Persistent World
World Economy remains livePlatform thesis
Economics does not begin with a graph.
It begins with a problem.
EconMind OS starts with the issue in front of a learner: a price change, a resource constraint, a market failure, a policy choice or a strategic decision.
- Observe the situation.Identify the people, institutions, constraints and incentives involved.
- Build a model.Choose a mechanism and name the assumptions that make it useful.
- Run the counterfactual.Change a variable, inspect the pathway and compare possible outcomes.
- Check the evidence.Ask what supports the claim, what is missing and what remains uncertain.

Sandbox, Policy Lab and Integrated Workspace
Explore a policy mechanism, trace delayed effects into indicators and compare distributional consequences. These are transparent educational scenarios—not forecasts.

Evidence Lab
A model is not the real world.
Test it.
Move from theory to a focused question, a curated teaching sample, a method, an evidence claim and its limits. Evidence Lab is deliberately upload-free in this release.

Inter-school League
One connected
economic world.
Teams learn through one persistent fictional economy: countries remain connected, policies take time to work, and decisions create effects beyond one screen.
How EconMind works
Reason from a world, not just a worksheet.
- 01
Observe
Read a real-world development or open a structured case.
- 02
Model
State the simplifying assumptions and identify the mechanism.
- 03
Simulate
Adjust controlled variables in an interactive teaching environment.
- 04
Test
Use evidence, counterarguments and limitations to challenge the result.
- 05
Evaluate
Compare distributional effects, trade-offs and unintended consequences.
- 06
Decide
Explain what you would do—and what the model cannot decide for you.
