|Introduction to ECF program||2006-10-17|
The ECF (Economic Circular Flows) program allows users to build their own economic models in an interactive manner. Nodes and flows are added by mouse clicks and connected to one another by dragging connector symbols. The magnitude of some flows have to be prescribed, while the other flows are calculated.
This issue of the program is version 184.108.40.206. Some pictures in this manual may not show the latest program version but the functions are the same. The latest features of the current version are not documented at all (sorry).
The version 220.127.116.11 can:
Future versions will have more features until the whole theory of static and dynamic models is covered. See contents parts 1 and 2. Some mayor improvements will be:
Anyone who is interested is invited to contribute to the development.
Java Plug-in and ECF program
The easiest way of running the ECF program is to first install a Java Plug-in. Java Plug-in allows you to run any executable jar-file by a double mouse click. (If you already have a Java plug-in on your system, then you do not have to do this once more.) The start page http://java.com/en/index.jsp will lead you to automatic download if you press the Free Download button.
Then download the ECF executable jar-file by clicking this link ECF.jar . Save the file on your computer. Newer Windows versions (Windows 2000) change the name to ECF.zip. Change it back to ECF.jar. Then just double click on the file and it starts directly. You can also download sample models ECFModels.zip and unzip to a model directory.
Developers can find the Java Runtime Environment and ECF source code here.
The theory of Economic Circular Flows (ECF) is described on www.ecf-theory.se.
