Even though major advances in economic theory and modelling have in some cases furthered our understanding of how the economy works, the system as a whole has become more complex. If policymakers had perfect knowledge about the actual state of the economy, the various transmission mechanisms as well as the true underlying model, monetary intervention would be greatly simplified. In reality, however, the monetary authorities have to contend with considerable uncertainty in relation to the above-mentioned factors. This said, uncertainty has mostly been neglected in both the theoretical and empirical literature focusing on monetary policy analysis. Nonetheless, findings from a review of theoretical literature that does exist on this topic suggest that optimal central banks act more conservatively when faced with uncertainty. Similarly, empirical findings from the literature also favour conservatism. However, there is some evidence to suggest that this is not always the case. These results suggest that central banks do not always act optimally when faced with uncertainty. The limited number of industrial country cases examined prevents any generalised view from emerging. If anything, the literature findings suggest that central bank behaviour differs across countries. This thesis aims to contribute to the empirical literature by studying the effects of uncertainty on monetary policy in the developing country case of South Africa. In simplest terms, the thesis seeks to establish whether or not the South African Reserve Bank (SARB) responded optimally to uncertainty as suggested by theoretical models thereof. To this end, the thesis employs a theoretical model which resembles a structural rule-based approach. The optimal interest rate rule was derived given a set of structural equations relating to demand, the Phillips curve and the real exchange rate. To incorporate uncertainty, it is assumed that the coefficients are dependent on the variances of the exogenous variables, namely inflation, the output gap and the exchange rate. The uncertainty adjusted model allows us to investigate whether monetary policy is more aggressive or passive when uncertainty about the relevant exogenous variable increases. Inflation, output gap and exchange rate uncertainty estimates were derived through GARCH-model specifications related to the structural equations as defined in the theoretical model. The investigation considered both indirect and direct uncertainty effects with a sample period stretching from 1990 to 2011. The findings reported in this thesis provide strong evidence in support of the notion that uncertainty plays a significant role within the South African monetary policy landscape and contributes towards explaining the SARB’s actions. Furthermore, the results suggest that the SARB did in fact act optimally in responding more conservatively to target variable fluctuations on average. Also, the findings could potentially strengthen the case for inflation targeting as a monetary policy regime, as the results indicate a marked decline in the effects of uncertainty under inflation targeting than before. / Economics / D.

The objective of the thesis was to study monetary policy frameworks in developing countries. The thesis focused on three aspects of the monetary framework; the degree of central bank independence, the monetary policy strategy and the exchange rate regime. The research applied quantitative empirical analysis and in-depth case studies on Egypt, Jordan and Lebanon. The empirical research investigated three areas: 1) the phenomenon of ‘fear of floating’ and the correlation between exchange rate and macroeconomic volatility; 2) the degree of monetary policy independence in developing countries in the context of their increased integration into the global economic system; and 3) the degree of central bank independence and how it impacts both ‘fear of floating’ and monetary policy independence. The case studies allowed for an in-depth understanding of the process of setting monetary policy and the constraints under which it is formulated in developing countries. The results that emerged from the quantitative analysis highlight the impact of central bank independence in influencing the other aspects of the monetary framework, as it can mitigate fear of floating and contribute to increased monetary policy independence of world interest rates in developing countries. The case studies detailed the evolution of monetary frameworks in three countries with varying degrees of central bank independence. The degree of central bank independence increased in Egypt and Jordan as a result of severe currency crises in each country, while Lebanon provides a very different example of a developing country with an independent central bank since its inception. The conclusions that emerged from the cases suggest that central bank independence is critical in achieving exchange rate and price stability; however, developing countries should avoid focusing on exchange rate stability at the expense of other considerations for extended periods of time. In that, the results point to the benefits of proactively and pre-emptively managing the exchange rate regime. The cases also highlight the importance of the coordination between fiscal and monetary policies, as conditions of fiscal profligacy can undermine even the most independent central bank.

The econometric method used for analysis consisted of applying Granger causality tests using data from the Central Bank of Brazil. We conclude that the amount of money were defined by demand and had no impact on the determination of the nominal product. The central bank, in turn, provided the necessary reserves in accordance to the volume of deposits. Together, these results provide support to the notion of endogenous money supply in the period. / Considerando a evolução do crédito e crescente pressão inflacionária observados no Brasil entre 2007 e 2015 esta pesquisa investiga como o Banco Central do Brasil, dada sua missão de controlar a inflação, atuou na provisão de reservas para suportar o crescimento do crédito observado no período recente. O método econométrico empregado para análise foi composto por aplicação de testes de causalidade de Granger utilizando dados do Banco Central do Brasil. Resulta da pesquisa que a quantidade de moeda foi definida pelas necessidades da demanda e não teve implicações na determinação do produto nominal. O banco central, por sua vez, forneceu as reservas necessárias conforme o volume de depósitos. Em conjunto, estes resultados corroboram a noção de oferta monetária endógena no período.

The paper investigates the role of central bank communication for monetary policy implementation. Firstly, we use a multi-disciplinary approach to disentangle several problematic contingencies of central bank communication, analyzing from this perspective the role of complex phenomena such as public opinion, perceptions, beliefs, framing, subjective probability, rhetoric, persuasion, cognitive limits and distortions, psychological and cultural biases etc. The result is a comprehensive survey of theory and practice in central bank communication, from the perspective of political science, social-psychology and media studies. Secondly, we attempt to draw on more psychological realism to central bank communication in the context of financial crises, using a parallel with risk management in the case of natural disasters. Thirdly, we conceive central bank information as a public good, thereby we construct a novel schematic model of supply and demand based on two respective behavioral logistic functions, in order to derive central bank informational equilibrium. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

During the Great Recession of 2007 and 2008, liquidity and credit dried up, threatening the stability of financial institutions, particularly the banking firms. Traditional source of funds from the last resort, the Discount Window of the Federal Reserve System, failed to remedy the liquidity problem. To assuage the liquidity and credit problem, the Federal Reserve System established several emergency lending facilities and provided unprecedented amount of loans to the banking industry. Using a dataset published by Bloomberg LLP in the aftermaths of the financial crisis, which contains daily loan balances from the Fed, I conduct an event study to test whether financial markets are efficient in reflecting all public, anticipated and classified information in security prices. The most important contribution of this dissertation to the finance discipline and literature is the investigation and analysis of the Fed’s unprecedented loans to the banking industry during the Great Recession and the market reaction to it. The second major contribution of this study is the empirical test of strong form efficient market hypothesis, which has not been feasible due to legal data challenges. This dissertation has other contributions to the finance discipline and banking research. First, I develop an algorithm for measuring the amount of borrowing by banks. Second, I introduce a new “loan balance” ratio to traditional list of bank financial ratios. Third, I use event study methodologies to allow for cross-correlation, heteroscedasticity and event induced-variance change in studying US banks’ performance during the Great Recession.
