EconSimT is an application, a fully compiled *.exe for MS-Windows 98 and
above.
EconSimT is also an Application Framework, you can write your own firms,
consumers, banks etc, load them dynamically and have them interact. You
introduce them to each other using, the built in, and extendable EconScriptT
scripting language. Such extensions can then be built on by others, you just
distribute the ".class" files your java compiler has produced. In principle
this process is more productive than neo-classical analysis, there being so
much virgin territory to colonise. Start writing a book or training course
today! Its a great way to learn.
