The Integrated Economy

When Models Collide — Cross-Model Complexity Economics Simulation

Real economies are not just stock markets, not just supply chains, not just ecosystems of competing firms. They are all of these at once, woven together into a fabric where a supply chain disruption can trigger a market crash, which cascades through a dependency network, and where organizational rigidity determines which firms adapt and which ones die. This simulation links four foundational models from complexity economics into a single coherent system.

Integration Insight

In isolation, each model produces its own emergent phenomena. When linked together, new dynamics appear that none of the individual models can generate alone: supply chain shocks amplify through financial contagion, technology disruptions trigger cascading firm failures, and organizational flexibility becomes the key determinant of systemic resilience. The economy's response to crisis is path-dependent and non-linear, just like real macroeconomic dynamics.

Simulation NORMAL Tick: 0 / 500

Scenario

Baseline: GDP remarkably stable (std dev 0.053). Market index declines from ~97 to ~21 as prices converge to fundamentals. Gini rises steadily to 0.70. Flexibility drifts to floor of 0.20 -- peacetime rigidity.
