L'atteinte à la transparence des marchés financiers : l'exemple du délit d'initié : étude comparée du droit français et du droit libanais / Affecting transparency of financial markets : example of insider trading

Ibrahim, Majida 25 September 2015 (has links)
Le délit d’initié peut être légal ou illégal selon le moment où l’initié fait le commerce : il est illégal lorsque l’information est non publique. Effectuer une négociation tout en ayant une connaissance particulière est injuste pour les autres investisseurs qui ne disposent pas de l’accès à ces connaissances. Les dirigeants ne sont pas les seuls à être reconnus coupables du délit d’initié. Des gens comme les courtiers, et même les membres de familles peuvent en être coupables. Par contre, le délit d’initié est légal une fois l’information a été rendue publique, au moment où l’initié n’a aucun avantage direct sur d’autres investisseurs. La tendance est à la pénalisation du délit d’initié ainsi qu’à la création d’une autorité de régulation spécifique aux marchés financiers. Ce travail s’appuie donc sur une étude des différents systèmes juridiques répressifs qui tendent à assurer la transparence des marchés et veiller au respect de l’égalité entre les opérateurs par le phénomène de la régulation. On s’attachera dans une première approche à l’originalité de l’infraction, à savoir la double définition qui engendre une double poursuite : pénale et administrative. Et dans une deuxième approche, on analyse la question de l’effectivité du dispositif répressif instauré, dans lequel nous concluons que cette dualité de système répressif face à la règle non bis in idem ne peut être comprise que comme une cohérence et une complémentarité entre les deux ordres de juridictions qui forment une avancée en particulier / Insider trading can be illegal or legal depending on when the insider makes the trade: it is illegal when the material information is still non public, trading while having special knowledge is infer to other investors who don’t have access to such knowledge. Directors are not the only one who has the potential to be convicted of insider trading. People such a brokers and even family members can be guilty. Insider trading is legal once the material information has been made public, at which time the insider has not direct advantage over other investors. The tendency is to the criminalization of insider trading and the foundation of a specific regulatory authority for financial markets. The work is therefore based on a study of different law enforcement jurisdictions which trend to ensure markets transparency and ensure the respect of equity between the operators by the phenomenon of regulation. In a first approach, we study the originality of the crime including the double definition that generates a double prosecution: criminal and administrative. And in a second approach, we analyze the effectiveness of the repressive system in which we realize that this duality of the repressive system facing the non bis in idem can only be seen as coherence and complementarily between the two orders of jurisdictions

Pricing and hedging strategies in incomplete energy markets / Valorisation et stratégies optimales dans les marchés incomplets de l’énergie

Ménassé, Clément 11 July 2017 (has links)
Cette thèse porte sur la valorisation et les stratégies financières de couverture des risques dans les marchés de l'énergie. Ces marchés présentent des particularités qui les distinguent des marchés financiers standards, notamment l'illiquidité et l'incomplétude. L'illiquidité se reflète par des coûts de transactions importants et des contraintes sur les volumes échangés. L'incomplétude est l'incapacité de pouvoir répliquer parfaitement des produits dérivés. Nous nous intéressons à différents aspects de l'incomplétude de marché. La première partie porte sur la valorisation dans les modèles de Lévy. Nous obtenons une formule approximative du prix d'indifférence et nous mesurons la prime minimale à apporter par rapport au modèle de Black-Scholes. La deuxième partie concerne la valorisation d'options spread en présence de corrélation stochastique. Les options spread portent sur la différence de prix entre deux sous-jacents -- par exemple gaz et électricité -- et sont très utilisées sur les marchés de l'énergie. Nous proposons une procédure numérique efficace pour calculer le prix de ces options. Enfin, la troisième partie traite de la valorisation d'un produit comportant un risque exogène dont il existe des prévisions. Nous proposons une stratégie dynamique optimale en présence de risque de volume, et l'appliquons à la valorisation des fermes éoliennes. De plus, une partie est consacrée aux stratégies optimales asymptotiques en présence de coûts de transactions. / This thesis tackles three issues on pricing and hedging in energy markets. Energy markets differ from financial markets mainly in two ways: illiquidity and incompletness. Illiquidity (or lack of liquidity) translates into transaction costs and volume constraints. Incompletness means incapacity to perfectly hedge derivatives. We study different aspects of incomplete markets. First, we focus on indifference pricing in exponential Lévy models. We obtained an approximate formula by considering a Lévy process as a perturbed Brownian motion. That way we obtain the minimal correction from Black-Scholes price. Second, we present a numerical procedure to price spread options when underlyings are stochastically correlated. These options are very popular in energy markets, underlyings being for instance gas and electricity. Third, we derive optimal strategies using exogeneous factors forecasts. We exhibit an explicit pricing formula and an optimal strategy handling volume risk and apply it to wind farms valuation. Finally, a short review of optimal strategies taking into account transaction costs is made

Analysis of vertical price transmission in the South African potato markets

Mosese, Douglas January 2020 (has links)
Thesis (M.A. Agricultural Management (Agricultural Economics)) -- University of Limpopo -- 2020 / Potato is the most important vegetable crop in South Africa in terms of contribution to the gross value of agricultural production, export earnings and contribution to food supply base and food security in the SACU region. Despite the importance of this commodity, very little is known about the nature of price transmission between different levels of potato value chain in South Africa. The study aims to determine the nature of price transmission in the South African potato market. The objectives of the study are to investigate the existence of long-run equilibrium relationship between producer, wholesale and retail prices; to determine characteristics of the relationship; and to determine the direction of price causality. The study made use of Error Correction Model and Granger Causality test. The Empirical results reveal the existence of price asymmetry in the South African potato value chain. Furthermore, the results show that retail prices are more responsive producer price increases than they are to producer price declines. The Granger causality test shows that prices in potato value chain are determined mainly at the wholesale level (i.e. at the National Fresh Produce Markets). The study recommends further research focusing on price transmission for other basic food commodities and that the government retains and strengthens the existing food price monitoring system. / Department of Agriculture, Forestry and Fisheries

Trust and exchange : the production of trust in illicit online drug markets

Munksgaard, Rasmus 09 1900 (has links)
Au cours de la dernière décennie, les marchés illicites en ligne sont passés de niches de marchés à plateformes économiques à part entière. L’un des aspects de cette expansion semble reposer dans l’abandon de l’articulation traditionnelle de la relation de confiance entre vendeurs et acheteurs pour l’adoption de transactions régies par les principes d’atomisation sociale et d’anonymat. Se situant au cœur d’une sociologie économique des marchés illicites encore émergente, cette thèse cherche donc à étudier l’élaboration de la confiance au sein des marchés de drogues illicites en ligne. En m’appuyant sur la notion d’institutions en tant que constructions sociales, j'avance la thèse selon laquelle ces marchés illicites modernisent les modalités de transaction des marchés licites traditionnels : des contrats sont proposés ; des tribunaux sont érigés; la sanction est formalisée ; et la gouvernance est transformée. Cette approche permet de révéler un schisme fondamental de la littérature et de ses postulats à l’égard de l'ordre social régnant au sein des marchés illicites en ligne -- rupture qui s’exprime notamment par l’opposition entre 1) une conception de ces marchés comme socialement atomisés et régis uniquement par la réputation ; et 2) l’idée selon laquelle les serveurs restent sous le contrôle des administrateurs. Afin de pallier cette discordance, je propose un modèle d’élaboration de la confiance notamment issu des approches cognitives et comportementales. Premièrement, je soutiens qu'un ensemble de mécanismes actifs de renforcement remplace fonctionnellement les principes sociaux traditionnels de la confiance. Deuxièmement, je soutiens que la confiance, aussi bien interpersonnelle qu’abstraite (à savoir, la confiance accordée aux institutions), est principalement produite selon un processus bayésien d'accumulation d'expériences. Dans cette perspective, l'article « Uncertainty and Risk » examine l'ensemble des mécanismes actifs de renforcement de la confiance -- première composante de ce modèle -- et révèle que les vendeurs ajustent les prix non seulement en fonction de la réputation, mais également des contrats et du statut. Dans les articles suivants, le processus bayésien d'accumulation d'expériences -- deuxième partie du modèle -- est abordé. L’étude menée dans l‘article « Building a case for trust » met ainsi en lumière une association entre les échanges répétés avec le vendeur et une tendance à effectuer des transactions de plus en plus importantes. Le troisième article (« A change of expectations? »), quant à lui, met en exergue le fait qu’un faible nombre d’expériences satisfaisantes suffit à augmenter la certitude de l’acheteur quant à la qualité du produit illicite. Dans leur ensemble, ces deux articles soutiennent l’idée selon laquelle le processus d'accumulation d'expériences favorise la coopération et les attentes. Enfin, ce travail s’achève par l’articulation des deux composantes de ce modèle et, de manière plus générale, par l’articulation de la thèse de la modernisation et d’une conception de la confiance dont l’élaboration repose sur un processus d’accumulation d’expériences sociales. L’apport unique d'une sociologie économique dans l’étude criminologique des marchés illicites est notamment souligné et des pistes de recherches futures sont discutées. / During the last decade illicit online drug markets have grown from niche markets into full-fledged platform economies. It seems that over the course of a few years, sellers and buyers have left the social bases of trust behind preferring to exchange under conditions of social atomization and anonymity. Situated in an emerging economic sociological approach to illicit markets, this work examines the production of trust in illicit online drug markets. Drawing on economic sociology, namely, the notion of institutions as social constructions, I advance the thesis that these markets modernize the premodern exchange modes of traditional illicit markets: Contracts are implemented; courts are erected; sanctions are formalized; and governance transforms. This analysis reveals a fundamental schism in the literature and its assumptions about the social order of illicit online markets. Specifically, a conception of these markets as socially atomized and governed only by reputation, versus the recognition that servers remain under the control of administrators. Building off the modernization thesis and the schism, I propose a model for the production of trust that is sensitive to both cognitive and behavioral approaches to trust. First, I propose that a set of active trust producing mechanisms functionally replace the bases of trust that have eroded as illicit markets move online. Second, I argue that trust is primarily produced through a Bayesian process of accumulating experience, which produces both interpersonal and abstract trust. In the article Uncertainty and Risk I examine the first component, the active production of trust. I revisit a key debate in the literature, the pricing of illicit goods. We find that sellers set prices adjust prices not only with respect to reputation, but also contracts and status. In the following two articles, I examine the second part of the model, the bayesian process of experience accumulation. In the article Building a Case for Trust, I find that repeated exchanges with a seller are associated with a propensity towards larger transactions. In the third article, A Change of Expectations?, I find that even a few experiences increases expectations in the performance of the market institution. Thus, the two articles provide evidence that the process of experience accumulation promotes cooperation and expectation. I conclude the work by reconciling a tension between the two components of the model, the proposition that markets are modernized, but that trust is produced primarily through a process of experience accumulation. On this basis, I continue to highlight the contributions and analytical advantages of the economic sociological approach to illicit markets.

Navigating NPD in Unfamiliar Markets : Keys for a Successful Process Execution in Uncertainty / Navigera ny produktutveckling i okända marknader : Nycklar för ett framgångsrikt processutförande i en osäker miljö

Jonsson, Julia, Strand, Hildegunn January 2023 (has links)
Innovation is a crucial activity to ensure companies’ viability and is increasingly important to sustain competitive advantage. Globalization and the accelerating technological development are creating new markets previously not explored. Companies’ capability to execute New Product development (NPD) under these circumstances is limited since this is a new setting for most companies. Literature reveals that developing highly innovative products entails higher potential of economic growth and this incentivizes companies to explore opportunities in unfamiliar markets. It is also previously empirical shown that the NPD process for products targeting unfamiliar respectively familiar markets should differ due to their varying nature. Despite this, companies tend to use the same NPD processes regardless of the market situation which furthermore can hinder companies from succeeding with innovations targeting unfamiliar markets. Considering this, the purpose of this thesis is to explore and identify which aspects within the execution of the NPD process that enable respectively inhibit companies to achieve commercial success in markets of different characteristics. To investigate this, a multiple case study was conducted at a Swedish manufacturer of industrial machines. Two cases representing unfamiliar respectively familiar markets were studied through employee interviews, observations, reading internal documents and informal meetings. The study was conducted with an abductive approach, investigating the empirical reality and existing literature simultaneously. The result of this study reveals aspects that are challenging for companies to contemplate when executing NPD in unfamiliar markets and how it contrasts to the conditions for familiar markets. Raising companies’ awareness of this enables them to be better equipped for executing NPD under unfamiliar market conditions. The main challenges concluded are allocation of human resources and competency utilization, deficient collection of market and customer information, and insufficient communication routines. Moreover, companies fail to evaluate the potential and risk of innovations and have a hard time developing and implementing an NPD process that supports both structure and flexibility in markets with different characteristics. The biggest difference with NPD for unfamiliar market is the level of uncertainty. The challenge of understanding the customer needs and the competitors becomes more tangible for unfamiliar markets, and further places agreat demand on a working communication system, flexibility, cross-functionality, good risk assessment and well-defined product requirements. / Innovation är avgörande för att säkerställa företagens lönsamhet och blir allt viktigare för att upprätthålla konkurrenskraft. Globaliseringen och den accelererande tekniska utvecklingen skapar nya marknader som tidigare inte utforskats. Företagens förmåga att genomföra utveckling av nya produkter (NPD) under dessa omständigheter är begränsade eftersom detta är en ny miljö för de flesta företag. Litteratur visar att utveckling av mycket innovativa produkter skapar större potential för ekonomisk tillväxt och detta uppmuntrar företag att utforska möjligheter i okända marknader. Det är också tidigare empiriskt visat att NPD-processen för produkter som riktar sig mot okända respektive kända marknader bör skilja sig åt på grund av deras varierande karaktär. Trots detta tenderar företag att använda samma NPD-processer oavsett marknadssituation, vilket dessutom kan hindra företag från att lyckas med innovationer som riktar sig mot okända marknader. Med bakgrund i detta är syftet med detta examensarbete att utforska och identifiera vilka aspekter inom genomförandet av NPD-processen som gör det möjligt, respektive hämmar för företag att nå kommersiell framgång på marknader med olika karakteristik. För att undersöka detta genomfördesen fallstudie hos en svensk tillverkare av industrimaskiner. Två fall som representerade okänd respektive känd marknad studerades genom intervjuer, observationer, läsning av interna dokument och informella möten. Studien genomfördes med ett abduktivt tillvägagångssätt, som undersökte den empiriska verkligheten och befintlig litteratur samtidigt. Resultatet av denna studie identifierar aspekter som är utmanande för företag när de utför NPD i okända marknader och hur detta kontrasterar mot förhållandena i kända marknader. Genom att öka företags medvetenhet om detta kan de bli bättre rustade för att utföra NPD under olika marknadsförhållanden. De främsta utmaningarna som har identifierats är allokering av personalresurser och kompetensutnyttjande, bristfällig insamling av marknads- och kundinformation samt otillräckliga kommunikationsrutiner. Dessutom misslyckas ofta företag med att utvärdera innovationers potential och risk, och har svårt att utveckla och implementera en NPD-process som stödjer både struktur och flexibilitet i marknader med olika egenskaper. Den största skillnaden med NPD i okända marknader är nivån av osäkerhet. Utmaningen att förstå kundernas behov och konkurrenterna blir mer påtaglig i okända marknader och ställer vidare stora krav på ett fungerande kommunikationssystem, flexibilitet, tvärfunktionalitet, riskbedömning och väldefinierade produktkrav.

Price Discovery In The U.S. Bond Market Trading Strategies And The Cost Of Liquidity

Shao, Haimei 01 January 2011 (has links)
The world bond market is nearly twice as large as the equity market. The goal of this dissertation is to study the dynamics of bond price. Among the liquidity risk, interest rate risk and default risk, this dissertation will focus on the liquidity risk and trading strategy. Under the mathematical frame of stochastic control, we model price setting in U.S. bond markets where dealers have multiple instruments to smooth inventory imbalances. The difficulty in obtaining the optimal trading strategy is that the optimal strategy and value function depend on each other, and the corresponding HJB equation is nonlinear. To solve this problem, we derived an approximate optimal explicit trading strategy. The result shows that this trading strategy is better than the benchmark central symmetric trading strategy.

Network effects, economic efficiency, and usage-based pricing for internet access

Cooper, Matthew L. January 1900 (has links)
Master of Arts / Department of Economics / Tracy M. Turner / This paper attempts to shed some light on the issue of net neutrality by examining the extent to which Internet usage is efficiently allocated under current conditions. I discuss the unique features of Internet usage which make it a good that markets will tend to provide at an inefficient level. I then discuss alternative pricing regimes that will move the market for Internet usage to efficiency. I conclude with a discussion of the current economic research on the topic.
