A note from the author

Each Model Link starts an EconModel application. EconModel is a program that explains and simulates economic models.

The process is familiar to most people. When you click on a link to the file 'paper.pdf,' your browser hands the pdf file to Adobe Reader. When you click on a Model Link (for example, the file 'classic.em0'), your browser hands the em0 file to EconModel. What is a Model Link? has some screenshots that explain this process in more detail.

EconModel applications typically include two types of material:

• Model Building.  The core of each presentation is an emulation of a typical chalkboard presentation of the model.
   
• Policy Analysis.  The user can change variables and parameters to study policy changes. This helps in understanding the properties and economic implications of the model.

To activate the model links for Classic Economic Models, you need to download and install the EconModel program.  The right-hand column of this page explains that process.

You also need to subscribe. A one-year $20 subscription provides access to the entire collection of models. Volume discounts apply at 10 or 25 subscriptions. Site licences are available.

Once you have subscribed (and received your ticket class and number), click on any Model Link to register. You can also click on Register (Step 3 to the right). After you register, Step 3: Register shows your subscription expiration date.

The EconModel web site has been online since September 21, 1996. It is listed by Resources for Economists of the American Economic Association, Economics Network of the Higher Education Academy (U.K.), and The Educational Software Cooperative.  EconModel sponsors The Economics Roundtable.
