How economies are highly interdependent

I found the article below while looking through papers on newspapermap.com. It is about how Brazil's recession is affecting Argentina's economic growth. It also details how some other injections into the circular flow will help Argentine growth in 2017.

The key here is that exports are an injection into the circular flow, but depend on foreign income, not domestic income. Therefore as Brazil suffers its 'worse recession in 100 years' their major trading partner suffers a fall in Aggregate Demand too.

This article lends itself to AD/AS analysis and discussion of multipliers. It could be taken to be an article on international trade, but for me would be best suited to a macro IA that discusses how changes in injections have a multiplier effect and to discuss the impact on the economy, government, taxpayers etc.
