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.

What happens after the Central Bank of Brazil increases the target interbank rate by 1%?

In this paper I use Taylor's (2001) model and Vector Auto Regressions to shed some light on the evolution of some key macroeconomic variables after the Central Bank of Brazil, through the COPOM, increases the target interest rate by 1%. From a quantitative perspective, the best estimate from the empírical analysis, obtained with a 1994 : 2 - 2004 : 2 subsample of the data, is that GDP goes through an accumulated decline, over the next four years, around 0.08%. Innovations to interest rates explain around 9.2% of the forecast erro r of GDP.

A descontinuidade em banco comercial privado nacional: um estudo de caso: o COMIND

O objetivo deste estudo busca identificar e descrever fatos indicadores da causa de descontinuidade do Banco Comércio e Indústria de são Paulo S.A. - COMIND. Aos 31 de dezembro de 1974, o COMIND assumira a posição do 6ª maior banco privado do país e, aos 19 de novembro de 1985, transformou-se na maior falência da história bancária brasileira. A descrição delineará o perfil da sua trajetória de existência, enfatizando o período da sua última gestão. Utilizando-se de documentação indireta, tais como relatórios de Comissão de Inquérito, de auditoria e de CPI da câmara, procurou-se a consistência das informações pertinentes ao caso em estudo. Os resultados obtidos propiciaram ordenar os fatos e proceder um cruzamento com causas de falências bancárias ocorridas, preponderantemente, nos E.U.A. As conclusões da pesquisa se basearam nas evidências resultantes de análise comparativa, culminando com o entendimento de que houve uma administração bancária frágil, inepta e centralizadora, além de omissão por parte da auditoria independente.

The macroeconomics of price adjustments under information frictions and menu costs

Esta tese se dedica ao estudo de modelos de fixação de preços e suas implicações macroeconômicas. Nos primeiros dois capítulos analiso modelos em que as decisões das firmas sobre seus preços praticados levam em conta custos de menu e de informação. No Capítulo 1 eu estimo tais modelos empregando estatísticas de variações de preços dos Estados Unidos, e concluo que: os custos de informação são significativamente maiores que os custos de menu; os dados claramente favorecem o modelo em que informações sobre condições agregadas são custosas enquanto que as idiossincráticas têm custo zero. No Capítulo 2 investigo as consequências de choques monetários e anúncios de desinflação usando os modelos previamente estimados. Mostro que o grau de não-neutralidade monetária é maior no modelo em que parte da informação é grátis. O Capítulo 3 é um artigo em conjunto com Carlos Carvalho (PUC-Rio) e Antonella Tutino (Federal Reserve Bank of Dallas). No artigo examinamos um modelo de fixação de preços em que firmas estão sujeitas a uma restrição de fluxo de informação do tipo Shannon. Calibramos o modelo e estudamos funções impulso-resposta a choques idiossincráticos e agregados. Mostramos que as firmas vão preferir processar informações agregadas e idiossincráticas conjuntamente ao invés de investigá-las separadamente. Este tipo de processamento gera ajustes de preços mais frequentes, diminuindo a persistência de efeitos reais causados por choques monetários.

Estimating economic interactions of financial suppliers in Thailand

This paper presents a methodology to estimate and identify different kinds of economic interaction, whenever these interactions can be established in the form of spatial dependence. First, we apply the semi-parametric approach of Chen and Conley (2001) to the estimation of reaction functions. Then, the methodology is applied to the analysis financial providers in Thailand. Based on a sample of financial institutions, we provide an economic framework to test if the actual spatial pattern is compatible with strategic competition (local interactions) or social planning (global interactions). Our estimates suggest that the provision of commercial banks and suppliers credit access is determined by spatial competition, while the Thai Bank of Agriculture and Agricultural Cooperatives is distributed as in a social planner problem.

An exploratory study on how to improve the economy of American Samoa

Deep in the South Pacific region about 2,300 miles southwest of the Hawaiian islands1 lies a United States territory that many Americans have never heard of nor known anything about. However, some famous Americans such as Troy Polamalu of the Pittsburgh Steelers, semi retired professional wrestler Dwayne “The Rock” Johnson, and Hawaii Congresswoman Tulsi Gabbard have genealogical roots there. More importantly, many of the Territory’s sons and daughters have served and lost their lives for the United States flag and the cause of freedom around the world. This place is called American Samoa, a collection of seven islands that if glued together would have a total landmass of approximately 76 square miles, just a tad bigger than the capital city of the United States. According to the United States Census Bureau, there were 55,519 residents of American Samoa in 2010.1 The majority of them are ethnic Samoans, a Polynesian sect that traces its history back to early migrants from Southeast Asia who settled the islands around 1500 B.C.2 3 The climate is warm all year long and the forests along the mountains are ripe with vegetation. The main island is Tutuila with its beautiful and coveted landlocked harbor that was used as a coaling station by the United States naval ships during World War II. In fact, it was the Pago Pago Harbor that diminished the impact of the 2009 Tsunami that devastated the Samoan islands by channeling the waters of the Pacific Ocean towards the end of the harbor instead of flooding many other villages surrounding the Pago Pago Bay area. Lives and property were destroyed near the end of the Harbor but it could have been worse for the entire Bay area. Locally grown foods include coconut, taro, banana, guava, sugar cane, papaya, yam, pineapple, and breadfruit. It is completely surrounded by the Pacific Ocean from which the locals obtain a variety of seafood. There is a popular saying in Samoa that goes, “In Samoa, it is impossible to starve 1 American Samoa Department of Commerce, 2012 Statistical Yearbook, http://www.doc.as/wpcontent/uploads/2011/06/2012-Statistical-Yearbook-1.pdf 2 U.S. Census Bureau News, U.S. Census Bureau Releases 2010 Census Population Counts for American Samoa, http://www.census.gov/2010census/news/releases/operations/cb11-cn177.html (Aug. 24, 2011). 3 3 J. Robert Shaffer, American Samoa: 100 Years Under the United States Flag (Honolulu, Hawaii: Island Heritage Publishing, 2000), 34. 4 because people live off of the land’s and the ocean’s abundant resources.” To the west of American Samoa lies a larger group of four islands that make up the Sovereign State of Samoa, which became independent from New Zealand in 1962. Samoa and American Samoa share the same language, culture, and religion but are divided by government and political systems. The focus of this study will be on American Samoa, which became a United States territory in 1900 when the principal chiefs of Tutuila (the largest island in American Samoa) ceded the islands to the United States.
