Abstract

This paper uses time varying graphs to evaluate the Brazilian production structures, assessing the relationship across economic sectors overtime given important macroeconomic shocks in the country. We use the annual Brazilian input-output matrices from the World Input–Output Database for the period 1995–2011. Our results show possible positive impacts of macroeconomic policies and higher commodity prices on increased network connectivity between 2002 and 2003, the negative influence of the 2008 crisis resulting in decreased network connectivity, and the intensification of the connectivity of the food, petrochemical and metals, and machinery sectors. These results provide insights on how potential macroeconomic exogenous shocks and policies propagates through the national production structure.

用动态时变图评估巴西的生产结构

本文利用时变图评估巴西的生产结构，在巴西宏观经济受到重要冲击的情况下，评估各经济部门加班时间的关系。我们使用了世界投入产出数据库中 1995-2011 年期间的巴西年度投入产出矩阵。我们的研究结果表明，宏观经济政策和商品价格上涨可能对 2002 年至 2003 年间网络连通性的提高产生积极影响，2008 年危机的负面影响导致网络连通性下降，食品、石化和金属以及机械行业的连通性增强。这些结果为了解潜在的宏观经济外生冲击和政策如何通过国家生产结构传播提供了启示。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
