Cette thèse examine l'impact de la transparence informationnelle des banques sur la stabilité financière pendant la période 1990-2013. Elle est composée de deux essais empiriques, un essai théorique, ainsi que d'une revue de la littérature. Le premier chapitre met en lumière la littérature existante, théorique et empirique, qui servira comme tremplin pour le reste de la dissertation, Le chapitre 2 teste les effets de la transparence informationnelle des banques sur les prix des swaps de crédit pendant la crise de la dette souveraine européenne, sut- la période 2010-2013. Les banques les plus transparentes sont les banques qui souffrent le moins de la volatilité des prix des swaps de crédit au moment des annonces de dégradation des notes des états. La transparence, via la gouvernance des marchés financiers participent à améliorer la stabilité financière. Le chapitre 3 teste, théoriquement, les incitations à retirer des déposants en présence d'ambiguïté et dans le cas où l'information est imparfaite. Les résultats montrent que plus leur degré de pessimisme génère une incitation supérieure à retirer leurs dépôts de l'institution dans laquelle ils ont déposés. La combinaison de l'ambiguïté et de l'asymétrie d'information ouvre la porte à de nouvelles perspectives en termes de transparence informationnelle de la part des banques en direction des déposants et participant ainsi à l'amélioration de la stabilité financière en évitant les paniques bancaires. Le chapitre 4 teste empiriquement les résultats obtenus dans le chapitre précédent. Nous testons l'attractivité, pour les déposants, des banques les plus transparentes sur la période 1990-2013 tout en prenant en considération l'ambiguïté. Les résultats confirment que l' ambiguïté a un effet négatif sur le montant des dépôts totaux des banques et que la transparence informationnelle peut activer des incitations au retrait chez les déposants. / This thesis tries to understand the relationship between banking disclosure and financial stability for several actors of bank's governance. Disclosure has a positive impact on financial market participant made possible by a reduction of the information premium. Regarding depositors, we decided to partially reject the hypothesis of perfect rationality by introducing the ambiguity notion. We were able to show that a negative relationship exists between ambiguity and deposit levels bath theoretically and empirically. Disclosure policies have therefore a negative impact on European total deposit empirically.

This study provides an empirical analysis of Shadow banking as a factor influencing cross- border financial flows. It builds upon emerging literature on Shadow banking and empirical literature on global imbalances and global financial flows. The aim of the thesis is to test three hypotheses, which relate global financial flows to lending, change in cross-border bank liabilities, and shadow banking, respectively. The second and third hypotheses are tested on gross capital flows, which, in contrast to net flows, better reflect financing activities. The results suggest that Shadow banking activities are related to higher gross capital flows in periods, when this sector is growing. These flows, however, tend to dry up when Shadow banking activities level off or decline. Among other important factors is the output growth differential and global risk aversion.

La libéralisation financière a été marquée dans de nombreux pays émergents par l’implantation massive de banques étrangères. A ce jour, les banques étrangères occupent une place dominante dans le secteur bancaire de ces pays et, cela soulève de nombreuses interrogations relatives aux effets sur la stabilité et le développement du système financier. L’objectif de cette thèse est donc d’étudier l’impact des banques étrangères sur l’efficacité du système financier et, de mettre en évidence le rôle de ces banques dans la survenance des crises et la transmission de chocs externes dans les pays émergents. Nous montrons ainsi que les banques étrangères contribuent à améliorer l’efficacité du système financier à travers la transmission de meilleures techniques d’évaluation et de gestion de risque. Cependant, elles sont apparues comme un vecteur de transmission de chocs externes. Cela nous amène, au regard de l’inadéquation du dispositif de surveillance prudentielle, à mettre en avant un cadre de coopération internationale dans la résolution des crises. Il s’agira donc de coordonner l’action collective en impliquant les autorités de régulation, les institutions financières internationales et les acteurs privés que sont notamment les banques de dimension systémique. / The financial liberalization in emerging countries has been marked by the growing rate of foreign banks presence. According to the increasing role of foreign banks in emerging markets, the aim of this thesis is to highlight the impacts on financial development and financial stability. It focuses mainly both on the implications of foreign banks competition on the efficiency of the financial system and on the fact that these banks can increase the financial crisis or convey external shocks. We show that foreign banks play a large part in improving financial efficiency through the best practices introduction in risk management. However, these banks have emerged as a vector of external shock transmission. This leads us, given the banking system regulation inadequacy, to promote a greater international cooperation in the crisis resolution based on national regulators, international financial institutions and multinational banks.

This diploma thesis deals with the acquisition of companies by means of the Leveraged Buyout (LBO) method. This method differs in many respects from the standards M&A. This work examines the specific features of the given business transactions from the viewpoint of the target companies, procedures and entities involved in these transactions. As the key element of the LBO method is the debt financing of the acquisition, the work also deals with this aspect and evaluates the positions of the creditors from the viewpoint of the influence on the stability of the financial system. The thesis further analyses the question whether the LBO method has an effect leading to an increased effectiveness of processes in a company, or whether, conversely, the proceeds of acquisition investors are a consequence of a transfer of values from other entities. The text is based on available theoretical and empirical sources which are supplemented by the author's analyses.

The purpose of this thesis is to offer a contemporary overlook on the widely discussed and problematic topic of bankong crises. This analysis gives a list of banking crises which have ocurred since the 90s. up to now, their causes and definitions, and explains some important macro- and microeconomic reasons for their occurrence.It also shows how current economic theory describes the causes and nature of financial instability, with emphasis on its real effects and high economic, as well as social costs. Based on these findings, this paper offers possible resolutions of problems of the financial system and methods of its stabilization with the aim to prevent future crises. A separate chapter is dedicated to the crises in Argentina 2001, the nordic countries in the late 80s/early 90s, and the Czech republic during its transition period.

The thesis deals with the interaction of monetary and macroprudential policy, or with the compatibility of the objectives of these policies in the Czech Republic. The main attention is given to the use of interest rate instruments for the purpose of achieving financial stability during the accumulation phase of cyclical dimension of systemic risk. For this purpose the crucial item is the relationship of financial and price stability in the economy. On the Czech economy data is therefore tested the relationship between credit activity and asset prices, to be subsequently quantified the relationship between the prices of selected assets and consumer prices. The model results open the door to greater use of industrial producer price index for the coordination of monetary and macroprudential policy. The thesis for the same reason also recommends continuing research into the development of the general price level during the financial cycle.

The subject of the presented thesis is the relationship between monetary policy executed within inflation targeting, asset prices and financial stability in the broader sense in order to identify key problems of the current approach and draw some conclusions on how inflation targeting could possibly further evolve. Flexible inflation targeting remained the best available monetary policy framework, despite some revisions are apparently needed. It turned out, that changes in the financial sector have much greater impact on economic activity, than previously thought, and which the new approach will need to take into account.
