The Global Ecosystem Dynamics Initiative (GED) seeks to describe, analyze, and understand how economic ecosystems work around the world. We focus particular attention on understanding and supporting collaboration within innovation-oriented entrepreneurial ecosystems as a vehicle for promoting the social and economic wellbeing of local and regional economies. GED is affiliated with the MIT D-Lab Local Innovation Group, at the Massachusetts Institute of Technology. GED is founded and advised by an international team of researchers based in Latin America, USA and Europe. Using the TE-SER model of economic ecosystems and Complex Network Analysis, we create maps of collaboration within each ecosystem we study. These maps identify actors who fulfill each of the six key ecosystem support roles identified by the TE-SER model and describe how these actors collaborate to create value for the ecosystem.
