La présente thèse analyse les interactions entre les stratégies de ciblage d’inflation et leur contexte institutionnelau sein des économies émergentes. Plus précisément, les investigations empiriques menées dans le cadre de cettethèse visent à étudier le rôle du cadre institutionnel dans la conduite et l’efficacité de cette stratégie de politiquemonétaire. Pour cela, nous procédons en deux étapes. Dans un premier temps, nous considérons le cadreinstitutionnel comme exogène à l’adoption du ciblage d’inflation et analysons dans quelle mesure ce cadre a pujouer un rôle dans les performances macroéconomiques des pays émergents cibleurs inflation. Ainsi, après avoirposé les bases conceptuelles du ciblage d’inflation et mis en évidence le rôle des pré-requis économiques etinstitutionnels dans le choix des économies émergentes d’adopter cette stratégie de politique monétaire (chapitre1), nous montrons qu’un certain nombre de conditions institutionnelles ont pu renforcer l’efficacité du ciblaged’inflation en termes de stabilité des prix (chapitre 2). Puis, dans un second temps, nous nous plaçons postadoptionet considérons le cadre institutionnel comme endogène à l’adoption du ciblage d’inflation. L’objectifvisé est alors d’analyser la réponse des autorités des économies émergentes à l’adoption de ce cadre de politiquemonétaire. Nous montrons ainsi que l’adoption du ciblage d’inflation exerce un effet disciplinant sur la conduitede la politique budgétaire, en incitant notamment le gouvernement à intensifier ses efforts de mobilisation desrecettes publiques (chapitre 3). Enfin, nous analysons la politique de change des pays émergents cibleursd’inflation et montrons que la poursuite simultanée d’une cible officielle d’inflation et d’une cible implicite dechange peut être contreproductive en termes de performances macroéconomiques, surtout lorsque cette gestiondu change est motivée par des considérations de stabilité financière (chapitre 4). D’où l’importance pour lespays émergents souhaitant adopter une stratégie de ciblage d’inflation de conduire en amont des réformesstructurelles visant à développer leur marché bancaire et financier. / This thesis deals with the interactions between inflation targeting strategies and their institutional framework inemerging economies. More precisely, empirical investigations conducted in this thesis aim to study the role ofthe institutional framework in the conduct and efficiency of inflation targeting. To this end, we proceed in twosteps. First, we consider the institutional framework as exogenous to inflation targeting adoption and analyzewhether this framework has impacted macroeconomic performance of inflation targeting countries. Thus, afterlaying the conceptual background of inflation targeting and showing the importance of economic andinstitutional prerequisites in the choice of emerging countries of adopting this monetary policy strategy (chapter1), we show that some institutional conditions can strengthen the performance of inflation targeting countries interms of inflation level and volatility (chapter 2). Then, in a second step, we consider the institutionalframework as endogenous to inflation targeting and analyze the response of authorities to the adoption of thismonetary policy strategy. The first result that emerges is that the adoption of inflation targeting provides strongincentives to government for improving fiscal discipline, especially the collection of domestic tax revenue(chapter 3). Finally, we analyze the exchange rate policy of inflation targeting emerging economies and showthat the pursuit of two nominal targets, inflation and exchange rate, can be counterproductive in terms ofmacroeconomic performance, more particularly when this exchange rate management is motivated by financialstability considerations (chapitre 4). Hence the importance for inflation targeting candidates of conductingstructural reforms to increase financial development.

Inicialmente, procura-se fazer uma exposição da teoria da Curva de Phillips, partindo da abordagem clássica até a abordagem dos novos keynesianos. A revisão da literatura destaca que a Curva de Phillips tem dificuldade em se ajustar à dinâmica da inflação. Dessa forma, a inclusão do termo que representa a inércia da inflação melhora sua adequação. Conjuntamente, o nível de atividade representado pelo hiato do produto não é estatisticamente significativo, fato esse que é suportado por outros trabalhos na literatura. Avalia-se a utilização do custo unitário do trabalho como proxy do nível de atividade, e os resultados não se alteram significativamente. Os dados de inflação relativos ao último trimes / This dissertation assess the inflation dynamics in Brazil through a hybrid Phillips Curve, at the specification that allows the "forward term", represented by inflation expectation, and the "backward term" through by inertial inflation. Initially, several approaches for the Phillips Curve's theory, from classical to new Keynesian, are presented and detailed. As pointed out by the precedent literature, it is shown that the Phillips Curve has some difficulty in adjusting to the inflation dynamics and, as a consequence, that the addition of the “backward term” enhances its fit. Furthermore, the inclusion of a proxy variable for the level of activity, represented by the output gap, is not statistically significant, result supported by previous studies in literature. Finally, it is analyzed the use of a unit labor cost as a proxy for the level of activity, with no significant changes in the results. The inflation data regarding the last tree months of 2002 are influenced by the effects of the political crisis at t

[pt] Estimamos um modelo DSGE para a economia brasileira abrangendo a transição do regime de bandas cambiais para o regime de metas para a inflação ocorrida em 1999. Utilizamos um modelo novo keynesiano de pequena economia aberta no qual o Banco Central segue uma regra de política monetária estruturalmente distinta em cada regime. Encontramos diferenças significativas na dinâmica macroeconômica e nos mecanismos de transmissão dos choques estruturais, com destaque àqueles relacionados ao setor externo da economia. Realizamos experimentos contrafactuais onde simulamos o impacto de cenários alternativos para a transição de regime na trajetória das variáveis econômicas brasileiras. Entre outros resultados, as simulações sugerem que a manutenção do sistema de bandas cambiais seria insustentável enquanto a antecipação da implementação do regime de metas para a inflação para antes da crise da Rússia de 1998 poderia deixar a economia brasileira em situação mais favorável. Por fim, mostramos que um teste de quebra estrutural aplicado sobre todo o período amostral detecta com precisão a ocorrência da mudança de regime em 1999. / [en] We estimate a DSGE model of the brazilian economy taking into account the transition from the exchange rate band system to inflation targeting occurred in 1999. We use a new Keynesian small open economy model where the Central Bank follows structurally different monetary policy rules in each regime. By comparing the transmission channels of exogenous shocks we find significant differences across the regimes, specially on those shocks related to the foreign sector of the economy.We then perform counterfactual experiments where we simulate the response of key macro variables under alternative scenarios for the regime transition. Among other results our simulations suggest that the continuation of the exchange rate band system could have been unsustainable while anticipating the transition to inflation targeting before the Russian crisis of 1998 could have benefited the economy. Additionally, we show that a structural break test applied to the whole data sample correctly identifies the regime change in 1999.

L’objectif est d’analyser les déterminants et les mécanismes de transmission de la politique monétaire en Chine au cours des deux décennies passées. Elle contribue à la littérature par le biais de deux nouvelles mesures de la politique monétaire en Chine, l'une combinant les instruments utilisés par la banque centrale et l'autre basée sur les discours de la banque centrale sur la politique monétaire. Ces deux approches permettent de prendre en compte le comportement complexe et adaptatif de la banque centrale. Ces mesures permettent de mettre en évidence des changements substantiels dans le style de la politique à partir de 2002, plus graduelle et agressive envers l’inflation, en lien avec le début du mandat du gouverneur Xiaochuan, le processus de libéralisation des taux d’intérêt et l’ouverture commerciale et financière de la Chine. De plus, l’estimation d’un modèle à choix discret révèle une politique monétaire caractérisée par une politique accommodante sur l’inflation avant 2002 et un ciblage implicite de l’inflation à partir de 2002, similaire à celles du G3 pré- et post-1979. Enfin, cette thèse analyse les facteurs expliquant la déformation de la courbe des taux obligataires en Chine au cours de la dernière décennie. Alors que le contrôle des taux d’intérêt peut entraver l’usage de la courbe de taux comme référence pour évaluer les actifs risqués, celle-ci évolue bien en lien avec les autres instruments, la situation macroéconomique en Chine et de plus en plus aux communications de la banque centrale. Enfin, nos analyses révèlent l’influence de la politique monétaire américaine sur celle de la Chine et sur l’évolution de la courbe de taux sur la décennie passée. / The objective of this thesis is to enhance the understanding of the determinants and the transmission mechanisms of monetary policy in China over the last two decades. It contributes to the literature providing two new composite measures of monetary policy in China based on alternative approaches, one combining the large range of monetary policy instruments and the other based on central bank speeches. Both prove to be essential to take into account the complex and adaptive behavior of the People’s Bank of China (PBC). Our instrument-based monetary policy index emphasizes substantial changes in policy style towards smoother but more hawkish policy moves from 2002 onwards, consistent with the start of the mandate of Governor Zhou Xiaochuan, the interest rate liberalization process and the increasing trade and financial opening. Moreover, the estimation of a discrete-choice model implies a conduct of monetary policy characterized by an inflation-accommodating policy before 2002 and an implicit inflation targeting from 2002 onwards, which respectively resembles that of pre-1979 and post-1979 policy of the G3. Our thesis examines the deformation of the bond yield curve over the last decade to evaluate monetary policy transmission mechanisms. While regulated interest rates can hamper the use of the yield curve as benchmark for pricing risk, the latter moves in line with the other instruments, the macroeconomic situation, and increasingly to central bank communication, a crucial step toward a market oriented system. Finally, US monetary policy significantly affects monetary policy determinants and transmission mechanisms in China, particularly from its WTO accession in 2001.

本文建立一個小型開放經濟的內生成長模型，並且以貨幣進入生產函數的方式，將貨幣引入經濟體系。據此，我們分別探討勞動外生及勞動內生的狀況下，央行以釘住通貨膨脹率作為貨幣政策，民眾的信念是否可以造成景氣的波動，並探討央行採行未預料到的貨幣政策及預料到的貨幣政策會如何影響經濟體系相關變數的成長率。 　　根據本文的分析，我們發現在勞動外生的狀況下，通貨膨脹率與Tobin q值呈現負向關係，由此我們可以推論，提高通貨膨脹率目標將對經濟成長率造成負面的影響。當央行採取通貨膨脹率指標作為貨幣政策時，經濟體系呈現均衡的確定性，表示民眾的信念不會造成景氣的波動。若央行調整通貨膨脹率目標時，名目貨幣供給成長率和通貨膨脹率呈現不同比例的變動，且變動方向不確定，需端視實質餘額成長率下降的效果與通貨膨脹率調整的效果何者較大才可決定。在政策宣示的部分，宣告期間的長短僅影響經濟成長率、實質資本成長率及實質貨幣餘額成長率的跳動幅度，不影響動態調整路徑的形狀。 　　在勞動內生化的狀況下，通貨膨脹率增減不影響Tobin q值的變動，故提高通貨膨脹率目標不會影響經濟成長率。當央行採取通貨膨脹率指標作為貨幣政策，勞動需求線斜率大於勞動供給線斜率時，經濟體系呈現均衡的不確定性，表示民眾的信念可以造成景氣的波動在央行調整通貨膨脹率目標時，名目貨幣供給成長率和通貨膨脹率呈現同方向、同比例變動。最後，政策宣示部分，政策宣告期間的長短會造成經濟成長率、實質資本成長率及實質貨幣餘額成長率呈現不同的動態調整路徑。

This study examines the development of monetary theory and various policy frameworks as implemented at the time of writing. The aim of the study was to determine the effect of monetary policy on disintermediation and re–intermediation throughout the periods of the various monetary policy frameworks in South Africa, specifically between 1970 and 2010. In order to achieve the research objective given above, a review was firstly conducted of the literature on monetary theory and policy. This literature review gave attention to the various methods of evaluating the extent of disintermediation, elaborating on the various factors that influence the disintermediation process. The literature suggests that the occurrence of disintermediation can be determined by comparing income velocity data to real interest rate data. The second step in achieving the research objective was to examine the South African income velocity data in comparison to the South African real interest rate data over the period 1970 to 2010. The study found that disintermediation arises from the application of semi–direct or direct monetary controls, which in turn creates abnormal interest rate gaps. Despite the different monetary frameworks adopted in South Africa from 1970 to 2010, a uniform response can be noted. It is observed that whenever real interest rates trough, income velocity in turn peaks, indicating disintermediation. The opposite is true for a high real interest rate environment; income velocity declines, indicating re–intermediation, as returns are sought for in the banking sector. It is also observed that monetary policy implementation proves difficult owing to its forward–looking nature. Complications arise out of the elasticity of transmission mechanisms, the lag effect thereof and models that are backward looking based on historical data. In short, the study found that care should be taken by monetary authorities not to over–act in either direction, whether monetary tightening or easing. / Thesis (M.Com.

How should central banks react to movements in the exchange rate? Can social welfare be improved if the policy maker is giving explicit or implicit consideration to fluctuations in the exchange rate? These are some of the principal questions addressed in this thesis, which analyzes the influence of exchange rates on prices and monetary policy, from an empirical as well as a theoretical perspective. The thesis consists of four self-contained papers, and sets off by providing some empirical evidence for incomplete exchange rate pass-through. Incomplete exchange rate pass-through is subsequently incorporated into a theoretical model of a small open economy, to study how exchange rate fluctuations affect monetary policy. The first chapter is an empirical paper studying the relation between exchange rates and prices, using data on Swedish exports of automobiles and kraft paper. A price determining error correction model indicates results consistent with price discrimination and incomplete exchange rate pass-through. In the second chapter, a small open economy aggregate supply-aggregate demand model, allowing for incomplete exchange rate pass-through, is developed to analyze the effects of limited pass-through on monetary policy. The results suggest that the optimal policy reaction, both to foreign and domestic shocks, is dependent on the degree of exchange rate pass-through. The third chapter studies what the delegated monetary policy should be in an open economy with limited pass-through. In particular, the question of whether to delegate an exchange rate-stabilization objective to the policy maker is investigated. The results show that incorporation of an explicit nominal, or real, exchange-rate term in the (optimized) objective function only improves social welfare marginally. The fourth chapter assumes, in contrast, that monetary policy is implemented through a simple instrument rule. It is examined whether the policy maker’s performance, in terms of social welfare, can be improved by also responding to the exchange rate. The results indicate that the exchange rate-augmented policy rules do not outperform an optimized rule without the exchange rate, irrespective of the degree of pass-through. Social welfare is, however, improved by an indirect exchange rate response, which is reached using a policy rule based on Consumer Price Index (CPI) inflation, rather than on domestic inflation. / Diss.
