Paridade do poder de compra e preços relativos no contexto de câmbio flutuante: evidências para o Brasil - 1999 a 2009 / Purchasing Power Parity and Relative Prices in the Context of Floating Exchange Rate Regime: Evidence from Brazil 1999-2009Rincon, André Costa e Silva 27 April 2011 (has links)
O objetivo desse estudo é avaliar a validade da Teoria da Paridade do Poder de Compra (PPC) no Brasil em sua recente experiência de regime de câmbio flutuante, 1999M01-2009M12. São empreendidas decomposições da taxa de câmbio real de forma a evidenciar o papel da taxa de câmbio nominal, dos preços de bens comercializáveis e não comercializáveis, e preços das exportações e importações. A validade da PPC é diretamente testada através de testes de cointegração. Os resultados apontaram que ambos os setores, dos comercializáveis e não comercializáveis, são relevantes nos desvios da taxa de câmbio real, mas que a fonte de desvios não estacionários da PPC está relacionada ao setor dos não comercializáveis, tendo-se, portanto, evidência favorável à validade da Teoria da PPC para o setor dos comercializáveis no Brasil durante o período. Na relação de cointegração do setor dos comercializáveis, a taxa de câmbio nominal se apresentou fracamente exógena e os índices de preços tiveram velocidades de ajustamento significativas, sendo maior para os preços externos. Esses resultados são consistentes com um cenário em que a determinação da taxa de câmbio nominal é dominada por fatores fora do escopo da PPC e os preços dos comercializáveis se ajustam à relação de equilíbrio. / The aim of this study is to evaluate the validity of the Purchasing Power Parity Theory (PPP) in Brazil during its recent experience of floating exchange rate regime, 1999M01- 2009M12. Real exchange rate decompositions are undertaken in order to highlight the role of nominal exchange rate, prices of tradable goods and relative prices of nontradable goods, and prices of exports and imports. The validity of PPP is directly tested through cointegration tests. The results have shown that both sectors are relevant for the deviations of the real exchange rate, but that the source of non-stationary deviations from PPP is related to the nontradable sector, and, therefore, there was favorable evidence for the validity of PPP theory for tradable goods sector in Brazil between 1999 and 2009. For the cointegration relationship of the tradable sector, the nominal exchange rate appeared to be weakly exogenous and the index prices presented significant speeds of adjustment, which was higher for foreign prices. These results are consistent with a scenario in which the nominal exchange rate determination is dominated by factors outside the scope of the PPP and the prices of tradable goods adjusts to the equilibrium relationship.

[en] CHARACTERISTICS OF THE BRAZILIAN FLOATING EXCHANGE / [pt] ESTUDO DA FLUTUABILIDADE DO CÂMBIO BRASILEIROJOAO PAULO DA FONSECA PARRACHO SANTANNA 15 January 2004 (has links)
[pt] Esta dissertação tenta encontrar relações entre as
variações das reservas internacionais do país e da sua
taxa de câmbio. Estas relações são investigadas em
diferentes contextos macroeconômicos, caracterizados
essencialmente por mais duas variáveis: taxa de juros
interna e remuneração do C-bond. Concentramos a análise em
situações em que prevalece, nominalmente, câmbio flexível.
Para isto, analisamos dados da economia brasileira após a
mudança da política cambial de janeiro de 1999. A análise
tem fundamentação teórica no Princípio da Paridade da Taxa
de Juros, conforme aplicado à caracterização da situação
de crise cambial por Carneiro e Wu (2001). Estudamos,
também, a hipótese do Medo da Flutuação, proposta por
Calvo e Reinhart (2000). O estudo foi baseado na análise
de séries de dados mensais e diários. Analisando a série
de dados diários, foi possível identificar correlações
parciais negativas da variação de reservas com a variação
da taxa de câmbio e com a remuneração do C-bond e positiva
com a taxa de juros interna. / [en] This work searches relations between the variation of
Brazilian international reserves and rate of exchange.
These relations are investigated in different macroeconomic
contexts, characterized essentially by two more variables:
the internal rate of interest and the yield of the C-Bond.
Analysis is focused on situations where floating exchange
prevails. That is why we analyze Brazilian economic data
after the change in the Brazilian exchange regimen, in
January of 1999. This analysis has a theoretical basis on
the principle of uncovered parity of the rate of interest,
as well as on the results of Carneiro and Wu (2001) on the
characterization of crisis in the exchange market. We
consider also the hypothesis of fear of floating, proposed
by Calvo and Reinhart (2000). The empirical study is based
on the analysis of series of daily and mensal data.
Analyszing the daily data series, we were able to identify
a negative partial correlation of the reserves variation
with the variation of the exchange rate as well as with the
remuneration of the C-Bond and a positive partial
correlation with the internal rate of interest.

The Taylor Rule ¢w Research of Monetary Policy: A Case for Asia Pacific CountriesSheng, Yao-Ping 21 July 2011 (has links)
This paper investigates whether the ¡§Taylor rule¡¨ can appropriately describe the Central Bank¡¥s monetary policy in Asia-Pacific countries. The countries under
consideration were export-oriented countries that adopted floating exchange rate system, and affected by the Asian financial crisis. They include Taiwan, Korea,
Philippines, Thailand, Indonesia, Japan, Singapore. In addition we divide the sample period into two sub period based on the mid-1997 outbreak of the Asian financial crisis, to check the robustness of our results from the whole period. Furthermore, we investigate that the central bank cares for the quarterly inflation, or annual inflation.
The results over the whole period showed that the Taylor rule describe Central Bank¡¥s monetary policy except for Thailand, Japan and Singapore. The Taylor rule can not describe Japan's monetary policy when the period before Asian financial crisis is adopted. Besides, in addition to Thailand, the central banks concerned quarterly inflation rates than annual inflation rates.

The Open Economy: An Algebraic ApproachPistorelli, Bernardo 01 January 2014 (has links)
In undergraduate international economics coursework students are often exposed to the IS-LM-BP model via diagrammatic analysis. The model itself presents the intuitive mechanics behind how an open economy functions and is generally regarded as useful to policy makers. The goal of this paper is to present an in-depth investigation of the IS-LM-BP model through algebraically representing its components. Our model features a two-country framework with sticky prices and flexible exchange rates. We display some interesting relations between factors that must hold in order for monetary and fiscal policy to be effective. Additionally, a peak at a possible extension to the model is presented in the last section.

More on Monetary Policy in a Small Open Economy with Imperfect International Capital mobility: A Credit View / 信用市場、資本不完全移動與浮動匯率之分析蔡志堅, Tsai, Chih-Chien Unknown Date (has links)
A considerable body of theoretical and empirical literature has evaluated the credit channel of monetary transmission. This paper sets up an open-economy model under floating exchange rates with imperfect international capital mobility based on the Bernanke and Blinder model (1988). Employing our model, we show that a change in money supply has different impacts on the economy in many cases compared to the previous literature. The exchange rate puzzle may occur and when the exchange rate puzzle appears, the Fleming proposition is violated. Besides, by means of a cointegration analysis, we empirically verify the particular case of the exchange rate puzzle with the monthly data from May 1984 to January 2005 in Taiwan. Therefore, our empirical evidences can be matched with our theoretical derivations successfully.

附錄1. 94
附錄2. 103 / Both the system and structure of Chinese economy have been changed rapidly since the launch of "economic reform and opening
to the outside" in Mainland China, and the economic interaction and trade interdependence between Taiwan and Mainland China are intenser and closer. Effective policy analysis models for Chinese economy is very important to the policy makers and policy analysis researcher both in Taiwan and Mainland China. The Computable General Equilibrium (CGE) model has become one of the most important economic policy analysis model because of its characteristic of higher flexibility on benchmark data and structure. The purpose of this study is to review, investigate and analyze the developmental background, developmental progress, modeling procedure, policy simulations and research results.
The brief contents and procedure of this study consist of (1) reviewing on the development of economic research in mainland China and CGE modeling for Chinese economy, (2) reviewing on the literature of CGE models for Chinese economy used on Policy Analysis(1978-1998), (3) reviewing on the development, basic structure, benchmark data and modeling of CGE model, (4) constructing two Chinese Social Accounting Matrix (SAM) tables developed from the most recent 1995 Chinese Input-Output table to be the benchmark data of two CGE models, the "Chinese Economic-Environmental CGE model" and the "Chinese Financial CGE model", which are developed from Chinese government and researchers, and we revise them in this study,(5) applying those two models to show and illustrate the modeling procedure and results of policy simulations of CGE models for Chinese economy.
In conclusion and contribution, it is composed of three parts. (1) The development of CGE model in Mainland China can be divided into two ages, "The Beginning"(1978-1991) and "The Take-off"(1992-), which results from the development of economic research in Mainland China, the rapidly changed economic system and structure of Chinese economy, and government's urgent demands for policy-analysis tools. (2) The literature of CGE models for Chinese economy used on policy analysis from 1978 to 1998 can be classified into seven groups- trade policy, energy and environmental policies, public finance and tax reform policies, economic reform and development strategy, external shocks, monetary and financial policies, and social insurance policy.
(3) We apply those two CGE models for Chinese economy to analyze the economic and environmental impacts of environmental policy- " Green-Oriented Energy Policy"(2000-2015) and the economic impacts of the " Managed Floating Exchange Rate Policy"(1998).

Exchanging Approaches: Evaluating Methods to Counter Chinese Currency UndervaluationTrask, Brandon Marshall 28 November 2013 (has links)
I evaluate four possible approaches the United States may take to address China's practice of undervaluing the renminbi: 1) a challenge under Article XV of the GATT and the associated IMF provisions; 2) countervailing duties; 3) antidumping measures; and 4) safeguard measures. I conclude that the first three approaches are unlikely to succeed; there are a number of legal and political obstacles to the pursuit of these remedies. While the current WTO safeguards regime is likely insufficient, a new safeguards regime can--and should--be developed. I review and critique Dani Rodrik's proposal for a new safeguards regime and set out my own basic blueprint for a significantly expanded safeguards regime, emphasizing that flexibility in the realm of international trade law would help to secure overall stability in international trade itself. In order to be effective shock absorbers, safeguards must become far more flexible.
