Verifica-se que a busca pelo alcance das metas pré-estabelecidas para o aumento de preços implicou custos substanciais em termos de crescimento do produto interno da economia. Apresentam-se os fundamentos teóricos nos quais se baseia a proposição deste sistema de política monetária, atentando para a maior complexidade da condução do regime de metas de inflação em economias emergentes. Por fim, são descritas as peculiaridades da economia brasileira que, em conjunto com o conservadorismo do Banco Central na condução da política monetária, tornam elevado o custo de atendimento das metas de inflação em nosso país / Abstract: This work intends to assess inflation-targeting framework performance in the Brazilian economy. It finds that the Central Bank?s single objective to reach the inflation targets leaded the country to face substantial costs in terms of output and employment growth. This work presents the theoretical fundamentals that support this type of monetary policy framework, attempting for the higher degree of complexity regarding the operation of inflation-targeting in emergent market economies. Finally, it describes some particular characteristics of the Brazilian economy that, in set with the Central Bank orthodoxy in the operation of monetary policy, increased the costs of reaching inflation targets in our country / Mestrado / Politica Economica / Mestre em Ciências Econômicas

A intervenção no Banco Santos, em novembro de 2004, propiciou o surgimento de uma crise de liquidez em um segmento bem delimitado do mercado bancário brasileiro. O presente estudo procurou caracterizar e dimensionar o fenômeno com base em dados contábeis e informações publicamente disponíveis de 84 instituições do mercado. Utilizou-se a análise gráfica associada à análise de correlação para avaliar o comportamento dos saldos das contas Depósitos antes e após a intervenção. Como resultado, os bancos foram segregados em 5 grupos. O grupo que agregou os maiores bancos do mercado passou a ser o grupo de controle para a análise. A delimitação do grupo dos bancos, presumivelmente, contagiados (grupo de estudo) possibilitou avaliar a evolução dos resgates de depósitos e o papel das carteiras de crédito e de títulos como provedoras de liquidez. A análise realçou a importância dos depósitos compulsórios sobre depósitos a prazo como reserva de liquidez. Determinou-se também o volume de créditos cedidos ao longo do período. Concluiu-se que houve uma mudança no perfil das carteiras de crédito dos bancos afetados, com um aumento do percentual aprovisionado para risco de crédito, aproximando-o dos valores do grupo de controle, que utiliza critérios mais conservadores. Procurou-se, por fim, cotejar os eventos observados e as características do sistema financeiro brasileiro com o arcabouço teórico e empírico existente, principalmente em relação a dois aspectos: fundamentos que justificam o exercício da supervisão bancária e teoria das cascatas de informações analisada no âmbito das corridas bancárias. / The intervention on a small bank (banco Santos), in November 2004, has provoked a liquidity crisis on a specific segment of the Brazilian banking market. The objective of this case study has been to assess and characterize the phenomenon, based on balance sheet data and public information about 84 financial institutions of the market. Through graphical analysis associated with statistical correlation analysis, the behavior of the deposit account, before and after the intervention, was determined. As a result banks have been classified on five different groups. The group with the biggest banks was designed as the control group and banks that have showed loss of deposits and could have been, potentially, affected by a liquidity crisis were denominated as study group. The definition of the, presumable, contaminated group of banks has permitted to assess the evolution of deposits? withdraws as well as the role of the credit and security portfolios as providers of liquidity. The analysis has shown the importance of the reserve requirements over time deposits as a liquidity reservoir. It has also been determined the volume of credit transferred along the period of analysis. The conclusion is that the credit loss provision has augmented, getting closer to the values of the control group that uses more conservative provision standards. This study has also evaluated the observed events and the characteristics of the Brazilian financial system, with theoretical and experimental background, mainly focusing two aspects: fundaments that justify the exercise of banking supervision and the theory of information cascades on basis of the bank runs.

A Resolução 3.380 do Banco Central do Brasil, de 29 de junho de 2006, determina que, até o final de 2007, todas as instituições autorizadas a funcionar pela referida Autarquia deverão implementar estrutura de gerenciamento do risco operacional, representando mais um passo no processo de adesão do Brasil ao Novo Acordo de Capitais da Basiléia. Os objetivos desta dissertação são estudar o processo de estruturação de unidade de gestão de riscos operacionais e identificar referencial teórico que permita embasar a estruturação de unidades de gestão de risco operacional em bancos. De modo a atingir os objetivos propostos, foi realizado estudo de caso exploratório de um banco escolhido em função de sua representatividade no cenário nacional. Os resultados da pesquisa sugerem que o referencial teórico sobre estruturas organizacionais pode ser muito útil na estruturação de unidades de gestão de riscos operacionais em bancos, devido ao fato do arcabouço conceitual sobre unidades de gestão de riscos operacionais ainda ser muito incipiente. / The resolution 3380 of the Brazilian Central Bank, as of June 29th 2006, determines that, until the end of 2007, all authorized institutions must implement an operational risk management structure, representing another step in the brazilian compliance process to the New Basel Capital Accord. The objectives of this work are to study the structuring process of an operational risk management unit and to identify theoretical references to support this structuring process in banks. In order to achieve the considered objectives, a case study was conducted on a bank chosen in function to its relevance in the national scene. The results of the research suggest that the theoretical references on organizational structures can be very useful in structuring operational risk management units in banks, due to the fact that theoretical background on operational risk management units are still incipient.

O mercado financeiro brasileiro é caracterizado pela elevada concentração bancária, onde os cinco maiores bancos detêm a maior parte dos ativos financeiros. Bancos pequenos e médios têm que disputar espaços com os grandes conglomerados financeiros. Questões como economia de escala e custo de observância às normas são essenciais para a sobrevivência destas instituições menores. A aprovação para a constituição de instituições financeiras no País é dada pelo Banco Central do Brasil, que estabelece os valores de capital mínimo, em função da modalidade de instituição. Por sua vez, o Comitê de Supervisão Bancária de Basiléia estabelece os padrões máximos de alavancagem, o que indica qual volume de carteira pode ser contratado, dado este patrimônio. Este trabalho tem como objetivo verificar se os valores de capital mínimo estabelecidos pelo Banco Central do Brasil são compatíveis com a estrutura de custo das instituições, e com o objetivo de retorno dos acionistas. Serão utilizados dados dos demonstrativos das instituições financeiras e, com base em modelo de regressão de dados em painel estático, será construída uma curva de retornos em função do porte da instituição. Este retorno, comparado com o custo de capital calculado pelo CAPM indicará a partir de que porte uma instituição financeira é viável. / The Brazilian financial market is characterized by its huge banking concentration, where the five largest banks hold most part of the assets. Small and medium size financial institutions have to compete with the larger financial conglomerates. Economy of scale and cost of compliance issues are essential for the survival of the smaller institutions. The approval of a new financial institution is given by the Brazilian Central Bank, who establishes the minimum equity value, depending on the type of institution intended. Additionally, the Basle Committee on Banking Supervision fixes the maximum leverage standards, what indicates the maximum credit portfolio possible, given this equity value. This thesis aims to verify if the minimum equity value established by the Brazilian Central Bank is compatible with the banks operational cost and the shareholder return objective. Data of the financial statements will be used in conjunction with static panel regressions, to construct the return curve regarding the dimension of the institution. This will be compared with the shareholder cost of capital, estimated by de CAPM, to indicate the minimum dimension, which makes feasible the institution.

The financial crisis that started in 2007 has seen central banks play an unprecedented role both to ensure financial stability and to support economic activity. While the importance of the central bank in ensuring financial stability is well known (see e.g. Padoa-Schioppa (2014)), the unprecedented nature of the financial crisis led central banks to resort to new instruments for which the literature offered little guidance. This thesis aims to bridge this gap, using both theory and data to better understand one of the main instruments used by central banks: collateralized loans. The general contribution of the thesis is thus both retrospective and forward looking. On a retrospective point of view, it helps understanding the actions of the central bank during the crisis and the mechanisms involved. Looking forward, a better understanding of the tools used during the crisis allows to better inform future policies.The first chapter starts from the observation that the literature, starting with Bagehot (1873), has generally assumed that the central bank should lend against high quality collateral. However in the 2007-2013 crisis central banks lent mostly against low quality collateral. In this chapter, we explore when it is efficient for the central bank to relax its collateral policy. In our model, a commercial bank funds projects in the real economy by borrowing against collateral from the interbank market or the central bank. While collateral prevents the bank from shirking (in the spirit of Holmstrom and Tirole (2011)), it is costly to use as its value is lower for investors and the central bank than for the bank. We find that when the bank has high levels of available collateral, it borrows in the interbank market against low collateral requirements so that the collateral policy of the central bank has no impact on banks' borrowing. However, when the amount of available collateral falls below a threshold, the lack of collateral prevents borrowing. In this case, the collateral policy of the central bank can affect lending, and it can therefore be optimal for the central bank to relax its collateral requirements to avoid the credit crunch.The second chapter focuses on collateralized loans in the context of the euro area. According to the literature on optimum currency area, one of the main drawbacks of currency unions is the inability for the central bank to accommodate asymmetric shocks with its interest rate policy. Suppose that there are 2 countries in an economy and one suffers a negative shock while the other has a positive shock. Theory would suggest an accommodative policy - low interest rates - in the first country and a restrictive policy - high interest rates - in the second one. This is however impossible in a currency union because the interest rate must be the same for both countries (Mundell 1961, McKinnon 1963, de Grauwe 2012). In this chapter I show that collateral policy can accommodate asymmetric shocks. I extend the model of collateralized lending of the first chapter to two banks A and B and two collateral types 1 and 2 .I also introduce a central bank deposit facility which allows the interest rate instrument to be compared with the collateral policy instrument in the context of a currency area hit by asymmetric shocks. Macroeconomic shocks impact the investment opportunities available to banks and the value of their collateral and the central bank seeks to steer economy rates towards a target level. I show that when banks have different collateral portfolios (as in a monetary union where banks invest in the local economy), an asymmetric shock on the quality and value of their collateral can increase interest rates in the country hit by the negative shock while keeping them unchanged in the country with a positive shock.The third chapter provides an empirical illustration of this “collateral channel” of open market operations. We use data on assets pledged by banks to the ECB from 2009 to 2011 to quantify the “collateral substitution / smoother transmission of monetary policy” trade-off faced by the central bank. We build an empirical model of collateral choice that is similar in spirit to the model on institutional demand for financial assets of Koijen (2014). We show how the haircut of the central bank can affect the relative cost of pledging collateral to the central bank and how this cost can be estimated using the amount of assets pledged by banks. Our model allows to perform a broad set of policy counterfactuals. For example, we use the recovered coefficient to assess how a 5% haircut increase on all collateral belonging to a specific asset class (e.g. government bonds or ABS) would affect the type of collateral used at the central bank. The final chapter focuses on the use of loans as collateral by banks in the euro area. While collateral is generally viewed as consisting of liquid and safe assets such as government bonds, we show that banks in Europe do use bank loans as collateral. We identify two purposes of bank loan collateral: funding and liquidity purposes. The main distinction between the two purposes is with respect to the maturity of the instruments involved: liquidity purposes refer to the use of bank loans as collateral to obtain short term liquidity and manage unexpected liquidity shocks. In practice the central bank is the main acceptor of these collateral. The second type of use is for funding purposes, in which case bank loans are used as collateral in ABSs or covered bonds. The collateral in these transactions allow banks to obtain a lower long-term funding cost. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

This master thesis deals with current monetary policy in the world. The monetary policy belongs to the basic components of the economy and the economic policy. In today`s world economy, still recovering from the recent financial and economic crisis, many people look up to the monetary policy as a possible remedy for standstill economy. At first, this thesis presents standard monetary policy. Then, the analysis of the current monetary policy in the centres of the world economy, which means the USA, Europe and Japan, is carried out. From the analysis the main problems of current monetary policy emerge and then new tools and solutions implemented by various central banks for the purpose of solving these problems are analysed. At the end other possibilities of the monetary policy are presented in theory.

This thesis explores some different dimensions of business cycle analysis and monetary policy,in closed and open economies. In the first chapter, I develop a model to analyze the roleof research and development in the US business cycle, and its ability to produce macroeconomicfluctuations by generating expectations of future productivity gains. In the secondchapter, I empirically investigate how changes in central bank transparency affects financialmarkets response to central bank announcements in the United Kingdom. Finally, in thethird chapter, I analyze some heterogeneities in the international spillovers of central bankannouncements, focusing on the behavior of exchange rates and international capital flows.The first chapter studies the role of R&D-based innovation within the US business cycle. Thechapter builds on the idea that temporary business cycle frequency contractions can result inprolonged medium-run slowdowns, if an economy’s technological growth is generated by asector of profit-maximizing innovators. In order to analyse the business cycle spillovers oninnovation activity, this chapter analyzes the contribution of R&D-based innovation to USbusiness cycle dynamics combining techniques from the empirical and theoretical literature.First, using a Bayesian VAR identified with a Cholesky recursive formulation, the papershows that innovation shocks are generally inflationary and generate rises in hours worked.Second, the paper introduces a medium-scale New-Keynesian model of creative destructionthat can rationalize these facts. In the model, a sector of profit-maximizing innovators investsin R&D and endogenously generates productivity gains, ultimately determining theeconomy’s growth rate. The estimated responses to innovation shocks are characterized bypowerful wealth effects that offset the contractionary spillovers on the labour market conventionally associated with productivity increases. The estimation results suggest that thebulk of the productivity slowdown is due to a decrease in the innovation’s ability to generateproductivity gains. These findings support the view of the productivity slowdown as astand-alone phenomenon in the US business cycle as opposed to a byproduct of the GreatRecession.In the second chapter (jointly written with Andrzej Szczepaniak), we investigate the impactof monetary policy transparency measures on the relevance of the information effect channelof central bank communication. Our paper focuses on the switch in the Bank of England’scommunication strategy, occurred in August 2015, from a multi-day to a single-day releaseschedule. Before August 2015, the minutes of the monetary policy committee and the inflationreport (i.e. the Bank’s analysis of the economic outlook), were published only someweeks after the monetary policy decision. By contrast, after August 2015, the Bank of Englandstarted releasing all accompanying documents alongside the policy rate announcement,in the attempt to increase the transparency of its policy-making process.To this purpose, we construct a market surprise series for each one of the three communicationdocuments of the Bank of England (the monetary policy decision, the minutes of themonetary policy committee, and the economic outlook report) in order to evaluate the effectof central bank communication on agents’ expectations. The chapter builds on the idea thatmarket responses to central bank releases can be due either to unexpected deviations from thecentral bank’s policy rule (the policy component of the surprise), or to the revision of agents’expectations about future inflation (the informational component of the surprise). These twocomponents can be identified based on the associated reaction of equity prices. In the chapter,the policy component of the policy announcement is identified as an unexpected increasein the policy rate which results in a decline in equity prices, and the informational componentas an unexpected increase in the policy rate which results in a rise in equity prices, inaccordance with the methodology introduced by Jarocinski and Karadi (2020). We provideevidence that the informational component is a key driver of the financial market response tocentral bank communication. Before August 2015, according to our results, the informationeffect accounted for approximately two thirds of the interest rate surprise, the inflation expectations,and the equity price variation on the release days. However, we find that the switchfrom a multi-day release schedule to a single-day communication strategy markedly reducedthe importance of information effects. Our findings suggest that the degree of transparencyof a central bank’s policies significantly affects the quantitative relevance of the informationeffect and the associated asset price response.The third chapter (jointly written with Andrzej Szczepaniak), analyzes some of the internationalspillovers of central bank communication. The chapter highlights that the policy andthe informational component of central bank announcements entail different open economyspillovers. Namely, when unexpected increases in the US policy rate are associated withincreases in equity prices, the US dollar depreciates. We argue that this phenomenon occursbecause central bank information shocks affect investors’ risk perception. In response tofavorable central bank information shocks, we observe downward revisions of the level offinancial risk perceived by investors, which lead capital to flow towards emerging marketsand riskier asset classes. Conversely, in response to adverse central bank information shocks,we observe upward revisions of the level of financial risk perceived by investors, which leadcapital to flow towards the US and safer asset classes, causing an appreciation of the US dollar.In support to this hypothesis, we provide evidence of large spillover effects onto globalsafe-haven currencies, risk premia, cross-border credit, risky assets, and ultimately, on globaleconomic activity. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished
