Interconnectivity: the new structure of the world economy | Min Zhu | TED Institute

Summary

The 2008 financial crisis exposed the interconnectedness of the global economy. The IMF's research reveals countries' economic positions are now defined by strength rather than size. The world is divided into clusters based on services, manufacturing, and energy. Economic activities are centered around hubs like the US and China. The crisis showed how a collapse in one financial center can quickly affect the entire system, emphasizing the need for global cooperation and vigilance to prevent future crises.
