The recent economic and financial turmoil has led central banks around the world to heavily utilize unconventional monetary policy measures. Unconventional in this sense means a deflection from traditional central bank policy measures, i.e. interest rate innovations. Although these measures were widely discussed, the uniformed, coherent and comprehensive framework of such measures is still missing. The aim of this thesis is to establish the framework for possible classification of such policies together with transmission channels to the real economy. The empirical part examines the impacts of unconventional policies on real data using vector autoregression and vector error correction models. This analysis is based on monthly data period between 1999 and 2013, which is strongly affected by implementation of the unconventional policies in its second half. The last section examines the possible future of these policies as a normal instrument of central banks and describes their main challenges and shortcomings.

Les trois chapitres de cette thèse ont pour objectif de contribuer à une meilleure compréhension de la manière dont les politiques non-conventionnelles affectent les prix d’actifs. Ils revisitent également de manière empirique la question de l’impact de l’offre sur les prix d’actifs, et plus généralement des limites imposées à l’arbitrage, des frictions dans la réallocation des portefeuilles. Chaque chapitre présente de nouvelles données permettant de quantifier les mécanismes à l’œuvre dans le cas du programme d’achat d’actifs de l’Eurosystème (APP). Le chapitre 1 propose un modèle de portefeuille simple permettant de penser les mesures non conventionnelles dans un cadre cohérent. Les exercices empiriques confirment l’existence de plusieurs canaux de transmission des prix et évaluent l’impact de l’APP. Le chapitre 2 jette un nouvel éclairage sur le canal du rééquilibrage de portefeuille. Les fortes frictions liées à la réallocation, la forte demande d’“habitat préféré” et le faible niveau de substituabilité entre actifs permettent d’avoir un impact sur les prix, tout en limitant possiblement les retombées sur l’économie. Le chapitre 3 suggère que l’effet des achats de titres passe également si ce n’est en premier lieu par l’augmentation du coût d’emprunt de ces titres, ce qui a des répercussions sur la dispersion des taux du marché monétaire à court terme et pourrait rendre difficile à l’avenir la transmission de la politique monétaire conventionnelle si les taux autrefois considérés comme sans risque et contrôlables par la banque centrale ne pouvaient pas être contrôlés aussi précisément qu’auparavant. / The three chapters contained in this PhD thesis aim at contributing to a better understanding of how unconventional monetary policies and in particular asset purchases affect asset prices. As such, they also revisit the question of the impact of bond supply on bond prices, and more broadly the questions of limits to arbitrage, frictions in portfolio reallocation and the role of intermediaries. Each chapter brings new original data to quantify the effect on bond prices, on the short term rates, and on the portfolio reallocation of investors. Chapter 1 built a simple portfolio model allows to think of them in a consistent framework, and suggests that the type of asset purchased, the degree of risk aversion or how assets covary are important. The empirical exercises confirm the existence of several transmission channels to prices and assess the impact of the European APP. Chapter 2 sheds a new light on portfolio rebalancing in terms of asset classes and shows it is more limited than previously thought. Heavy frictions to reallocation, strong “preferred habitat” demand and low level of substituability between assets allow for price impact of central bank asset purchases but at the same time possibly limit the spillovers on the economy. The main channel through which APP affects price might be even be more indirect that one thought: chapter 3 suggests that it might come from reducing asset supply and increasing the cost of borrowing them. This has repercussions on the dispersion of short term money market rates and might be challenging in the future if rates once considered as risk free and controllable by the central bank cannot be controlled as precisely as before. In other terms, controlling the long end of the yield curve might in part comes at the cost of loosing part of the control on the short end.

The main goal of this thesis is comparison of FEDs monetary policy in times of Great Depression and financial crisis 2007 -- 2009. Both of them began when the speculative bubble burst (in the first case it was in stock market, in the second one it occurred in real estate market). The effect of speculative bubbles bursting had very negative impact on global economic system. The FEDs monetary reaction to the both crises was very different. It differentiates in many aspects -- in times of Great Depression FED acted passive -- did not provide large open market purchases, did not lowered the interest rate quick enough to avoid the money stock fall-down. In current crisis, FED did not repeat mistakes made during Great Depression. In response to the market pressure, FED created several unconventional tools to support liquidity of depository institutions, primary dealers and commercial paper market. Via these new-invented programs, FED did not allow the money stock to fall and as the financial strains eased, they slowly disappeared. Besides these liquidity programs, FED supported economy with fast interest rate lowering and providing quantitative easing. Steps taken by FED helped to stabilize financial markets.

Este trabalho tem como objetivo principal explorar e apresentar, do ponto de vista doutrinário, legal e estatístico, três pontos centrais que carecem da atenção dos operadores do direito. O primeiro, relativo ao acesso à justiça e suas peculiaridades em apertada síntese, especialmente com olhos voltados para a retroalimentação processual, típica das sociedades de massa. Neste tópico, avaliamos dados estatísticos colhidos e fornecidos pela Comissão Especial de Juizados Especiais do Tribunal de Justiça do Estado do Rio de Janeiro. O segundo, relativo à efetividade e instrumentalidade do processo como garantias fundamentais do processo voltadas à preservação da prestação jurisdicional comprometida com a duração razoável do processo e na preservação do Estado Democrático de Direito. Por fim, o terceiro busca a análise da questão relativa aos aspectos doutrinários da flexibilização procedimental como mecanismo para a preservação da celeridade. Analisando o enfoque do Direito Inglês e Português, bem como aspectos ligados ao gerenciamento do processo e adequação, proponho a flexibilização em sede dos Juizados Especiais Cíveis como medida de concreta preservação da informalidade. / This study aims to explore and present,by the doctrinal point of view, legal and statistical, three central points that require the attention of law enforcement officers.

Non-standard Monetary Policy Instruments of Central Banks Abstract The aim of this study is to analyze non-standard monetary instruments of central banks and their impact on the example of concrete use of these instruments by the Czech National Bank and the European Central Bank. The first part of this study defines the essence, the implementors, the tasks, and the objectives of the monetary policy. Its tools are also disassembled, both standard and nonstandard. From non-standard instruments, closer attention is paid to the theoretical definition of quantitative easing, negative interest rates and long-term maintenance of the exchange rate commitment. I also deal with the legal anchor, organization, purpose, history, and concept of the monetary policy of two selected central banks, namely the CNB and the ECB. The next part of the study presents the concrete form of non-standard measures used by the CNB and the ECB, it deals with the specific reasons that the central banks led to their implementation, the objectives with which they were adopted and the impact these measures had on the Czech economy and the euro area. Based on the analysis, it is possible to confirm the tested hypothesis that the Czech National Bank and the European Central Bank have succeeded in meeting the objectives set before their...

Les quarante-cinq premières années de la Troisième République se caractérisent par une politique de laïcisation touchant de nombreux domaines, à commencer par l’éducation, politique qui culmine en 1905 avec la loi de Séparation des Eglises et de l’Etat. La ville de Lyon, qui avait connu durant les deux premiers tiers du XIXème siècle une renaissance particulièrement forte du catholicisme, se manifestant par la création d’œuvres dynamiques, se voit confrontée en retour à une vague particulièrement puissante d’anticléricalisme. La confrontation des deux groupes idéologiquement opposés, que l’on peut nommer « clérical » et « anticlérical », détermine toute une succession de crises, d’accalmies, de recompositions, dont les spécificités lyonnaises ne pas toujours liées à celles du contexte national. Dans ses aspects concrets, cette lutte n’est pas perçue de la même façon chez tous ceux qui se rassemblent autour de l'étiquette « anticléricale » : les ouvriers de la Guillotière n’ont pas les mêmes griefs à formuler contre le clergé que les radicaux du « Comité de la rue de Grôlée ». Néanmoins, autant l’anticléricalisme reste assez simple à définir, autant le cléricalisme se révèle plus difficile à appréhender : il dépend d’abord du regard de l’autre, notamment de l’anticlérical. Les diverses manifestations de défense religieuse d’un catholicisme qui se perçoit alors volontiers comme une citadelle assiégée, les multiples attaques contre le clergé, voire contre la religion, des hommes au pouvoir, s’inscrivent à Lyon, sur la longue durée, dans le droit fil d’une série de luttes, d’insurrections et de répressions, dont chaque camp revendique - ou non - la postérité idéologique. / One of the main features of the first forty five years of the Third Republic is a policy of secularization in many fields, beginning with education and reaching its climax in 1905 when the law on the separation between church and state was passed (given the French context at the time, it especially targeted the catholic church). During the first two thirds of the XIXth century Lyons had known a strong revival of Catholicism which manifested itself by the creation of dynamic charitable organizations. The town then had to face a sudden increase of anticlericalism. The confrontation between two groups that were politically opposed – let us name them “clerical” and “anticlerical” – sparked crisis after crisis, followed by lulls and reconstructions, all these being sometimes different from what was happening at the national level, due to the particular characteristics of the town. In concrete terms not all that had gathered under the banner of anti-clericalism held the same opinion about the struggle: the workers in the district of La Guillotière did not hold the same grievances against the clergy as the radicals in the “rue de Grôlée committee”. Yet, although anticlericalism can be easily defined, clericalism proves more difficult to apprehend: in the first place it depends on the perception the others, and more specifically those who support the anticlerical faction, have of us. Catholicism then tends to see itself as a besieged fortress and the different manoeuvres set up to defend its religion, the numerous attacks against the clergy, even against religion from men in power are, in Lyons, quite in keeping with a long succession of struggles, insurrections and suppressions of which each side claims -or does not claim- the ideological posterity.

The thesis deals with relation between central bank independence and accountability. The relation is examined on example of quantitative easing implemented in the period 2005 - 2016 by the European central bank and the Federal Reserve System. From the theoretical and practical point of view the thesis proves that the relation between central bank independence and accountability are influenced by the specification of targets of monetary policy to a great extent. The thesis also proves that the specific definition of both central bank independence and accountability influenced the characteristics of quantitative resp. credit easing. Moreover, such monetary policy can potentially endanger the independence of both central banks in many ways. Thus, the implementation of quantitative easing itself and its potential consequences evidences that the contemporary conception of central bank independence and accountability is insufficient and needs to be reviewed.

在面臨2008年金融危機後嚴峻之需求面衝擊下，多國央行紛紛調降利率，甚至調降至零利率，以期望國家能盡速脫離經濟衰退。在利率調降的過程中，由於受零利率下限的限制，單純藉由傳統貨幣政策之調控，仍可能無法使經濟從嚴峻的需求面衝擊下恢復。因此，非傳統貨幣政策也在美國、日本、英國、歐元區等國家被央行所採行做為對抗經濟衰退的政策工具。在此背景下，我們想了解如何實施最適非傳統貨幣政策。 在最適貨幣政策理論發展中，最適傳統貨幣政策發展較早，因此也較為完備。而在最適非傳統貨幣政策方面，前瞻指引(forward guidance)這項政策工具已被引入最適理論中來進行討論，但量化寬鬆(quantitative easing)直至今日還未被引入最適理論中來討論。 因此，本文建構一個封閉的新興凱因斯模型(New Keynesian)，開創性的將量化寬鬆引入最適貨幣政策理論中，來討論最適傳統與非傳統貨幣政策，也藉此與過去文獻比較施行量化寬鬆與未施行量化寬鬆之影響。 / After financial crisis occurred in 2008, countries, such as United States of America, United Kingdom, Japan and the euro area, have been mired in slow economic growth, compared with long-term, and have confronted with severe negative demand shocks which can’t be offset by zero interest-rate policy. Under the circumstance where zero lower bound was present, unconventional monetary policy was implemented by central bank of each country to end up the economic recession prospectively. As a result, we are interested in how to implement optimal unconventional monetary policy. The literatures regarding implementing conventional optimal monetary policy under demand shock were developed maturely. Forward guidance, one of unconventional monetary policy, was already developed in field of optimal monetary policy under impacted by demand shock, but quantitative easing has not been conducted in the theory of optimal monetary policy so far. Thus, we construct a close-economy by New Keynesian model to conduct quantitative easing into the theory of optimal monetary policy to discuss the optimal conventional and unconventional monetary policy, and to compare the difference corresponding to the previous literatures which without quantitative easing.

The aim of this thesis is to show how the unconventional monetary policy rounds of Quantitative Easing introduced in the United States between 2008 and 2014 have led to an increase in wealth inequality. The need for the thesis arises due to the uncharted nature of QE and because of more and more information is surfacing to light which points to this connection. By analysing the distribution of these funds and adding it to the then base distribution of money supply, this study was able to determine a significant 10 % increase in the Gini Index. Furthermore it highlights how a large portion of wealth was transferred from the middle class over to the top 5 % income households. Starting from a set of assumptions the calculation is performed by extrapolating the data required and by isolating the system from any external variables. The result is a theoretical model meant to describe the mechanism that links Quantitative Easing to wealth inequality. Moreover a detailed comparison is provided with the effect of a conventional monetary policy such as Open-Market Operations. Finally solutions to this issue are being discussed from economical, political and fiscal standpoints.
