A relação entre o saldo externo dos EUA e da China: uma análise do desequilibrio macroeconômico nos primeiros anos do século XXI

Abstract

This dissertation was a study of the global imbalances that occurred in the first years of twenty-first century. The analysis encompasses the two biggest countries in the world: USA and China. Many authors are defending that the relationship between the current account of these two countries was one important cause of the subprime crisis. While USA has increased its deficit in the last decade, China has improved its surplus. To investigate this relationship, this study used exogeneity tests. Moreover this dissertation used causality Granger tests in approach of Toda-Yamamoto. The results showed that there is a real causal relationship between USA and China external balance. Furthermore the global imbalances between these two countries contributed to the subprime crisis, because in the tests were detected structural breaks for the external balance of American and Chinese in 2008. The dynamics of the Chinese external balances changed after the subprime crisis.
