Speculative Attacks on Debts and Optimum Currency Area: A Welfare Analysis
No full textResorting to an extension of the debt crisis model of Cole and Kehoe (JIE 1996), we evaluate financial aspects of an optimum currency area. Our focus is to appraise the welfare of a country, which belongs to a monetary union and might suffer a speculative attack on its public debt. A default may be avoided by an inflation tax on common-currency debt, but this decision depends on majority voting and have costs associated with it. Moreover, the model considers symmetry between national and central governments' decisions about inflation and also describes the loss in international bankers' confidence towards one country being passed on to another. One of our results is that, for a country with low weight in the voting system, common-currency regime is superior in terms of expected welfare to dollarization and may be a better choice than the local-currency one, as the central bank under the latter regime undergoes some political influence from its government.
Inflation Targeting in Emerging Market Economies
No full textThis paper assesses inflation targeting in emerging market economies (EMEs), and develops applied prescriptions for the conduct of monetary policy and inflation-targeting design in EMEs. We verify that EMEs have faced more acute trade-offs - higher output and inflation volatility - and worse performance than developed economies. These results stem from more pronounced external shocks, lower credibility, and lower level of development of institutions in these countries. In order to improve their performance, we recommend high levels of transparency and communication with the public and the development of more stable institutions. At an operational level, we propose a procedure that a central bank under inflation targeting can apply and communicate when facing strong supply shocks, and suggest a monitoring structure for an inflation-targeting regime under an IMF program.
As peculiaridades na escrita pianística de Ronaldo Miranda: sugestões interpretativas e técnico-musicais
No full textPretende-se, neste trabalho, estudar a relação entre as obras para piano solo de Ronaldo Miranda, identificar os procedimentos composicionais utilizados pelo compositor e, a partir daí, extrair ferramentas que facilitem uma adequada interpretação musical das mesmas. O objeto deste projeto firma-se na interpretação musical, através das características notacionais da partitura à luz de um olhar analítico e do levantamento das peculiaridades da escrita pianística. Propõe-se que o intérprete tenha um conhecimento prévio dos elementos que são largamente utilizados pelo compositor e considere os exercícios técnicos sugeridos no último capítulo, compostos pelo autor deste trabalho, com base na identificação e recorrência dos padrões pianísticos composicionais de Ronaldo Miranda. Sendo assim, o pianista terá ao seu dispor recursos que fundamentarão uma postura interpretativa mais coesa, considerando o processo cognitivo, a percepção e a atenção dada no preparo para a execução da obraIt is intended to study the relationship between the works for solo piano by Ronaldo Miranda, identifying the compositional procedures used by the composer and, thereafter extracting tools to facilitate a proper musical interpretation thereof. The object of this project is based on the musical interpretation, through the notational characteristics under an analytical view and setting up the peculiarities of the pianistic writing. It is proposed that the interpreter has prior knowledge of the elements that are widely used by the composer and consider the technical exercises suggested in the last chapter, composed by the author of this research, based on the identification and recurrence of pianistic patterns of Ronaldo Miranda. Thus, the pianist will have at his disposal, resources that will build a more cohesive rendition, considering the cognitive process, perception and attention given in preparation for performing the wor
