Última Alternativas de políticas comerciais para o agronegócio brasileiro sob diferentes pressuposições de retorno à escala AgEcon Gurgel, Angelo Costa; Campos, Antonio Carvalho. Este trabalho procura determinar os impactos de diferentes opções de política comercial, sob pressuposições alternativas de retornos à escala e natureza da competição, nos segmentos industriais, com ênfase especial nas indústrias ligadas ao agronegócio. O modelo de equilíbrio geral aplicado, GTAPinGAMS, é usado para implementar as simulações. Os resultados sugerem que os ganhos de bem-estar tenham sido superiores no modelo que considera as imperfeições de mercado. As variações setoriais na produção, importações e exportações foram levemente diferentes em magnitudes e sinais, sob pressuposições alternativas de estruturas de mercados, e dependentes da política comercial implementada. As diferentes medidas de política comercial permitem o aproveitamento de...

O objetivo deste trabalho é analisar os efeitos de longo e curto prazos de choques na taxa de câmbio real sobre o saldo da balança comercial agropecuária brasileira. O procedimento metodológico empregado foi a análise multivariada descrita em Johansen (1988 e 1991) apud Hamilton (1994). Os resultados indicam que existe uma relação de longo prazo entre a depreciação na taxa de câmbio real e o saldo da balança comercial. Verifica-se que, no longo prazo, um aumento de 1,0 % da taxa de câmbio leva a uma expansão de 2,10 % no saldo da balança comercial. Esse resultado está consistente com a condição de Marshall-Lerner que afirma: no longo prazo, o efeito volume deve superar o efeito preço, promovendo, assim, um aumento no saldo da balança comercial. Entretanto,...

The Brazilian pork exports have been affected by several shocks on the 2000s. This paper aimed to analyze these shocks. The focus of this papers are the main international shocks on the last years: the international economics crisis and de influenza A (H1N1). Analyses were made over the main Brazilian pork exports destinations: Russia and Hong Kong. The theory of international trade was used as a theoretical framework and analysis of intervention provided methodological support. The results show that the quantum exported to Russia has not been affected by the recent shocks. However the prices was negatively affected by crisis in the short term. The quantum exported and the exports prices to Hong Kong have been negatively affected by crisis in the short...

Ano: 2006 URL: http://purl.umn.edu/55177 Áreas monetárias ótimas: desenvolvimentos recentes e perspectivas para os países do MERCOSUL AgEcon Coronel, Daniel Arruda; Amorim, Airton Lopes; Campos, Antonio Carvalho. This paper consists of a review of the most important contributions to the understanding of the Optimum Currency Areas (OMA) and on the perspective of implementing such a policy measure into Mercosur. The theoretical support was obtained from reference studies on the European common currency which established the guidelines for the creation of the Euro zone. The findings on the literature review point out that a successful process of macroeconomic coordination is crucial for the implementation of a common currency area. Therefore, before engaging in a process of establishing a common currency area, Mercosur´s members must adopt supranational macroeconomic policy measures that would align their economies to reach stabilization in a regional context.

Ano: 2010 URL: http://purl.umn.edu/58670 Transmissão de preços entre mercados regionais de carne de frango no Brasil AgEcon Mattos, Leonardo Bornacki de; Lirio, Viviani Silva; Lima, Joao Eustaquio de; Campos, Antonio Carvalho. Non-negligible transaction costs restrict the transmission of price shock between markets. The aim of this work was to analyze the effects of transaction costs on the spatial integration of the internal market for chicken meat, from 1998 to 2007. The applied methodology was based on the Threshold Cointegration Analysis. The results indicate the presence of significant barriers to the price transmission between the markets, existing probably due to the transaction costs. Prices are not very sensitive to eventual deviations of the long run equilibrium. It could also be noted that a relatively long period is necessary to eliminate price shocks, and the price transmission process is asymmetric.

Ano: 2010 URL: http://purl.umn.edu/94798 Transmissão de preços no mercado internacional de café robusta AgEcon Cunha, Denis Antonio da; Braga, Marcelo Jose; Campos, Antonio Carvalho; Fernandes, Luciany Lima. The robusta coffee market has experienced changes which are characterized by a growth in the demand and the confirmation of Vietnam as the world’s greater producer and exporter leaving behind traditional producers as Indonesia. These changes motivated the analysis of international price integration and the main markets of this commodity: Vietnam, Brazil, Indonesia and India. It was tested the hypothesis that Vietnam transmits prices shocks to the other markets. The framework used the analysis of co-integration and the Vector Error Correction (VEC) model. It was shown that, in the period from 1988 to 2005, the foreign price and the ones from Vietnam, Brazil and Indonesia were integrated and the India’s price was affected by factors that are not common to...

The objective of this paper was to verify the market power of the Argentinean, Brazilian and American exports of soymeal to the European Union, the main consumer market of this commodity. For that, the article is based on the methodology of residual demand. Using the methods Seemingly Unrelated Regression (SUR), Two-Stage Least Squares (2SLS) and Three-Stage Least Squares (3SLS), the results indicated that, though this segment is concentrated by Argentina, Brazil and the United States, none of these countries presented market power for soymeal exports. In other words, they are not able to change soymeal prices without to decrease the exports Tipo: Working or Discussion Paper Palavras-chave: Market Power; International Trade; Soymeal; Residual Demand; Industrial Organization; International Relations/Trade; F12; L13. Ano: 2010 URL: http://purl.umn.edu/114462 Impactos da influenza aviária no mercado internacional de carnes AgEcon Valente, Luiza Carneiro Mareti; Gomes, Marilia Fernandes Maciel; Campos, Antonio Carvalho. Animal infectious disease outbreaks as Avian Influenza, Foot and mouth disease and Bovine Spongiform Encephalopathy can influence trade and bring economic consequences to affected countries. For this reason, this work aims to analyze the effects on meat import demand in the years of 1997 and 2003 to 2005, the Avian Influenza outbreaks period. The analytical framework used was panel data econometrics. The results point to a reduction on chicken meat demand in 1997 and increase to the other meats, indicating a possible substitution. From 2003 on, chicken meat demand showed slight increase, as did pig meat, only bovine meat demand showed a reduction. This fact can be explained by a restriction on bovine and chicken supply caused by the imposition of sanitary...

Ano: 2009 URL: http://purl.umn.edu/94837 O Brasil na ALCA: avaliação dos efeitos de duas propostas de adesão AgEcon Lirio, Viviani Silva; Campos, Antonio Carvalho. This study has the objective of evaluating the economic effects of the Brazilian integration into the Free Trade Association of Americas - FTAA under two alternative scenarios. In the first, the adhesion of the Brazilian economy would happen as an isolated country. In the second, the joint adhesion of Brazil would follow the rules established for all members of MERCOSUR. The analytical framework is that of an applied general equilibrium analysis which permit the measurement of different impacts of simulations on selected economic indicators. The results point out that the joint adhesion of MERCOSUR countries as an economic block into FTAA, which is the position defended by Brazilian negotiators, is much more beneficial to the Brazilian economy than the...

This study analyzed the Brazilian coffee exporter’s losses between the years 2002 and 2009, by emphasizing the 2007/09 crisis, which affected several sectors and generated instability and uncertainty about the future results of the economic activities. The Brazilian coffee exporting sector is fully inserted in this context, once it acts in the financial markets and it is still subject to the strong variations from the physical market. Thus, the central analysis dealt with the volatility of the exporters returns and was based on auto regressive models with conditional heteroscedaticity (ARCH) and on the Value at Risk (VAR) estimative. As a supplement, the effects from the external demand for the Brazilian coffee and from the exchange rate variation over the...

The present work looked for to show the influence of nominal variable in the determination of nominal exchange rate R$/USS. For this, the model of the parity of the tax of interests was used, ally to the monetary market. It was looked, also, to foresee the tax of exchange rate R$/USS, until December of 2005. For reaching such objectives, the equations of the system had been obtained by the Vector Error Correction Model (VECM). The results had shown that the nominal variable are very important to determinate the exchange rate and that the model of parity of the tax of interests, ally to the monetary market is confirmed for the Brazilian case in the period of analysis (jan/1999 to dez/2004). This conclusion is made on the basis of the high capacity of... Tipo: Journal Article Palavras-chave: Exchange; Forecast; Brazil; International Relations/Trade.
