Effects of central bank independence reforms on inflation in different parts of the world

The purpose of this study is to analyze the effect of CBI-reforms on inflation in different parts of the world from a theoretical and empirical perspective. Compared to previous studies, this study focuses on whether CBI-reforms have different effects on reducing inflation in different parts of the world. The study is based on a 132 country data-set from 1980 to 2005 compiled by Daunfeldt et al. (2008). The result indicates that the reduction in inflation due to the CBI-reforms varies between 2.2 and 12.32 percentage points in Asia, Europe, South America and Oceania, supporting the claim that implementing CBI-reforms can be successful in reducing inflation in most of the parts of the world.

What happens after the central bank of Brazil increases the target interbank rate by 1%?

I start presenting an explicit solution to Taylorís (2001) model, in order to illustrate the link between the target interest rate and the overnight interest rate prevailing in the economy. Next, I use Vector Auto Regressions to shed some light on the evolution of key macroeconomic variables after the Central Bank of Brazil increases the target interest rate by 1%. Point estimates show a four-year accumulated output loss ranging from 0:04% (whole sample, 1980 : 1-2004 : 2; quarterly data) to 0:25% (Post-Real data only) with a Örst-year peak output response between 0:04% and 1:0%; respectively. Prices decline between 2% and 4% in a 4-year horizon. The accumulated output response is found to be between 3:5 and 6 times higher after the Real Plan than when the whole sample is considered. The 95% confidence bands obtained using bias-corrected bootstrap always include the null output response when the whole sample is used, but not when the data is restricted to the Post-Real period. Innovations to interest rates explain between 4:9% (whole sample) and 9:2% (post-Real sample) of the forecast error of GDP.

Economia evolucionária e path dependence do investimento externo japonês: um estudo do Leste Asiático no período pré Segunda Guerra Mundial

A abertura da economia e o reinício das relações econômicas japonesas com o exterior e o processo de industrialização da economia japonesa na Era Meiji levaram o Japão a investir no exterior. Os investimentos japoneses no exterior cresceram preponderantemente no Leste Asiático, concentrando-se nessa área até o término da Segunda Guerra Mundial. A tese mostra que existem restrições de caráter institucional e histórico, que impõem limitações às empresas quanto ao leque de opções para investirem no exterior. Uma vez que as empresas japonesas fizeram a opção, impostas por aquelas restrições, de investir no Leste Asiático, feedbacks positivos, propiciados pelos eventos históricos e institucionais, geraram auto-reforços, levando a um resultado de inflexibilidade - lock-in - para sair dessa região. A tese comprova que explicar os investimentos externos japoneses pelo modelo de economia evolucionária, através do processo de path dependence, que incorpora o caráter institucional e histórico, é mais plausível do que as interpretações convencionais.
