Agent-based models move into the economic mainstream In the 1980s and ’90s, SFI played laboratory to a promising new method known as agent-based modeling. In ensuing decades, agent-based models (ABMs) proliferated across many fields, including economics...

What if one model could realistically predict the economy of an entire country? The entire world? A month-long working group, co-organized by SFI External Professor @doynefarmer.bsky.social, made the case that agent-based models may bring this vision to life:
