EconModel This site, run by William R. Parke of UNC Chapel Hill, lets students
and others run simulations of standard micro and macro models. To run
the simulations, you must first download a Windows program. Currently,
all models have a free 10-day trial period. Below is a list of the
available models. As one can see, they cover a fair amount of
Supply and Demand
Who Pays a Sales Tax?
Demand for Labor
Two Goods - Two Prices
The Classical Model
Simple Keynesian Model
Real Business Cycles
Besides the above, the site also has interesting views of data, such
as the yield curve from the 1950s to today and an animated Phillips
Curve, as well as commentary on current issues.
