Interactive Tutorials in Principles (General)
Classic economic models is a set of economic models that run through a web browser, some of which are available as free trials. The models are divided into micro and macro models, covering topics such as perfect competition, Keynsian models, price discrimination and utility-based valuation of risk. The models take the form of model link files which can be read by the EconModel plug-in. Access to the non-free models requires an annual subscription, currently 20 USD for a year. Most of the models have exercise sheets in PDF suitable for printing.
