambiguous conclusion emerges, showing that the degree of integration is variable according to the markets, the periods and the ap, proaches considered. The objective of the second part of this work, is, therefore, to empiri, cally examine the hypothesis of financial integration as well as its evolution during the period 1973-1995, with regard to a sample of 230 assets. To do so, it is necessary to check that the arbitrage transactions lead to the equality of the returns of assets which present the same char, acteristics. These studies are realised in the context of two theoretical models: the capm and the apt. The results obtained do not confirm the hypothesis of integration of the six markets studied during the period 1973-1995. This result holds, whatever the model used. Finally, as regards the evolution of the degree of financial integration, the results do not confirm the hy, pothesis that markets are nowadays more integrated

Full textThe history of the stock market is marked by a number of significant scandals and crashes. The crashes of 2007-2008 and 2010 became a public debt crisis and called into question the advantages and disadvantages of the current global financial system. The objective of this thesis is to analyze the market anomalies in general and those of the French stock market in particular. We try to answer the following questions: Does the efficient market hypothesis still hold true? Which anomalies exist in the financial markets? How can we explain the sources of market dysfunction and what are the natures of these deviations in relation with the market fundamentals? What are the consequences of market dysfunction and what would be the effects on stock prices? The contribution of the work comes from its ability to explain the failure of the financial markets through the study of market microstructure and behavioral finance using a Keynesian theoretical framework. In addition, we analyze the theory of efficient market and the standard empirical approaches to test the concept. We then try to identify the limits of the theory and observe recent market anomalies that have revived the controversy around standard financial assumptions. We propose both macro and micro economic explanations for the observed deviations. Finally, we justify our use of non-linear processes to better understand stock price dynamics

Full textIn financial matters, the general theory of the sources, which is the key understanding of the law and the legal system, does not appear to be fully operative. The institutions usually identified by the classical presentation of the sources of the law within the national legal systems and the European Union - legislative, executive and judicial institutions - are not the only entities involved in the establishment of the financial legislation. In this configuration, it is necessary to confront the classical presentation of the law with the production circuits of the financial legislation. The comparison between the traditional scheme of the sources with the modes of production of the financial legislation reveals the singularity of the financial legislation. The authors of financial legislation seem to distant themselves to some extent from classical sources of law. Original authors work along with classical sources on the conception of the financial law. This includes national and European regulators, market infrastructure managers and professional associations. The intervention of such entities is justified by their ability to respond more effectively to the characteristics of the financial markets. The interaction between these original authors and the classical sources of law makes the production circuits of the financial legislation quite singular compared to the classical presentation of the sources. Thus, financial law reveals an adaptation process of the creation of the law in order to take account of the characteristics of the object it regulates. This singularity demonstrates the need for arranging the classical presentation of the theory of the sources and brings new considerations on the recasting of the general theory of the sources

Full textSince decades, energy prices are subject to increasing volatility affecting the whole economy. Compared to other commodity prices (for example precious metals and agro-industrial), energy price dynamics appear to be extremely uncertain both at short and long run. In a global economic context, this phenomenon is very important since intense variations of commodity prices can be tragic to real economy. This thesis focuses on the true nature of these movements. More formally, we investigate the commodity markets’ financialization, as well as the relationships between commodity and stock markets by unifying the fields of energy economics, econometrics, finance and psychology. This analysis is based on three themes: first energy prices relationships and their financial properties are analyzed, and then the behavioral and emotional specification of energy markets are studied, finally comovements between stock and commodity markets’ volatility are considered

Full textDespite the number of studies that have been carried out on the stock markets, very few studies in particular look into the analysis of the tendency of herd behavior of countries at the heart of the European Union. For that reason the emphasis is traditionally put on Asian countries and the United States. The detection of the mimicry phenomena is particularly made with subjective or extrapolative techniques. Consequently, our study is relevant on two levels since that, on one hand, it focuses on European countries and, on the other hand, it aims to verify the existence or non existence of the mimicry phenomena according to three methods elaborated first of all by (Christie & Huang, 1995) and (Gleason, Mathur, & Peterson, 2004) then by (Chang, Cheng, & Khorana, 2000) and (Demirer, Rýza; Kutan, Ali M, 2006) and finally by Hwang & Salmon (2000, 2004, 2008)

Full textThe attention paid by financial justice to local public markets is not new. previously, before the creation of the regional audit chambers in 1982, financial control of local procurement was shared between the court of auditors and the general paying treasurers. But the system adopted in 1938 was criticized because the t.p.g. brought together the two qualities of agent control and subsidiary responsible for the irregularities he discovered. This system appeared more consistent with the principles introduced by the law of decentralization of march 2, 1982, who created the CRC which was taken in the control of the local procurement. In 1982, three traditional missions had been entrusted to the CRC in the area of public procurement: judgment of auditors, review of the management and budgetary control. following a legislative reform made by the law of february 6, 1992, a fourth allocation had been assigned: examination of the conventions relating to public procurement and the dsp. Long, financial magistrates, for lack of time and means have always favored control of the regularity of procurement and enforcement of public procurement at the expense of their quality (effectiveness) control. To adapt to the new dynamics of the local public management, the magistrates of the CRC are approaching, today, anglo-saxon methods that analyze the quality of management through three criteria, so-called "triple-e": economy, efficiency and effectiveness. If control of the regularity of public procurement remains indispensable, it must now be associated with the control of performance and results

This study analyses each government's policy in these four nics) with regard to the internationalization of the capital market and explores the reason why these countries opened their capital markets. It also examines problemes encountered ind opening nic's capital markets to foreign participation and suggests the methods which make it possible to accommodate the liberalization of capital markets. Furthermore, this study presents an empirical study on the effects of the portfolio diversification in nic's capital markets. This study is divided into three parts. They are follows : part 1 describes the evolution and the structure of each nic's securities markets since their creation and analyzes concepts of the liberalization of capital movements and its effects and problems. This part gives a theorical background about the nic's securities markets and its internationalization. Part 2 analyzes the process of internationalization of the capital market in each four nics and examines the effects of international portforlio diversification in nic's capital markets. Part 3 suggests the methods to cope with problems enountered in opening nic's capital market to foreign participation before the nics can open their market completely

Full textThis thesis is made of three independent essays from a common purpose: structural dynamic modelling in financial econometrics. The first chapter leads to understand trading frequency under asymmetric information. In a Kyle (1985) framework, we assume that the liquidity shocks are not frequent. We characterize all the perfect Bayesian equilibriums. In particular, we prove that the insider can choose to not trade which influences the trade frequency. We extend this analysis when the volumes are heterogeneous. The second chapter addresses the issue of robustness with respect to both temporal and contemporaneous aggregations as well as marginalization. We introduce a class of conditional volatility models, including all models where the variance is linear (Garch, factor models), and we show that it is robust. We prove that our class is better than the weak Garch in both financial and statistical interpretations. Links with continuous time modelling are established. This chapter paper addresses the issue of estimation and testing semi parametric time series models specified by their conditional mean and conditional variance. The distinguishing feature of our approach is the systematic use of two-stage least squares procedures to determine estimators with minimum asymptotic variance in given classes. These optimality properties are obtained by a suitable appraisal of conditional skewness and kurtosis. Instrumental variables interpretations and regression-based diagnostics for heteroskedasticity are provided

Full textThis thesis aims to examine the relevance of the application of fair value in the banking sector. First of all, we study the reasons for having banks in economic life. The objective is to highlight the particular characteristics of the bank's evaluation and the need of having rules which correspond to it. Secondly, we analyze the fair value as a new method of evaluation. The analysis is focusing on its appearance on the accounting standards IAS/IFRS, its advantages and disadvantages and the results of the various empirical studies testing the informative content of the fair value and its impact on the regulatory capital. The first step of our empirical research consists of a qualitative study undertaken on the various texts published by the French Banking Federation. The objective is to specify the reasons for which the French banks are opposed to the application of fair value such as it was proposed by the international standards. In the second step, a quantitative study is realised with the financial analysts appearing in the directory published by the French Company of Financial Analysts. The results obtained show that the fair value, whatever its application level, has a positive effect on asymmetric information and the prudential constraints. This has a strong effect on the financial instruments which have an active market

Full textThis thesis is devoted to the detection and modeling of nonlinearities inherent to stock returns data generating processes. Justifying the presence of threshold effects on financial markets by transaction costs, we consider a particular class of nonlinear models : smooth transition regime switching models. We start by estimating models with nonlinearities in mean like STAR processes (Smooth Transition Auto Regressive) on G7 countries stock returns. In addition to standard linearity tests, we perform several tests that are robust to heteroskedasticity and outliers. We also apply misspecification tests. We then compare out of sample prediction performances of STAR model to other linear ones, using dynamic bootstrap methods. Moreover, going further the simple univariate context, we analyse the asymmetric effetcs linked to the magnitude of stock prices spreads and to the transition speed from one regime to an other. To this end, we estimate an STECM model (Smooth Transition Error Correction Model) with an error correction term taking into account structural changes relating to both the domestic market and the benchmark. Finally, we combine nonlinear models STAR in mean with nonlinear models in variance like asymmetric GARCH (Generalized Autoregressive Conditional Heteroskedasticity) processes. We use this type of model to highlight simultaneously asymmetric fluctuations in stock returns and risk

Full textIn a first chapter, we study the meaning of financial markets in an uncertain world with ithe specification of the whole set of the states of nature. The question is to know if financial markets could help to reduce uncertainty and help to reach efficiency conditions. The same questions are asked in chapter two and three which are about temporary equilibrium and intertemporal incomplete markets. The conclusions are that, in every kind of economy, financial market do not lead to efficiency (first order or second best). The study is focused on the implications for investment choices of the firms in such a situation. It appears, in most sophisticated models of incomplete markets that a knd of social planner with large control about investments is necessary. Chapter four is dedicated to study the case where the bank system could be substituted to this omnipotent social planner. Three models are presented which bear upon : - the monitoring of a firm by a bank, - the choics of investment by the bank system with heteregeneous anticipations, - the ways by which the bank system could inform investors. In this aim a model of signaling is built

Full textOur purpose is to study the efficient capital market hypothesis, in the case of the French stock market. We analyse the weak form and the semi-strong form of this hypothesis on the French market using intraday data on the January 1999 to December 2000 period. We retain firms that belong to CAC40 and MIDCAC indexes. In order to test the presence of a dependence structure in stock returns, we apply three tests : Box-Pierce tests, the run test and the variance ratio test. Obtained results suggest that it is impossible to predict future returns from past returns, which is consistent with the weak form efficiency hypothesis. In order to quantify the response of the market to a public announcement, we apply the methodology of event studies. Our results are consistent with the semi-strong form efficiency hypothesis

Full textSince the 1980's, deregulation and liberalization of capital markets have energized of an expansion of investment opportunities for international investors, led mainly by the stock markets of emerging South-Eastern Asian, South-Eastern American, South African, Middle Eastern and Eastern European Country's. From this point of view, as an emerging stock exchange, the Istanbul Stock Exchange (ISE) has rapidly been essentially as an attractive alternative in terms of investments and portfolio diversification for the Turkish and international capitals. Becoming an attraction pole for the world-wide liquidity the ISE deserves special attention in terms of academic research. This is precisely what is proposed in this research by presenting a complete theoretical and empirical lighting of the recent development of this stock exchange. In conjunction to a presentation of the efficiency theory, the long memory process and the dynamic of groups, intented to a better understanding the operational environment of emerging financial markets, three empirical studies are realized to test empirically these three aspects of their development, by considering specifically the Turkish emerging financial market as the empirical support. At the conclusion of empirical tests, the ISE appears as the image of other emerging stock markets, such as: rejecting of the random walk hypothesis ; presenting a long memory ; presenting herding behaviour. Despite its attractiveness, the ISE has some difficulty in acquiring long-term stability and continues to be regarded as an stock exchange which should be approached with caution, and where there are regularly observed important variations in volatility

Full textThis research contributes to the market microstructure theory. The first chapter is a survey of the vives model (1995) and the models of sales of information. The second chapter studies the preopenning mechanism of continuous systems. In the vives (1995) model the agents observe only one signal before the beginning of the game. We extend this model to the more general case in which agents observe a sequence of signal during the game. In this case learning takes place more quicker. In the third chapter, the case of a financial intermediary who is engaged in proprietary trading and at the same time manages a fund for a client (indirect sale of information) is analysed. Optimal contracts allow the financial institution to commit itself to adding noise into prices and enhance the profitability of its own proprietary trades and the fund's trades. The last chapter generalises the latter case to an oligopoly of sellers of information. In this context the Grossman and Stiglitz (1980) paradox is reversed : with no cost of information prices reveal no information at all. Finally, the sellers' aggregate expected profits goes to a positive limit when the number of sellers goes to infinity

Full textThis paper aims at giving a more comprehensive understanding of the way the prices are set up on option markets. Prediction models are derived. To facilitate their understanding we propose to split price formation process into two phases: -a first one which says how an equilibrium can be reached taking into account the way opposite operators see the future market movements and why some equilibrium can be reached or not. -second, based upon the information revealed by active operators, when enough information is given along time, we show that it is possible give probabilities of market tendencies. This will lead to a behavioral financial model build in the context of utility theory and stochastic dominance, leading to a better understanding of capital markets and option markets. . The purpose of the model will be to permit high probability forecasts in some few specific situations. For this, information coming from buyers as sellers is exploited, each operator bringing his own particular vision of future price market movements

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 textThis doctoral thesis aims at studying the information risk premium on financial markets from a theoretical, an empirical and a practical point of view. Theoretically, this thesis introduces a new rational expectation equilibrium asset pricing model for asymmetrically informed investors. Our model enables us to analyse the information risk premium in a general case, taking into account many risky assets and several sources of correlation between them. The model specification allows us to draw many new interesting theoretical conclusions and empirically testable hypothesis. Our model can also be applied on several ways. For example, the model permits explaining some market « anomalies » and phenomena in international finance. The goal of our empirical study is to test the presence of an information factor on the financial markets and to analyse the weight of this factor. The information factor is approached by a new asymmetric information measure directly founded on rational expectation equilibrium models in asymmetric information. We analyse the impact of the information factor on stock returns and show that investors require an information risk premium to hold assets. A second empirical analysis in the thesis studies mutual funds performance and their degree of specialisation as functions of the asymmetric information degree of their assets. Our empirical results corroborate the conclusions of our theoretical model

Full textMost of the financial markets theory is essentially linear : usually, dynamic financial models are described by linear stochastic differential equations. However, there has been a surge of interest for some very important problems raised by non-linear dynamics. This thesis aims at studying partial and general equilibrium schemes which take into account of these phenomena, particularly, the presence of sudden changes of volatility over time. The work is splitted into two main parts : econometric theory and economic theory, the econometric part is devoted to fill a gap between econometric models with stochastic volatility and arch models. The main argument is the analysis of univariate arch models when the time-scale i s very fast; we show in particular the weak convergence of a fairly general class of arch models towards stochastic differential equations when the sampling frequency is faster and faster. This allows us to uncover some important properties of arch which were not yet known before. The economic part exploits these results in order to build up new contingent models in continuous time. These models belong to the stochastic volatility literature. Closed form solutions are found for some of these models, and a particularly convenient procedure is proposed for their estimation

Full textHow do organizations working in a simultaneously complex, competitive and turbulent environment manage risk ? Most traders buy and sell over a hundred million dollars daily, and there arc more than one hundred operators on a dealing floor. This empirical study draws over three years of participant observation in a trading room and forty interview in Paris, London and Hong Kong. There are three main contributions to this research : 1. The development of concepts guiding the understanding of the unique phenomenon of dealing rooms : the position, the correlation of financial instruments and the desk as a combination of a trading strategy and a product. 2. The building of a model guiding the understanding of organizations. This model is based on three fundamental forms: the hierarchy, the market and the network. We redefine them as ideal types through regulation, coordination and adaptation. 3. These ideal types allow for an analytical charting encompassing risk-management strategies. This makes it possible to draw up a falsifiable hypothesis: are trading rooms plural organizations ? We show the relevance of our ideal types and of their complex interactions. Chinese walls and product lines are explained as an application of this approach. Some distinctive features of dealing rooms are also explained : their perpetual state of transformation and their distinctiveness from other forms of organization. Facing a "crisis of the understanding of organizations", we suggest a new approach to risk- management and bring a contribution to the question of the "nature of the firm". Parallels with other organizations - in simultaneous engineering, control towers and news agencies - are suggested. Teaching of our research also bear on the inadequacy of risk-control strategies in use and suggest ways of improvement

Full textThe prevailing instability in the financial markets legitimizes a clear improvement in the methods of the current regulators. Indeed, the new dynamic proposed in the thesis is to consider markets as a place of wealth creation and not insecurity. How to achieve this goal? By the conjunction of two approaches: the first approach is the one that advocates the adaptation of classic instruments of recovery (Part I), namely the standards from one side (Title 1) and the institution from the other (Title 2). Nevertheless, being outpaced by the technological evolutions in the markets, this adaptation is only the substrate which should allow a second step to emerge, a step of prospective security (Part II) by both technology (Title 2) and against technological threats (Title 1). Thus, the adaptation of classic security combined with the introduction of a prospective security are the two pillars suggested for securing the financial markets

Full textThe subject of this thesis is a comparative study of futures commodities regulation in France and USA. An introduction and a preliminary chapter relate the emergence of futures markets and the evolution of their regulation in the two states, clarify the meaning of various notions and remind the main functions of these markets. In an indepth analysis of french and american futures markets institutional frame, are successively tackled, in the first chapter, the matter of States supervision on markets, other regulation and supervision bodies, and markets organization, while a second chapter reviewes various market's agents by clarifying the frame and terms of their intervention. The last two chapters are devoted to the analysis of the differents markets' transactions : first, are explained, in the third chapter, mecanismes, methods and technicals to carry out various markets cealings, the list of differents market's operations, typology of market's orders, the way to produce them and the various rules of market's negociation used on french and american's markets places. Lastly, the fourth chapter presents the means of settlement of operations through an analysis of clearing and settlement processes

Full textThis thesis is devoted to the link existing between bayesian learning models, human being's processing of information and financial markets' information (in-)efficiency. The first part focuses on the herding literature to prove that a rational processing of information may be sufficient to prevent phenomena of exuberance on financial markets. The second part concentrates on the contribution of cognitive psychology literature and of bayesian learning models to behavioral economics. This analytic frame provides a formal and wellstructured definition of rationality. This allows a certain kind of irrationality to be highlighted from a clear benchmark. The main contribution rests on a bayesian updating model of subjective beliefs where agents process their information in function of the nature of the information they dispose of
