If you are a student, there is no better way to learn to think like an economist than actively working with economic models.
To activate the Model Links, you need to download and install the EconModel program. You also need a subscription, which comes in the form of a ticket class and a ticket number. Right now, you can get a free 10-day trial subscription. If you are interested in a longer-term subscription or would like to support the EconModel project, a one year subscription is $20.
