The method Economic Circular Flows (ECF, updated 2016-09-20, Download) is based on principles drawn from the engineering science, circuit theory and control theory. Economic systems are described graphically with charts that are created interactively. Any mathematical equations needed are created and solved automatically in the background.
My method ECF is not tied to a particular economic system. With the economic system, I mean not just capitalism or socialism but also a part of the economy that is inside a so-called system boundary. The system may be a country, a region, a municipality, a business or a household. Inside the system boundary are the interdependencies that define the functioning of the system. Outside the system boundary are external factors that can not be modelled or as we deliberately excluded from the model.

When I studied economics (20p) at the University, I was wondering if the assumptions for micro-economy led to the conclusions of makro-economy.
 Was there any method for coupling the micro with the macro? In engineering science, systems are described interconnected components. I wanted to try the same method on economic systems.

I myself have been thinking about the wording that
Economics is the study of the use of finite resources to satisfy unlimited human wants.[Lipsey]
My own experience of my economic studies is that it mostly is about limited monetary resources. Lack of natural resources is hardly mentioned although we make use of both finite and renewable resources. We even threaten people’s future existence by the climate changes that we are causing.

Eric Gustaf Geijer once wrote… That the new economics is merely “a science of wealth without regard to national happiness, virtue and benefit” [Ord & Bild]
August Strindberg in “Small Catechism of the underclass”. [Strindberg]
A science invented by the upper class to access the fruit of the underclasses job.See further under the tab Models .
