Ensaios sobre política monetária e fiscal no Brasil

Caetano, Sidney Martins January 2007 (has links)
Esta tese apresenta três ensaios sobre política monetária e fiscal dentro do atual regime de metas de inflação. O primeiro ensaio buscou estudar uma possível integração monetária-fiscal ao determinar uma regra ótima de política monetária com restrição fiscal, analisando os efeitos de diversas preferências sobre a regra ótima em função da alteração dos pesos dados para os desvios da razão superávit primário/PIB em relação à sua meta pré-estabelecida. Os resultados mostraram que a regra ótima obtida apresenta uma resposta negativa das taxas de juros aos choques na relação dívida/PIB. Ainda, superávits primários/PIB maiores permitiriam reduções maiores nas taxas de juros e proporcionais aos pesos que essa variávelobjetivo teria na função de perda social. Do ponto de vista tradicional do mecanismo de transmissão da política monetária, a resposta positiva das taxas de juros a uma desvalorização real do câmbio e a uma elevação do prêmio de risco seria mantida. Portanto, os resultados sugerem que a adoção de uma meta explícita para o superávit primário/PIB tem conseqüências positivas sobre a regra ótima de política monetária e para a redução da taxa de juros, bem como na eficiência do atual instrumento de política monetária. O segundo ensaio buscou analisar a relação risco default através do modelo de regressão beta, bem como os impactos que os superávits primários podem trazer sobre o prêmio de risco e, consequentemente, sobre o câmbio. Do ponto de vista da relação default risk, ancorada no modelo de Blanchard (2004/2005), as estimativas baseadas no modelo de regressão beta para as quatro relações propostas neste ensaio apresentaram sinais estatisticamente significativos e compatíveis com a teoria. O fato interessante nos resultados referente ao período do regime de metas de inflação é que as estimativas indicaram uma relação direta e forte entre o superávit primário/PIB e a probabilidade de default; evidências que destacam a importância dos efeitos indiretos que o superávit pode gerar sobre o juro doméstico. O terceiro ensaio analisou a dinâmica discreta da taxa de juros SELIC-meta definida nas reuniões do Comitê de Política Monetária (COPOM). Dois métodos foram utilizados para estudar a possibilidade de o COPOM reduzir/manter/aumentar a taxa de juros básica: probit binomial e probit multinomial. Os resultados mostraram que os desvios de inflação e o hiato do produto são variáveis relevantes para explicar as decisões do COPOM. O modelo probit binomial aplicado para os casos de aumento e redução da taxa SELIC-meta mostraram que a inclusão da variável fiscal gerou melhores resultados. Para o caso agregado, método probit multinomial, os resultados indicaram que a inclusão da variável fiscal combinada com a expectativa de inflação gerou os melhores resultados relativamente aos demais casos. Assim, a resposta do COPOM a resultados fiscais bem como às expectativas do mercado quanto à inflação demonstraram ser os sinais que devem ser observados pelo mercado. / This thesis presents three essays on monetary and fiscal policy of the current regimen of inflation targeting. The first essay searched to study an integration monetary-fiscal when determining an optimal rule of monetary policy with fiscal restriction, analyzing the effect of diverse preferences on the optimal rule in function of the alteration of the weights given for the deviations of the surplus primary as a fraction of GDP in relation to its established targets. The results show that the gotten optimal rule presents a negative reply of the interest rates to the shocks in the debtto- GDP ratio. Primary surplus still bigger would allow bigger reductions in the interest rates and proportional to the weights that this variable-objective would have in the function of social loss. Of the traditional point of view of the mechanism of transmission of the monetary policy, the positive reply of the interest rates to a real depreciation of the exchange and to a rise of the risk premium it would be kept. Therefore, the results suggest that the adoption of explicit targets for the primary surplus in percentage of the GDP has positive consequences on the optimal rule of monetary policy and for the reduction of the interest rates, as well as in the efficiency of the current instrument of monetary policy. The second essay searched to analyze the relation default risk through of the beta regression model, as well as the impacts that primary surplus can bring on the risk premium and, consequently, on the exchange rate. Of the point of view of the relation default risk, anchored in the model of Blanchard (2004/2005), the estimates based on the beta regression model for the four relations proposals in the study had presented significant and compatible signals with the theory. The interesting fact in the results referring to the period of the regimen of inflation targeting is that the estimates had indicated a negative and strong relation between the primary surplus/GDP and the probability of default, evidences that detaching the importance of the positive and indirect impact of the surplus in relation to the interests rate domestic. The third analyzes the discrete dynamics of the SELIC interest rates-target defined in the meetings of the Brazilian Monetary Policy Council (COPOM). Two methods were applied in order to study the possibility of COPOM to reduce/maintain/increase the interest rates: probit model and multinomial probit. It was verified that the deviations of inflation and the GDP gap must be considered importants variables to explain the COPOM’s decisions. The probit model was applied to the cases of the increases probabilies and reduces probabilities showing that the inclusion of a fiscal variable generates better results. To the aggregated case, multinominal probit method, the results indicates that the inclusion of a fiscal variables combined with the inflation expectations generates better results than other possibilities. So, the responses of COPOM to the fiscal results as well as inflation expectations were the reals signs to be considered for the market.

Politique de ciblage d’inflation : règles de conduites, efficacité, performance / Inflation targeting policy : optimal rules, relevance, performance

Ftiti, Zied 24 February 2010 (has links)
Depuis 1990, bon nombres de pays industrialisés et émergents ont adopté la politique de ciblage d’inflation. Ce régime monétaire a été adopté sans théorie adjacente dans la mesure où il a démarré comme une solution alternative à la recherche sans fin d’un système d’ancrage nominal suite aux échecs répétés des politiques antérieurs. Ce retard théorique fait naître de nombreux débats économiques sur la conduite de ce régime monétaire dont les plus importants feront l’objet d’une discussion approfondie au sein de cette thèse. Dans un premier chapitre, nous définissons la politique de ciblage d’inflation. Dans un second chapitre nous abordons la question de la conduite optimale de ce régime d’un point de vue théorique et empirique. Nous montrons que la règle optimale est une règle à la Taylor de type Forward-Looking dont elle peut avoir un comportement asymétrique. Dans un troisième chapitre, nous abordons la question de l’efficacité de la politique de ciblage d’inflation. Pour ce faire, nous avons étudié l’effet d’intervention de ce régime sur la dynamique d’inflation. Nous avons recours à la théorie spectrale évolutive afin de modéliser la série de l’inflation dans le but de tester son évolution. Les résultats sont en faveur de l’efficacité de ciblage d’inflation. Le dernier axe de cette thèse s’intéresse à la question de la performance économique de ce régime monétaire. Pour ce faire nous développons une méthodologie originale évaluée selon une approche économétrique originale. En effet, nous qualifions le ciblage d’inflation comme économiquement performant s’il génère une stabilité de l’environnement de la politique monétaire. Le fondement de cette idée fera l’objet du quatrième chapitre. Quant au chapitre cinq, il développera l’approche économétrique basée sur la théorie co-spectrale pour mesure le degré de stabilité de cet environnement. Les résultats montrent que le ciblage d’inflation est économiquement performant. / The inflation targeting policy (ITP) was born after the failure of many monetary policies. However, the ITP was adopted without inherent theory which raised many discussions. In this dissertation, we study the most important debates. In the first chapter, we defined the ITP. Then, we treat the question of the optimal rule conduct. We show that the optimal monetary rule is a type Taylor rule under a Forward-Looking version and which can be linear or nonlinear. In the third chapter, we focus on the discussion about the relevance of the inflation targeting policy. To study this point we use the evolutionary spectral analysis to model the inflation series and we test then, if the ITP cause a structural break. Our results show the relevance of the ITP. The last discussion in this work is to check the macroeconomic performance of the ITP. The main idea is to consider the ITP as economically efficient when it generates a stable monetary environment. The latter is considered as stable when a long-run equilibrium exists to which the paths of economic variables (inflation rate, interest rate and GDP growth) converge. The convergence of the variables’ paths implies that these variables are more predictable and implies a less uncertainty in the economic environment. To measure the degree of convergence between economic variables, we propose, in this paper, a dynamic time-varying variable presented in the frequency approach named cohesion. This variable is estimated from the evolutionary co-spectral theory. The results show that the ITP is a relevance policy and generate a good performance.

Les perspectives de ciblage de l'inflation dans les pays de l'Union Economique et Monétaire Ouest Africaine (UEMOA) / Prospects of inflation targeting in the West African Economic and Monetary Union (WAEMU) countries

Sall, Abdoul Khadry 08 December 2016 (has links)
La présente thèse porte sur « Les Perspectives de Ciblage de l'Inflation dans les Pays de l'UEMOA » dontl'opportunité pourrait être bien saisie à la suite de la nouvelle réforme institutionnelle de l'UMOA et de laBCEAO. Cette réforme doit s'accompagner d'une stratégie opérationnelle explicite dans la mesure où sesinnovations majeures sont très proches d'une politique de ciblage de l'inflation. Pour cela, nous évaluons lapolitique monétaire de la BCEAO axée en partie sur un régime de change fixe depuis les indépendances.Ainsi, après avoir montré la nécessité pour les Banque Centrale d’ancrer les anticipations inflationnistesdans les pays de l'UEMOA et l'apport potentiel de l'annonce d'un objectif d'inflation dans la maîtrise du tauxd'inflation (Chapitre 1), nous montrons que la politique de change fixe n'a pas été à l'origine des tauxd'inflation relativement contenus dans la l'Union, mais pire, elle procure de mauvaises résultats en termesd'une croissance économique élevée et soutenue (Chapitre 2). En cela, nous recommandons pour l’Unionun cadre de type d’une combinaison d’un régime de change intermédiaire et d’une stratégie de ciblage del’inflation. C’est ainsi qu’une cible d’inflation a été déterminée et, elle apparaît différente aussi bien d’un paysà l’autre que de l’objectif de 2% annoncé par le Comité de Politique Monétaire de la BCEAO (Chapitre 3).Nous terminons en déterminant la règle de ciblage d'inflation, et montrons que la meilleure règle optimaleque les autorités monétaires devraient adopter dans un cadre de ciblage de l'inflation concilie l’ancragenominal et la régulation conjoncturelle (Chapitre 4). / This thesis focuses on evaluating the "Prospects of Inflation Targeting in the WAEMU countries" in the wakeof the new institutional reform followed by the WAMU and the BCEAO. This reform must be accompanied byan explicit operational strategy insofar as its major innovations are very close to a policy of inflation targeting.Accordingly, we assess the impact of monetary policy of the BCEAO that focused on fixed exchange ratesince independence. In this respect, we manifest the inability of the fixed exchange rate policy to anchorinflation expectations in the WAEMU countries and the potential contribution regarding the announcement oftarget in controlling inflation (Chapter 1). In addition, we demonstrate, on the one hand, that the fixedexchange rate policy was not the cause of inflation contained in the WAEMU, and on the other, it providespoor results in terms of high and sustained economic growth (Chapter 2). Consequently, we recommend aframework of combination of an intermediate exchange rate regime and an inflation targeting strategy forWAEMU countries. Hence, an inflation target has been determined and it appears to be different from onecountry to another, against the 2% target announced by the Monetary Policy Committee of the BCEAO(Chapter 3). Finally, we define the inflation targeting rule, and show that the best optimal rule that monetaryauthorities adopt in an inflation targeting framework should ideally, reconciles nominal anchor and economicregulation (Chapter 4).
