Koh, Agnès Ryo-Hon. "La société familiale cotée : l'exemple des sociétés chaebol coréennes." Thesis, Paris 2, 2015. http://www.theses.fr/2015PA020087.
Full textFamily-owned companies contribute the largest share to our economy. Yet, there is still no legal definition of what a family-owned company is and the topic has not drawn a lot of interest from legal academics. This study aims at differentiating family-owned companies by focusing more specifically on companies listed on a financial market. Family-owned listed company combines two worlds, family and financial market, which are based on diametrically opposed values and modus operandi. This conflict helps us to understand the specific features of these companies, as well as the risks attached to them. Taking the example of the chaebol, the Korean family-owned conglomerates, we highlighted the impact of the family control on the management and the governance of these groups. We compared French and Korean companies and legal frameworks, drawing the conclusion that the French legal system might have been a better fit to the Korean environment than American rules. Our research also underlines the relative failure of the transplant of U.S. standards in South Korea, which can be explained by the theory of path dependence

Full textThis study is included in the field of market microstructure. The goal of this work is to examine market behavior around the times of public information made in the paris bourse. In the first chapter, we propose to study intraday speed of adjustement of stock prices to new information. The aim of the second chapter is to examine asymmetric information around earnings announcements. In the third chapter, we study investors' bahavior around public information. The last chapter deals with intraday relation between information flow and market activity

Full textThis thesis investigates the ethical investment products from a perspective barely approached by the literature, namely the supplier's point of view. More specifically, we focus on the strategies used by corporate promoters, and their consequences, when reating, designing and disseminating the so called "ethical" financial products. To achieve our goal, several different databases and methodologies are used. Regarding the determinants of the decision to create SR products, it seems that SR funds are introduced by corporate promoters with significant economic and human resources that allow them to communicate more extensively on their activities, to reinforce their CSR strategies or to divert stakeholders' attention from their financial difficulties. As such, we may argue that issues related to the reputation of the corporate sponsor are key to explain the decision to create SR funds. In terms of design, our results show evidence that SR screening has a rather limited impact on the variability of SR funds returns over time and among funds. Furthermore, using the case of Shariah compilant investment, we set forth that the choice of a screening norm over another has a significant impact on the final composition of ethical portfolios and, ex post, on their financial performance. Finally, regarding the dissemination phase, our results suggest that on average, the announcement of a SR fund introduction has a slightly positive effect on the market value of the corporate sponsor

Full textI begin by presenting the way New Economic Sociology advocates use the notion of embeddedness to study concrete markets. Embedding conditions are shown not just as the normative setting for decision-making but indeed as the very basis of transactions. Then, I argue that New Economic Sociology, contrary to Max Weber, neglects the existence of constraints peculiar to the capitalist market system. To demonstrate this inadequacy, I study two main French fair trade promoters, Artisans du Monde and Max Havelaar. I describe their efforts into creating the conditions of a personalisation of market transactions and of the exercise of a substantive rationality. Next, to trade against the market is not an easy matter. As fair trade promoters want to develop their outlets, they have to face market constraints and these obligations may conflict the alternatives they try to build

Full textThe volatility bursts in financial markets obviously questions their link to information. This study empirically highlights the relation between the information and the exchange process. We tackle this question under two complementary views. We initially compare several proxies of the information flow. Then, we analyze the relationships between various components of the exchange process (transactions and order book). The comparison of various information proxies suggests that the bests are in descending order: - the number of transactions; - the volume of transactions; - the number of orders; - the volume of orders. The progressiveness of these studies on the French market enables to compare the results of various methodologies. We observe that the data aggregation within intervals and the underestimation of the informational set led to a partial and skewed vision of the relationships. The organization of the Parisian market (centralized order driven market) confers a central role to the order book. It arises that agents can limit themselves to this observation since the trade features (volume, duration) do not have any more a significant influence when the effects of variables from the order book are included. The relationships highlighted between the variables stress that the main force is the liquidity supply. The periods of strong (weak) activity seem associated with the absence (the presence) of informed traders

Full textA conceptual analysis of the power of capital in a corporation involves distinguishing between legal and economic power. The legal power of capital classically refers to an organic prerogative but also has to be analyzed according to the theory of power in private law. Hence, shareholders have to exercise an altruistic prerogative for the benefit of interests other than their own. Indeed, corporate law is organized around several interests that may conflict with individual shareholder interests, for example the common interest of shareholders or even the purely selfish interest of the corporation. However, this classical theory of legal power is challenged by the doctrine of corporate governance whose current expression of economic power in corporate law can be defined as the capacity of economic entities to reduce risks. By modifying managerial conduct, this doctrine aims to reduce the risks related to the investment in listed companies. Corporate governance is a phenomenon of economic power, not legal power in the corporation. A realistic assessment of this power leads to the conclusion that it is ineffective in reducing investment risks

Full textCompanies are subject to a very substantial control. The detailed analysis of the respective functions of the various company's governing bodies, shows that in reality the management’s control and the supervision’s control join in a single definition. This definition applies to anyone related with the company’s life and allows to avoid any liability for the control carried out by people who only have a right of information. If control must be conceived as a single operation the question rises of the multitude of liability schemes which applies on the holders of a mission of control. The study of the conditions and the scheme of their liability allow to notice, beyond, the differences of scheme, the conditions of application : the fault, the damage and the causal link , are the same, whatever its ground. It is then allowed to criticize the differences of liability schemes applying on manager and supervisor and to propose to go back to some coherence by a revision, which can be qualified as small, of the liability resulting from the control

First of all, we expose the necessary concepts to understand the context in which hidden orders were created and evolve now. We also describe exhaustively the market structure of Euronext. In the second part of our work, we examine the magnitude of hidden order use for the stocks belonging to the CAC40 index. We first highlight significant differences between hidden order placement and usual order submission. Then, we test the hypothesis that hidden orders are used by informed traders to get profit

Full textThe recurrence of financial scandals since the 1970s have demonstrated the failure of the vertical mechanisms implemented to impose Corporate Governance rules using the disclosure based model. The reason for this failure is related to the evolution of the public limited incorporated joint stock company, that led, in turn, to the evolution of corporate governance problems. These problems have always been limited to the agency conflicts between shareholders and managers and to the conflicts of interest among internal stakeholders. Today, corporate governance problems are mainly related to the external stakeholders network of the company. The 2000-2001 scandals as well as the Subprime crisis have shown that the external contractual stakeholders such as bankers, lawyers, external auditors etc. Have played a major role in causing the companies involved to collapse. Since the contractual external stakeholders are gaining more power to affect the rights of internal stakeholders; and since the internal stakeholders network has a contractual basis, and finally because the contract is gaining a larger place in organising internal realtionships in the company such as through shareholders agreements, imposing corporate governance rules through contracting might be considered a better solution. The idea is to use the genius and skills of contract drafters to the benefits of corporate governance in order to strengthen the bargaining power of all internal and external stakeholders and allow them to insert corporate governance principles in their contracts

Full textIn this thesis we sought to study the problem of evaluation on options taken on stocks, and more generally that of the formation of the bid-ask spread on the monep. The study developed according to two approaches. In the functional approach, we examined the impact of transaction costs when evaluating option models. However, even if the model which includes transaction costs gives the market maker a bid-ask spread, we underlined the fact that market makers always need to determine margins which include the price for display in their bid-ask spread. In the organizational approach, we attempted to directly identify the determinant of market bid-ask spread, and consequently the cost of activity of market making on the monep. Our research shows that modeling the bid-ask spread of an option is first and foremost a problem of evaluating this option, and to a lesser extent a problem of microstructure. In addition, we have demonstrated that the liquidity characteristics of the stock market are transmitted along with their option

Full textSince financial scandals including Enron, Worldcom, Vivendi and Parmalat, transparency is at the heart of all discussions as soon as the situation requires. Thus, everyone calls for transparency. This invocation is shared by politicians, lawyers, economists, financiers and public opinion. Thus the transparency desired by all and which corresponds to the amount of information published by companies, became the privileged instrument of regulation of financial markets. Many Western countries have adopted laws to guarantee the safety of the markets and investors. In France, there are laws such as Act New Regulations Economic (NRE) of 2001, the Law on Security Finance (LSF) of 2003 and 2005 Breton law. A European level, there are also laws and the most important are the 2013 Transparency Directive, on harmonization of the transparency requirements for information about issuers whose securities are admitted to trading on a regulated market, Directive concerning the markets in Financial Instruments (MiFID) of 2014, Market Abuse Directive Abuse (MAD) of 2014 and 2012 European Market Infrastructure Regulation (EMIR). However within societies, there is a manipulation of information, orchestrating “wars” between officers and shareholders. Transparency is thus diverted from its role as first to satisfy the selfish interest of these persons. Through the manipulation of information which he is the depositary, the leader can implement policies ti keep his chair. The custodians of the control of the company shareholders, can operate a purely economic control, and will not act in the interest of society but in their heritage interest, based on a previously stopped creating value and investment strategy

Full textThe dissociation of legal form and economic substance is one of the main drivers of financial innovation. Equity derivatives allow parties to replicate the economic substance of share ownership without transferring the legal title itself. Whereas corporate law acknowledges the autonomy of the financial contract with respect to the underlying shares by granting voting and dividend rights to their sole legal owner, core principles of securities regulation are challenged by transactions taking advantage of the dissociation between form and substance. Taking a pragmatic stance, the regulator addresses the complexity of this derivative reality by grasping the economic substance of such transactions beyond their mere legal form. Recent developments in the major shareholding notification regime and the mandatory tender offer rule indicate an increasing focus on the substance of beneficial ownership and voting power in listed companies. From this evolution emerge the contours of a regulatory approach aiming to tackle the specific issues raised by financial innovation. The approach we advocate operates both ex ante at the normative stage and ex post at the enforcement stage of the regulatory process. It is an invitation to rethink the determinants of securities regulation as well as the role of the securities regulator in the exercise of its dual power to establish norms and to impose sanctions

Full textBased on the primary financing theories and considering the context of financing decisions, this study serves two purposes. On the one hand, understanding the determinants of the Moroccan corporations financial structure, and on the other hand, evaluating the impact of these corporations financing decisions on their stock exchange prices. As a first step, we verified through an econometric study, the ability of traditional determinants of debt to explain the financial structure of Moroccan corporations during regular times and during financial crisis times. As a second step, we tested the theory of conventions which states the existence of financing modes. To that end, we carried out an analysis of the main components and a top-down classification. On last time, we carried out an events study in order to evaluate the stock market response to financing decisions. Our study targeted a series of 50 non-financial corporations listed in the Casablanca stock exchange and on 16 capital increase and bond financing announcements. Results show that only a few variables, originally from the financial theory, play a primary role in the financing policy of Moroccan corporations. Thus, considering the size and financial crisis effects, the influence of these variables changes from a compartment to another, and also from a period to another. Furthermore, the final results show that the financial structure stands as a financing mode which is influenced by the financial needs nature. Thus, in regular times Autonomy is the regime that adheres to most firms in the sample. In contrast, overdraft regime is best represented in recession. The events study results suggest that the Moroccan stock market is not responding neither to capital increase announcements nor to bond announcements, and indicate that communicated information by the financing decisions are not valuable to Moroccan investors

Full textThis thesis wants to defend and illustrate the fact that theory of industrial organisation' methods can be applied in order to analyse financial intermediation behaviors and competition in theses markets. It's composed by six chapters grouped in three parts dealing with short, medium and long-run competition. The first chapter called - concurrence bancaire et asymetrie d'information- proposes a theorical model of banking competition based on a asymmetric information between banks about borrowers's probability of payment. This model shows that credit market efficiency mainly depends of the time banks need to make rational expectations on these probabilities of payment. The second chapter tries to analyse the behaviour of french mutual funds (sicav) subscribers. This econometric study shows the law accuracy of risk - return variables, and let a great importance to the size of the sicav as a good indicator of clients's ability to anticipate correctly returns of different categories of mutual funds. The third chapter proposes a sequential games model of banking competition which tries to analyse how short, medium and long run competition can be articulated. It completes rochet's paper (1992). Numerical simulations of this model are given in chapter 4. Chapters 5 and 6 deal with long run competition between financial intermediaries and evaluate the role played by the technology. Theses chapters proposes estimations of multiproduct cost functions in banking and mutual funds industries by using a ces-quadratic form (Roller (1990)

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

Full textTheoretical formulations relating to the firm finance, developed in the USA, generally raise the problem of firms financing in terms of determining optimal policy. While these theories are relatively consistent in economies where negotiable securities market is predominant, they are to be considerably amended in economies in which the main source of firms financing is the bank credit. The link between the physical growth of the capital and its mode of financing shows then two principal ways of apprehending the financial behavior of the firms. This leads us to wonder which one of the two configurations applies or at least fits to the functioning of a developing economy like morocco, for instance. Our empirical study has demonstrated that the cash-flow inadequacy of the Moroccan firms and the deficiency of the financial market make the banking system the central axis of the accumulation and the monetary creation the necessary instrument of the production continuity. It's then a question of detecting where do exactly lie the obstacles in the way of using an auto-economy model likely to explain the functioning of an overdraft economy

Full textIn financial literature, within the context of financial markets, a signal enables the management to raise an asymmetry of information between the firm and outside investors, as this asymmetry can entail an undervaluation of the company. The dividend, ashare buyback and a debt rank among the most studied and well-known signals that can be used by managersof undervalued listed firms. Through models and numerical examples, and a qualitative study, we aim at assessing the relative efficiency of these three particular signals. To achieve this goal, we specify three criteria of efficiency : the optimal intensity, the benefit/cost ratio, and the probability for these operations to be as signals by the firms and to be interpreted in this way by outside investors. Our main results are the following anes : a debt stands for the worst signal, whatever the criterion used, and a share buyback wins the battle when we refer to the criterion of intensity, and also to the benefit/cost ratio, but only for the best firms on a short term horizon. The ordinary dividend stands out above the other alternative signals in other cases, except for the benefit/cost ratio criterion, on a long term horizon, as the extraordinary dividend wins

Full textAccording to theorists of the transparency who of any disciplinary horizons cry out the virtues, the financial information permits the balance by remedying the asymmetry of knowledge between the company and his management on one hand, and the addressees of the financial information on the other hand. The transparency raises the veil, fights the opaqueness, permit the decision and thus, the game of the market. The economists speak then about “informative efficiency” because the fluid and fast circulation of the flows of information in origin or in the direction of all the actors of stock markets (company, management, operators, shareholders, authorities of regulation, press …) would permit to supply all the time the best possible valuation of listed companies considering the publicly available relevant information. For these reasons, many reforms were operated these last years in order to increase the obligations of information towards listed companies. However, we have to admit, in view of the last financial crisis that markets can not work effectively and estimate correctly the fundamental value of a financial asset while the information relative to the underlying asset is widely broadcasted. From there, we have to ask the question of the relevance of the listed companies’ transparency

Full textCommercial companies are inescapable instruments of the modern capitalistic regime. The importance of commercial companies has especially demonstrated in their developments, by the international expansion of theirs social activity. The development of commercial companies on the international plan, produce the original problem that having their sources in the determination of the applicable law to the functioning of the company in a broad sense of the term : administrative and financial aspect of the functioning of the company. Indeed, the commercial company is essentially an economic entity whose good functioning demands an appropriate financial power. More, it is an organised economic entity since the surviving of the commercial company necessitates an efficient and punctual organisation. The originality of these problems on the international plan confers them a undeniable interest of the viewpoint of the juridical speculation. It allows in the first place, to verify the position of french law about the functioning of the commercial company and to analyse then the part of the principles of the conflict of laws and, to see if the application of the law of the head office : la lex societatis suffers exceptions, or well if this principle erases ahead the attraction of "lex mercatoria". The necessity of maintain the permanence and the unity of the juridical status of the company, confer to the law of the head office : la lex societatis, an area of application extra-territorial. But this principle of extra-territorialist must be limited in the interest of thirds. The protection of thirds party limit the extra-territorial status of the commercial company. This limitation is according to the reality of trade international that tends to protect the interest of thirds and to insure the security in the international trade on the one hand, and to safeguard the good functioning of operators of the international tradeon the other hand. In this study, we will demonstrate this contemporary tendency that consists in conciliate needs of the trade by conferring to the company an extra-territorial status, and the necessity of the protection of the interest of thirds in commercial relationships that translated in the territorialism or in the universalism "lex mercatoria". This conciliation dominates the study of the different conflicts of laws that make born the various aspec of the functioning of the company, conflicts whose examination will be distributed in two devoted parts to "the applicable law of the financial aspect of the functioning of the commercial company and to the applicable law to the administrative aspect of the functioning of the commercial company"

Full textThis thesis studies the role played by regional stock markets as well as their functioning between 1800 and 1945, in particular the Lyon Stock Exchange. The analytical framework draws on the literature on competition among stock exchanges. The thesis is structured in five papers. Chapter 1 deals with the creation of regional stock markets during the mid-nineteenth century, i.e. nearly 40 years after the reopening of the Paris Stock Exchange. The second and third chapters address the first aspect of the competitive dynamics between stock exchanges in France, i.e. the competition on issuers, and provide two measures of financial development: the number of companies listed on each stock market between 1870 and 1913 and the number of IPOs between 1898 and 1909. Chapters 4 and 5 deal with competition on stock market activity, i.e. on orders received by stockbrokers. While Chapter 4 is devoted to the end of the nineteenth century and and focuses specifically onthe crash of the Union Générale, Chapter 5 adresses the two World Wars. These two chapters offer two measures of stock market volumes

Full textThis research examines the question of explaining better the equities’ returns, taking into account the complexity of the behavior of the market in general and of the individuals in particular. The work is focused on asset pricing models conditionally to the predetermined variables and to the nature states, present in the French market. Thus, preoccupations about the applications and the empirical tests of these asset pricing models have been studied. This research also takes account of the heterogeneous beliefs of the individuals and in particular their behavioral biases in order to explain their influences on the prices and on the equities’ returns. Time series and cross sectional regressions as well as models of the GARCH and VAR types have been completed. The research done within the framework of this thesis led to many results about equities’ returns on the French market

Full textListed companies are a world apart. There are approximately 5 000 companies listed on the regulated markets of the EU stock exchanges. Although they represent less than 1 % of the European businesses, their market capitalization amounts to more than 70 % of GDP. Because they have a systemic importance for the economy, the comprehension of their legal regime is crucial. We first establish the boundaries of the applicable law, starting from the supranational level because EU law represents the most important source of both convergence and divergence. This method allows us to establish if the supranational level should extend to new areas of regulation or push for further the harmonization in the areas already regulated and to make predictions regarding the probable or desirable future directions of the regulations. We then analyze the causality of convergence, which shows three main types of convergence : imposed, by pressure and by approximation of the factual circumstances of the environment in which EU listed companies operate. We conclude that presently there is a convergence of national regulations applicable to EU listed companies despite only partial harmonization at the supranational level and that this convergence will deepen as a result of its forces and factors of causality. This conclusion reinforces the arguments for a reorganization of national laws based on a new summa divisio between listed companies and non-listed companies

Full textThe introduction of informational asymetry in the exchange process justify the apparition of "non perfect competition phenomena" which reflects the existence of strategic behavior among investors. In this case, informational asymetry leads to a cost equivalent to the lack of "informational liquidity" which effects on welfare constitute a new constraint to the optimization process of informational policies and to the stocks valuation. In fact, proofs related to the existence of a link between the information and the level of liquidity bring us to define the reasons why the firms disclose informations. Thus, beyond the organisational transparency of financial markets, firms might manage the informational gap (the cost of informational illiquidity) using their practice of disclosure (legal obligations and facultative informations). The investigation realized over fifty listed firms in the french stock market allows us to detect the existence of five informational practices. Computing the informational liquidity of each of questionned firms, we can first and foremost, verify the hypothesis supposing that this measure is an increasing level of information. Secondly, according to the principle which says that informational policy effciency could be measured by the comparaison of value improvement to the used budget, we conclude that only one of the five informational groups is more efficient and well use his informational budget. Contrary to known ideas, the more informationaly liquid group does not necessarly optimize the welfare of investors

Full textThe impressive evolution of industry management over these past fifteen years, including by the use of the techniques for managing and funding innovative and the use of more structured products increasingly complex, has led the industry and of UClTS to live profound changes. Indeed, the public nature of the collective savings and the strategic role of UCITS in the pipe to the productive sector, led the legislature to entrust the control of these agencies in various organs. Efficiency, productivity and transparency are the watchwords of our days in the financial community. All operators are obliged to implement the more relevant and more stringent rules to win this battle. The study of the control of the UCITS, returned to obscure one of the fundamental principles of the financial markets : the need for security and confidence. Indeed, investors commit in financial investments, that if the proposed products offer sufficient guarantees. This trust can be established by the control exercised over thcse last, this control is regulatory or legal, is the Commissioner of accounts, just as classical organ of the companies, the internal control as UCITS asset, the depositary as original body of the latter and finally the body key to the protection of the financial markets is the supervisory authority
