Full textThe concept of relevant market, its content and use illustrate the incorporation by the law of economic methodologies and tools traditionnaly used by economists. Very well known from lawyers specialized in antitrust law, the concept of relevant market has recently been incorporated in the rules concerning the regulation of the electronic communications sector (ex ante regulation). This incorporation is the fact of the European commission through the regulatory frameworks of 1998 and 2002. These statutes aim at the deepenning of the internal market and an effective competition in the communications sector, achieving in this way the liberazation process started 20 years ago. The two branches (ot two means) of the liberalization policy are communications law (ex ante regulation) and antitrust law (ex post regulation), the former being deemed to be replaced by the latter, once the aformentionned objectives being achieved

Full textThe law has produced a specific kind of market with the help of two instruments : first, naturalist references to the liberal market ; second, the model of efficiency and competition. When an activity is regarded as "economic", there is a distinct leaning toward a certain kind of regulation, that of competition - otherwise known as "the market rules". Its is a matter of re-qualifying actions which may be described as economic by the sheer fact that they may "trigger or produce effects" on the market. The notion of economic activity blurs the borders between realities and, indeed, disciplines. The market category, as constructed by the law, has effects over the entire legal system. It produces discorders as well as certain and necessary re-organisations, for the law constantly needs to re-establish its coherence and unity. The expansion of competitive market to traditionally excluded areas raises the problem of the partition of this very category. Whereas the existence of the market may not be called into question whenever the validity of the rules of competition is verified, it may be disputed outside the realm of competitive market. Therefore, there is a need to delineate this progression of the competitive market model and to properly define the existence of an original market

Full textL'Orientation-Marché est généralement définie comme étant l'implémentation du marketing dans les organisations. Une revue de littérature permet de l’opérationnaliser par les dimensions telles que l'Orientation clients qui consiste en la poursuite de satisfaction des clients, Orientation concurrents, Coordination inter/intra fonctionnelle, et la Réponse organisationnelle. Cette stratégie est de plus en plus évoquée comme pouvant aider les institutions d'enseignement supérieur à faire face aux défis tels que la massification, la professionnalisation, la réduction des financements, la montée des exigences des parties prenantes en termes de qualité. Dans cette thèse, je constate d'une part que certains chercheurs se limitent à proposer cette stratégie sans en définir le contenu, et d'autre part que les travaux empiriques existants sur l'Orientation-Marché dans l'enseignement supérieur se limitent à des transpositions conceptuelles, sans tenir compte des spécificités des institutions d'enseignement supérieur. C'est pour cette raison qu'après avoir démontré l'origine des discours sur l'Orientation-marché dans ce secteur, je développe une échelle de mesure susceptible d'Opérationnaliser cette stratégie. L'échelle comprend l'Orientation vers les parties prenantes (Etudiants, Décideurs politiques, Entreprises), l'Orientation Concurrents, la Collaboration, la Coordination Interfonctionnelle, et la Réponse organisationnelle comme principales dimensions. La validation empirique de ces dimensions a été enrichie par une évaluation quantitative de la place de l'Orientation-Marché dans les missions des institutions d'enseignement supérieur, telles que déclarées dans leurs différents documents. Cette recherche est une première ébauche dans tout un courant de recherches sur l'importations des stratégies de gestion privée dans les institutions à but non lucratif.

Mitsiopoulou, Sofia. "Le marché des infrastructures de transport : les aéroports et les ports." Thesis, Paris 1, 2014. http://www.theses.fr/2014PA010312.
Full textThe liberalization of air and maritime transport has resulted in the transformation of the respective infrastructures, in order to facilitate competition between transport operators. However, the most remarkable change has been the development of competition between them. In spite of the particular tasks of general interest assigned to the infrastructures of transport and although each infrastructure taken separately holds a considerable market power, airports and ports are susceptible to competitive pressure. Indeed, the natural monopoly characteristics have been relativized due to the mobility in the economy of transport. Both airports and ports often become simple links in the competitive strategies of carriers, which constitute their powerful counterparts. The law responded to this economic phenomenon, by dismantling state monopolies, proceeding to their privatization or decentralization. Therefore, this tendency has led to a competition between emerged operators, for and within the "market of infrastructures". This market is certainly "hetero-determined", which means that it is highly dependent of the competition in the market of transport. Thus, the definition of the relevant market takes into account the market of transport. Besides, the possible forms of competition or cooperation between infrastructures are determined by the carrier strategies

Full textDue to the health hazards relative to the use of medicine, French, Swiss and British public authorities took the choice to intervene in the pharmaceutical industry. Medication, partly put aside from the market, then became an object of public matter requiring a specific legal framing. Incorporated into the health system, it is the preferred target of public health insurance cost-containment policies. Prices are not bound to the mechanism of supply and demand. Production, elaboration and distribution are liable to specific deontological constraints. Though medicines are a matter of public health, they are nonetheless an industrial good. Integrated to the market, they are at the core of the rivalry between pharmaceutical companies, who seek economic efficiency. With the aim of creating a favourable environment for the economic development of the segment, it is essential to keep the market going smoothly, by forbidding anticompetitive practices and fighting restrictive competing practices. The support of self-medication, tax incentives for research and the protection of pharmaceutical innovation are incentive factors of an optimal pharmaceutical production. Moreover, pharmaceutical companies display important competitive skills, through research and development, promotional policies, commercial cooperative agreements and, restructuring policies. Facing a prominent criterion of economic efficiency, will public service be able to survive ?

Full textMarket definition is one of the most important analytical tools used by the competition authorities to examine and evaluate competition problems. But it is also the most difficult subject of competition law and has been the subject of heated debate between lawyers and economists for decades. The issue has never been resolved once and for all. Indeed, since the beginning of this decade, Professor Louis Kaplow, the most recent “hostile proponent” to market definition, has questioned this procedure while arguing that it should be abandoned. At the same time, the American economists Carl Shapiro and Joseph Farrell propose an economic method named Upward Pricing Pressure as an alternative to market definition in analyzing the competitive effects of mergers in markets with differentiated products. Several derived tests following the same principle were developed. The current debate seems to have taken on a more fundamental dimension, in particular since 2010 when the US competition authorities revised the Horizontal Merger Guidelines which state that market definition is not necessarily the first step in a merger analysis. These important developments raise the question how European competition law should react. Should market definition remain a prerequisite for any competition analysis or should it be replaced by other quantitative methods? While the relevant market plays a role as an instrument of analysis in all areas of European competition law (cartel, abuse of dominant position and merger control), what would be the legal consequences of abandoning it altogether? From another perspective, could the exclusion of new economic methods have any repercussions incases, such as in certain specific markets, where the definition of the relevant market using the hypothetical monopolist test (TMH) would not be the best way to assess anticompetitive effects? Is market definition based only on demand-side substitutability, in the current practice of the European Commission, an appropriate approach? In the context where the concept of relevant market is now commonly used in almost all countries where competition law exists, the impact that the evolution of European law, being one of the most advanced in the world, can have on others should not be underestimated. Vietnamese competition law would certainly be impacted as it is based on the principles of European law and its administrative model

Full textThis PhD thesis set the milestones that are relevant for the competitive analysis of markets based on network activities and digital products or services. This work counts three parts, designed as separate essays, and aims to appreciate the impact of the characteristics of these markets on their competitive dynamics. The first part of the thesis tackles the concentration issue of online platforms. We specify a model of two-sided market in order to appreciate the different levels of interdependence on online platforms linking on firms (or advertisers) on one side and audience or consumers on the other side. As a result, network effects (synergies and scale economies relating to the number of users) are such that any competitive advantage (first-mover advantage, better quality or market share…), as low as it can be, turns out to be durable. The second part deals with the “relevant market” delineation in horizontal mergers issue and suggest an application to the retail market for fixed broadband Internet access. We econometrically analyze the demand for broadband access in order to verify whether or not there exists a segmentation (or even a differentiation) of the demand depending on the access technologies that can be very fast broadband or regular broadband access technologies. The third part examines the effects of “ad-blocking” software on the media and content providers whose business model is based on free access. We also specify a model of two-sided market in order to appreciate the role that Internet service providers can play to internalize network effects and to curb congestion phenomena

Full textThe definition of the relevant market aims at identifying the competitive constraints that an undertaking faces and, thus, defines the scope of competition law enforcement. Given the antagonisms that characterise the pharmaceutical sector, defining the relevant market in this industry seems to disqualify the classic methodology and points out the tensions between law and economy. The interaction of an irrational demand - one which is insensitive to the expenditures and that doesn't define its needs on its own - with an offer naturally monopolistic, makes the involvement of the State in the market mechanisms strictly necessary to ensure its equilibrium. This thesis demonstrates how the conventional tools used to define relevant product markets remain operational inspite of the idiosyncrasies of the pharmaceutical sector

Full textCharles Brook Dupont-White (1807-1878) is a French economist and philosopher who, in opposition to the majority of the economists of his time, is favourable to state's intervention. He considers that market economy without State -which he calls "free production economy" - is a regime which brings about progress and enrichment, but which is a factor of crises, incertitude and increase in misery for a part of the population. The target of this thesis is to lay the emphasis on the novel and precursory aspect of Dupont-White's work, in demonstrating that, as early as the beginning of the nineteenth century, this author had put forward the modern theory's basis of state's intervention to correct the effects of market economy's failings, and particularly to answer the social issue. At a time when the economists where opposed either to state's intervention or to market economy, Dupont-White recommends state's intervention into a market economy. He is the first to lay the basis of what was called, at the end of the nineteenth century, the state's socialism, doctrine which was later theorised by German historic school. Much before Wagner, he formulated the law of public activities' extension and we find in his work the functions of the State that were to be defined much later by Musgrave. Finally we will see that Dupont-White is not awarded the rank he should have deserved in the history of economic thought; he is a heterodox economist whose theses are close to those of social-democracy

Full textCompetition is associated to the well being of the whole community. That myth is very important in the mind of interprets responsible of implementing competition law. However the reality of the business world is very far from that myth: monopoly, oligopoly, monopsony, are usual market environment that the judge and competition authorities have to deal with. The imperfect reality of competition needs such a myth in order to be a political and social institution. The idea of a competition useful to public interest is necessary to justify a reality much more complex. Competition law allow us to believe that free competition triggers a lot of benefits, but also gives arguments to the economic actors in order to develop their competition strategies. Therefore, we can assess that the economic concepts used in competition law are not concepts of economic analysis. The economic vocabulary is transformed in legal categories and proving means. Indeed, if competition was as perfect and pure as the myth says, legal rhetoric wouldn’t be necessary to justify the behaviors of competitors on the market. . The frame of evaluation of the unlawful undertaking depends of the legal rhetoric. Therefore, each school of legal rhetoric gives its ones evaluation standards. Yet, the terms of the discussion are also on the ethical ground

Full textIn the ideology of economic liberalism, the government assumes the role as regulator to ensure compliance with market rules and regulation. Indeed, these rules and regulations control two sets of relation. One applied between economic entities is competition rules justified by the equal opportunity principle. Other applied between business operator and consumer is consumer protection regulations justified by the subordinate position of the consumer towards the operator in commercial practices. Although, these two fields of law don’t have the same scope of application, they pursue a common objective to encourage a fair access to products and services in terms of price and quality. This objective cannot be archived without installation of competent authorities. At this point, difference in nature of these authorities between two areas of law shall be analyzed by an institutional approach. In addition, a comparative approach will be used to compare the competition and consumer protection authorities system in France and the system in Thailand in the context of European Union and ASEAN Economic Community

Full textIn recent years there has been a significant increase in the transfer of corporation control in the business world. Transfer of control, which has the purpose of changing decision-making power within the company, is not only a procedure of company transfer, but it’s also a merger procedure. This identification of the nature of Transfer of control raises several legal issues in our comparative study of French and Syrian law. Indeed, insofar as it is a personal decision of the shareholder or partnership to relinquish control over the company for the benefit of another person, this leads us to determine the legal mechanism of such contracts, by highlighting those questions concerning the formation of the contract, and means of protecting the parties from its effects. As the transfer of control is a personal decision, it is important to identify the problems of protection of third parties from this decision (minority shareholders and employees) because they have no power to prevent such decisions from being taken. Similarly, the change in decision-making in a company can impact negatively on competition, notably through the creation of mergers or a dominant market position. The risk represented for the market by this type of transaction leads us to identify the mechanisms and means which have been put in place by the French and Syrian authorities, such as a prior and subsequent supervision of this transfer of control

Full textOur research focuses more specifically on the selection criteria to be used to improve the relevance of the multiple-Based valuation method regarding the selection of reference multiples, the selection of comparable companies or the combination of multiples.We confirm that the Enterprise Value multiples based on prospective Ebit and Ebitda (versus actual) are generally the most relevant. In the absence of prospective data, available at the date of valuation, our study shows that Ebitda multiples are generally more relevant.We confirm that the expected growth rates of Ebitda or Ebit are generally relevant performance indicators to identify the most comparable companies among industry-Based peer groups, considering actual Ebitda and Ebit-Based multiples.Our study shows that the combination of Capital employed and Ebit-Based multiples, on the one hand, and of Ebitda and Ebit-Based multiples, on the other hand (based on weighted factors specific to each sector), are likely to improve the relevance of the method, compared to the use of these multiples, alone.The approach implemented in this research may be reproduced by practitioners to identify case by case single and combined multiples that are the most relevant for each industry-Based peer group

Full textLegal thinking about business opportunities is traditionally confined to the field that has emerged: the law of fiduciary relationships. In this context, a business opportunity is traditionally viewed as a chance captured by the social leader. But is it not desirable to give the notion of business opportunity a broader dimension? A business opportunity is indeed an opportunity to engage in an operation or activity. As an economic opportunity, a business opportunity emerges on the market. On what condition, however, can an opportunity to contract be considered opportune by the person who is about to seize it? Is every opportunity, moreover, freely seizable? What is, in other words, the legal treatment of business opportunities? Identifying a business opportunity is to determine whether or not an operation or activity is appropriate for the person who is called upon to seize it. In any case, the law controls the means of identifying a business opportunity, the identification of a business opportunity should not be an opportunity for all excesses. The legal treatment of business opportunities is twofold. At the end of its traditional interdiction function, the law discourages the capture of a business opportunity. But now embracing a perspective complementary to that which is classically his own, the law's mission is to encourage the seizure of business opportunities. The meaning of the study is thus to reveal the apprehension, much wider than it seems, of business opportunities by private law

Full textChanges in the French cut flower market are indicative of developments at the European level, in particular the consolidation of traditionally fragmented retail. Supermarkets along with florists franchises are leading this consolidation which has seen the reorganization of the entire supply chain. This analysis of the French cut flower market begins with a study of new modes of governance arising from retail reorganization. It then continues with a thorough study of the impacts of this new governance on actors at the upstream of the GVC (Global Value Chain). The methodology focuses on multiple case studies based on different GVC actors in France, Holland and Brazil. A major consequence of GVC restructuring is the strengthening of links between retailers, importers and foreign producers. While the retailers eliminated some intermediaries such as Dutch auctions and wholesalers, the importers increased their role by upsizing among them. The takeover of the GVC by retailers heavily impacts on producers in terms of volume, innovation, competitive pricing and quality standards. It mainly results in downstream integration of production which brings out PO (Producer Organizations) and excluded a part of unorganized small producers from the market. The case of Brazil confirms that the organization of the production sector is the essential condition of its access to a market driven by European retailers

Full textWaste was previously apprehended along the classic summa division of public and private law while concealing its environmental dimension. This traditional distinction has been called into question ever since the notion of waste has gradually expanded in view of economic and environmental issues. The unity of the notion of waste around his inherent parts is now necessary. The ambivalent nature of waste dictates us to go further than this division of law. In order to respect waste’s integrity and its true nature, environmental law must work together with other branches of law towards a co-production that implies mutual constraints. Defining the different ways these legal disciplines collaborate constitutes the study’s objective. These are founded on one hand, on waste management’s integration into market laws, ensuring the meeting of environmental and economical considerations and on the other hand, on the application of competition law to waste management when practices integrate an environmental aspect. Only once the interactions between environmental and economical imperatives are defined can waste’s unity be recognised

The data for this research was collected from October 2010 toJanuary 2011 in Iranian pharmaceutical industry. Sample size is 500 new product projects.XIThe respondents should have experience on launching at least five or more new product sinceJanuary 2007 in order to be qualified to answer this study. We asked marketing managers toselect new product projects introduced after January 2007 by their firms, defined by the firmsas a clear commercial and answer this survey based on the case of that product introduction.Thus, several decisions managers make in the new product launch require choosing launchdecision options consistent with already made launch choices. From the data, we also identifythree generic launch strategies across which new product success statistically varies. Althoughthe set of decisions, which comprises each strategy, is only a smaller portion of the full setinvestigated, we find that these decision sets are associated with different levels of success.We also study effects of competitive reactions on launch strategy structure and new productsuccess

Full textThis thesis constructs a theoretical model that renews the traditional approach of the market equilibrium. By introducing into the neoclassical paradigm the principle of preference for quantity, it optimally generates inventories within a competitive market. The results are very important since they explain both the emergence of unsold goods and the existence of economic cycles. In addition, it studies the optimal behavior of a monopolist whose the market power depends not only on the quantity of displayed goods but also that of goods that the main consumer is willing to buy. Contrary to the traditional assumption that the monopolist chooses price or quantity that maximizes its profit, through a generalized Lerner index (GLI) it attracts customers’ demand by both the price and the quantity of displayed goods. Whatever the market structure, the phenomenon of inventory accumulation appears in the economy. Furthermore, it has the advantage of explicitly explaining impulse purchases untreated by economics. To check the robustness of the results,the theoretical model is fitted to U.S. data. Due to its nonlinearity, the Gauss-Newtonmethod is appropriate to highlight the impact of consumers’ preference for quantity on production and accumulation of goods and consequently GDP forecast. Finally, this thesis builds a two-country overlapping generations (OLG) model which extends the dynamic OLG equilibrium to a frictionless dynamic OLG gamma-equilibrium. Based on the cash-inadvance constraint, it highlights the conditions of over-accumulation of capital and welfare implications of capital mobility in a context of accumulation of stock of unsold goods
