Variabilité du taux de change réel, intégration financière internationale et croissance économique : une application aux économies émergentes by Thouraya Hadj Amor( Book )

2 editions published in 2013 in French and held by 3 WorldCat member libraries worldwide

Two major facts hold place to explain the interest of the variability of Real exchange rate (RER) in emergent countries. First, the International Financial integration (IFI), corollary of the abandonment of Bretton-Woods's system, and the proliferation of floating exchange rate regimes, amplified partially fluctuations and disequilibria of RER, notably in emergent countries. Then, the frequent exchange rate fluctuations, called volatility of RER, and the recurrent distortion, called misalignment of RER, build generally a matrix of crises and lower economic performance.These considerations drove economists to reconsider the question of the variability of RER, its determinants and its induced effects on the economic growth in emergent countries. Also, this question occupies a crucial position in research articulating macroeconomic and international finance. Our thesis appears in such a perspective of research; it is a reflection on the characterization of the nature and the extent of the mediation between RER variability and economic growth in the context of International Financial Integration The empirical validation of such a characterization took support on a widened sample constituted of heterogeneous emergent countries, on the one hand, and on an intensive recourse to econometric tools, on the other one. In addition, it has been question of empiric estimation articulating relatively recent econometric techniques, as the GMM in dynamic panel, panel co-integration and the method of Dynamics of Least Squared (DOLS). To the term of this empirical effort, we are allowed to note that the RER variability is an explanatory element of the economic decrease in emergent countries, decrease amplified by the IFI that intensifies this variability
L'impact de la spécialisation sur la stabilité économique : le cas des pays émergents. by Ons Abbes( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

La croissance rapide du commerce mondial au cours des deux dernières décennies a été caractérisée par une évolution économique accrue couplée à de l'instabilité économique des pays émergents. D'après la littérature, la spécialisation technologique est souvent associée à la croissance, la compétitivité et la stabilité économique. Partant de ce double constat, nous analysons dans cette thèse l'impact de la spécialisation des pays émergents sur leur croissance et leur stabilité économique et nous évaluons l'impact de la compétitivité (elle-même liée à la spécialisation) de ces pays sur leurs performances à l'exportation.Dans un premier chapitre, nous délimitons le contour définitionnel des notions de spécialisation selon les différentes théories.Après avoir déterminé le plus objectivement possible une liste de pays émergents en se référant aux critères les plus utilisés dans la littérature et après avoir mesuré le degré de spécialisation de ces pays, nous étudions la carte de leur spécialisation technologique sur la période 1995-2014. D'après cette cartographie, nous remarquons une mauvaise orientation de la spécialisation dans ces pays. Ces derniers se caractérisent essentiellement par une forte spécialisation dans les articles manufacturés à forte intensité de main-d'œuvre et provenant de ressources naturelles et dans les articles à faible technologie qui sont des spécialisations à faible valeur ajoutée. La spécialisation dans la haute technologie est en grande partie tirée par les importations, les produits exportés étant principalement issus d'activités de montage.Dans le duexième chapitre, nous évaluons dans un premier temps l'impact des spécialisations technologiques des pays émergents sur la croissance économique et nous comparons les résultats trouvés à ceux des pays développés et en développement. Nous constatons que les différents types de spécialisation ont un impact positif sur la croissance des pays émergents. Mais cet impact positif, ne peut pas occulter la mauvaise orientation de cette spécialisation (résultat du chapitre 1).Dans un deuxième temps, nous étudions l'impact de la compétitivité (prix et hors-prix) des pays émergents sur l'évolution de leurs exportations. Nous remarquons que l'impact de la compétitivité-prix sur l'évolution des exportations des pays de notre échantillon varie selon l'indicateur utilisé. Il est négatif quand nous utilisons le taux de change et positif quand nous utilisons la productivité.Nous trouvons aussi que l'impact de la compétitivité structurelle, expliquée par les dépenses dans la haute technologie et par la spécialisation dans la haute technologie, est positif. Cela peut être expliqué par la demande mondiale croissante dans les produits de haute technologie.Dans le troisième et dernier chapitre, nous nous intéressons à la relation entre spécialisation et stabilité économique et nous comparerons cette relation avec celle observée dans les pays développés. Nous constatons que les pays dont la spécialisation est basée sur les ressources naturelles sont plus instables et que l'impact de la spécialisation dans la haute technologie dépend du niveau de développement du pays. L'impact est négatif pour les pays développés et positif pour les pays émergents. Cette différence dans l'impact peut être due à la politique d'assemblage utilisée par la plupart des pays émergents, politique qui consiste à importer la majeure partie des produits de haute technologie (HT) sous forme de pièces et composants
Les mutations induites par la libéralisation commerciale sur la restructuration compétitive du système productif tunisien by Amel Aloui( Book )

2 editions published in 2014 in French and held by 2 WorldCat member libraries worldwide

Within an international context, deeply marked by the globalization of markets, the acceleration of geopolitical, economic and environmental transformations, the external opening have imposed significant transformational effects on the whole production sectors. The latter have to confront with a growing interdependence between the Nations which impose to actively develop their international relations through movements of integration, opening and the liberalization of their markets. After placing the doctrinal foundations of the mutations theories and the economic theories of development as a response to the changes induced by this new context of international opening, this work approaches more specifically the topic of statute of the international trade; on the one hand according to the economic logic, and on the other hand according to the nature of its impact; taking the Tunisian economy as an illustrative example. Within such a frame, the study of the commercial tendancies evolution and of the sectorial implications of the commercial liberalization in the Tunisian case is of great importance. Our first investigation about the empirical evaluation of the sectorial impact of the international trade on the restructuring of the production system has brought out mitigated results; yet, confirm to the socio-economic specifications of Tunisia on the international scale. For this purpose we were induced to determine the repositioning of the industrial sector in the productive sphere on the interior level and to specify the hierarchisation of this economy in terms of competitiveness, with reference to a set of Mediterranean developed countries. Our second investigation, through the estimate of competitiveness exportation index of the OECD attributes Tunisia a position relatively better than that of certain European developed countries. This strategic positioning at the interface of many European countries grants it an essential role in the Euro-Mediterranean cooperation within an internationalization context; this classification must be relativised by the socio-economic costs
Etude évaluative des effets induits des opérations de fusions-acquisitions opérées en Tunisie by Rania Ferchichi( )

2 editions published in 2012 in French and held by 2 WorldCat member libraries worldwide

This thesis provides a detailed analysis of M&A in Tunisia by identifying their motivations and assessing their impact on firms. In a first step, the research is to develop an M&A database on the period 1980 to 2009. Statistics shows that M&A has accelerated since 1995. They are more common in the industry and occur mainly in Grand Tunis and coastal regions. They are mostly horizontal and realized between firms in the same sector. Finally, they are a means for large firms to grow by acquiring SMEs. The second step was to conduct a survey of managers of the database about M&A motivations and performance. The results show that the main motivations for M&A are economies of scope and synergies, improving the profitability of the new combined entities and tax savings. Finally, the evaluation of M&A transactions performance is based on two approaches : the economic and accounting ratio approach and the financial approach, using event studies. It turns out that the M&A have no significant effect on economic and accounting firms' performance. However, the financial approach shows significant decreases in cumulative abnormal returns for the entire sample, for acquiring firms and targets
L'économie politique de la globalisation financière : application au cas de la Tunisie by Azza Ziadi( Book )

2 editions published between 2012 and 2014 in French and held by 2 WorldCat member libraries worldwide

This research has thus worked to confront the lessons of international political economy to the test of reality Tunisia. It has set itself the objective to outline, from the Tunisian experience, financial and real effects of financial globalization on the Tunisian economy. The political economy of financial globalization based on an analysis of the interrelationships between market dynamics and those of public and private economic agents that have developed from the late 1970s. Such analysis would allow to trace the main features of financial globalization on contemporary and reflects a political reflection on the new referents of the state and the trajectory of its transformations. Thus, we witnessed the withdrawal of the state facing the global economy and finance ? What are the profound asymmetries in power relations and the domination of finance ? We will focus in particular on the transformations of public and private financial institutions in Tunisia during the last three decades, and their new joint fiancial system of Tunisia ? We analyze the different regulatory policies that had orchestrated interactions between public and private sectors on the one hand and domestic capital and foreign capital on the other. It is in this perspective that is our problem : it is a study of transformations of the state in the era of globalization, and, by reference to the experience of post-colonial Tunisia

Structure, stratégies et efficience bancaire : le cas des banques commerciales tunisiennes by Lamia Daly( Book )

in French and held by 1 WorldCat member library worldwide

This thesis joins in a prospect of not motionless characterization of the mediation between the structure, the strategies and the risks and the efficiencies of the Tunisian banking system. In a first chapter, the characterization of the structure of the Tunisian banking system is shown that a monopolistic competition is imperative due to barriers in the entrance connected to the presence of the only approval. In every shape of control would correspond a strategy, the Tunisian bank has to opt for the good strategic choice what is the object of the second chapter. The chapter three put in evidence the various types(chaps) of risk inherent to the activity of credit institutions, the developments mentioned in this chapter reveal the multiplicity of these risks and their multidimensional character. The last chapter aims at determining the scores of efficiency as well as the study of the impact of certain variables on these last ones, within the Tunisian banking system. Il proves a decline of the scores of the aforementioned efficiency due to the results of the banking reforms introduced in 1987 which had no effect on the efficiency of the Tunisian commercial banks
Intégration financière, gestion alternative et diversification de portefeuilles by Wafa Kammoun Masmoudi( Book )

2 editions published between 2012 and 2014 in French and held by 1 WorldCat member library worldwide

This thesis is interested in studying the new landscape of financial markets in which hedge funds have taken an important place that may affect financial stability and particularly portfolio diversification benefits. During the last two decades, financial globalization has allowed interaction of international markets and an extension of the principle of risk diversification in several markets. This has resulted in increased volatility of funding sources and increased financial instability amplifying financial market trends. International financial integration is one of the major trends of the contemporary movement of globalization of economies. Its apprehension is useful for investors whose portfolio investment strategies are closely related to the degree of integration of financial markets. However, due to the rise of the interdependence of financial markets, reducing a priori the potential gains from diversification, new alternative investments offer new opportunities for investors. This research explores the dynamic relationship between the returns of domestic equity and bond markets for developed and emerging countries in order to approximate time variations in inter-stock-bond market integration and to identify the main economic and financial determinants. The analysis of financial integration leads us to question the structure of investors in the world. We note that the predominant development is the advent of the hedge fund industry. Thus, this thesis proposes to expose the basics of alternative investment and to explore empirically how the systematic risk exposures of hedge funds vary over time conditional on some exogenous variables that managers are assumed to use in changing their trading strategies. Given the dynamic structure of risk exposure of hedge funds, the thesis attempts to study the dynamic links between the global macro strategy and traditional financial assets. The results show on the one hand, that there is a significant time-varying conditional correlation between stock and bond indices over the sample period. In times of financial turmoil, the DCC down and even become negative for developed countries, confirming the phenomenon of flight to quality in the international financial markets. This variability is mainly due to the exchange rate volatility and economic uncertainty in the financial system. In the other hand, we have shown that (1) volatility, term spread and shocks in liquidity significantly impact on the time variation of hedge fund betas; (2) beta dynamics show that leverage levels and shocks in liquidity are the key factors underlying the dynamics of systematic risk. Finally, our results demonstrates the destabilizing forces of global macro especially on emerging markets and the existence of the short- and long-term relationships between global macro and financial assets for Canada, France and Germany, providing less diversification benefits
Le rôle de la supervision des banques islamistes, approche islamo-juridique by Aasem Madkhali( )

1 edition published in 2016 in French and held by 1 WorldCat member library worldwide

The present study covers the issue of islamic financial institutions in overall, with a particular attention attributed for islamic banks. The topic is interesting because of the direct relationship with the compliance monitoring with the Shariaa, regulatory and legal of Islamic banks. These financial institutions and Islamic banks offer various products of financing and develop several conventional products adapting them to the principles of Islamic finance, including the absence of usury (interdiction of riba). We should mention that some financial institutions and Islamic banks begin to divert for their advantages the principles and the basic rules that justified the existence of Islamic finance, like substitute for the traditional bank. And the role of institutions of compliance monitoring is limited to provide advises without intervention to prepare the failures, in other terms their decisions and recommendations did not have the binding force. These findings allowed deepening our analysis to pose the question regarding assuming the consequences of the civil liabilities under the 2 forms: contractual and delictual, in addition to the consequences and the criminal liabilities for the members of these authorities of compliance monitoring. The role of these organs could be more effective and efficient, like we underlined with the regulatory approach of their activities and the works of these authorities of compliance with the Shariaa. The present dissertation provides a comparison between the Islamic banks activities and the regulatory monitoring from the perspective of the Islamic rules of Shariaa and the regulatory monitoring of the activities of Islamic banks form legal perspective
Responsabilité sociale des entreprises et développement durable dans la vision 2030 de l'Arabie saoudite by Mohammed Almutairi( )

1 edition published in 2021 in French and held by 1 WorldCat member library worldwide

The new welfare state, resulting from the mixed economy, conveys an ideal partnership between the private, the public and the civil society. From this partnership could emerge a corporate social responsibility and a stronger societal commitment of governments. In doing so, it lays the foundations for sustainable development. Companies are thus both pushed to produce more while subscribing to the socioeconomic development programs of the nation and by complying with the social rights of its micro and macro environments. It is in such a perspective of reforms that Vision 2030 constitutes an opportunity for Saudi companies to rise to a higher level of international competitiveness while contributing to the sustainable development of the Kingdom

The public-private partnership contract is defined as an administrative contract by which the State or a public institution of the State entrusts to a third party, for a period determined according to the depreciation period of the investments or financing modalities retained, a global mission for the construction or transformation, maintenance, maintenance, operation or management of works, equipment or immaterial goods necessary for the public service, as well as all or part of their financing except for any shareholding. It may also have as its object all or part of the design of such works, equipment or immaterial goods as well as services that contribute to the exercise by the public corporation of the public service mission for which it is responsible. The concept of public-private partnership is suitable and moreover used for the development of sports equipment. Today, new equipment, in terms of investment and operation, tends to involve private financing. This trend is particularly noticeable for large structuring equipment projects such as large stadiums, for France or for the Arab Gulf countries. Therefore, the public-private partnership contract is a solution to restore the park of sports facilities and equipment. The allocation of the Euro 2016 to France, was the opportunity to accomplish projects of construction and / or renovation, through the form of partnership contract, the stadiums of Lille, Marseille, Nice and Bordeaux
Les conflits sportifs dans les législations française et saoudienne by Ali Somaili( )

1 edition published in 2018 in French and held by 1 WorldCat member library worldwide

La pratique sportive est aujourd'hui soumise à une grande diversité de règles d'origines différentes qui dessinent des ordres juridiques distincts, privés et publics : des ordres juridiques d'État et des ordres juridiques du sport dont les relations prennent fréquemment les traits d'un « pluralisme juridique positif organisé ». En effet, la lex sportiva ou le droit de sport peut être définie comme étant l'ensemble des règles qui régissent les droits et les obligations des sportifs. Il porte notamment sur les règlements sportifs des différentes fédérations sportives, le dopage, les règles de transfert de joueurs. De même ce droit tend à résoudre les différents litiges qui peuvent en en découler. Le litige peut être définie comme étant un différend ou désaccord entre deux parties, physiques ou morales, dont les unes contestent aux autres d'être « titulaires d'un droit à l'exercice duquel elles prétendent ». Le désaccord entre les parties du litige, peut naitre d'un contrat ou d'une situation de fait. Ces parties vont d'abord essayer de résoudre leur différend à l'amiable, à défaut d'accord, le litige sera soumis à un Tribunal qui va le trancher. On rencontre les litiges dans tous les domaines, civil, commercial, administratif, sportif... Ce dernier secteur, à savoir le secteur du Sport ou plus précisément les conflits en matière de sport, qui sont de diverses natures et dont le règlement exige le recours à des instances spécialisées en la matière et l'application des textes propres à ce type de litiges, constitue le principal objet de recherche de ce travail. Les différends en matière de Sport, peuvent se résoudre devant les tribunaux de droit commun. Mais, l'inadaptation de ces derniers à des litiges nécessitant des compétences « techniques particulières qui doivent compte tenu de la brièveté d'une carrière, être réglés rapidement, a entraîné le recours - de plus en plus fréquent - aux modes alternatifs de règlement des conflits ». Contrairement aux autres litiges, qui ont une situation contrastée, la situation des litiges sportifs est claire, transparente, et originale. Pour cela, et pour répondre à leurs besoins spécifiques, les organismes sportifs, ont créé et développé des règles législatives propres qui assurent leur fonctionnement, et ont constitué des instances qui assurent la bonne application des règles qu'elles ont édictées. Les conflits Sportifs sont donc réglés par des règlements et des statuts particuliers et spécialisés en matière du sport, qui permettent aux parties à un litige d'aboutir à des solutions pratiques et satisfaisantes. On peut dire que la régularisation de l'activité sportive peut se faire de manière autonome et échapper aux pouvoirs publics, à l'ordre étatique. Les Règlements Sportifs sont donc, des Règlements autonomes et suprêmes vis-à-vis des législations de l'Etat. En effet, la création de ces règlements spécifiques, a entrainé la création des instances juridictionnelles spécialisées compétentes à régler les conflits des organismes sportifs, et qui fonctionnent conformément à leur pouvoir réglementaire. En examinant les règlements d'Arbitrage qui gouvernent les organismes sportifs, on peut se rendre compte qu'ils comprennent des dispositions spécifiques déterminant la compétence des Instances Arbitrales par rapport à la notion de Sport. Avec la croissance et la prospérité des échanges commerciaux à l'échelle internationale, l'Arbitrage s'est révélé être le recours préféré en matière de transaction internationale. De là, et devant l'internationalisation et la complexité des litiges, les législations et les jurisprudences internes des Etats, ont reconnu et consacré la pratique de l'Arbitrage
L'importance du marché obligataire dans le financement de l'économie : essai sur les modalités de développement des marchés obligataires émergents avec référence au cas tunisien by Jamel Boukhatem( )

1 edition published in 2010 in French and held by 1 WorldCat member library worldwide

L'objet de cette thèse consiste à mener une réflexion approfondie sur deux éléments majeurs de l'économie financière, en l'occurrence, l'apport d'un marché obligataire dans l'optimisation de la structure de financement aussi bien sur le plan microéconomique que macroéconomique et les politiques susceptibles de concourir à son développement. La finalité de notre recherche est de contribuer à une meilleure compréhension de l'importance des marchés obligataires dans les économies notamment émergentes et des politiques à mettre en œuvre pour les développer.Des marchés obligataires locaux opérationnels apparaissent clairement comme sources d'opportunités pour les investisseurs par les divers gains d'efficacité qu'ils procurent. Ils contribuent ainsi à l'amélioration de l'efficacité économique du pays, et ce, en imposant une « discipline de marché » à l'économie dans son ensemble.S'agissant des modalités favorisant le développement des marchés obligataires, nous avons bien démontré qu'une combinaison de politiques économiques semble assurer leur prospérité et, partant, leur décollage. Dans ce sens, des systèmes bancaires plus compétitifs et plus efficients, des politiques macroéconomiques saines (des taux de change moins volatils et une politique fiscale appropriée), une infrastructure de marché robuste et un cadre juridique transparent et solide (des institutions plus fortes) sont au centre d'une participation élargie des investisseurs nationaux et étrangers aux marchés obligataires à moyen et long termes augmentant, par delà, la diversification internationale de capitaux. Cette thèse cherche donc à concilier les études techniques spécifiques au sujet de la structure, voire de la microstructure des marchés de valeurs et les écrits offrant des recommandations de politique générale au sujet de développement desdits marchés. Elle intègre ces deux perspectives en décrivant les questions importantes confrontant les responsables politico-stratégiques ou ceux mettant en application des politiques économiques pour appuyer le développement des marchés obligataires
