EconSim makes economics click.

What EconSim is

EconSim is a free, browser-based catalogue of interactive economics simulations for self-learners and classrooms. Each simulation lets you change the inputs and watch the outcomes respond in real time, so core ideas in micro, macro, finance, game theory, and behavioral economics become tangible. There is no account to create and nothing to install — open a simulation and start exploring, on your own or live with a class.

Who it’s for

• Students

  Turn abstract high-school and university economics into something you can see and adjust — explore at your own pace, with guided predict-first steps that build intuition.

• Teachers

  Run a simulation live with the whole class in minutes. Students join from any device with a link or code — no accounts, no email, no setup — and you watch the results unfold.

• The curious

  Always wondered how a carbon tax, a minimum wage, or compound interest actually plays out? Open a simulation and find out — free, no sign-up.

What makes it different

• Instant, in-browser play

  Every simulation runs immediately in the browser — nothing to install, no sign-up to start.

• Predict-first pedagogy

  Guided steps ask you to predict before you reveal, so each simulation builds intuition instead of just showing a chart.

• Solo and live-classroom modes

  Single-user simulations for self-study, plus multi-user simulations a teacher can run live with a room full of students.

• Pseudonymous, no student accounts

  Students join sessions without accounts, email, or passwords — their actions stay pseudonymous, so there is no student PII to manage.

• Free

  The catalogue is free to explore for learners and classrooms alike.

What you can explore

The catalogue covers microeconomics, macroeconomics, personal finance, game theory, and behavioral economics. A few places to start:

How teachers use it

Teachers create a live session for a multi-user simulation, share a join link or code with the room, and students join in one tap from any device — no student accounts. The class then works through the activity together and discusses the results. See how it works.

Frequently asked questions

Is EconSim free?

Yes. Exploring the catalogue of simulations is free for both self-learners and classrooms, with no account required to start.

Do students need accounts?

No. Students join a live session with a link or code — no account, email, or password. Their participation stays pseudonymous, so there is no student personal data to manage.

What economics topics are covered?

Simulations span microeconomics, macroeconomics, personal finance, game theory, and behavioral economics — for example supply and demand, monopoly versus competition, externalities and Pigovian taxes, the prisoner’s dilemma, and compound interest.

Can I use EconSim in class?

Yes. Teachers can run multi-user simulations live: create a session, share the join link or code, and students participate from any device while the class watches the results together.

Do I need to install anything?

No. Every simulation runs in the browser on a phone, tablet, or laptop — there is nothing to download or install.

Is EconSim suitable for self-study?

Yes. Single-user simulations include guided, predict-first steps and reflections, so a curious learner can build intuition on their own without a teacher.
