Interactive economics laboratory
From the real world
to economic reasoning.
An interactive economics laboratory for models, policy simulation, evidence and cross-school economic experimentation.
Live League directory
A city-level view of the participating network. Every plotted point comes from an approved school identity and a verified city key—never from AI inference or a guessed campus address.
Worldwide distribution of participating League schools
104 schools are plotted at the centres of 38 cities. No national borders or campus addresses are shown.

Persistent World
World Economy remains livePlatform thesis
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.

Make assumptions visible, then trace the mechanism that connects them to outcomes.
Enter systemWorld · Oil Shock · Sandbox
Run a persistent world, test a historical counterfactual or change a controlled teaching model in real time.
Enter systemEvidence Lab
Test claims with curated sources, methods and clearly stated limits.
Enter systemTeams · Countries · Decisions
Connect schools through one persistent fictional world economy.
Enter systemReal World
Daily Brief connects reviewed public economic developments to the tools used to investigate them. Cases make a decision, its constraints and its consequences visible.

Featured case
Balance preparation, stockouts, waste, customer experience and risk in a transparent perishable-inventory decision.
Models & Simulation
Thirty-five focused models make the connection between assumption, equation, curve and interpretation inspectable.
Supply, demand, tax, elasticity and price controls.

ExplorePolicy transmission
Explore a policy mechanism, trace delayed effects into indicators and compare distributional consequences. These are transparent educational scenarios—not forecasts.
Evidence Lab
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
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
Read a real-world development or open a structured case.
State the simplifying assumptions and identify the mechanism.
Adjust controlled variables in an interactive teaching environment.
Use evidence, counterarguments and limitations to challenge the result.
Compare distributional effects, trade-offs and unintended consequences.
Explain what you would do—and what the model cannot decide for you.
