A critical analysis of central bank independence and governance in Australia and Bangladesh

This study examines central bank independence and governance (CBIG) in Bangladesh and Australia. It applies a unique index model of Ahsan, Skully and Wickramanayake (2008) to assess their respective legal, political, price stability objectives, exchange rate policies, monetary policy and deficit financing practices, transparency and accountability positions from 1991 to 2008. While the model shows CBIG is much weaker in Bangladesh than in Australia, the Bangladesh Bank’s CBIG shown considerable improvement over the period. These findings suggest that the Government of Bangladesh might learn from Australia’s experience with Reserve Bank of Australia and delegate further power and authority to Bangladesh Bank as well as lessen its political interference.

Central bank independence and governance in the South Asia

This paper constructs the central bank independence and governance (CBIG) index for eight South Asian countries and examines their relationship with inflation. This CBIG index is constructed following the unique model developed by Ahsan, Skully and Wickramanayake (2006). This index consists of total 26 variables; all variables together form the overall index and different sub-sets of these variables construct sub-indices (eg. legal; political; price stability objectives; exchange rate policy; monetary policy and deficit financing; and accountability and transparency).
Several countries have improved their CBIG in last fifteen years. The war torn Afghanistan have established a new central bank act in 2003 which has improved the standard of CBIG in the region. In recent time Nepal has made remarkable improvement in its ranking by allowing improved independence to its central bank. Bangladesh has taken lead in term of gradual CBIG improvement in last fifteen years. Sri Lanka, Indian and Pakistan are three countries always maintained a standard level of CBIG. Bhutan and Maldives showed less improvement among the countries. This paper also examines the statistical relationship between CBIG indices and inflation. The results indicate that there is a positive relationship between CBIG and inflation in the region which in contrary to normal expectation that inflation is one of the robust proxy of actual CBIG.

Water security through scarcity pricing and reverse osmosis: a system dynamics approach

Water supply and demand planning is often conducted independently of social and economic strategies. There are presently no comprehensive life-cycle approaches to modelling urban water balances that incorporate economic feedbacks, such as tariff adjustment, which can in turn create a financing capacity for investment responses to low reservoir levels. This paper addresses this gap, and presents a system dynamics model that augments the usual water utility representation of the physical linkages of water grids, by adding inter-connected feedback loops in tariff structures, demand levels and financing capacity. The model, applied in the south-east Queensland region in Australia, enables simulation of alternatives and analysis of stocks and flows around a grid or portfolio of bulk supplies including an increasing proportion of rain-independent desalination plants. Such rain-independent water production plants complement the rain-dependent sources in the region and can potentially offer indefinite water security at a price. The study also shows how an alternative temporary drought pricing regime not only defers costly bulk supply infrastructure but actually generates greater price stability than traditional pricing approaches. The model has implications for water supply planners seeking to pro-actively plan, justify and finance portfolios of rain-dependent and rain-independent bulk water supply infrastructure. Interestingly, the modelling showed that a temporary drought pricing regime not only lowers the frequency and severity of water insecurity events but also reduces the long-run marginal cost of water supply for the region when compared to traditional reactive planning approaches that focus on restrictions to affect demand in scarcity periods.

The trasition from fixed to floating exchange rate regimes: the case of Brazil

This dissertation evaluates macroeconomic management in Brazil from 1994 to the present, with particular focus on exchange rate policy. It points out that while Brazil's Real Plan succeeded in halting the hyperinflation that had reached more than 2000 percent in 1993, it also caused significant real appreciation of the exchange rate situation that was only made worse by the extremely high interest rates and ensuing bout of severe financial crises in the intemational arena. By the end of 1998, the accumulation of internai and externai imbalances led the authorities to drop foreign exchange controls and allow the currency to float. In spite of some initial scepticism, the flexible rate regime cum inflation target proved to work well. Inflation was kept under control; the current account position improved significantly, real interest rates fell and GDP growth resumed. Thus, while great challenges still lie ahead, the recent successes bestow some optimism on the well functioning of this exchange rate regime. The Brazilian case suggests that successful transition from one foreign exchange system to another, particularly during financial crisis, does not depend only on one variable be it fiscal or monetary. In reality, it depends on whole set of co-ordinated policies aimed at resuming price stability with as little exchange rate and output volatility as possible.

Dois exercícios de política monetária e fiscal com atuação ótima do Banco Central

O objetivo da tese é analisar questões relativas à coordenação entre as políticas monetária e fiscal no Brasil após a adoção do regime de metas de inflação. Utiliza-se de um modelo de metas de inflação para uma economia pequena e aberta para a incorporação um bloco de equações que descrevem a dinâmica das variáveis fiscais. Tendo por base os conceitos de Leeper (1991), ambas as entidades, Banco Central e Tesouro Nacional, podem agir de forma ativa ou passiva, e será este comportamento estratégico que determinará a eficiência da política monetária. Foram estimados os parâmetros que calibram o modelo e feitas as simulações para alguns dos choques que abalaram a economia brasileira nos últimos anos. Os resultados mostraram que nos arranjos em que a autoridade fiscal reage a aumentos de dívida pública com alterações no superávit primário, a trajetória de ajuste das variáveis frente a choques tende a ser, na maioria dos casos, menos volátil propiciando uma atuação mais eficiente do Banco Central. Nestes arranjos, o Banco Central não precisa tomar para si funções que são inerentes ao Tesouro. Também são analisadas as variações no comportamento do Banco Central e do Tesouro Nacional em função de diferentes composições da dívida pública. Os resultados mostram que a estrutura do endividamento público será benéfica, ou não, à condução das políticas monetária e fiscal, dependendo do tipo de choque enfrentado. O primeiro capítulo, introdutório, procura contextualizar o regime de metas de inflação brasileiro e descrever, sucintamente, a evolução da economia brasileira desde sua implantação. No segundo capítulo são analisados os fundamentos teóricos do regime de metas de inflação, sua origem e principais componentes; em seguida, são apresentados, as regras de política fiscal necessárias à estabilidade de preços e o problema da dominância fiscal no âmbito da economia brasileira. O terceiro capítulo apresenta a incorporação do bloco de equações fiscais no modelo de metas de inflação para economia aberta proposto por Svensson (2000), e as estimações e calibrações dos seus parâmetros para a economia brasileira. O quarto capítulo discute as diferentes formas de coordenação entre as autoridades monetária e fiscal e a atuação ótima do Banco Central. O quinto capítulo tem como base a mais eficiente forma de coordenação obtida no capítulo anterior para analisar as mudanças no comportamento da autoridade monetária e fiscal frente a diferentes estruturas de prazos e indexadores da dívida pública que afetam suas elasticidades, juros, inflação e câmbio.

Análise do papel da política macroprudencial e sua inserção em um modelo DSGE

Este estudo tem dois objetivos principais. O primeiro, discutir o propósito da popularização das políticas macroprudenciais no pós-crise – que surgiram como uma das soluções para a complexa relação entre estabilidade de preços e estabilidade financeira – suas vantagens em relação à abordagem anteriormente predominante – as políticas microprudenciais – e formas de interação com a tradicional política monetária. O segundo grande objetivo reproduzir um modelo da geração novo-keynesiana que contempla um sistema bancário e características que permitem replicar a condução de uma política macroprudencial (colaterais, depósitos compulsórios, requerimentos mínimos de capital) a fim de analisar a resposta de variáveis macroeconômicas a mudanças nestes parâmetros.

Taylor rule in Brazil

In this paper, we use the Taylor Rule to characterize empirically the Brazilian monetary policy before and after its major and succesful stabilization plan, Real Plan, launched in 1994. Specifically, we show how the inflation coefficient has changed after the stabilization plan was carried out. This is a natural experiment to test theories surrounding the Taylor Rule in which monetary instability is characterized by an inflation coefficient less than one, whereas monetary stability will have a greater than one coefficient (seeWoodford’s (2003)). Very suprisingly the paper shows that the inflation coefficient has remained less than one even after the stabilization. Our results are quite robust with respect to different samples, lags of variables, proxies for GDP, proxies for potential GDP and even with respect to econometric methods (see Bueno (2005a, 2005b)). The implications are very important both theoretically and empirically. First, it shows some gap in theory that deserves further investigation. Second, it suggests that the inflation targeting regime has been uneffective in Brazil confirming a feeling largerly spread among Brazilians.

A crise financeira e a política monetária no Brasil

A crise financeira iniciada em 2007 gerou uma grande recessão nos Estados Unidos e abalou a economia global com consequências nefastas para o crescimento e a taxa de desemprego em vários países. Os principais Bancos Centrais do mundo passaram a dar maior importância para políticas que garantam a estabilidade financeira. É consensual a necessidade de avanços regulatórios e de medidas prudenciais capazes de reduzir os riscos financeiros, mas existem divergências quanto ao uso da taxa básica de juros, não só como um instrumento necessário para garantir a estabilidade de preços, como também para garantir a estabilidade financeira e evitar a formação de bolhas. O Brasil viveu nos últimos vinte anos um período de grande expansão do mercado de crédito, fruto das estabilidades econômica e financeira. O Banco Central do Brasil teve atuação exitosa durante a crise e demonstrou habilidade em utilizar instrumentos de política monetária e medidas macroprudenciais de forma complementar. Nos últimos quatro anos, as condições macroeconômicas se deterioraram e o Brasil atravessou um período de crescimento baixo, inflação próxima ao teto da meta e aumento do endividamento. Enquanto as políticas macroprudenciais foram capazes de evitar a formação de bolhas, as políticas fiscal e monetária foram demasiadamente expansionistas. Neste período houve um enfraquecimento na função-reação do Banco Central, que deixou de respeitar o princípio de Taylor.
